Abstract

Spinal cord ischemia (SCI) is a feared complication following thoracic endovascular aortic aneurysm repair (TEVAR). European Society for Vascular Surgery guidelines suggest lumbar drainage of cerebrospinal fluid (CSF) in high-risk patients. The institutional protocol proposes as indications for CSF drainage: coverage of Adamkiewicz artery origin (T9-T12), aortic length of coverage >15 cm, compromise of collateral arteries (left subclavian or internal iliac occlusion) and symptomatic SCI. The aim of this study is to demonstrate CSF drainage efficacy and safety in the prevention or treatment of TEVAR-related SCI. Patients submitted to TEVAR with perioperative CSF drainage between May 2015 and April 2017 at our hospital were prospectively included. The primary outcome consisted of prevention or regression of neurological symptoms (efficacy). Other complications were recorded as secondary outcomes (safety). Nine patients, aged between 63 and 75 years, were included. Eight surgeries were elective and one was emergent. Eight lumbar catheters were placed before surgery and one in the postoperative period due to SCI symptomatology that reverted after CSF drainage. Of those placed preoperatively, 2 developed postoperative SCI symptoms t...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.
