Seven patients with concomitant atherosclerotic iliac stenosis and femoral artery occlusive disease were treated with polyvinyl balloon catheter dilation of the iliac artery and subsequent distal operative arterial reconstruction. The iliac lesions were short, localized, common and external iliac stenoses and the femoral lesions were superficial femoral artery occlusions in six patients and a common femoral occlusion in another. All seven iliac stenoses were successfully dilated. Subsequent operative femoral artery reconstruction was successful in these patients, with restoration of popliteal or pedal pulses and relief of ischemic symptoms over a follow-up period of two to 14 months. One patient's femoral popliteal bypass graft thrombosed four months postoperatively.
The technique of transluminal dilatation of arterial stenoses has been greatly facilitated with the recent development of the vinyl balloon catheter by Gruntzig. Since these catheters became available to us in early 1978, we have utilized them to attempt dilatation of 62 arteries, including iliac, femoral and renal vessels. Immediate success was achieved in 57 of these vessels. There were five early complications (two distal embolizations and three prompt occlusions) and three late complications (two restenoses and one occlusion at ten days). The occlusions were all treated promptly surgically with good results and the stenoses redilated. Noninvasive pressure measurements were obtained on all patients whose iliac or femoral arteries were dilated both before and after the procedure, with objective improvement demonstrated by this method. The procedure itself is well tolerated by patients. It involves only minimal discomfort and risk and a markedly shortened hospital stay. The procedure can be easily accomplished by physicians who are thoroughly familiar with routine femoral catheterization techniques and it is believed that this technique will have a definite place in the future therapy of many cases of arterial stenosis.
Percutaneous balloon catheter angioplasty appears to be an effective method of treatment for localized iliac artery stenosis. Results of our experience demonstrate that it can be accomplished with an acceptable morbidity in carefully selected patients and can be done and even repeated with minimal inconvenience to the patient.
Percutaneous balloon catheter dilation was used to treate 12 high-grade stenoses in ten autogenous vein bypass grafts since September 1978. Four lesions occurred in femoropopliteal grafts, seven in femorotibal grafts, seven in femorotibial grafts, and one in an axillofemoral graft. Balloon catheter dilation was successful and surgery avoided in 11 of the 12 lesions. Pedal pulses were restored in eight of the ten patients, and the pulse in a femorotibial bypass graft was improved in another. Postdilation arteriography demonstrated a substantial increase in luminal diameter, and ankle pressure indexes were improved in all successful cases. The tenth had an operative correction of the stenosis. There were no complications with the procedure. Percutaneous balloon catheter dilation appears to be an effective method of treating stenosis in autogenous vein grafts and a useful alternative to surgical revision.
The use of silastic catheters for total parenteral nutrition has greatly expanded. Their decided advantages of flexibility and minimal thrombogenicity favor their use in the long-term nutritional support. This case report details the development of central vein thrombophlebitis associated with an indwelling central silastic catheter. This uncommon hazard of central venous catheterization is not eliminated by the use of silastic catheters.
