We analysed pooled data from two clinical trials to assess the diagnostic accuracy and safety of meglumine gadoterate (Gd-DOTA)-enhanced MR angiography (MRA) relative to those of non-enhanced time-of-flight (TOF) MRA for non-coronary arterial disease. Both techniques were compared with X-ray angiography as the gold standard. Patients were of both sexes, ...

Acute basilar artery occlusion (BAO) is a condition producing high rates of morbidity and mortality. Intravenous thrombolysis or intra-arterial thrombolysis are therapeutic options; however, the clinical outcomes remain poor. The purpose of the present study was to evaluate feasibility, safety, and efficacy of emergency stent placement following intra-arterial thrombolysis for ...

Anomalous right coronary artery arising from the left sinus (ARCA) is a known cause of sudden cardiac death, particularly in young athletes. Surgery is recommended for all adult patients who are symptomatic or who have evidence of exercise-induced myocardial ischemia. Surgical options include coronary artery bypass grafting (CABG) and anatomic ...

BACKGROUND AND PURPOSE: Unruptured cerebral aneurysms are currently considered a contraindication to intravenous tissue-type plasminogen activator for acute ischemic stroke. This is due to a theoretical increase in the risk of hemorrhage from aneurysm rupture, although it is unknown whether this risk is a significant one. We sought to determine ...

Patients with peripheral arterial disease (PAD) are at increased risk for all-cause mortality, cardiovascular mortality, and mortality from coronary artery disease. Smoking should be stopped and hypertension, dyslipidemia, diabetes mellitus, and hypothyroidism treated. Statins decrease the incidence of intermittent claudication and improve exercise duration until the onset of intermittent claudication ...

AIM: Horseshoe kidney is the most common congenital kidney anomaly, occurring in 0.15-0.25% of all newborns. A medial fusion of the kidneys, mostly anteriorly to the aorta, is the main characteristic of this anomaly. The co-existence of abdominal aortic aneurysm (AAA) and horseshoe kidney is rare, occurring only in 0.12% ...

Pancreaticoduodenectomy is the treatment of choice for periampullary and pancreatic head tumors. In case of hepatic artery abnormalities, early pancreatic transection during pancreaticoduodenectomy may prove inappropriate. Early retroportal lamina dissection improves exposure of the superior mesenteric vessels and anatomic variants of the hepatic artery, where safeguarding is mandatory. We describe ...
