In the past 20 years Hickman catheters have gained increasing acceptance for many uses, including bone marrow transplantation, long-term chemotherapy, total parenteral nutrition, dialysis, and administration of antibiotics and fluids. Until the past decade these catheters were inserted in the operating room. We present our experience in the percutaneous placement of 203 Hickman catheters in an interventional radiology suite in 190 consecutive patients within a period of 30 months. Catheter placement was successful in 202 (99.5%). The main complications were infections, necessitating removal of the catheter in 11 cases (5.4%) and unintentional dislodgement of the catheter in 8 (3.9%) - all in women and most on the right side. Pneumothorax and thrombosis in the catheter each occurred once. In another patient the guide wire broke during insertion and had to be percutaneously removed from the pulmonary artery. Late fracture of the catheter occurred in 2 others in whom the intravascular fragment was removed percutaneously. We believe that percutaneous Hickman catheter placement in the radiology suite offers advantages over traditional surgical placement.

Percutaneous endovascular techniques are well established procedures in the management of peripheral vascular disease and visceral arterial stenosis. They are now being adapted for use in the carotid artery as well. 8 patients with 9 extracranial carotid artery stenoses were successfully treated by percutaneous angioplasty, following which in 4 of them 5 stents were inserted. The stenotic lesions were situated in the proximal internal carotid artery and in its bifurcation and also in the common carotid artery. The indications for angioplasty in these patients were the same as for surgery. There were no major complications. 1 patient had transient hemiparesis lasting a few hours, and another had bradycardia following balloon dilatation in the region of the carotid body. Percutaneous endovascular treatment of carotid artery stenosis is becoming a safe, feasible alternative to surgery.
