Modified technique of cavoatrial tumor thrombectomy without cardiopulmonary by-pass and hypothermic circulatory arrest: a preliminary report.
INTRODUCTION: Traditionally, tumor thrombi extending into the right atrium have been managed by open surgery with sternotomy, cardiopulmonary bypass circulation and hypothermic circulatory arrest, and are associated with significant morbidity and mortality rates. Here, we evaluate the results of cavoatrial thrombectomy using our own, Foley catheter assisted-technique, obviating the need for thoracotomy, extracorporeal circulation, and/or hypothermic circulatory arrest.
MATERIAL AND METHODS: Between June 2013 and January 2015, 4 consecutive patients underwent cavoatrial thrombectomy performed with our own, Foley catheter assisted technique, via Chevron incision, with no need for extracorporeal circulation or hypothermy for renal cell carcinoma with tumor thrombus extending into the right atrium. Analyses of patients' data from a prospectively maintained database with respect to perioperative characteristics, morbidity and mortality were performed.
RESULTS: The total mean duration of surgery was 255 minutes. The mean time of total IVC (inferior vena cava) occlusion was 90 seconds. The average blood loss volume, timed from the beginning of cavotomy incision until its closure, was 1200 ml. The total mean intraoperative blood loss was 3,150 ml. There was no perioperative death. Postoperative complications included one transient acute kidney injury requiring one-off hemodialysis and one re-operation due to bleeding. The follow-up time ranged between 12 to 17 months. None of the patients developed disease recurrence. All patients were still alive at the time of study completion.
CONCLUSIONS: Obtained results support the validity of our own, Foley catheter assisted technique, without cardiopulmonary bypass and hypothermic circulatory arrest for the treatment of renal cell carcinoma with tumor thrombus extending into the right atrium.
