Stents in the treatment of renal artery stenosis: long-term follow-up.

Purpose: To evaluate the role of percutaneous stenting in the treatment of renal arterial lesions after failure of balloon angioplasty.

Methods: Two hundred ten patients (139 males; mean age 67.7 +/- 9.

Percutaneous endoluminal treatment of iliac occlusions: long-term follow-up in 105 patients.

Purpose: To evaluate the long-term results of percutaneous recanalization techniques in occluded iliac arteries.

Methods: Percutaneous recanalization was attempted in 105 patients (97 men; mean age 56 years, range 34 to 80) with iliac occlusions using thrombolysis (n = 15), excimer laser (n = 4), mechanical thrombectomy (n = 16), balloon angioplasty alone (n = 23), and angioplasty plus stenting (n = 69). The majority of lesions (n = 72) were in the common iliac artery (CIA); 33 were in the external iliac artery (EIA).

Clinical experience with a new nitinol self-expanding stent in peripheral arteries.

Purpose: To evaluate a new self-expanding nitinol coil stent in stenotic or occluded peripheral arteries.

Methods: Seventy-three symptomatic patients (58 men; mean age 67 years) were treated with nitinol stents for lesions in the iliac artery (9 stenoses); superficial femoral artery (SFA) (39 stenoses, 6 occlusions); popliteal artery and tibioperoneal trunk (9 stenoses, 7 occlusions); and 3 bypass grafts. Mean diameter stenosis was 84.

Palmaz stent placement in iliac and femoropopliteal arteries: primary and secondary patency in 310 patients with 2-4-year follow-up.

Purpose: To define the long-term outcome of stent placement in iliac and femoropopliteal arteries.

Materials And Methods: Three hundred ten patients received 418 balloon-expandable Palmaz stents. Two hundred thirty stents were implanted in iliac arteries of 184 patients, and 188 stents were implanted in femoropopliteal arteries in 126 patients.

Case report: recurrent anaphylactic shock to radiographic contrast media. Evidence supporting an exceptional IgE-mediated reaction.

A rare case of anaphylaxis to iodinated contrast media is reported. The patient underwent two anaphylactic shocks to intravenous administration of radiocontrast agents. Specific IgE were suspected on the basis of positivity of intradermal tests and human basophil degranulation tests.
