Key result
Surgical removal of a relapsing retroperitoneal tumour with resection of involved vessels and thrombectomy under extracorporeal circulation resulted in an uneventful recovery with no relapse at 12 months.
Case Report (n=1)
Surgical removal of a relapsing retroperitoneal tumour with extensive inferior vena cava and right heart thrombosis under extracorporeal circulation can be successfully performed with good 12-month outcomes.
Presented herein is a clinical case report regarding successful treatment of a female patient with a relapsing malignant retroperitoneal tumour complicated by disseminated thrombosis of the inferior vena cava, right atrium and right ventricle of the heart. A relapse of the malignant uterine tumour had developed 3 years after the primary operation and was represented by a large-size mass ingrowing into the infrarenal segment of the inferior vena cava, aorta, as well as jejunum. Additional examination revealed the presence of a tumorous thrombus extending from the primary tumorous node in the lumen of the inferior vena cava to the right atrium and ventricle. The procedures performed consisted in removal of the tumour with resection of the inferior vena cava, aorta, and jejunum, followed by thrombectomy from the right portions of the heart under extracorporeal circulation. The postoperative period turned out uneventful, with no complications observed. The woman was discharged on POD 15. Twelve-month postoperative follow up revealed neither relapse nor progression of the disease. Currently, the patient continues undergoing specific treatment (second-line chemotherapy). Also discussed in the article are current challenges concerning both the classification of tumour thrombosis of the inferior vena cava in retroperitoneal sarcomas, and the choice of optimal strategy and policy of treatment.

Andreichuk et al. (2020) conducted a case report in Relapsing malignant retroperitoneal tumour complicated by disseminated thrombosis of the inferior vena cava, right atrium and right ventricle (n=1). Tumour removal with resection of the inferior vena cava, aorta, and jejunum, followed by thrombectomy under extracorporeal circulation was evaluated on Postoperative complications and disease progression. Surgical removal of a relapsing retroperitoneal tumour with resection of involved vessels and thrombectomy under extracorporeal circulation resulted in an uneventful recovery with no relapse at 12 months.
