| 1 | Treatment of in stent coronary restenosis with excimer laser angioplasty显示文摘Objective To evaluate the efficacy and safety of excimer laser coronary angioplasty (ELCA) with adjunctive balloon angioplasty in patient with in stent restenosis Methods ELCA was performed in 20 patients of in stent restenosis All patients were symptomatic and had class Ⅲ-Ⅳ angina ELCA was performed with the Spectranetics CVX 300 System The laser catheter of Vittesse C (concentric) and E (eccentric) with diameter of 1 4-2 0?mm was used Results Laser catheter crossed all stenotic stents without difficulty The lesion length was 4 6-51 2?mm, mean 20 7±13 7?mm, including 14 lesions >10?mm Laser treatment alone increased minimal lumen diameter (MLD) from 0 3±0 3?mm to 1 4±0 3?mm ( P <0 0001) and improved the diameter stenosis from 88 8%±10 0% to 46 0%±8 0% ( P <0 0001) Adjunctive balloon angioplasty further increased minimal lumen diameter to 2 3±0 7?mm and reduced diameter stenosis to 14 2%±8 2% ( P <0 0001) At follow up (1-17 months, mean 8 9±5 7 months), 17 (85%) patients had remained asymptomatic, 3 (15%) patients had mild to moderate exertional angina, 1 (5%) patient received CABG Conclusion ELCA with adjunctive percutaneous transluminal coronary angioplasty (PTCA) is an efficient and safe technique to debulk tissue in the patient with in stent restenosis The incidence of procedural related complication was low and ELCA may be used as a good method for in stent restenosis | Meilin Liu W.H.Chow O.H.Kwok M.H.Jim A.Yip K.Fan E.Chan | 2000 | Chinese Medical Journal2000，，1： | 0 |
