Early diagnosis of femorodistal graft stenoses.

Detection and early correction of stenoses following femorodistal bypass grafting may prevent graft occlusion. We studied 43 grafts (36 saphenous vein and 7 human umbilical vein) prospectively by peroperative angiography and then by clinical assessment, post-exercise Doppler ankle pressures and digital subtraction angiography at 1 week, 3 months, 6 months and 1 year. There were 11 grafts inserted for critical ischaemia, 16 for rest pain and 16 for disabling claudication. Four patients died within the year with five patient grafts and these were excluded from the final results. Eight grafts failed during the first year; four within 1 month and a further four subsequently, with no warning alteration of symptoms, ankle Doppler pressure or digital subtraction angiography. Four additional grafts were jeopardized by symptomatic stenoses. Six grafts developed an asymptomatic stenosis of greater than 50 per cent without a change in exercising ankle Doppler pressure. Three symptomatic stenoses were successfully revised but the fourth occluded on conservative management. Three asymptomatic stenoses have also been successfully revised and three have been treated conservatively. Close surveillance of femorodistal grafts is justified by this study but a deterioration in ankle brachial Doppler index was only useful in the patients with recurrent symptoms and was unable to detect half the stenoses of greater than 50 per cent. The detection of these by intravenous digital subtraction angiography might help to avoid graft failure.

PTFE (Goretex) femoropopliteal reconstruction for limb salvage.

We present the results of the use of polytetrafluoroethylene (PTFE, Goretex) grafts for limb salvage in 20 cases of femoropopliteal or more distal arterial reconstruction. There appears to be no relationship between graft survival and 'run-off' or the overall disease state of the vessels. Cumulative graft patency was almost 50% at 6 months, which is in contrast with higher patency rates reported from other countries.

The reproducibility of the treadmill walking test for claudication.

Two standard treadmill walking tests were carried out one week apart upon 117 patients with stable claudication. Although total walking time achieved was reproducible, there was a highly significant delay in the onset of pain during the second test. Absolute limb pressures, determined by Doppler, were reproducible for the group as a whole, although individual variation could be significant. A single walking test is an inadequate assessment of claudication.

The patient's opinion of day care vein surgery.

A questionnaire was sent to 181 patients whose varicose veins had been operated on as day cases. A good response was obtained that showed that day care was generally acceptable except in those cases requiring multiple incisions or stripping.

The results of arterial reconstruction utilizing the profunda femoris artery in the treatment of rest pain and pre-gangrene.

Arterial reconstruction utilizing the profunda femoris artery was performed for rest pain and pre-gangrene in 45 limbs. The preoperative mean ankle arterial pressure index of 0-21 (s.d. 0-12) was increased to 0-52 (s.d. 0-16) in the 22 limbs salvaged by the reconstruction. In 38 limbs a proximal reconstruction was necessary in addition to profundaplasty. At a mean follow-up time of 15-4 months 41-6 per cent of the 36 patients were dead.

Amputation for vascular disease.

Amputation for peripheral ischaemia still has a depressingly high early and late mortality, and morbidity and the end result are usually less than satisfactory. Individual surgeons probably see too few amputees to treat them with maximal efficiency, and these patients create a large burden on beds and resources. There is room for improvement in all aspects of our management of amputees. Primary healing rates might be better with less heroic attempts to obtain a distal amputation. Sepsis is lessened by the use of prophylactic antibiotics. Tight bandaging and the intra-operative fitting of prostheses are undesirable. Simple tests of skin blood pressure may aid prediction of the degree of ischaemia at the proposed level of limb section and the chances of healing. The late mortality is high and merits study of methods designed to reduce it such as long term anticoagulation.
