Double venous drainage through the superior vena cava in minimally invasive aortic valve replacement: a retrospective study

چکیده
AIM To compare the outcomes of patients who underwent upper mini-sternotomy or right mini-thoracotomy and those who underwent full sternotomy and to report a technical improvement in venous drainage by means of double venous cannulation of the superior vena cava (SVC) in mini surgical procedures. METHODS We retrospectively analyzed the outcome of 217 patients who underwent aortic valve replacement through upper mini-sternotomy or right mini-thoracotomy at the Department of Cardiovascular Surgery, University Medical Centre Ljubljana, Slovenia from 1996 till 2010. Cannulation of SVC and right atrial appendage was performed in 142/217 (65%) patients, while in the remaining 75 (35%) patients, double cannulation of SVC was used for venous drainage. The results of patients who underwent mini approaches were compared to 236 patients who underwent full sternotomy for the same purpose from 2009 to 2010 at the same center. RESULTS We found a shorter mean length of intensive care unit stay, less volume chest-tube drainage, shorter crossclamp and cardio pulmonary bypass times, and less postoperative permanent pacemaker implantations in the minimally invasive group patients than in full sternotomy group patients. Using double cannulation of the SVC for venous drainage made venous cannulation in mini approaches easier and eliminated the need for obtaining femoral venous access. CONCLUSION Our study confirmed that even though technically challenging, upper mini-sternotomy and right mini-thoracotomy approaches for aortic valve replacement have potential advantages over conventional median sternotomy. They were proved to be safe, efficacious, and can significantly reduce surgical trauma and are therefore particularly valuable in some higher risk, obese, diabetic and elderly patients. Using double cannulation of SVC for venous drainage made venous cannulation easier and eliminated the need for obtaining femoral venous access.

Methods 236 patients were included in our study, to whom aortic valve was replaced. The purpose of this study was to examine the potential benefit of double venous cannulation through superior vena cava (SVC) for venous drainage for aortic valve replacement (AVR) in upper mini-sternotomy and right mini-thoracotomy approaches. Five to 7 cm skin incision was made at the level of third intercostal...
متن کاملSuperior vena cava cannulation in aortic valve surgery: an alternative strategy for a hemisternotomy approach.
Minimally invasive aortic surgery is increasingly being utilized, in particular, through ministernotomy. The choice of the cannulation site is problematic. Venous cannulation may result in wound complications if the femoral vein is used, or may be bulky if the right atrial appendage is used. Our technique of superior vena cava cannulation not only avoids the risk of complications related to the...

Right atrial procedures require snaring the venous cannulas to prevent air entrapment in the venous line. In particular situations with complex congenital morphology and/or presence of severe pericardial adhesions the right atrial opening without the inferior vena cava cannula in the surgical field and without dissecting and snaring the inferior vena cava itself, might substantially facilitate ...
متن کاملSuperior vena cava syndrome secondary to chronic dissecting aortic aneurysm after aortic valve replacement.
Ascending aortic aneurysm is a rare cause of superior vena cava syndrome. Herein, we describe a case of superior vena cava syndrome caused by a chronic dissecting aortic aneurysm after aortic valve replacement. A successful replacement of the aortic root and ascending aorta led to an improvement of edema of the face and bilateral upper limbs caused by superior vena cava syndrome.

BACKGROUND Minimally invasive robot-assisted cardiac surgery is generally performed nowadays. To avoid the interference of a superior vena cava (SVC) cannula during surgery, it should be inserted before the operation. The position of this cannula is very important because it can cause poor venous drainage during operation. The proper position of the SVC cannula was investigated in the present s...
