Prospective Evaluation of Jugular Vein Thrombi After CPB Cervical Cannulation

The primary objective of the study is to prospectively analyse the occurrence of post-interventional internal vena jugularis (VJI) thrombi after minimally invasive cardiac surgery using a VJI cannula to perform cardiopulmonary bypass (CPB). The study follows the question whether the performance of a jugular cannulation for the operation under CPB regularly causes wall thromboses despite continuous anticoagulation and a short length of stay of a few hours. The thromboses to be assessed for the study will be obtained by bedside (Doppler) sonography by experienced intensive care physicians in the cardiac surgery intensive care unit. A prospective analysis of all minimal invasive procedures performed with regard to thrombi in the VJI.

Inclusion Criteria:- Minimally invasive cardiac surgery carried out using complete cardiopulmonary bypass.Exclusion Criteria:Postoperative support by veno-venous or veno-arterial extracorporeal membrane oxygenation.Complications of neck cannula placement or removal.Pre-existing occlusion of the vena jugularis internaPre-existing thrombosis of the vena jugularis internaPre-existing prothrombotic coagulation disorderExisting catheterisation of the vena jugularis interna within 14 daysPre-existing anatomical anomaly of the vena jugularis interna
