An intact hepatic artery is the gateway to successful hepato-biliary surgery. Introduction of laproscopic cholecystectomy (LC) has stimulated a renewed interest in the anatomy of hepatic artery. In this case report we have highlighted importance of variations of right hepatic artery in terms of origin and course We present a rare asymptomatic case of liver atrophy due to an intraoperative lesio...

BACKGROUND Curative hepatectomy with bile duct resection is the treatment for perihilar cholangiocarcinoma. A locally advanced tumor necessitates hepatectomy with simultaneous vascular resection, and reconstruction remains an obstacle for surgeons. Studies have focused on the variations of hepatic arteries. Nevertheless, the anatomical alignment of the portal veins, bile ducts, and hepatic arte...

PURPOSE Dilatation of the hepatic artery in response to decrease in portal vein flow is known as hepatic arterial buffer response (HABR). In this study, the effect of HABR on variant hepatic arterial anatomy is investigated by analyzing the frequency of the right hepatic artery originating from the superior mesenteric artery (variant artery) and by determining the diameters of variant artery an...

Ruptured hepatic artery aneurysm is a rare life-threatening condition. Open surgery with ligation of the aneurysm is the treatment of choice if the patient presents with haemodynamic instability. Controversies exist on whether hepatic artery reconstruction is needed after exclusion of the aneurysm. Involvement of the gastroduodenal artery origin was proposed as an indication for reconstruction,...

Introduction: The knowledge and realization of the frequency and multiplicity of abnormalities of the cystic artery is aperquisite for safe laparoscopic cholecystectomy. Objective:To describe the morphological characteristics of the cystic artery in the triangle of Calot. Methods: Descriptive-prospective cross sectional study was performed in 200 patients, who underwent laparoscopic cholecystec...

INTRODUCTION Each hepatic artery is functionally essential for providing blood supply to the liver, and so are variant arteries. Variant arteries, including the accessory right hepatic artery (ARHA) and replaced right hepatic artery (RRHA) are commonly described in the literature. However, they usually occur independently. Here, we report an extremely rare case that involved both an ARHA and an...

Objective To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. Materials and Methods This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. Results The ...

Regional infusion chemotherapy for the treatment of primary or secondary hepatic cancer should allow delivery of a higher drug concentration to the tumor with decreased systemic exposure when compared with systemic therapy. Fifteen rabbits, each implanted with two hepatic Vx-2 tumors, were treated with infusion of Adriamycin (3 mg/kg and 7.5 muCi of [14C]Adriamycin) through the hepatic artery (...

Colonic arteriovenous malformations (AVMs) are well recognized in the literature and commonly manifest as colitis, abdominal pain, rare cases have been reported of liver congestion. Dual-supply superior artery/ inferior mesenteric artery (SMA/IMA) colonic AVMs never only one case treating portal hypertension due to an AVM with endovascular approach has reported. We present a dual-supply SMA/IMA...

Hepatic artery aneurysms are rare but potentially life threatening. We describe a novel case of a successful endovascular coil embolization of a huge hepatic artery aneurysm. A 67-year-old woman presented with recent abdominal pain that had begun from 2 weeks before referring to our hospital. Sonographic and computerized tomographic (CT) findings revealed a huge hepatic artery aneurysm with 95 ...
