Deterioration of in-situ vein bypasses: anatomic study of 11 cases.

During the follow-up of 130 patients with in-situ bypasses 11 patients were reoperated following the detection of degenerative changes. The lesions found included anastomotic aneurysms (1), diffuse dilatation (2), localized aneurysms (5), stenosis of valve sites (2), and diffuse narrowing (1). The mean interval for the onset of a lesion was eight months.

[Peroperative measurement of peripheral vascular resistance. Significance for the indications, technic and prognosis of distal bypasses. Apropos of 35 cases].

The authors report their experience of the per-operative measurement of the "absorption capacity" of a distal vascular network. This constitutes an absolute measurement and provides a reliable per-operative indication of a bypass, and eventually that of surgical reintervention in early thrombosis. The techniques are described with a brief overview of the major physical laws in this field.

[Peroperative angiography in reparative surgery of the lower limbs. Apropos of experience with 1099 cases].

The authors report their experience of per-operatory angiography in a series of 1,099 cases over 13 consecutive years. The main interest is the limitation in the rate of early reintervention, which frequently causes morbidity and mortality in this type or surgery. The serial nature of the technique is emphasized, and is most comparable to pre-operatory exploration.

[Are axillo-distal bypasses justified? Apropos of 70 cases over an 8-year period].

Seventy axillary/distal artery shunts were carried out in 67 patients between 1978 and 1985. Mean age of patients was 71.5 years; 34% had coronary disease, 39% respiratory insufficiency, 12% diabetes and 12% severe renal impairment.
