[Surgical treatment of telangiectasis]

The surgical treatment of telangiectasis synchronous to sclerotherapy is presented in this paper. Two female patients with extensive telangiectasis of the lower limbs comprise our report. They were considered typical cases for application of the proposed technique: abolishing venous reflux. The adjacent veins were resected through skin incisions of about 2 mm with crochet hooks, under local anesthesia, immobilized with adhesive tape. Sclerotherapy was performed simultaneously. The cosmetic result was excellent in both cases, with complete removal of the telangiectasis. This procedure should be considered the method of choice in the treatment of telangiectasis resulting from obvious venous reflux.

[Surgical treatment of infections involving arterial prosthesis in aorto-femoral position]

This article is to evaluate the results of surgical treatment of aorto-femoral graft infections. The records of 20 patients with aorto-femoral graft infections were reviewed. The patients were submitted mostly to a combination of surgical procedures. They were: a) conservative treatment; b) partial removal of the infected graft and c) total removal of the infected graft. The removal of the prosthesis, partial or total, was followed by a new arterial reconstruction in some patients. The final treatment was: total removal of the infected graft in 11 (55%) patients, total removal plus arterial reconstruction in six, partial removal in two and partial removal plus arterial reconstruction in one. The results of treatment were presented as the survival rate and the effective palliation (patient alive, lower limbs preserved and infection cured). The survival rates after one month, 12, 24, 36 and 48 months were respectively: 80%, 60%, 53%, 42% and 27%. The effective palliation rates after one month and after 48 months were respectively 50% and 27%. The highest effective palliation rate was obtained when the infected prosthesis was removed and a new arterial reconstruction performed. We conclude that the treatment of choice of aorto-femoral graft infections seems to be the total removal of the graft followed by new arterial reconstruction.

[Infection involving arterial prosthesis: clinical picture, etiology, and predisposing factors]

Thirty patients were operated for arterial reconstruction with synthetic grafts. They presented one of the following complications: 1) prosthesis exposed by a cutaneous fistula; 2) prosthesis in communication with a hollow viscus; 3) prosthesis involved by pus; 4) positive culture of a fragment of the prosthesis or of the surrounding secretion. The clinical manifestations were cutaneous fistula in 21 patients (70%), external bleeding in 14 (47%), exposition of the prosthesis in five (17%), anastomotic aneurysm in five (17%), and enteric fistula in four (13%). The infection became evident during the first postoperative year in half of the patients. The most important agents of infection were staphyilococci and Gram negative bacteria.

Rehabilitation after amputation for vascular disease: a follow-up study

Rehabilitation of one hundred and twenty eight patients with lower limb amputation performed for vascular disease from 1979 to 1987 was assessed. Arteriosclerotic occlusive disease was the most frequent cause of amputation (85.9%). Sixty seven patients (52.3%) were diabetic. Early and late results were analysed. For long-term follow-up evaluation, Univariate method of Kaplan-Meyer product limit was employed. Multifactorial analysis was used to assess factors influencing mortality. On immediate evaluation of rehabilitation with a prosthesis 85.2% of patients were successfully fitted. On long term evaluation 47.8% of below-knee and 22.1% of above-knee amputees were alive and using the prosthesis full time at five years of follow-up (p = 0.0026). Opposite limb preservation at five years was 69.5% for diabetics and 90.2% for non-diabetics, respectively (p = 0.0013). Survival rate at five years was 42.4% for diabetics, and 85.0% for non-diabetics (p = 0.0002). On multifactorial analysis diabetic patients showed a risk of late mortality six times greater than non-diabetics. In conclusion rehabilitation after vascular amputation is feasible in a large number of patients, despite a limited life span. Diabetes represents a major risk factor both for life and for the opposite limb. Knee preservation is an important factor for better rehabilitation.
