SummaryTo assess the potential advantages of minimally invasive surgery using a single femoral venous drainage method versus femoral venous and superior vena cava or jugular venous drainage method during repeat tricuspid valve surgery.From January 2010 to December 2016, 50 repeat tricuspid valve procedures were performed using a minimally invasive approach without aortic cross-clamping at our institution. The arterial cannula was inserted into the femoral artery, and at the same time, the venous cannula was placed in the femoral vein in 28 patients (FV group) during cardiopulmonary bypass (CPB). The venous cannula was inserted into the femoral vein and the superior vena cava or jugular vein in 22 patients (FSV group).Overall, 36 patients underwent tricuspid valve replacement (TVR) and 14 patients underwent tricuspid valvuloplasty (TVP). The CPB time and operation time, respectively, were 72.96 ± 25.90 minutes versus 78.59 ± 31.95 minutes (P = 0.495) and 170.75 ± 73.31 minutes versus 228.87 ± 61.45 minutes (P = 0.004) in the FV group versus the FVS group. There were no significant differences in the ventilator-assisted time, the first-day LVEF, and the intensive care unit (ICU) stay between the FV group and the FSV group.Both types of drainage were effective and could ensure safety during the operative procedure. The vacuumassisted single femoral venous drainage method simplified the minimally invasive isolated repeat tricuspid valve surgical process more significantly and is the more appropriate choice.(Int Heart J Advance Publication)
The complete surgical resection of malignant thymoma is recommended. We present a rare case of tumor resection and superior vena cava (SVC) reconstruction under veno-venous bypass support from the left internal jugular vein to the left femoral vein. The full amount of systemic heparinization (3 mg/kg) was avoided. The surgical pathology revealed thymic squamous cell carcinoma. No complications such as fatal extensive bleeding, coagulopathy, thromboembolism or transfusion reaction were found postoperatively. The patient was discharged home uneventfully. The support of this veno-venous bypass allows a safe and feasible thymic tumor resection and SVC reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
