The SMA supply caecum, ascends colon, all of the small bowels except the upper part of duodenum. Knowledge of variable anatomy of celiac axis and SMA may be useful in planning and executing radiological interventions such as celiacography and chemoembolization of hepatic and pancreatic tumors. In this study, the uncommon or low percentage cases of CT and SMA are presented in the light of clinical and embryological information. The celiac axises of a total of 30 adult corpses were examined. Dissections of abdominal region were performed in detail according to Cunningham’s manual. Angiographic images of 100 consecutive adult patients who underwent celiac MDCT angiography were evaluated. During autopsies, an incomplete celiac trunk or bifurcation of celiac trunk associated with the hepatomesenteric and gastrosplenic trunks (0.7%) and a celiacomesenteric trunk associated with high origin superior mesenteric artery and gastrosplenic trunk were detected (0.7%). During MDCT angiography, a case of total absence of celiac trunk associated with a hepatosplenomesenteric trunk (0.7%) and also a case of total absence of celiac trunk alone were observed (0.7%). The persistence or unusual development of ventral splanchnic arteries (VSAs) or ventral longitudinal anastomosis may result in variations or the unusual trunks related to celiac axis and SMA. The anomalous trunks of the CT may be result of either the persistence of some parts of the VSAs or ventral longitudinal anastomose that normally disappear or disappearance of parts that normally persist. The prevalence of unusual trunks of celiac axis and SMA in this study is quite low in literature. These abnormal vessels pose problems for surgeons and radiologists. Such vascular anomalies may cause clinical complications following surgical and radiological procedures such as resection of tumor of the pancreatic head, lymphadenectomy, coeliacography, aortic replacement with reimplantation of the trunk and coembolization of pancreatic and liver tumors.展开更多

According to the literature, these anatomical variants are little known in sub-Saharan Africa. Purpose: To evaluate the prevalence of anatomical variants of celiac trunk in relation to its branching. Materials and methods: This was a cross-sectional study of descriptive type. It retrospectively evaluated 160 abdominal contrast enhanced CT-scan, from patients attending Yalgado OUEDRAOGO teaching hospital, from 1 January 2015 to 30 September 2016. Patients with a history of heavy abdominal surgery were excluded. Images obtained by 64-row CT-scan were analyzed for anatomical variants of the celiac trunk. Results: One hundred and twenty-eight patients (80%) had a classic anatomical configuration of celiac trunk, while thirty-two (20%) had at least one anatomical variant. Two anatomical variants were found in fifteen patients (9.4%) while five other patients (3.1%) had more than two variants. The most frequent anatomical variant was the hepato-splenic bifurcation, found in fourteen patients (8, 8%). It was followed by common celiac and mesenteric trunk, and then collateral arteries, in particular left hepatic artery and right lower diaphragmatic artery, each with three patients (1.9%). Conclusion: Anatomical variants related to celiac trunk branching, are as frequent in our study as in the literature. However, the two most common anatomical variants were hepato-splenic bifurcation and common celiac and mesenteric trunk.展开更多

METHODS Clinical specimens of 241 patients receiving resection of a thoracic esophageal carcinoma were analyzed retrospectively. RESULTS The rate of the patient celiac lymph-node metastases was 32.4%(78/241), and of the lymph nodes examined, 9.8% were found to have metastasis. The extent of metastases adjacent to the common hepatic artery and celiac trunk and within the hepatoduodenal ligaments was 6.6%, 6.9% and 6.3%, respectively. The tumor site, extent of invasion and level of cell differentiation were the factors influencing lymph-node metastases, but they were unrelated to the length of the tumor. The overall rate of regional celiac recurrence for the patients 3 years after operation was 5.4%. The 3-year survivals for the patients with metastases of the celiac lymph nodes was 42.3%, which was lower compared to the non-metastatic patients (70.6%) (P<0.01). CONCLUSION Celiac lymph-node metastases are one of key factors affecting the prognosis of the patients receiving resection of esophageal cancer, and extensive clearance of the celiac-trunk lymph nodes can reduce the rate of postoperative regional metastases.展开更多
