Secondary aortoesophageal fistula (AEF) is a rare but catastrophic complication that occurs after thoracic aortic reconstruction. Recently endoluminal stent grafts have been used in selected patients with a thoracic aortic aneurysm, dissection, or traumatic aortic transection. A 24-year-old woman had massive upper gastrointestinal tract bleeding 15 months after endoluminal stent ...

Paraplegia or paraparesis secondary to spinal cord ischemia is an extremely rare complication after elective repair of abdominal aortic aneurysm. We report delayed paraparesis after endovascular abdominal aortic aneurysm repair in which one hypogastric artery was unintentionally occluded due to atheroembolism. A spinal catheter was immediately inserted after onset of ...

Salmonella aortic aneurysms occasionally affect adjoining organs. This study reports on 2 elderly men with fatal cases of Salmonella enteritidis involving adjacent organs: aortobronchial fistula from a thoracic aneurysm, and renal involvement from an infrarenal aneurysm. The hope of averting a tragic outcome lies in prompt clinical and radiological recognition ...

We describe the use of rib-cross thoracotomy and costal coaptation pins made with bioabsorbable poly-L-lactide for rib approximation. This thoracotomy provided an excellent intraoperative exposure of the entire descending aorta and thoracoabdominal aorta in patients with extended thoracoabdominal aortic aneurysm without increase in postoperative morbidity.

Thoracoabdominal aneurysm repair continues to be associated with a significant risk of operative complications, many of which are related to the prolonged period of aortic cross clamping inherent in the procedure. A variety of adjuvant techniques have been used in attempts to decrease morbidity, including atriofemoral extracorporal bypass, subarachnoid drainage, ...

Spinal cord ischemia is a major cause of complications after operative and endovascular treatment of descending thoracic or thoracoabdominal aortic aneurysms. Prior revascularization of the intercostal artery (IA) giving rise to the artery of Adamkiewicz (AA) using an artery of the thoracic wall would preserve circulation in the AA and ...

Chronic traumatic aneurysm of the thoracic aorta is an unusual occurrence. Open-chest surgery for repair of chronic traumatic aneurysms results in mortality rate of 5-18%, and a morbidity rate of 11-50% also. The evolution of endovascular technology offers the promise of a new, less invasive method to achieve aneurysm exclusion. ...
