Abstract
Purpose
The treatment of occluded saphenous vein graft (SVG) is challenging, and thus preventing the graft occlusion is of utmost importance. However, despite its recognized importance, a paucity of data exists regarding how SVGs are handled and preserved. Hence, this survey was conducted to document the techniques of vein graft preservation and handling among cardiac surgeons in India.
Methods
The survey had 26 questions regarding vein graft usage, harvesting, handling, and preservation techniques. Three hundred cardiac surgeons across India participated in this survey between March 2019 and July 2019.
Results
Responses were received from 215 (71.6%) surgeons across 13 states. Around 87% of respondents reported that ≥ 76% of veins were harvested by the open technique. Among the respondents, around 67% used one SVG in ≥ 96% of their patients, 45% used two SVGs in ≥ 86% of their patients, and 38% used ≥ 3 SVGs in < 25% of their patients, respectively. Around 54%, 27%, 9%, and 9% of respondents used autologous whole blood, saline solution, pH-buffered solution, and other solutions, respectively. In addition, 96.74% of respondents heparinized their vein graft preservation solutions, and 98.14% preserved the solution at room temperature. 34.88% and 83.26% of respondents used dual antiplatelet therapy (DAPT) before and after surgery in ≥ 76% of their patients, respectively. 63.26% of the surgeons reported that the patients received DAPT for > 12 months.
Conclusion
There is a significant variance in the process of vein harvesting, preservation, handling, and antiplatelet therapy protocols among various cardiac surgeons across India. Therefore, there is a need for standardization in the practice of vein harvesting.
