Why the study?
Does temporary arterial and venous bypass allow safe resection in patients with retroperitoneal sarcomas affecting large abdominal vessels?
Does temporary arterial and venous bypass allow safe resection in patients with retroperitoneal sarcomas affecting large abdominal vessels?
Temporary arterial and venous bypass facilitates the resection of complex retroperitoneal sarcomas with good oncologic outcomes, though venous graft occlusion remains a risk.
Should not yet change practice for vessel-involved sarcomas; hypothesis-generating for bypass feasibility amid venous occlusion risk.
Retroperitoneal sarcomas that simultaneously affect large abdominal vessels are rare. Tumour resection and vascular clamping may take a long-time, and possibly have significant local and systemic consequences. For this reason, temporary arterial and venous bypass may be useful. Three patients underwent operation with utilization of this technique, which made it possible to resect tumour masses with a shorter duration of ischaemia, while maintaining venous return. These patients remain free of disease after an average follow-up of 37 months, without any arterial graft complications. Two of the patients progressed to symptomatic occlusion of the venous graft after the perioperative period.
