a 52-year-old post-menopausal female was admitted to the emergency room due to acute onset of abdominal pain in the right lower quadrant. there was no history of trauma of the abdomen. contrast-enhanced multi-detector computed tomography (mdct) of the abdomen and pelvis revealed a massive right retroperitoneal hematoma and contrast extravasation from a right ovarian artery aneurysm. digital sub...

Obstructive jaundice by vascular compression is extremely rare. Luttwak and Schwartz first described jaundice due to an obstruction of the common hepatic duct by an aberrant artery.1 Compression of extrahepatic bile duct (EBD) by right hepatic artery was defined as right hepatic artery syndrome. We present here a rare case of asymptomatic biliary obstruction due to compression of the common bil...

PURPOSE The aim of our study was to determine whether using C-arm CT (DYNA CT) during hepatic arteriography imaging assists in TACE treatment. MATERIALS AND METHODS 138 patients with HCC, 69 patients (Group A) underwent DYNA CT and routine digital subtraction angiography (DSA), while another 69 patients (Group B) underwent only DSA, were prospectively studied at a single facility between May ...

Background: The most common hepatic artery complications after Liver Transplantation (LT) are hepatic artery stenosis, thrombosis and pseudoaneurysm, which can all cause ischemia in the grafted liver. As one of the main complications, the Hepatic Artery Pseudoaneurysm (HAP) is rare with the incidence of about 2%, but its consequence may be most devastating or even fatal. Methods: Here, we prese...

OBJECTIVE To review the anatomical variations of the right lobe encountered in 40 living liver donors, describe the surgical management of these variations, and summarize the results of these procedures. SUMMARY BACKGROUND DATA Anatomical variability is the rule rather than the exception in liver and biliary surgery. To make effective use of liver segments from living donors for transplantati...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...

PURPOSE This study demonstrated invasive and reproducible hepatic artery catheterization in rats. A rigorously documented guide and pictorial essay describes the performance of an invasive hepatic artery catheterization technique suitable for the study of liver-targeted interventional procedures in rodent models of liver cancer. The goal was to produce a well-illustrated guide to hepatic artery...

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis involving predominantly medium-sized muscular arteries. It commonly involves skin, kidney, cardiovascular system, gastrointestinal system, and neurological system. But bronchial artery involvement of PAN is rarely identified. We report a case of PAN with initial presentation of hemoptysis. On admission, chest radiograph and chest C...

BACKGROUND Nonalcoholic fatty liver disease is associated with a risk of coronary artery disease (e.g., diabetes mellitus, dyslipidemia, metabolic syndrome). We evaluated whether nonalcoholic hepatic steatosis is associated with high-risk plaques as assessed by multidetector computed tomography (CT). METHODS This retrospective study involved 414 participants suspected of having coronary arter...

BACKGROUND The identification of the dorsal sector of the liver and its detailed vascular anatomy is of primary importance for surgical practice and segmental transcatheter arterial chemoembolization. OBJECTIVES This study aimed to investigate the feeding arteries of tumors in dorsal sector of the liver. PATIENTS AND METHODS Computed tomography (CT) and digital subtraction angiography (DSA)...
