Complications from peripheral cardiopulmonary bypass in minimally invasive mitral valve surgery

Abstract

Background: To determine the incidence of peripheral complications associated with peripheral cardiopulmonary bypass (CPB) and to detail cases of severe complications necessitating surgical intervention during peripheral CPB at the HCMC University of Medicine and Pharmacy Hospital. Material and Methods: A cross-sectional, retrospective study on patients who underwent minimally invasive mitral valve surgery with the establishment of peripheral CPB between January 2017 and January 2022. Results: Of the 199 patients who underwent the surgery, 24 cases (12%) experienced peripheral complications. The incidence rates were as follows: femoral artery stenosis from thrombosis at 1.5%, femoral vein occlusion from thrombosis at 0.5%, lower limb compartment compression at 0.5%, and inguinal incision bleeding at 1%. There were no recorded cases of incisional infections in the groin area. Five patients had serious peripheral vascular complications that necessitated urgent surgical intervention. However, no life-threatening complications or deaths during hospitalization were reported. Conclusion: The occurrence of peripheral complications from the initiation of peripheral CPB is relatively low. These complications are manageable and do not diminish the efficacy of peripheral CPB in minimally invasive mitral valve procedures. Key words: peripheral cardiopulmonary bypass, vascular complications, cardiac surgery, minimally invasive surgery, mitral valve surgery.
