Acute traumatic rupture of the thoracic aorta: place of delayed surgical repair.

Acute traumatic rupture of the thoracic aorta (ATRTA) is considered as an emergency which requires immediate surgery. However surgical mortality is high with an average of 20% in the literature. Twenty seven patients were observed from 1973 to 1986. Three patients were not operated upon (Group I), twenty patients had immediate surgery (Group II) with 60% mortality, four patients underwent delayed surgery (Group III) with 25% mortality. Analysis of cause of death show that associated lesions were present in 72% of pts who did not survive and in only 37% among survivors. Associated lesions may be lethal initially (e.g. brain trauma) or they may be aggravated by the thoracic procedure. Complications from associated lesions may also compromise the outcome. It is well known that the majority of deaths from ATRTA occur within 24 hours. Immediate repair of the aortic lesion should be the rule when aortic rupture is isolated or associated with moderate injuries. It may be however that in some cases with severe and multiple associated lesions who survive the initial aortic injury, delayed repair of ATRTA could be considered.

Treatment of lymphorrhea with exposed or infected vascular prosthetic grafts in the groin using sartorius myoplasty.

Thirteen myoplasties using the sartorius muscle were performed on 12 patients from 1980 to 1985 for "healing problems" in the groin with subjacent synthetic grafts. Persistant aseptic lymphorrhea was the indication for 4 patients. In 3 other cases, bacterial cultures from the wound were positive. In 2 other patients there was clinical evidence of sepsis with purulent discharge from the wound and an exposed graft. In 3 cases myoplasty was used as a preventive measure after reoperation on patients in poor general condition. Follow-up extends from 3 to 54 months. There was only one recurrence observed at 19 months which was successfully treated by segmental resection of the infected graft and insertion of a new prosthesis through the obturator canal. No recurrence was observed among the other patients as judged by clinical observation and biological tests for inflammation, echotomography, CT scan and indium scintigraphy. The treatment of choice for an infected prosthesis should be removal of the graft and extra-anatomic bypass in the majority of cases. However in some situations, excision of the wound and myoplasty using the sartorius muscle may be of some value and needs further evaluation.

Chronic traumatic aneurysms of the descending thoracic aorta (19 cases).

From 1973 through 1983, 19 cases of chronic traumatic aneurysms (CTA) were observed. Initial trauma was well documented in every case. Patients mean age at time of trauma was 22; mean age at time of surgery was 34. Sixty per cent of patients had no apparent thoracic injury at time of trauma. Ninety-five per cent had associated injuries. Ten/nineteen were asymptomatic. Eighteen were operated on. Rupture was complete in 11, partial in 7. One of the partial ruptures was a simple scar on the aorta. Eighteen were located at the site of the aortic isthmus, one was at level T8-T9. Seventeen had a prosthetic dacron graft sutured from inside the aneurysm. The case where a simple scar was found had a dacron wrapping. Spinal cord protection was used in all cases except in one who was already paraplegic preoperatively. Various shunts were used in 12 cases; 1 patient in the by-pass group had paraplegia. CTA is not a benign disease and all cases, even asymptomatic, should be operated on with a very low risk of mortality (0/18). Occurrence of paraplegia still remains a possible complication although the risk of spinal cord ischemia seems lower than in arteriosclerotic dissecting aneurysms. We favour the "old" technique of temporary dacron shunt graft in CTA for simplicity and easy assessment of function ot the shunt.

The place of cardiac denervation in the surgical treatment of Prinzmetal variant angina.

Coronary artery spasm has been described as occurring frequently in Prinzmetal variant angina. The relatively poorer results obtained after aorto-coronary by pass grafting carried out in patients with Prinzmetal angina may be due to recurrence of spasm despite the grafts. Accordingly it has been our recent policy since February 1973 to carry out cardiac denervation in all patients with Prinzmetal variant angina. The patients fall into two groups depending on the presence or absence of organic disease in the coronary vessel. The technique of cardiac denervation (plexectomy) as described by Arnulf is fully described and the early and late results of this procedure in the two groups are documented and discussed.
