PURPOSE: To establish a method by which angiography of the inferior mesenteric artery (IMA) can be performed smoothly, we investigated the relative locations of the coeliac trunk (CT), superior mesenteric artery (SMA), IMA, and left renal artery (LtRA). METHODS: From a total of 60 cadavers, 32 cadavers with few arteriosclerotic lesions and little vascular tortuosity were selected for the study. The abdominal aorta (Ao) were removed and incised on both lateral side, along the vertical axis and transected into the ventral and dorsal sides...

Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare carcinomatosis limited to the peritoneal cavity, mainly supplied by the superior mesenteric artery (SMA). The only curative treatment is cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy. This study aimed to evaluate the ability of blood flow volume (BFV) recorded in the SMA using Doppler ultrasonography pre-operatively to predict the extent and resectability of the disease and post-operatively to assess clinical outcome...

OBJECTIVE: The development of atherosclerotic plaques and spontaneous isolated dissection (SID) of the superior mesenteric artery (SMA) was considered to be related to opposite haemodynamics. The purpose of this study was to compare their occurrence sites and the morphology of the SMA to confirm the haemodynamic aetiologies. METHODS: 57 patients with SID and 64 patients with atherosclerotic plaques were compared about patient characteristics, location of SID and plaque, the distance from lesion to the aortic ostia, SMA branching angle and inlet diameter of the SMA...

INTRODUCTION: Celiac axis occlusion is a challenging condition when catheterization of the hepatic artery is required for chemoembolization of hepatocellular carcinoma (HCC). As a result, the hepatic artery has to be catheterized through the pancreaticoduodenal arcades (PDA) and the gastroduodenal artery (GDA) from the superior mesenteric artery (SMA) which is a tortuous course with acute angles and small caliber branches. OBJECTIVE: To assess new techniques for facilitating catheterization of the tortuous PDA and the GDA to reach the proper hepatic artery (PHA) and tumor-feeding branches in patients with celiac axis occlusion undergoing chemoembolization of HCC...

We report a case of inferior mesenteric artery aneurysm after the replacement of the thoracoabdominal aorta for a chronic dissected thoracoabdominal aortic aneurysm in which the celiac artery and superior mesenteric artery were occluded. We performed the resection of the inferior mesenteric artery aneurysm and the revascularization of the superior mesenteric artery, inferior mesenteric artery, and the meandering artery. The patient's postoperative course was uneventful, without bowel ischemia. From the findings of intraoperative flow measurement of the visceral arteries, revascularization of the SMA was judged to be appropriate in this situation...

INTRODUCTION: Hereditary Hemorragic Telangiectasia (HHT) is a rare disease consistent in vascular dysplasias affecting different organs. Liver involvement includes telangiectases, arteriovenous shunting, and ischemic cholangitis, and its prevalence ranges from 8 to 31%. Spontaneous pseudo aneurysms have never been reported associated to HHT. Several variations in the origin of the main hepatic artery (MHA) have been described in large radiological series, and can be found in around 4% of general population...

Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old boy who had a history of idiopathic scoliosis and presented with bilious vomiting that had persisted for 7 days after posterior T9-L4 fusion with instrumentation...

BACKGROUND: Resection of the superior mesenteric artery (SMA) during pancreatectomy is performed infrequently and is undertaken with the aim of removing non-metastatic locally advanced pancreatic tumours. SMA resection reports also encompass resection of other visceral vessels. The consequences of resection of these different arteries are not necessarily equivalent. This is a focused systematic review of the outcome of SMA resection during pancreatectomy for cancer. METHODS: A computerized search of the English language literature was undertaken for the period 1st January 2000 through 30th April 2016...

BACKGROUND: Laparoscopic distal pancreatectomy (Lap-DP) for benign lesions or those with low malignant potential has been proven safe and effective, and its performance is now widespread [1-3]. Lap-DP for left-sided pancreatic cancer (PC) is also being increasingly performed. According to some reports, Lap-DP has superior short-term outcomes (blood loss, postoperative hospital stay) and comparable oncological outcomes and overall survival with those of open distal pancreatectomy (Op-DP) [4-6]...

BACKGROUND: Surgeons, in general, underestimate the replaced left hepatic artery (rLHA) that arises from the left gastric artery (LGA), compared with the replaced right hepatic artery (rRHA), especially in standard gastric cancer surgery. During pancreaticoduodenectomy (PD), preservation of the rRHA arising from the superior mesenteric artery (SMA) is widely accepted to prevent critical postoperative complications, such as liver necrosis, bile duct ischemia, and biliary anastomotic leakage...

Anders Gottsäter
Visceral arteries such as the coeliac (CA), superior mesenteric (SMA), and the inferior mesenteric artery (IMA) might be affected by atherosclerotic occlusive lesions with or without thrombosis or embolization causing ischaemic symptoms from the gastrointestinal tract. After treatment of an acute event, these patients should be offered both non-pharmacological and pharmacological secondary prevention to reduce risk for future ischaemic arterial manifestations. Patients with mesenteric ischaemia caused by atherosclerosis should be evaluated concerning platelet antiaggregation with low dose aspirin or clopidogrel, and those with cardioembolic disease should be recommended anticoagulant treatment with either warfarin or one of the direct oral anticoagulants (DOAC; apixaban, dabigatran, edoxaban, or rivaroxaban)...

BACKGROUND: The superior mesenteric artery (SMA) first approach was proposed recently as a new modification of the standard pancreaticoduodenectomy. Increasing evidence showed that a periadventiceal dissection of the SMA with early transection of the inflow during pancreaticoduodenectomy associates better early perioperative results, and setup the scene for long-term oncological benefits. The objectives of the current study are to compare the operative results and long-term oncological outcomes of SMA first approach pancreaticoduodenectomy (SMA-PD) with standard pancreaticoduodenectomy (S-PD)...
