Iatrogenic Obstruction of Superior Vena Cava During Cardiac Surgery
Received Date: August 16, 2021; Published Date:August 28, 2021
Introduction
With recent advances in cardiac surgery and advanced imaging modalities, many complex cardiothoracic surgeries are performed. These interventions involve Vascular procedures like CABG/aneurysm repair along with heart valve repair or replacement. These interventions are clubbed together to be completed in one theatre visit. Total cardiopulmonary bypass (CPB) during such operation becomes inevitable. Superior and Inferior Vena cava are cannulated with caval snares to direct venous return to bypass machine instead of the right side of the heart during CPB. Venous drainage from the head and neck region, including brain and upper limb, is dependent on superior vena cava (SVC). Any obstruction to SVC drainage can lead to venous engorgement and SVC obstruction syndrome. We encountered such complication due to Iatrogenic obstruction to SVC drainage.
