【Abstract】 Objective: To evaluate the feasibility and safety of percutaneous transluminal coronary angioplasty (PTCA) and intraccoronary stenting by using the portable fluoroscopic imaging system Methods: From January 1, 1988 to August 20, 1999, 87 patients with a presence of ≥75% diameter luminal narrowing in one or more of major epicardial vessels underwent PTCA and intracoronary stenting Clinical follow up were performed 1～18 months after PTCA in all patients Results: PTCA was performed in 87 patients with 99 diseased vessels and 112 lesions, 36 stents were implanted into LAD, 9 stents into LCX and 17 stents into RCA The clinical (patient), technical (vessel), and lesion success rate was achieved in 95 4%, 94 0%, and 93 1%, respectively Fifty three patietns had complete vessel revascularization of the ischemicrelated vessels and 34 patients had imcomplete vessel revascularization Staged PTCA was performed in 65 patients, one stage of coronary angiography and PTCA in 18 patients, salvage PTCA in 2 patients and direct PTCA in 2 patients During PTCA, death occurred in one patients, 2 stents exited from the balloon before delivered to the target lesion were retrieved with microsnare retrieval system, side branch occlusion occurred in 2 patients, reinfarction in one after PTCA, and large post peritoneal hematoma was observed and operation was performed in one During a mean 12 month clinical follow up, all patients survived The angina recurrence rate was 6 90% (6 of 87 patients), one patients had reinfarction in primary lesion Conclusion: PTCA and intracoronary stenting by using portable fluoroscopic imaging system is effective and relative safe for the management of coronary artery disease更多还原
