ABSTRACT

A proposta deste estudo foi apresentar uma série de pacientes com doença oclusiva da artéria subclávia tratados por procedimento cirúrgico ou angioplastia. Durante um período de cinco anos, nove pacientes com idade média de 54 anos foram submetidos a seis derivaçöes carótidas-subclávias, uma endarterectomia e duas angioplastias. Os resultados clínicos foram inteiramente satisfatórios em quatro pacientes com sintomas cerebrais, em dois com isquemia de membro e em dois dos três com sintomas mistos. Um paciente faleceu e dois foram perdidos para seguimento. As reconstruçöes permaneceram pérvicas em cinco pacientes entre 12 e 28 meses de seguimento de seguimento mas ocluiu em outro. A revascularizaçäo das artérias subclávia é efetiva tanto com procedimentos cirúrgicos como com a angioplastia.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Os autores apresentam 30 pacientes com doenca aterosclerotica oclusiva aorto-iliaca ou femoro-poplitea nos quais foram empregadas arterias autogenas endarterectomizadas como substituto vascular em situacoes incomuns. Dezenove pacientes tinham oclusao aorto-iliaca e onze obstrucao femoral. Dezesseis pacientes ja haviam sido operados nos correspondentes setores arteriais. Cinco pacientes tinham infeccao associada a proteses arteriais, dois apresentavam pseudo-aneurisma de linha de sutura e em 23 doentes havia apenas isquemia dos membros inferiores.Enxertos mistos com dacron ou veia safena foram utilizados em 17 operacoes, e nas 15 restantes se empregou apenas segmentos arteriais como enxertos. Os resultados foram bons, com apenas duas oclusoes das reconstrucoes e sem complicacoes locais. Tres pacientes falecerem por causas nao relacionadas com os substitutos vasculares empregados

ABSTRACT

Os autores apresentam onze pacientes de hipertensao renovascular por displasia fibromuscular das arterias renais que foram submetidos a tratamento cirurgico. A indicacao cirurgica baseou-se em estudos urograficos e arteriograficos, nao se valorizando valores obtidos em dosagens de renina. Dez pacientes foram submetidos a derivacao aortorrenal e dois a autrotransplante com cirurgia ex-vivo. Nao houve obitos ou perda de rins revascularizados. Os resultados foram bons em nove pacientes com normalizacao das cifras tensionais. Em um paciente ocorreu trombose de ramo da arteria renal esquerda e em outro havia obstrucao da arteria renal contra lateral, tendo ambos permanecio hipertensos

ABSTRACT

Dezesseis portadores de tromboembolismo venoso foram tratados com heparina. Inicialmente fez-se a heparinizacao por via endovenosa em doses diarias de 20.000 a 60.000 U. Apos tres dias a dose diaria foi fracionada entre duas e quatro injecoes subcutaneas. O controle da anticoagulacao foi feito atraves do Tempo de Coagulacao (TC) e do Tempo de Tromboplastia Parcial Ativada (TTPA), mantidos entre 1,2 e tres vezes, entre 1,2 e quatro vezes, os valores previos a heparinizacao, respectivamente. Os testes foram feitos duas horas apos uma injecao e uma hora antes de injecao seguinte.O nivel de anticoagulacao foi mantido de forma constante e homogenea, sendo para tanto, necessarias varias alteracoes nas doses de heparina ou no regime horario de sua administracao em cinco dos 16 doentes. Concluiu-se que atraves do controle com o TTPA, pode-se obter efeito anticoagulante de heparinizacao por via subcutanea semelhante a obtida por via endovenosa desde que a dose e o intervalo de administracao sejam ajustados individualmente

ABSTRACT

Sao apresentados dois casos de fistula arteriovenosa consequente a cirurgia de disco intervertebral. Neles, a expressao clinica mais importante foi a insuficiencia cardiaca refrataria a tratamento habitual.O diagnostico da complicacao vascular foi feito dois e quatro meses apos a correcao da hernia de disco intervertebral, quando, na vigencia de insuficiencia cardiaca, a ausculta abdominal revelou a presenca de sopro continuo epigastrico e periumbilical Num caso, a fistula estava entre a arteria iliaca comum direita e a veia cava inferior e, noutro, entre a aorta e a veia cava inferior. Nos dois casos, foram isolados os segmentos arterias sem disseccao da parte venosa, que foi comprimida por manobras digitais. O fechamento da comunicacao arteriovenosa foi feito por via transarterial. Num caso foi interposta protese de dacron em posicao aortiliaca para restaurar a circulacao arterial (fistula iliaca-cava). Noutro caso a aorta foi suturada primariamente (fistula aortocava)
