Three-dimensional ultrasound volume and conventional ultrasound diameter changes are equally good markers of endoleak in follow-up after endovascular aneurysm repair.

Introduction: The main disadvantages of computed tomography angiography (CTA) in follow-up after endovascular aneurysm repair are the risks of contrast-induced renal impairment and radiation-induced cancer. Three-dimensional ultrasound is a new technique for volume estimation of the aneurysm sac. Some studies have reported promising results.

Contrast-enhanced ultrasound detects type II endoleaks during follow-up for endovascular aneurysm repair.

Objective: Repeated computed tomography angiography (CTA) can be used during follow-up visits for endovascular aneurysm repair (EVAR) but leads to accumulated radiation exposure and may cause renal impairment. Therefore, the use of contrast-enhanced ultrasound (CEUS) has increased, and its ability to detect endoleaks has been promising. The aim of this study was to investigate the diagnostic accuracy of CEUS vs CTA for endoleak detection during EVAR follow-up.

Spiral Vein Graft Technique for Popliteal Artery Aneurysms.

Introduction: In patients with popliteal artery aneurysm lacking a suitable vein for bypass, prosthetic graft, or endovascular stent graft are alternative treatment options. However, durability is limited. Construction of an autologous spiral vein graft has previously been used to replace infected aortic grafts and arteriovenous fistulas.
