OBJECTIVES To compare estimated remnant liver volume (ERLV) ratios among the major main portal vein (MPV) variants. METHODS Eighty-five potential donors underwent multidetector CT examination. Arterial, portal and hepatic venous phase images were obtained. CT volumetric measurements were performed by using summation-of-area method. MPV variants were(More)
PURPOSE To compare doxorubicin-loaded HepaSphere transarterial chemoembolization versus conventional transarterial chemoembolization in terms of survival, time to recurrence, acute reversible hepatotoxicity, postembolization syndrome, and chemoembolization-related mortality and morbidity. MATERIALS AND METHODS One hundred twenty-six patients (103 men, 23(More)
OBJECTIVE Subarachnoid hemorrhage (SAH), which can cause mortality and severe morbidity, is a serious condition whose underlying cause must be determined. We aimed to compare 2D digital subtraction angiography (2DDSA), rotational angiography (RA) and 3D volume rendering digital subtraction angiography (3DVRDSA) for detecting aneurysms and their(More)
PURPOSE To determine the safety, efficacy, and long-term results of percutaneous biliary balloon dilation (PBBD) of benign hepaticojejunostomy strictures and evaluate the necessity of repeated PBBD in this setting. MATERIALS AND METHODS PBBD was performed after traversing hepaticojejunostomy strictures in 89 patients (40 male, 49 female; age range, 19-84(More)
To assess the role of multidetector computed tomography (MDCT) with multiplanar reconstruction (MPR) and virtual gastroscopy (VG) for detection and differentiation of gastric subepithelial masses (SEMs) by comparison with endoscopic ultrasonography (EUS). Forty-one patients with a suspected SEM were evaluated using EUS and MDCT. MDCT findings were analyzed(More)
Situs inversus totalis is a rare condition that may not cause symptoms and often occurs concomitantly with other congenital anomalies. Special attention must be given to these patients when invasive interventions are required. There are only a few reports concerning percutaneous transhepatic biliary interventions in situs inversus totalis, but technical(More)
The median arcuate ligament is a tendinous arch joining the two medial borders of the diaphragm crura together. In 13-50% of asymptomatic subjects it is responsible for significant angiographic celiac trunk compression. The significance of median arcuate ligament-associated celiac artery compression has been a source of some controversy in the past(More)
