Abstract

To investigate the safety and efficacy of the parallel covered stents technique in the treatment of anatomically challenging aortic aneurysms, pseudoaneurysms, and dissections. Data were retrospectively collected from 16 patients with abdominal aortic diseases who were treated with parallel covered stents (Gore Excluder, n = 14; Medtronic Endurant, n = 2) between January 2016 and July 2018. Patients were treated with this technique if they were unsuitable for either open repair or standard endovascular aortic repair with bifurcated stents. Such unfavorable anatomy included narrow aortic necks (≤18 mm), small vascular access (occluded or ≤6.0 mm), or compressed aortic lumens (≤18 mm). All patients were male, with a mean age of 64.7 ± 13.3 years. For true aneurysms (n = 4) and pseudoaneurysms (n = 4), the mean diameter and length of the proximal necks were 17.5 ± 2.6 mm (range, 14-21 mm) and 51.0 ± 12.5 mm (range, 39-75 mm), respectively. The minimal diameter of true lumen in cases with aortic dissection and penetrating ulcers (n = 8) was 14.8 ± 3.1 mm. Small or occluded femoral access was found in 3 patients. Technical success was 100%. Minor type I endoleaks, which were seen on completion angiography in 5 patients, had all reso...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
