Opis:: Introduction. Although there are lots of varieties of aorta arch, they seem to appear relatively rarely. Anomalies of aortic arch departures are mainly concerned with its location, course, the place of departure and number of its main branches. However, they warrant attention due to their importance in operative, diagnostic, and endovascular procedures. Aim. We want to present here a case of a female cadaver with rare aortic arch origin of the left vertebral artery. The aim of this article is to complete the frame of anomalies in aortic arch and to explore rare variability shown in this specific case. Description of the case. The present report describes an anomalous case of the left vertebral artery arising from the aortic arch between the left common carotid artery and the left subclavian artery in a female cadaver during dissection in an anatomical laboratory. Aortic origin of the vertebral artery is a rare anatomic variant. Conclusion. Thorough knowledge of anomalous origin is important for patients who undergo operation of an aortic arch or inferior part of the neck. Normally, the vertebral artery arises from the first part of the subclavian artery on both sides.

Tematy:: carotid dissection
ischemic stroke
Opis:: The dissection of the internal carotid artery, although rare, is in five to twenty-five percent a causative agent of acute ischemic stroke in patients up to the age of 45. The aim of this paper is to present the case of ischemic stroke within the right hemisphere with left-sided uncomplicated dissection of the internal carotid artery in the case of a young woman. A 35-year-old patient was admitted to the Department of Neurology on an emergency basis due to the sudden motor dysphasia and paresis of the right upper limb. During the anamnesis, the woman reported a head injury suffered two days earlier as a result of fainting. Diagnostic procedures toward ischemic stroke indicated a presence of hypodense area within the left hemisphere of the brain. Subsequent studies – MRI, CT angiography confirmed the existence of an ischemic lesion in the area of the left middle cerebral artery as a consequence of obstruction of the left internal carotid artery. In addition, a dissection of the right internal carotid artery was revealed. Further differential diagnosis, including systemic diseases, did not reveal the reasons for the coexistence of ischemic stroke and vessel dissection on the opposite side. Carotid dissection is a rare but dangerous condition. It either develops spontaneously or after an injury to the head or neck. Any kind of injury of the carotid artery can cause dissection and should lead to include this condition in the differential diagnosis- the more so since even small dissection of the internal carotid artery can be manifested with a delay.

Opis:: The aim of the study was to analyse early results of treatment of acute type B aortic dissection.Material and methods. 59 patients, treated between 1998 and 2011, were divided into four groups. Group I comprised ten patients in whom hybrid procedures were performed: extra-anatomical by-pass graft from the brachio-cephalic trunk to the left carotid artery in six patients, transposition of the left carotid artery to the right one in two patients, and reversed Y prosthesis from the brachio-cephalic trunk to both carotids in the remaining 2 patients, to facilitate stent-grafting. Group II comprised 13 patientsin whom endovascular procedures were performed (stent-grafting). Group III comprised 21 patients in whom conventional surgery was done. Group IV comprised 15 patients who were treated conservatively.Results. In group I, a very good clinical outcome, without complications, was achieved in six patients (60% of cases). The total mortality rate was 40%. One patient died on the operation table, following stent-grafting, due to the rupture of the aortic arch. Two patients died as a result of brain damage (cerebral aneurysm rupture in one, and ischemic stroke in the other). In one patient, an aorto-oesophageal fistula developed. In group II, one patient died during endovascular procedure. Another patient suffered from type 1 endoleak, requiring repeated endovascular surgery. In group III, 15 patients (72%) died. Moreover, four patients required acorrective cardiac surgery (Bentall procedure)which in three patients resulted in death. Thus, the total mortality rate in this group was as high as 85%. In group IV, the mortality rate was 13%.Conclusions. We noticed a clear superiority of endovascular procedures over conventional surgeries-for acute type B aortic dissection. Hybrid procedures for acute, complicated type B aortic dissection evidently reduce mortality and postoperative morbidity. Uncomplicated acute type B aortic dissections should be treated conservatively at intensivecare units.

Opis:: Colonoscopy is a routine diagnostic and therapeutic procedure. Along with the increase in the complexity of the procedures performed, the risk of complications increases. In 2017, WSES (World Society of Emergency Surgery) published the principles of safe colonoscopy. Intestinal perforation is one of the most common complications. The risk of perforation in treatment procedures such as mucosectomy or endoscopic dissection is significantly greater than the risk of diagnostic colonoscopy. The basic rule of the procedure in case of suspected perforation is close supervision over the patient’s condition and the soonest possible repair of damage. The role of the endoscopist is not only early recognition, but also early treatment of damage. Immediate endoscopic treatment of lesions is an effective, final and acceptable management strategy. In patients who have undergone imaging diagnostics for another reason, free gas in the peritoneal cavity can be recognized. It does not have to mean the need for urgent surgical intervention. Patients with asymptomatic pneumoperitoneum after colonoscopy should, however, be treated as patients with suspected perforation of the large intestine and undergo careful clinical observation in accordance with WSES recommendations. Colonoscopy is a procedure with a risk of complications, which should be reported to patients qualified for endoscopy, but appropriate management reduces the risk of morbidity and mortality associated with this procedure.

Opis:: Introduction: Tumors of large salivary glands constitute about 2–3% of all head and neck tumors. Their incidence is statistically greater in males than in females, with the first symptoms usually appearing between the 4th and 7th decade of life. Aim: The aim of the study was to assess the usefulness of the new classification proposed by European Salivary Gland Society (ESGS) in comparison with the divisions of procedures previously valid in the literature, making a retrospective analysis of patients operated on due to benign tumors of large salivary glands in the Department of Otolaryngology, Head and Neck Oncology of the Medical University of Lodz in 2012–2020. Material and methods: The retrospective examination was based on the material consisting of: surgical protocols, histopathological results, imaging results and clinical observations. The material includes 283 patients (141 women and 142 men): 249 patients with parotid gland tumor and 34 patients with submandibular gland tumor. The most common histopathological diagnosis was pleomorphic adenoma, which was found in 105 patients (42.17%) and adenolymphoma diagnosed in 94 patients (37.75%). Results: The most common type of surgery was superficial parotidectomy including total superficial parotidectomy in 86 patients (34.54%) and partial superficial parotidectomy in 49 cases (19.68%). Then, according to the frequency of surgery, extracapsular tumor dissection (ECD) was performed (91 patients – 36.55%). According to the ESGS classification, in most cases parotidectomy I, II (37.34% of all parotidectomies) and parotidectomy II (28.49%) were performed. In case of ECD, all tumors were located at level II. Conclusions: In summary, the new classification is aimed at unifying, but also simplifying the current nomenclature, reducing the existing nomenclature errors. Determination of the exact location and extent of the tumor within the parotid gland facilitates postoperative monitoring of patients by ENT doctors and those of other specialties.

Opis:: Introduction and aim. Cadaveric dissection is the mainstay of learning anatomy by medical students. Even though newer teaching learning methodologies have been implemented to facilitate learning anatomy, cadaveric dissection remains the most preferred method by students. The objective of this study was to analyze the student perspective of different aspects of learning anatomy with their positive and negative experiences and to get a better understanding of their opinions and their experience. Material and methods. In this cross-sectional study, a pretested and validated questionnaire was used to collect information from the students after approval from the Institutional Ethics Committee. Informed consent was obtained from every student prior to their participation in the study. Results. Three hundred seventy-seven students took part in this study and the response rate obtained was 63.5%. The majority of the students stated that cadaveric dissection has helped them in learning basic anatomy and had deepened their understanding of complexity of human body and has helped in better performance in clinical applications. The smell of formaldehyde and eye irritation was cited as the major reasons for finding dissection sessions challenging. Most of the students agreed that counselling before dissection sessions will help to alleviate the emotional reactions to cadavers. Conclusion. The students unanimously agreed that cadaveric dissection sessions are the best way to learn basic anatomy complemented with newer teaching tools like prosection and computer-based approaches. However, the problems encountered by the students like smell and irritation of formaldehyde need to be addressed with usage of alternative techniques.

Opis:: “Lower Lid Blepharoplasty-Entropion-Ectropion Oculoplastic Procedures Cadaveric Dissection Course” was performed in Bahcesehir University School of Medicine on February 19th, 2017 with the participation of 20 ophthalmologists. Lower eyelid anatomy, lower eyelid entropion-ectropion surgical techniques, subciliary and transconjunctival approach to lower eyelid blepharoplasty, prevention and management methods of surgical complications were shown on the fresh frozen cadaveric eyelids. All the participants were able to follow anatomic demonstrations and surgical techniques performed on the master table by experienced surgeons through live broadcasting. The stages of the lower eyelid cadaveric dissection and details of the anatomical structures were presented to the participants by the recording, reproducing, or broadcasting of moving visual images. Cadaveric workshops as a primary modality of simulation based surgical skills training have been used for a few years in Turkey. Although cadaveric dissection training has some disadvantages such as tissue loss, degeneration of anatomical key points, diversification in the structure, lack of experience in live tissue tonus, difficulties in providing cadavers, and high cost; it is the gold standard technique for surgical skill transfer in eyelid surgery.

Opis:: Aortic dissection is a life-threatening condition, in which rupture of the internal wall of the aorta is observed. The aim of the study was to present the techniques used in patients with type A Stanford aortic dissection treatment by means of carotid-carotid by-pass surgery and implantation of the aortic stent-graft with intentional occlusion of the left common carotid and subclavian arteries. Surgical methods were presented on the basis of three patients treated at the Department of Vascular, General and Oncological Surgery, Memorial Copernicus Hospital in Łódź. Different carotid- carotid bypass grafting techniques were also described. Our own clinical observations demonstrated that patients with retro-pharyngeal carotid-carotid bypass did not report dysphagia, and retropharyngeal grafting seems to be the optimal method considering patients in whom stent-grafts cause left carotid artery occlusion.

Opis:: Introduction: Postoperative injury of the marginal mandibular branch of the facial nerve is considered a complication in neck dissection and can be related to different factors including traction, devascularisation or conduction block due to diathermy. Material and Methods: A prospective, crossover study including patients treated via bilateral selective neck dissection level IIa during a 12-month period, was performed to evaluate efficacy of the Hayes-Martin manoeuvre to prevent nerve injury during use of cold or monopolar diathermy dissection. Results: 20 patients met the inclusion criteria (40 neck dissections). Just one case of right temporal MMN weakness in the postoperative period was observed (1/40 = 2.5%). There were no cases of permanent marginal mandibular nerve weakness when using the Hayes-Martin manoeuvre. Conclusion: he Hayes-Martin manoeuvre is a safe method to preserve MMN during neck dissection level IIa, regardless of the type of dissection.

Opis:: The aim of the presented work is to determine (i) mechanical properties of the ascending aorta wall (DAA) and the wall of the ascending aortic aneurysm (DAAA), in which spontaneous dissection resulting from the evolving disease occurred, and (ii) the strength of the interface between the layers in the above-mentioned vessels. Methods: The mechanical tests were divided into two steps. In the first step the mechanical properties of the of DAA and DAAA walls were examined on the basis of uniaxial stretching until rapture. In the next step the mechanical parameters of the interface between layers of DAA and DAAA walls were determined by the peeling test. Results: Higher values of tensile strength (max) and Young’s modulus (E) were obtained for the DAAA group, to which the dissecting wall of the ascending aortic aneurysm was classified. For circumferential samples, the difference between the DAAA and DAA groups was 39% in the case of tensile strength and 70% in the case of the Young’s modulus. Conclusions: Summarizing, the studies performed showed that the dissection process is different in the case of the ascending aortic aneurysm wall and the ascending aorta wall. The wall of the ascending aortic aneurysm is more susceptible to dissection, as evidenced by lower values of the mechanical parameters of the interface between the intima and the media-adventitia complex. The obtained results of mechanical properties tests confirm that dissection and aneurysm should be treated as separate disease entities that may coexist with each other.

Opis:: Rozwarstwienie jest jedną z najpoważniejszych chorób aorty. Nową metodą leczenia rozwarstwienia aorty jest technika endowaskularna. Celem pracy jest ocena skuteczności leczenia endowaskularnego rozwarstwień aorty typu B oraz częstości powikłań i śmiertelności związanych z zastosowaniem tej techniki. Materiał i metoda: U 33 pacjentów na podstawie badania angiograficznego lub TK rozpoznano rozwarstwienie aorty, typu A u 2 (6,1%) i typu B u 31 (93,9%). U 11 pacjentów (33,3%) zastosowano leczenie z wykorzystaniem trzech typów stent-graftów: Zenith (2 protezy - 13,3%), Talent (11 protez - 73,3%) i Valiant (2 protezy - 13,3%). W 3 przypadkach zaistniała konieczność zastosowania więcej niż jednego stent-graftu (u dwóch pacjentów po 2 stent-grafty, u jednego 3). Średnica proksymalnego końca implantowanego stent-graftu wynosiła od 34 do 42 mm (średnia 37,6 ± 3,44 mm), natomiast długość wahała się w granicach od 130 do 230 mm (średnia 183,6±37,42 mm). U 4 pacjentów (36,4%) w trakcie implantacji konieczne było częściowe, a u 2 (18,2%) całkowite pokrycie odejścia LSA. Wyniki: U jednego pacjenta (9,1%), nastąpił zgon w 13 dobie po implantacji. Zabieg endowaskularny w 9,1% był powikłany wystąpieniem endoleaku typu II, w 18,2% zespołem poimplantacyjnym, w 9,1% przeciekiem do lewej jamy opłucnowej wymagającym implantacji drugiego stent-graftu. W jednym przypadku w celu uniknięcia powikłań neurologicznych i zespołu podkradania zastosowano rewaskularyzację LSA. Wnioski: Zastosowanie stent-graftów wychodzi naprzeciw ogólnemu dążeniu do minimalizacji rozległości i traumatyzacji zabiegów chirurgicznych, redukcji liczby około- i pooperacyjnych powikłań, skrócenia czasu hospitalizacji i rekonwalescencji.
Aortic dissection is one of the most catastrophic aortic disease. Endovascular technique using endovascular prostheses called stent-grafts offers less invasive new method. purpose: Assessment of endovascular aortic dissection type B treatment effectiveness, complications and mortality frequency associated with this technique. Material and methods: Among 33 patients aortic dissection diagnosis was established on the basis of angiography and CT; type A – 2 patients (6.1%) and type B – 31 (93.9%). 11 patients (33.3%) underwent endovascular stent-grafts implantation procedures using 3 types of grafts: Zenith (2 prostheses – 13.3%), Talent (11 prostheses – 73.3%) and Valiant (2 pros - theses – 13.3%). There was necessity of implantation of more than one stent-graft in 3 cases (2 patients – 2 stent-grafts, one patient – 3 stent-grafts). The diameter of proximal end of stent-graft ranged from 34 to 42 mm (mean 37.6 ± 3.44 mm), length – from 130 to 230 mm (mean 183.6 ± 37.42 mm). 4 patients (36.4%) needed partial, and 2 – complete coverage of the LSA during implantation. Results: One patient (9.1%) died on the 13 th day after implantation. Endovascular procedure in 9.1% was complicated by endoleak type II, in 18.2% - post - implantation syndrome, in 9.1% leakage to the left pleural cavity requiring second stent-graft implantation. The LSA revascularization was performed in one patient in order to avoid neurological complications and steal syndrome Conclusions: Endovascular technique is promising strategy of aortic dissection type B treatment. Stent-graft application faces up to general aspiration to minimize extension and traumatization of surgical procedures, to reduce peri- and postoperative complications, decrease hospitalization and convalescence period.

Opis:: Introduction: This study was conducted to correlate the personal formaldehyde (FA) exposure levels of instructors and students with the indoor FA concentrations in gross anatomy laboratory at King Saud University. The personal FA levels of instructors and students are higher than the indoor FA concentration in the gross anatomy laboratory. Materials and Methods: The gross anatomy laboratory at college of medicine, King Saud University Riyadh, was observed for indoor FA concentration and the personal exposure levels of instructors and the medical students during the 4th, 10th and 14th weeks of the dissection sessions. All air samples were collected by the diffusive sampling device and analyzed by using high performance liquid chromatography (HPLC). Results: The personal exposure level of FA was higher than the indoor concentration, and the personal exposure levels of instructors were higher than that of the students. The concentration of FA was also higher in the center of the room than the corners and near the doors. Conclusion: Both the indoor FA concentrations and personal FA exposure levels are higher near the dissecting table than at locations away from it during the gross anatomy laboratory sessions. Thus, the instructors and students are exposed to the higher concentration of FA than the general population.

Opis:: The ability to produce large number of embryo from donor of high genetic merit using assisted reproductive technology has a considerable potential value. It is vital in disseminating genetic improvement, shortening the progeny testing and generation interval. Live animal and slaughter house ovary are good source of oocytes for in vitro embryo production. Oocytes are recovered from ovaries of slaughtered animals by using needle aspiration, slicing, aspiration and dissection or dissection alone as a method of recovering oocytes. In vitro embryo production from live donors through laparoscopic methods of oocyte recovery or transvaginal oocyte recoveries are extremely versatile techniques because they can be applied to donors of all ages from two-month-old calves to very old cows.
