Abstract

A 53-yearold man with a dissecting aneurysm of Stanford's type-B or Crawford's type I measuring 8.5 cm in diameter underwent replacement of the distal descending aorta and the thoracic aorta using techniques for spinal cord protection involving deep hypothermia at 17 degrees C and lasting 38 minutes with total absence of circulation. A subarachnoid catheter was inserted at the lumbar level to monitor spinal fluid pressure as well as to provide drainage if pressure exceeded 10 mm Hg. During surgery 60 ml was drained, followed by 95 ml after surgery on the same day and 325, 262 and 169 ml on the following three days. No signs of neurological deficit were observed during the postoperative period. Clinical course was good until hypovolemic shock developed 27 days after the operation due to upper digestive tract bleeding caused by two duodenal ulcers that perforated the gastroduodenal artery. Emergency antrectomy and vagotomy were performed. The patient died from multiple organ failure. Spinal cord injury continues to be one of the most feared complications after excision of thoracic and thoracoabdominal aorta aneurysm. Currently, various ways of protecting the spinal cord are practiced, including drainage of cerebrospinal fluid, pa...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.

CSF & Lymphatic System

This feed focuses on Cerebral Spinal Fluid (CSF) and the lymphatic system. Discover the latest papers using imaging techniques to track CSF outflow into the lymphatic system in animal models.
