Heart failure necessitating left ventricular assist device (LVAD) support can lead to kidney failure requiring dialysis. Some of these patients may require long-term hemodialysis (HD). Optimal vascular access for a patient on long-term HD therapy with an LVAD remains a complex issue. The majority of LVADs are of the continuous-flow type, and it has been theorized that native arteriovenous fistula maturation may be impaired in a setting of decreased pulsatile arterial flow. We describe a case of successful creation and use of an arteriovenous fistula in an HD-dependent patient with a continuous-flow LVAD.

Purpose: A persistent trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Persistent trigeminal artery variants (PTAVs) terminate in the cerebellar arteries without connecting to the basilar artery; of these, the anterior inferior cerebellar artery (AICA) is the most common. AICA duplication is frequently observed.

Background And Objectives: There is no dedicated occlusive device for closing coronary artery fistulas (CAFs), and specific efficacy and safety data of various off-label occlusive devices for CAFs closure are scarce.
Methods: Patients undergoing transcatheter closure of CAFs from January 2011 to December 2022 were included in the single-center retrospective study. The study population was divided into 2 groups: coils group (n=35) and patent ductus arteriosus (PDA) occluders group (n=66).

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

A superior mesenteric arteriovenous fistula (SMAVF) following gastrointestinal surgery represents a rare vascular complication. Enhanced computed tomography with 3-dimensional reconstruction proves to be the most efficacious modality for detecting this uncommon entity. Superior mesenteric angiography becomes imperative to accurately delineate the location and extent of mesenteric vessel involvement, which is essential for devising an optimal treatment strategy.
