Percutaneous transluminal angioplasty of the abdominal aorta.

PURPOSE: To determine the long-term results of percutaneous transluminal angioplasty (PTA) of focal infrarenal abdominal aortic stenoses. PATIENTS AND METHODS: Over a 10-year period, 15 focal infrarenal abdominal aortic stenoses were treated with PTA in 14 patients (13 women and one man; mean age, 53.2 years; range, 43-78 years). RESULTS: The initial technical success rate was 100%. Clinical patency, as defined by continued absence or improvement in symptoms after PTA, was achieved in 14 of the 15 angioplasty procedures (93%) with a mean duration of clinical follow-up of 4.3 years (range, 0.6-9.8 years) in the 14 patients. Long-term noninvasive follow-up demonstrated continued patency of the angioplasty site in 11 of 11 patients available for study. The mean ankle-arm index in these 11 patients was 0.95 (range, 0.9-1.0) at a mean follow-up of 4.8 years (range, 0.6-9.8 years). There was no significant morbidity or mortality associated with the angioplasty procedures. CONCLUSION: In view of the high degree of technical success and the excellent long-term patency, we believe that PTA should be considered a primary method of treatment in properly selected patients with focal abdominal aortic stenoses.

Supra-aortic arterial stenoses: management with Palmaz balloon-expandable intraluminal stents.

PURPOSE: The authors report on the use of Palmaz balloon-expandable intraluminal metallic stents to supplement conventional balloon angioplasty and to primarily treat a variety of supra-aortic arterial atherosclerotic lesions manifested by claudication or embolic phenomena. PATIENTS AND METHODS: Results from a series of seven patients are reported. Five patients received stents following percutaneous balloon angioplasty (PTA): four patients received five stents for suboptimal initial result of PTA and one patient received one stent for early restenosis following successful PTA. Two patients received three stents primarily: one patient had one stent placed for a highly eccentric innominate lesion and the other patient had two stents placed for an ulcerated nonocclusive subclavian lesion causing blue digits. RESULTS: Treatment produced immediate angiographic or hemodynamic improvement in all seven patients. Clinical follow-up was obtained on all patients (mean, 10 months; range, 3-18 months). One patient had an episode of vertigo after PTA of a right subclavian lesion that resolved after thrombolytic therapy and stent placement. CONCLUSION: The placement of metallic stents in supra-aortic arteries represented an effective adjunct to PTA of atherosclerotic stenoses in these vessels. Primary stent placement may be an effective treatment for selected lesions.

Disseminated histoplasmosis diagnosed by percutaneous needle biopsy of a retroperitoneal lymph node. A case report.

A case of disseminated histoplasmosis diagnosed by percutaneous needle biopsy cytology is reported. The patient presented with fever and pancytopenia. Computed tomography (CT) revealed retroperitoneal lymphadenopathy. Cytology smears prepared from a CT-guided screw needle biopsy of one of the lymph nodes showed numerous histiocytes with intracytoplasmic yeast forms consistent with Histoplasma capsulatum. Fungal cultures prepared from additional needle biopsy material confirmed the diagnosis. This case illustrates the utility of needle biopsy in the evaluation of radiographically detected retroperitoneal lymphadenopathy and in the rapid diagnosis of infectious disease in certain clinical settings.
