Relationship between body figure and stump length in cyanoacrylate closure of varicose veins.

Background: Recurrence of incompetent saphenous veins after treatment is associated with remnant reflux to the branches close to the saphenofemoral or saphenopopliteal junctions, which originate from the residual patent stump after saphenous vein treatment. This study aimed to determine the factors affecting residual stump length after cyanoacrylate closure.

Methods: This retrospective study used prospectively collected data of patients who underwent cyanoacrylate closure.

Systemic single administration of anti-inflammatory microRNA 146a-5p loaded in polymeric nanomedicines with active targetability attenuates neointimal hyperplasia by controlling inflammation in injured arteries in a rat model.

Neointimal hyperplasia (NIH) after revascularization is a key unsolved clinical problem. Various studies have shown that attenuation of the acute inflammatory response on the vascular wall can prevent NIH. MicroRNA146a-5p (miR146a-5p) has been reported to show anti-inflammatory effects by inhibiting the NF-κB pathway, a well-known key player of inflammation of the vascular wall.

Successful endovascular repair of iliac artery aneurysms with unsuitable anatomy by combining unibody bifurcated endograft and iliac branch systems to preserve hypogastric artery blood flow: a report of two cases.

Background: To overcome the anatomical limitation of a narrow aorta and short length from the renal artery to the terminal aorta, unibody endograft AFX2 and iliac branch endoprosthesis (IBE) can be combined.

Case Presentation: Case 1: The first patient was an 89-year-old woman who had a right saccular common iliac artery (CIA) aneurysm (38 mm); the abdominal aorta was not aneurysmal (diameter, 19 mm). The right CIA's origin was 10 mm in diameter.

Endovascular Stent Graft Placement and Coil Embolization for Splenic Artery Aneurysm with an Anatomical Variant.

A 62-year-old woman with abdominal pain was diagnosed with a splenic artery aneurysm (SAA) and an anatomical variant in the splenic artery (SA) arising from the superior mesenteric artery (SMA) as its first branch. To treat the SAA, the draining artery and a small branch of the SAA were embolized, and then small-diameter stent grafts were deployed from SMA orifice, covering the aberrant origin of the SA and preserving the second branch of SMA. Intraoperative angiography confirmed successful exclusion of the SAA without endoleak or arterial dissection.

Clinical Impact of Stent Graft Thrombosis in Femoropopliteal Arterial Lesions.

Objectives: This study sought to elucidate the clinical impact and prognosis of stent graft (SG) thrombosis.

Background: The VIABAHN SG offers a favorable outcome in long peripheral artery occlusive disease (PAOD) lesions in the femoropopliteal artery. One concern after SG deployment is the incidence of stent thrombosis and consequent acute limb ischemia (ALI).
