Abstract

This study assessed safety of the distal occlusion washout (DOW) method for prevention of no-reflow during stenting of degenerated saphenous vein grafts (SVGs). The DOW method involves protection of distal native coronary circulation with an occlusive balloon during the pretreatment and washout steps prior to stenting. Outcomes of stenting of 23 grafts in 21 patients after pretreatment with the DOW method were evaluated. The mean graft age was 7.4 ± 4.3 years. The mean treated lesion length was 53 ± 28 mm. Total occlusions were treated in 6 grafts and thrombotic lesions in 10 nontotally occluded grafts. One non-Q-wave MI and one acute stent thrombosis were observed. No deaths, Q-wave MIs, or subacute thromboses occurred. Follow-up in 18/21 (85.7%) patients at 28 ± 8 weeks demonstrated target graft revascularization in 1 (5%) patient. The DOW method prevented clinically significant no-reflow in all 23 degenerated SVGs stented.
