Abstract

WOS: 000248998100016 The superior cerebellar artery (SCA) is often described as the most consistent artery of the infratentorial group. Some variations were noted especially in the proximal part of the artery, such as duplication, triplication, and unusual origin from the basilar artery. It is consistently described as bifurcating into rostral and caudal branches when originating solely from the distal basilar artery. Duplication is mostly encountered as two trunks originating from the basilar artery, with the superior trunk bearing rostral and the inferior trunk caudal branches, respectively. In 14 brains with 28 superior cerebellar arteries, which form the basis of this article, the majority of the duplications were related to the basilar-artery origin of a marginal branch that is also one of the cortical branches of the SCA. Moreover, this kind of proximal origin of the marginal branch resulted in its being richer in perforators than one of distal origin. Other variations that were noted in our study were also those related to marginal branches. The majority of duplications of the SCA were related to the basilar-artery origin of the marginal branches. A proximal origin seems to confer on the marginal artery the property of being an important supplier of perforators. This perforator dominancy, as a result of proximal origin, of the marginal artery might be important clinically in cerebellopontine angle and clivus surgery.

Abstract

WOS: 000312709400031, PubMed ID: 22851047, To assess the efficacy of extended lymph node dissection in gastric cancer and to identify factors affecting lymph node detection. A prospective study of 126 gastric cancer patients was conducted. Patients eligible for curative resection received total gastrectomy and extended lymphadenectomy (D2) and paraaortic lymph node sampling as the standard of care (study group). Supramesocolic total lymphadenectomy of the upper gastrointestinal tract was performed on 23 autopsy cases as a control group. Fifty-five gastric carcinoma patients were included in the study group. Median age was 58 years (range 31-80 years); 14 patients were female (25 %), and 41 were male (75 %). The median number of lymph nodes harvested from the specimen was 47 (24-95), and the median number of metastatic lymph nodes was 15 (1-71). In contrast, in the autopsy comparative group, the median number of harvested lymph nodes was 72 (50-91). The median number of stational lymph nodes excised (lymph nodes excised from stations 4, 5, 10, 11, 12, and 16) was significantly higher in the control group than in the study group (P < 0.05). Lymph node detection was adversely affected by body mass index (BMI) (P < 0.03). In the study group, stations 5, 12, 11, and 10 had the highest lymph node absence (LNA) (noncompliance) ratio with percentages of 53, 36, 33, and 22 %, respectively. In the autopsy group, LNA (noncompliance) was not detected. Lymph nodes should be dissected by surgeons with sufficient technical and anatomical experience, and then examined and counted by experienced pathologists to reduce the occurrence of LNA. The results of this anatomical study can serve as a guideline to assess the success of lymph node dissection during gastric cancer surgery. Similar studies should be conducted in every country to establish national guidelines.

Abstract

In any kind of diving there is a risk of accidents, as the move from the topside environment to underwater can affect a diver’s physiological and psychological condition. It is important to investigate dive accidents to clarify the causative factors and determine preventive measures. In this study, autopsy files of fatal dive accident cases were reviewed to evaluate demographic data, type of diving, purpose of dive, seasonal distribution, autopsy findings, and causes of death. We reviewed 56 fatal dive accident files from autopsy units in cities where dive activities are concentrated and from the archive of the Turkish Underwater Federation. Four cases were excluded from the study since we were unable to obtain autopsy reports. Of 52 cases there were 20 scuba divers, two surface-supplied divers and 30 breath-hold divers. The majority of cases involved males (94%). The average age of 50 cases was 38.6; age estimation for two cases could not be determined due to advanced putrefaction. Of these fatal dive accidents 75% took place over a period of six months between May and October. Drowning was recorded as the primary cause of death in these cases. X-ray imaging was used in four (8%) cases. A special autopsy technique was used for nine (17%) cases, to detect possible pulmonary barotrauma and arterial gas embolism. The forensic specialist who is planning to conduct the autopsy for a dive fatality should have knowledge and experience about dive physics and physiology as well as physiopathology of dysbaric injuries., Competing Interests: The authors of this paper declare no conflicts of interest exist with this submission.autopsy;, (Copyright© Undersea and Hyperbaric Medical Society)

Abstract

Objective: The resection of the odontoid process via an extended endoscopic endonasal approach has been recently proposed as an alternative to the microscopic transoral method. We aimed to delineate a minimally invasive endoscopic transnasal odontoidectomy and to describe the endoscopic anatomy of the anterior craniovertebral junction (CVJ)., Materials and Methods: The anterior CVJ of 14 fresh adult cadavers were selectively accessed via a binostril endoscopic endonasal approach using 0- and 30-degree endoscopes., Results: The nasopharynx was widely exposed without removing any of the turbinates and without performing a sphenoidotomy. Occipital condyles and lateral masses of the C1 vertebra have been exposed inferiorly at lateral margins of the exposure, in addition to the foramen lacerum, which came into view at the superolateral corner of the operative field. The anterior arch of C1 and the upper 1.5 cm of the odontoid process of C2 have been removed via a minimally invasive endoscopic transnasal approach in all dissections., Conclusions: We propose the selective odontoidectomy as a minimally invasive method for the endoscopic endonasal removal of the odontoid process. By using this approach, turbinates and the sphenoid sinus remain unharmed. In addition, this approach may be used in exposing pathologies situated laterally at the anterior CVJ, such as the lateral masses of atlas and occipital condyles.
