After Endurant stent grafting, the incidence of limb occlusion was low. Classifying patients as high risk vs low risk according to the algorithm used in this study may help define specific strategies to prevent limb occlusion and improve the overall results of endovascular aneurysm repair using the latest generation of stent grafts.

Octogenarians are more difficult to treat by EVAR than younger patients due to poorer anatomic suitability and a higher incidence of complications. Recovery of QOL in octogenarians takes longer (>12 months) than expected.

ORIGINAL ARTICLE PURPOSE We aimed to compare the effect of using different embolic agents such as gelfoam and polyvinyl alcohol (PVA) on survival, tumor response, and complications in transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) patients. MATERIALS AND METHODSWe retrospectively reviewed the medical records of 38 inoperable HCC patients who underwent TACE between August 1998 and April 2007. A total of 50 TACE sessions were performed using PVA (n=18) or gelfoam particles (n=20), following the application of 60 mg doxorubicin with 10-20 mL lipiodol emulsion. The PVA and gelfoam groups were compared based on clinical, laboratory, and demographic variables. Survival rates were calculated starting from the first TACE session using the Kaplan-Meier analysis. RESULTSThere was no significant difference between the survival rates of PVA and gelfoam groups (P = 0.235). Overall survival rates at 12, 24, 36, 48, and 60 months were 55%, 36%, 15%, 7%, and 5%, respectively. Tumor response, age, lipiodol accumulation type, number of HCC foci, complications, and serum alpha-fetoprotein level were significant factors for survival in all patients. CONCLUSIONUse of gelfoam or PVA as the embolic agent did not have a significant impact on survival. Complete tumor response, intensive lipiodol accumulation in tumor, older age (>60 years), fewer (≤3) HCC foci, and low serum alpha-fetoprotein level (≤400 ng/mL) were found to improve cumulative survival significantly.

Compression of the left renal vein between the aorta and the superior mesenteric artery, known as the nutcracker phenomenon, may cause gross or microscopic hematuria, pain in the flank, proteinuria, or a combination of these symptoms. We report the case of a hematuric adolescent diagnosed with a high index of suspicion by noninvasive Doppler sonography using the diagnostic indices of Doppler sonography established for adults with hematuria. Compression of the patient's left renal vein at the aortomesenteric portion and dilatation at the hilar portion were visualized by magnetic resonance angiography, which verified the diagnosis.
