Twenty-seven patients underwent surgical repair for nonpenetrating injuries of the thoracic aorta. Emergency operation was performed in 19 patients with acute aortic injury and there were 12 survivors. Left heart bypass (LHB), external shunts, and simple aortic cross-clamping were methods employed during repair. All operative deaths occurred in the left heart bypass group. Morbidity, hospital stay, operative time, and blood loss all were markedly less in patients repaired with an external shunt or simple cross-clamping. Systemic heparinization related adversely to mortality and morbidity. Eight patients had repair of chronic post-traumatic descending aortic aneurysms. One of these had previous repair elsewhere with paraplegia and subsequent mycotic aneurysm at the graft repair site. He presented to us with massive hemoptysis. Surgical correction in the chronic group was performed using either left heart bypass, external shunt, or simple aortic cross-clamp with graft interposition. The only death occurred in a patient repaired on left heart bypass.

During the last 10 years (1975-1985), a total of 18 cases of posttraumatic aneurysm at the level of the thoracic isthmus were operated on. Six of the 18 were women (19-71 years of age) and 12 were men (17-61 years of age). The mean age at the time of injury was, respectively, 22 and 25.8 years and, at the time of operation, 34.5 and 35.5 years. The patients were all involved in a motor vehicle accident, except for 2 (1 falling, 1 crushing). Thirty-nine percent of the patients had no apparent thoracic injury and 89% had associated injuries (bony fractures, craniofacial, visceral and abdominal). Eight of the 18 were asymptomatic at the time of operation, the others had various symptoms (pain, fever, dyspnea, cough, hoarseness, murmur, or hemoptysis). Enlargement of the aortic button was present in every case. Seventeen patients were operated on electively from 4 months to 50 years after the injury. Circumferential rupture was total in 9 patients and partial (2/3 to 9/10) in the others. Complete repair was done by either prosthetic Dacron tube (3), Dacron patch (2), or direct suture (12). Protection by femoro-femoral bypass was used in 3 and simple aortic cross-clamp was used in 14. Mean time of aortic cross-clamp was 36.9 minutes (range, 16-80 min). Among these 17 patients, there was no hospital mortality and no late death. One patient had regressive paraplegia. One patient was submitted to an emergency operation for an intrapulmonary rupture of an infected aneurysm and died in the operating room before completion of the repair.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1984 to 1993, 48 thoracoabdominal aortic aneurysm resections were performed. The patient age ranged from 21 to 79 years (mean: 65.5 years), and the extent of the aneurysms were as follows: type I (most of descending and upper abdominal), 17 cases; type II (most of descending and most of abdominal), 3 cases; type III (distal descending and upper abdominal), 20 cases; and type IV (most or the entire abdominal aorta), 8 cases. Ten patients presented with ruptured aneurysms, 1 with hemoptysis, 20 with pain, and 20 with no symptoms. Operation was performed using simple aortic cross-clamping in 18 patients, distal perfusion via Gott shunt in 6, and heparinless left-heart bypass (Biomedicus pump) in 24. Intercostal or lumbar vessels were reimplanted into the graft in 13 patients. Aortic cross-clamp time was 25 to 115 minutes (mean: 49.6 minutes). Four of 10 patients (40%) with ruptured aneurysms and 3 of 38 (8%) patients with non-ruptured aneurysms died. Serious complications included paraparesis in 2 patients (5%), renal failure requiring dialysis in 2 (5%), stroke in 1 (2%), bleeding in 5 (12%), intraoperative cardiac arrest in 3 (7%), sepsis in 1 (2%), prolonged ventilation (longer than 3 days) in 11 (27%), and wound dehiscence in 2 (5%). Thoracoabdominal aneurysm resection remains a challenging problem but can be performed with acceptable risk in selected patients. Distal heparinless perfusion without a heat exchanger may help reduce the risk of paraplegia and renal failure.

Between 1970 and December 1984, 28 patients with post-traumatic chronic aneurysm of the descending thoracic aorta were consecutively operated on in our Division of Cardiac Surgery. Ages ranged from 16 to 66 years (mean 38 years); 25 were male and three were female. In all cases, a history of a major deceleration injury was documented. The interval between trauma and operation ranged from 2 to 50 years (mean 11.4 +/- 7.8). Twenty-three (82.1%) were asymptomatic. Only one operation was performed on an urgent basis for recurrent episodes of hemoptysis. All patients underwent resection with prosthetic tubulargraft (25 cases) and patch-graft (3 cases) replacements. In all patients but one, left heart bypass was employed. No hospital deaths, late deaths, paraplegia or graft-related complications occurred. Considering the risk of late rupture and the young age of most of the patients, surgery in chronic post-traumatic aneurysms of the descending thoracic aorta is always indicated. We consider left heart bypass a safe technique in preventing renal and medullar ischemic injuries.

Open surgical management of acute rupture of the descending thoracic aorta (DTA) is associated with high mortality and morbidity. Endovascular stent-grafts (ESGs) could provide a less invasive treatment alternative to conventional open surgery. The purpose of this report detailing our experience using ESG for treatment of acute rupture of the DTA is to determine the indications for endovascular repair. From June 2000 to April 2005, 17 patients presenting rupture of the DTA were treated using commercially available ESGs at our institution. There were two women and 15 men, with a mean age of 41.9 +/- 20.5 years. The cause of aortic rupture was traumatic in 13 cases and nontraumatic in four. Treatment was undertaken immediately in 10 cases and delayed in seven (range 5-68 days, mean 23.5). In one patient, the proximal neck landing zone was prepared prior to endovascular repair. No patients died during the postoperative period. The technical success rate was 84%. One patient developed a proximal type 1 endoleak at the end of the procedure. Three complications, i.e., two iliac dissections and one femoral artery rupture, occurred during the procedure. No paraplegia was observed. Mean follow-up was 13.3 months (range 1-41). One patient treated for traumatic rupture was lost from follow-up 21 months after initial treatment. No procedure-related complication was observed in this traumatic rupture group. Control computed tomographic scan at 13 months following the procedure demonstrated no evidence of periprosthetic leak or false aneurysm. In the nontraumatic rupture group, two patients died of aortic rupture and one treated for aortobronchial fistula developed recurrent hemoptysis 23 months after initial treatment and required placement of two additional ESGs. The immediate outcome of covered stent-graft placement for management of acute aortic rupture of the DTA is good. However, long-term surveillance is mandatory, especially in patients treated for nontraumatic aortic rupture that is associated with a high late complication rate. Further study will be needed to determine the exact utility of endovascular therapy for aortic rupture: final treatment or bridge to conventional open-chest repair when the patient's condition has stabilized.

Bronchial artery embolization was attempted several times in a 74-year-old man undergoing right pneumonectomy for persistent hemoptysis. Paraplegia developed after surgery. Both thoracotomy for lung surgery and bronchial artery embolization have been reported to cause spinal cord ischemia. We analyze the possible mechanisms through which such ischemia may develop.

Complications related to the use of new diagnostic and therapeutic techniques are inherent to innovation in medicine. Appropriate consent should be obtained before subjecting patients to these techniques. In spite of doing this, when a complication does occur, one can easily relate to its devastating impact on the patient and his/her relatives. The toll that such events take on the treating physician also needs to be considered. The burden of conscience when a patient consents to such a procedure with implicit faith in the physician is immense. A case of irreversible paraplegia due to non-target embolisation of the anterior spinal artery in a young lady undergoing bronchial artery embolisation for hemoptysis is discussed. A feeling of "sadness and guilt" and a scientific analysis of the cause for the adverse event result in changing the protocol of the procedure leading to increased safety for future patients. Wide consultation with colleagues and help from institutional review boards are useful in assuring the treating physician about the justification of performing such procedures and help in coping should complications occur. The manner in which these events are managed, especially by medical teachers in teaching hospitals, is an important learning point for medical students and doctors in training. The need for appropriate open forums in institutions is emphasised, where such events are shared by physicians, resulting in unburdening themselves and potentially in education for all present.

An anomalous common trunk giving rise to bilateral intercostal arteries at multiple levels is exceedingly rare and its association with spinal filar AVF and low-lying cord has not been reported so far. Here, we report this uncommon anatomical variation in a 60-year-old male who presented with paraplegia and on imaging found to have low-lying spinal cord with filar AVF and venous congestive myelopathy and discuss its embryological basis and associated malformations. Although rare, interventional radiologists should be aware of this entity, as these trunks may be a major source of bleeding in patients with hemoptysis, and also may be involved in vital spinal cord supply.
