Hepatic arterial loop with accessory right hepatic artery aneurysm with celiac atresia: endovascular therapy with a stent and detachable coils.

The present report describes an unusual case of an aneurysm of a right hepatic artery (RHA) branching from the superior mesenteric artery; the accessory RHA was looped to the left hepatic artery arising from the celiac axis (CA) and was associated with congenital atresia of the CA. The accessory RHA aneurysm was treated with the placement of a bare stent and detachable coils through the mesh of the stent. Complete and prompt exclusion of the aneurysm was achieved with blood flow preservation in the parent artery at midterm follow-up.

Bleeding duodenal: varices treatment by TIPS and transcatheter embolization.

We describe our clinical experience in 4 patients with portal hypertension who presented with bleeding mesenteric varices originating from the superior mesenteric vein with retrograde filling of collaterals draining into the inferior vena cava. The clinical presentation, imaging findings, and potential therapeutic management are discussed.

Malignant duodenal obstructions: palliative treatment using self-expandable nitinol stents.

Purpose: To assess the efficacy of fluoroscopic per oral placement of self-expandable nitinol stents in the palliative treatment of malignant duodenal obstructions.

Materials And Methods: Under fluoroscopic guidance, 82 patients (56 male and 26 female; mean age, 62.3 y) with malignant duodenal obstructions were treated with per oral placement of four types of self-expandable nitinol stents.

A modified technique to minimize filter tilting during deployment of the Günther Tulip filter: in vitro study.

With an in vitro model of the inferior vena cava, it was demonstrated that slight tension on the introducer during quick release of the jugular Günther Tulip filter led to less tilting of the filter compared with the technique recommended by the manufacturer. This technique may be useful to minimize significant filter tilting that may be associated with decreased filtration efficiency, and difficulty or impossibility of future filter retrieval.

Bilateral adventitial cystic disease of the popliteal artery: a case report.

Adventitial cystic disease (ACD) of the popliteal artery is an uncommon vascular condition of unknown etiology. In the present case report, we describe a case of bilateral ACD of the popliteal artery in a 58-year-old male. To the best of our knowledge, this is the first case of bilateral ACD of the popliteal artery reported in the literature.
