Short-term outcomes of reconstruction of extensively diseased left anterior descending artery with or without endarterectomy: a propensity score analysis

Abstract Background Surgical management of extensively diseased left anterior descending artery (LAD) is challenging. Reconstruction the LAD with endarterectomy may lead to intimal disruption and affect outcomes surgery. We aimed compare hospital surgical reconstruction without endarterectomy. Results This retrospective multicenter study included 275 patients who had from 2015 2019. divided into two groups: group 1 ( n = 138) plaque exclusion patching, 2 137) patching. All primary isolated on-pump coronary bypass grafting internal mammary (LIMA) LAD. On-lay LIMA patch was used in 118 132 2. A saphenous vein 20 5 Propensity score matching identified 100 matched pairs. The age 56.1 ± 7.8 years versus 55.2 7.1 P 0.34). There were 119 (86.2%) males 113 (82.5%) 0.39). After matching, there no difference preoperative operative data. In groups, low cardiac output occurred 6 (6%) 4 (4%) 0.73). mechanical ventilation time between groups (9 (25th- 75th percentiles: 7.5–14) hours vs. 9 (7–14) 2; 0.93). Length stay 7 (6–9) days (6–10) 0.57). Mortality one patient 1. did not report early graft occlusion cases 1, a myocardial infarction Conclusion after reconstructing or patching are satisfactory comparable both approaches.
