Objectives
There is no firm treatment strategy of coronary artery bypass grafting in hemodialysis patients. We investigated postoperative outcomes in hemodialysis patients undergoing isolated coronary artery bypass grafting using in situ skeletonized gastroepiploic artery.
Methods
From January 2002 to December 2019, 143 hemodialysis patients underwent isolated coronary artery bypass grafting in our institution. Among them, 49 consecutive patients with gastroepiploic artery grafting were retrospectively analyzed.
Results
No patient was converted from off-pump to on-pump surgery. The mean distal anastomoses were 3.6 ± 1.0 per patients. Seven patients (14.3%) required proximal anastomosis to aorta. Thirty-day mortality was 4.1% (2 of 49). The early (3–20 days after surgery) patency rate of the gastroepiploic artery was 96.9% (63 of 65 anastomoses). The adjusted rates of survival free from overall death at 1, 5 and 10 years after surgery were 91.7%, 72.6% and 32.5%, respectively. Multivariate Cox proportional hazard regression analysis showed that age (hazard ratio 1.131, 95% confidence interval 1.055–1.212, p < 0.001) and LVEF < 40% (hazard ratio 9.411, 95% confidence interval 1.963–45.919, p = 0.005) were independent predictors of mid-term death from all causes (Table 6).
Conclusions
Short and mid-term outcomes were acceptable. The use of in situ skeletonized gastroepiploic artery can decrease the time of touching aorta, so gastroepiploic artery grafting may be an important option for coronary artery bypass grafting in hemodialysis patients with limited conduits.
