Techniques to avoid hypothermic circulatory arrest in the management of renal tumor with right atrium extension in children

Abstract

Clear cell sarcoma of the kidney is a rare variety of renal tumor accounting for less than 5% of all pediatric renal tumors. Cardiopulmonary bypass along with hypothermic circulatory arrest is frequently used for management of tumor thrombus extending into supra-hepatic inferior vena cava and right atrium. In this paper, we present a strategy of avoiding circulatory arrest and hypothermia and thereby fast-tracking the recovery in managing a case of clear cell sarcoma of the kidney in a 3.5-year-old child with tumor thrombus extending into the right atrium.
