Surgical technique and outcomes associated with the use of femoral vein in venous reconstruction for superior vena cava syndrome.

Objective: Superior vena cava syndrome (SVC) is a debilitating disease, and surgical reconstruction has been described with some of the best results using spiral great saphenous vein (SGSV) grafts. SGSV grafts can be difficult to construct, and a long segment of saphenous vein is needed. Femoral vein has been an excellent conduit for infected aortic and peripheral reconstructions in our hands, and we sought to review outcomes using this conduit for SVC reconstruction.

Methods: This was a single-center, retrospective study that included all patients who underwent SVC reconstruction using femoral vein from January 2000 to December 2023. Follow-up period analysis included reconstruction patency, surgical reinterventions, patient's symptoms, and complications.

Results: Ten patients underwent central venous reconstruction or bypass using the femoral vein, with an average age of 51.88 years ± 10.20 years. SVC syndrome was primarily caused by benign etiologies including pacemakers and indwelling central venous catheters. Common presenting symptoms included head or neck fullness and upper extremity edema. The median follow-up duration was 21 months. Primary patency at 1 year was 79%.

Conclusion: Femoral vein reconstruction presents a promising solution for managing SVC obstruction, offering effective symptom relief and acceptable venous patency rates. Further research including prospective trials and comparative studies is crucial to refining surgical techniques and understanding long-term efficacy in addressing this complex clinical issue.
