Surgical transluminal femoropopliteal angioplasty: multivariate analysis outcome.

PURPOSE: The purpose of this study was to determine the efficacy of femoropopliteal transluminal angioplasty performed in the operating room by vascular surgeons and the factors that might influence outcome. METHODS: The clinical, biologic, and angiographic, findings of 103 consecutive transluminal angioplasties performed in the operating suite in 95 patients for occlusive disease of the femoral or popliteal arteries were analyzed. With each variable, patency was compared according to the log rank test, and a Cox multivariate analysis was applied to the statistically significant variables. RESULTS: Local, general, and vascular complications occurred in 2.8%, 0.9%, and 2.8% of cases, respectively. The cumulative patency rate was 77.9% +/- 3.9% at 1 month, 59.8% +/- 5.35% at 1 year, and 51.3% +/- 6.15% at 2 years, including early failures (20.7%). Of 11 preoperative factors studied, only the stenotic or occlusive character and the length of the lesion were shown to be statistically significant (p < 0.001 and p < 0.01, respectively). The constructed mathematic Cox proportional hazards regression model allowed definition of the probability of success according to four groups, based on angiographic findings. At 2 years the probability of success was 80% in patients with stenosis less than 2 cm long, 62% in patients with stenosis greater than 2 cm, 42% in patients with occlusion less than 2 cm long, and 20% in patients with occlusion greater than 2 cm long. CONCLUSION: Transluminal femoropopliteal angioplasty may be performed safely by vascular surgeons in the operating room. Based on this model, proper selection of patients who might best benefit from transluminal angioplasty for femoropopliteal disease may be made.

[Bilateral stenosis of the renal arteries: transaortic endarterectomy].

Transaortic renal endarterectomy with infra-renal aortic prosthetic graft may be used to treat combined aortic and renal atherosclerosis. We present herein the technics we used in seven patients, which represented 0.4% of our aortic revascularizations and 15% of our combined aortic and renal revascularizations. All these patients were hypertensive and four had a mild preoperative renal insufficiency. Post-operatively there were no death and the morbidity rate was 12%. Morphological assessment showed no renal or limb graft occlusion. During the follow-up there were three deaths, one limb graft occluded. All renal arteries remained patent with improvement of hypertension in 70% and stabilisation of the renal function in all. In carefully selected cases, transaortic renal endarterectomy is a safe and efficient method of treatment of combined aortic and renal atherosclerotic disease.

[Influence of coronary disease on the results of carotid surgery].

The object of this retrospective (case-control) study of 513 carotid artery operations in 471 patients was to evaluate whether the presence of coronary artery disease at the time the decision to operate was taken, influence the prognosis of patients operated upon for stenosis of a carotid artery. Three groups were constituted and compared; no coronary artery disease (NC), stable coronary artery disease (CS) and unstable coronary artery disease (CI). Operative mortality was 1% (NC), 5% (CS) and 9% (CI) respectively (p < 0.001). The rate of neurologic deficits was 1.3% (NC), 2.4% (CS) and 3.1% (CI), and the 5 year actuarial survival rate 83% (NC), 78% (CS) and 63% (CI) (p = 0.040 by the Log-Rank test). Premature deaths were due to cardiac and neurologic causes. In the patients with coronary disease, local and regional anesthesia was followed by 0% mortality whereas the rate was 3% (CS) and 13% (CI) (p < 0.001) after general anesthesia. The cause of delayed death was determined accurately in 50% of cases; it was cardiac in 25% (NC) and 70% in patients with coronary disease. Results of the present study confirm that the presence of coronary disease has an adverse effect on the immediate and long term prognosis for patients undergoing coronary artery surgery, and demonstrate that the operative risk can be significantly reduced by the use of local and regional anesthesia. Long term close cardiology surveillance is justified, particularly if signs of coronary disease are noted perioperatively.

[Congenital stenosis of the esophagus due to tracheobronchial heterotopia. Review of the literature. Apropos of a case].

A case of congenital esophageal stenosis due to tracheobronchial remnants is reported. This is a very rare condition. Only 46 previous cases have been reported in the French and English literature. The cause is thought to be esophageal sequestration of a tracheobronchial anlage before embryologic separation. Esophageal atresia is frequently associated with this rare abnormality. Symptoms generally appear early in infancy, but are sometimes very discrete and diagnosis can be made later in infancy of exceptionally in adulthood. When there is no evidence of gastric reflux and caustic ingestion, symptoms of esophageal obstruction with date back to infancy or childhood are often the only sign suggestive of congenital stenosis. However, the diagnosis can only be established by microscopic examination of the entire esophageal wall, as endoscopic biopsy will not show the heterotopic tissue lying deep under the normal mucosa. The presence of tracheobronchial remnants in the esophageal wall explains why treatment by dilatation is unsatisfactory or impossible. Definitive treatment involves excision of the stenotic segment.
