correction) to type IV (graft porosity, rarely seen with current
devices). In the study, the occurrence of early endoleaks was low and
included 18 (5.5%) type I, four (1.2%) type II, and two (0.6%) type III
-- Paraplegia: Thoracic ELG repair can cause decreased blood supply to the
spinal cord, leading to paraplegia. In this study, paraplegia occurred
in five (1.5%) patients and paresis (slight or partial paralysis) in
three (0.9%); two of the latter improved and one resolved completely
prior to discharge. Paraplegia remains low as a complication and
expectedly increases with difficult anatomy, specific conditions or
open surgical approach. Associated paraplegia with open repair is
estimated at 4%.
-- Mortality: At short-term follow-up, 18 (5.5%) deaths related to the
underlying thoracic aortic pathology occurred within the first thirty
days of the procedure, including three intraoperative deaths. Late
mortality was 9.6% with 31 deaths unrelated to the procedure or
-- Complications: The overall complication rate was 22.7%, 14.2% (46) in
elective cases and 8.5% (28) in non-elective cases. The vast majority
of these were minor and easily managed with satisfactory outcomes.
Thoracic Aortic Aneurysms and Related Conditions
The aorta is the largest artery in the human body which carries blood
away from the heart, with the thoracic aorta being the portion of the aorta
coursing through the chest. When a weak area of the thoracic aorta expands
or bulges like a balloon, it is called a thoracic aortic aneurysm (TAA).
TAAs are often caused by atherosclerosis, or hardening and weakening of the
arteries. An aortic dissection, which is often associated with high blood
pressure, occurs when blood flow forces apart and weakens the aortic wall
layers, often leading to ane
