Surgical anatomy of the accessory middle colic artery: a meta-analysis with implications for splenic flexure cancer surgery.

Evaluation of vascular anatomy for colon cancer located in the splenic flexure using the preoperative three-dimensional computed tomography angiography with colonography.

Evaluation of the vascular anatomy of the left-sided colon focused on the accessory middle colic artery: a single-centre study of 734 patients.Preoperative evaluation of this anatomy may be beneficial for lymph node dissection during left-sided hemicolectomy. In some patients these vessels were located on the dorsal side of the pancreas and not below it.

CONCLUSION: The SFV was observed in most patients, and the LCA or AMCA was the common accompanying artery. Similarly, the destination of the IMV was located on the dorsal side of the pancreas in 65 (31.7%) of patients. The origin of the AMCA was located on the dorsal side of the pancreas in 15 (20.3%) of these 74 patients. In 15 (7.8%) patients, no artery accompanied the SFV. The AMCA accompanied the SFV in 65 (32.7%) patients. The left colic artery (LCA) was the major artery accompanying the SFV in 87 (42.4%) of patients. RESULTS: The AMCA was observed in 74 (36.1%) patients whereas the SFV was found in 177 (86.3%) patients. The locations of the AMCA and IMV were evaluated, focusing on the positional relationship between the vessels and pancreas - below the pancreas or to the dorsal side of the pancreas. METHOD: Two hundred and five patients with colorectal cancer who underwent enhanced CT preoperatively were enrolled in the present study. Herein, we aimed to evaluate the anatomy of the AMCA and the splenic flexure vein (SFV). However, the positional relationship between the AMCA and inferior mesenteric vein (IMV) has not been evaluated. N2 - AIM: Recently, the accessory middle colic artery (AMCA) has been recognized as the vessel that supplies blood to the splenic flexure.
