Intracardiac caval tumour thrombi (ICTT-IV) were associated with higher surgical mortality (15% vs 5%) and morbidity (64% vs 36%) compared to extracardiac thrombi (ICTT-III).
What are the surgical outcomes and complication rates for patients undergoing resection of intrathoracic caval tumour thrombi?
Surgery for intrathoracic caval tumour thrombi carries high morbidity and mortality, particularly for intracardiac thrombi, highlighting the need for cardiothoracic team involvement.
Absolute Event Rate: 15% vs 5%
Background . Retroperitoneal tumours propagate intrathoracic caval tumour thrombi (ICTT) of which we consider two subgroups: ICTT-III (extracardiac) and ICTT-IV (intracardiac). Methods . Case series review. Results . 29 series with 784 patients, 453 with extracardiac and 331 with intracardiac ICTT. Average age was 59 years. 98% of the tumours were RCC, 1% adrenal and Wilms’ tumours, and 1% transitional cell carcinomas. The prevalent incision was rooftop with or without sternotomy. Mortality was 10% (5% for ICTT-III, 15% for ICTT-IV). Morbidity was 56% (36% for ICTT-III, 64% for ICTT-IV) and reoperation for bleeding was the commonest complication (14%). Mean Blood loss was 2.6 litres for ICTT-III and 3.7 litres for ICTT-IV. Mean blood product use was 2.4 litres for ICTT-III and 3.5 litres for ICTT-IV. Operative and anaesthetic times exceeded 5 hours. Hospital stay averaged 13 days. Variations in perioperative care included preoperative embolisation, perioperative transoesophageal echo, surgical incisions, and extracorporeal circulation. Brief Summary . Surgery for ICTT has high transfusion, operating/anaesthetic time, and in-hospital stay requirements, and intracardiac ICTT also attract higher risk. Preoperative tumour embolisation is controversial. The cardiothoracic team offers proactive optimisation of blood loss and preemptive management of intracardiac thrombus impaction: we should always be involved in the management the ICTT.
Protopapas et al. (Thu,) conducted a review in Intrathoracic caval tumour thrombi (ICTT) (n=784). Intracardiac caval tumour thrombi (ICTT-IV) vs. Extracardiac caval tumour thrombi (ICTT-III) was evaluated on Mortality. Intracardiac caval tumour thrombi (ICTT-IV) were associated with higher surgical mortality (15% vs 5%) and morbidity (64% vs 36%) compared to extracardiac thrombi (ICTT-III).
