Abstract

This study evaluated the effects of a combined imaging protocol using low-frequency pulsed fluoroscopy, fusion imaging, and low-concentration iodine contrast for endovascular aneurysm repair (EVAR) of aortic aneurysms of varying complexity. The study retrospectively reviewed the data of 103 patients treated between May 2013 and November 2014 with the combined imaging protocol (group A) with low-dose fluoroscopy at 3.75 frames/s, fusion imaging, and iodine contrast of 140 mg iodine/mL. A control group (group B) consisted of 123 consecutive patients who underwent EVAR before the combined imaging protocol was introduced by matching the type of procedure. In group B, low-dose 7.5 frames/s fluoroscopy, no fusion imaging, and 200 mg iodine/mL contrast were used. All patients were reviewed for preoperative, intraoperative, and postoperative variables, with emphasis on intraoperative radiation (dose area product) and iodine exposure, fluoroscopy, and operation times, as well as technical success. Values are presented as median and interquartile range (IQR) when not stated otherwise. Group A included 22 infrarenal EVARs, 17 iliac branch devices, 10 thoracic endovascular aortic repairs, 21 fenestrated EVARs, and 33 thoracoabdominal branc...Continue Reading

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.

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.

Aneurysm

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