Résumé
The coeliac trunk is the branch of the abdominal aorta at the level of the twelfth thoracic vertebra. Its branches namely left gastric, common hepatic and splenic arteries supply the primary organs of the supracolic abdominal compartment namely the stomach, pancreas, spleen and liver. In this article, we report case series of three cases in male cadavers aged 65yrs, 60yrs and 70yrs respectively in the Department of Anatomy, Pondicherry Institute of Medical Sciences and MVJ Medical College and Research Institute wherein we discovered that the branching pattern of the coeliac trunk varied from the usual pattern, thus the specimens were photographed to understand further. The observation of first case, common trunk from abdominal aorta showed common hepatic and superior mesenteric artery and left gastric and splenic artery aroused as another common trunk from abdominal aorta. The second case showed the superior mesenteric artery arising from coeliac trunk and the third case was observed the inferior phrenic arteries were arising from coeliac trunk. Knowledge of this variable anatomy may be useful in planning and executing surgical or radiological interventions.

Objective: To investigate the variants of middle colic artery (MCA) and ileocolic vein (ICV) and their influence on the deci-sion regarding approach of laparoscopic right hemicolectomy. Methods: We analyzed the diagnosis and treatment of one right colon cancer patient with variant MCA and ICV who was admitted to the Tianjin Medical University Cancer Hospital in March 2018. The pa-tient underwent laparoscopic right hemicolectomy via a limited medial approach after a multidisciplinary treatment (MDT) discussion. Following were the observation indicators: 1) surgical and postoperative recovery situations; 2) postoperative pathological examina-tion; and 3) follow-up situation. Results: 1) Surgical and postoperative recovery situations: the patient successfully underwent laparo-scopic right hemicolectomy via a limited medial approach. No intraoperative or postoperative complications occurred. Duration of postoperative hospital stay was 11 days. 2) Postoperative pathological examination: the number of dissected lymph nodes was 39. Postoperative pathological tumor stage was pT3N0. Postoperative pathological tumor type was moderately differentiated adenocarci-noma. 3) Follow-up situation: the patient was followed-up for 10 months with disease-free survival. Conclusions: Individual and stan-dard surgery will be the best choice for treating colon cancer patients. MDT can facilitate clinical decision-making and benefit patients.
Résumé
Context: Many different patterns have been described to classify the origins of circumflex femoral arteries by many authors since from 1860.The aim of the present study was to classify the circumflex femoral arteries in 100 lower limbs of adult cadavers of both sexes following the recent classification and to compare with the previous studies. Materials and Methods: A total of 100 lower limbs of 50 embalmed human adult cadavers (Male: 37, Female: 13) were dissected and observed for the origins of circumflex femoral arteries in femoral triangle in routine educational dissection in the period of 2005-2009 Results: The medial and lateral circumflex femoral arteries have been classified into three different patterns based on the levels of their origin. Pattern I: Both arteries arose from the profunda femoris artery (56%). Type Ia, medial circumflex femoral artery origin was proximal to the lateral circumflex femoral artery origin (69%); Type Ib, lateral circumflex femoral artery origin was proximal to medial circumflex femoral artery origin (16 %); Type Ic, both arteries arose from a common trunk or at same level (14%). Pattern II: One of the arteries arose from the femoral artery and the other from the profunda femoris artery (36%). Type IIa, the medial circumflex femoral artery arose from the femoral artery (75%) and Type IIb, the lateral circumflex femoral artery arose from the femoral artery (25%).Pattern III: Both arteries arose from the femoral artery (7%). The medial circumflex femoral artery was absent in a female cadaver on right side. Conclusion: In every pattern or type, there was significantly unilateral higher occurrence than bilateral occurrence. A precise knowledge of the circumflex femoral arteries in relation to the profunda femoris artery is important in surgical interventions of the hip region.
Résumé
Objective To review the three-dimensional characteristics and configuration of cranial base arteries of patients with intracranial berry aneurysms. Methods All the 70 patients with intracranial berry aneurysms (83 cases)were admitted from January to December in 2007. Their images of spiral computer angiography (CT) were presented and analyzed retrospectively. The site, size and figures of aneurysms were recorded, especially the variations of cranial base arteries were analyzed. Results Cerebral anterior communicating artery (ACoA) was the frequent site where aneurysms located. Incidence of ACoA aneurysms was 43.37%(36/83), that of posterior communicating artery (PCoA) was 28.92%(24/83), that of internal carotid artery was 9.64% (8/83), that of middle cerebral artery was 6.02% (5/83), that of A1-A3 was 3.61% (3/83), that of basilar artery was 3.61% (3/83), that of posterior cerebral artery was 2.41% (2/83), that of posterior inferior cerebellar artery was 1.20% (1/83),that of anterior choroidal artery was 1.20% (1/83).The shape of many berry aneurysms was regular. Mutational rate of cranial base arteries among aneurysms were 56.63% (47/83) and ACoA ancurysms with A1 dysplasia rate was 72.22% (26/36). Conclusions The solid shape and vascular variation of intracranial berry aneuryams can be optimally identified by spiral computer angiography. The occurrence of berry aneurysms might be associated with variation of cranial base arteries.
Résumé
The knowledge of vascular variations, like other anatomical variations, is important during the operative, diagnostic and endovascular procedures in abdomen. Variations in the branching pattern of the common hepatic artery often occur and may be encountered during cholecystectomy. This report describes a variation in the origin of cystic artery from the gastro duodenal artery as found during routine dissection in an approximately 34 years old male cadaver. The embryological development and clinical implications of such a variant have been discussed in the article.
El conocimiento de las variaciones vasculares, al igual que otras variaciones anatómicas, son importantes durante los procedimientos operativos, diagnósticos y endovasculares en el abdomen. Variaciones en el patrón de ramificación de la arteria hepática común se producen con frecuencia y pueden ser encontradas durante la colecistectomía. Este informe describe una variación en el origen de la arteria cística desde la arteria gastroduodenal encontrada durante la disección de rutina, en un cadáver de sexo masculino, de aproximadamente 34 años. El desarrollo embriológico y las implicaciones clínicas de esta variante son debatidas en el artículo.
