title: Multifocal peripheral and coronary angioplasties.
abstract: Multifocal atherosclerotic lesions are frequent. It could thus be expected that multifocal angioplasties (performed in one particular patient on several [iliofemoral, renal, subclavian, mesenteric, coronary] sites) are frequent. To study multifocal angioplasty, we considered the 5344 angioplasties (PTA) (4151 coronary and 1193 peripheral PTA) which had been performed over 10 years in our institution. Eighty PTA (1.5%) were considered as multifocal angioplasty. They were performed in 30 patients who were followed up during 7 to 132 months (mean = 55). In case of primary PTA (72 PTA), the most frequent involved site was the iliofemoral site (47%) followed by renal (35%), coronary (8%), subclavian (7%) and mesenteric sites (3%). Eight PTA were performed after primary failure (3 cases) or after restenosis (5 cases). The 30 patients were divided into 2 groups according to the chronology of multifocal PTA. In group I, 20 patients had multifocal lesions on the first workup and multifocal angiopathy over a short operative period (< 3 months). The 10 patients of group II initially had a single procedure. They subsequently had multifocal angioplasty over a longer period (> 2 years) on different sites of the first PTA. Compared to group I, mean age was lower in group II (46 vs 52 year; ns), primary success rate higher (100 vs 90%; p < 0.05), complications less frequent (3 vs 20%, p < 0.05) and restenosis rate lower (7 vs 21%; p < 0.01). In conclusion, multifocal angioplasty is infrequent. A specific group of patients who had multifocal angioplasty spread over several months or years could be individualized.(ABSTRACT TRUNCATED AT 250 WORDS)
