Paraplegia developed in a 70-year-old man after resection of a ruptured abdominal aortic aneurysm during which aortic occlusion time was 45 minutes. Between one and three months postoperatively, he progressively recovered motor function to the point where he could walk unaided. Only four patients have previously been reported to recover from paraplegia produced in this manner. A review of the literature on the anatomy of the arterial supply to the spinal cord indicates the importance of the anterior spinal artery and the artery of Adamkiewicz (arteria magna radicularis). Paraplegia is more common in patients with hypotension and when backbleeding from the lumbar arteries has been poor.

Spinal cord evoked potentials elicited by direct stimulation of the spinal cord were monitored in 21 patients during thoracic or thoraco-abdominal aortic aneurysm surgery. Flexible catheter-type electrodes were used for both stimulating and recording. The basic pattern of the spinal cord evoked potential consisted of an initial spike and a subsequent polyphasic component. The earliest and most frequent alterations after cross-clamping of the aorta were changes in the configuration or amplitude of the polyphasic component. In 13 patients who exhibited no change except minor alterations of the polyphasic component during the initial test clamping for 15 or 20 min, subsequent graft replacements were safely performed without reimplantation of intercostal vessels. In 2 patients who had sudden cardiac arrests, the evoked potential completely disappeared. The polyphasic component disappeared first, followed by the initial spike. Another patient developed acute loss of the potential after the aneurysm was incised, presumably due to distal aortic hypoperfusion. In this case, prolonged distal hypotension resulted in flaccid paraplegia. Intraoperative monitoring of the spinal cord evoked potential is a useful method for the early detection of spinal cord ischemia during surgery requiring aortic occlusion.

Aneurysms of the abdominal aorta have been recognised as a cause of back pain and vertebral erosion. However back pain and paraplegia are uncommon, presenting complaints in patients with aortic aneurysms. A case of acute rupture of an abdominal aortic aneurysm is presented mimicking the symptoms of a discus hernia syndrome and paraplegia.

Between January 1, 1980, and June 30, 1989, 9 patients (6 males and 3 females) developed ischemic injury to the spinal cord or lumbosacral plexus following 3,320 operations on the abdominal aorta (0.3%). The incidence of this complication was 0.1% (2 of 1,901) after elective and 1.4% (3 of 210) after emergency abdominal aortic aneurysm repair, and 0.3% (4 of 1,209) after repair for occlusive disease. Three of the latter had prior clinical evidence of distal embolization. Eight grafts were bifurcated (aorto-iliac:four, aorto-femoral: three, aorto-ilio-femoral:one). One patient underwent extra-anatomic revascularization. Only two patients had supraceliac aortic cross-clamping and one patient underwent exclusion of both internal iliac arteries. Four patients had hypotension. Early mortality was 22% (two of nine). Severe perioperative complications, mostly due to associated visceral and somatic ischemia and sepsis, were present in seven of the nine patients. The extent and type of the neurologic injury correlated with long-term outcome. Patients with ischemic injury of the lumbosacral roots or plexus had better recovery. Attention to the pelvic circulation and the collateral blood supply is important. Use of gentle technique to prevent embolization, avoidance of hypotension and prolonged supraceliac cross-clamping, revascularization of at least one internal iliac artery, and the use of heparin may decrease but not eliminate paraplegia. Once this unexpected complication occurs, careful neurologic evaluation should be done to localize the lesion and aid prognosis.

Between January 1987, and December 1988, 14 cases of descending thoracic or thoraco-abdominal aortic aneurysm underwent operation using a prosthetic graft replacement. In order to avoid hypoperfusion to distal organs and proximal hypertension during aortic cross-clamping, two different adjuncts were used and the effectiveness of those methods were compared according to the results of surgery. Seven patients were treated with a temporary shunt of heparin-bonded tube from the left axillary artery to left femoral artery, or else Dacron vascular prosthesis from right axillary artery to right femoral artery (Group I). In Group II (seven patients), left heart bypass was performed, using a centrifugal pump from the left atrium to the left femoral artery with minimal heparinization. In Group I, there were two hospital deaths, due to respiratory and hepatic failure respectively, and paraplegia has occurred in one case. In Group II, there was no death during a post-operative observation period of 5-15 months, and there was no case of paraplegia. We think that temporary left heart bypass with a centrifugal pump seems to be the most useful method today for graft replacement of the descending thoracic or thoraco-abdominal aorta.

A 65-year-old man with a previously undiagnosed abdominal aortic aneurysm presented with acute paraplegia. Elective resection of the aneurysm was undertaken one week later. Following this, almost complete neurological recovery was regained by 11 months.

The authors report seven cases of abdominal aortic aneurysm rupturing into the inferior vena cava system. Symptoms were protean, but included local clinical manifestations and general findings due to the high-flow arteriovenous fistula. In spite of different types of clinical presentation, the correct preoperative diagnosis was made when a continuous bruit with systolic accentuation was heard over the abdomen. Venous repair consisted of simple closure of the fistula from within the aneurysm in six cases. In one case, treatment required ligation of the right common iliac vein. There were two cases of paraplegia, one before and one after the operation. Two of the seven patients died.

We experienced 4 cases of thoracoabdominal and suprarenal abdominal aortic aneurysm in the last 6 months. There were 3 males and 1 female ranging in age from 43 to 66 years, 2 with an etiology of aortitis syndrome, 1 with non-specific inflammation and 1 with atherosclerosis. In all cases the modified Hardy procedure was employed. A 18 to 22mm X 9 to 11mm bifurcation, double velour woven dacron graft was sutured from the side of the lower descending thoracic aorta to the side of both common iliac arteries. Grafts of the same kind as above 6 to 7mm in size were attached from the main graft to major visceral arteries by end-to-end or end-to-side anastomosis. A permanent aortic-excluding clamp was attached to the normal aorta just proximal to the aneurysm. Another clamp, or double ligature with silk, was placed on the lower abdominal aorta or both common iliac arteries distal to the aneurysm. No renal and spinal preservation of any kind was employed, but renal failure and paraplegia were not recognized in any of the cases. One patient died 2 days and another 21 days after the operation due to uncontrollable bleeding and multiple organ failure. The other two are doing well.

Well-known complications of abdominal aortic aneurysm surgery include haemorrhage, arterial occlusion, infection and aortoduodenal fistula. Less well known is the occurrence of paraplegia. At present there is no estimate of its incidence, and only isolated cases have been reported. We report 2 cases of paraplegia following elective aortic surgery and 2 others following acute occlusion of the abdominal aorta.

Abdominal aortic aneurysm is a condition affecting nearly 4% of the elderly population. It has a potential for producing a wide range of symptoms, including abdominal pain and back pain. The latter is particularly difficult to interpret in patients with chronic rheumatological conditions, and delayed diagnosis may be associated with a poor outcome. We present a patient with rheumatoid arthritis and chronic low back pain, who developed bilateral leg weakness and hesitancy of micturition, due to an abdominal aortic aneurysm invading the spine.
