Utilization of Disposable IV Infusion Sets as Temporary Vascular Shunts in Major Limb Replantation
Overview
This retrospective study evaluated the use of disposable intravenous infusion sets as temporary intravascular shunts (TIVS) in 67 patients undergoing major limb replantation. The use of TIVS significantly reduced amputation rates and compartment syndrome incidence compared to no shunt use, demonstrating improved early limb salvage outcomes.
Background
Limb replantation success has improved with microsurgical advances, but ischemia‒reperfusion injury remains a major cause of poor outcomes, including limb necrosis. Timely restoration of blood flow is critical to reduce ischemic damage. Temporary intravascular shunting (TIVS) provides a rapid bridge to restore distal limb perfusion during surgery. Although initially described in military settings, TIVS using silicone tubes has shown promise in civilian limb replantation, but controlled clinical data are limited. This study investigates the clinical effect of using disposable IV infusion sets as TIVS in major limb replantation.

Key Findings
Use of disposable IV infusion sets as temporary vascular shunts was feasible and quick, averaging 10 ± 1.5 minutes for installation.
After shunt placement, distal limb perfusion improved, evidenced by color change, increased skin temperature, and palpable distal pulses.
The shunt group had a statistically significant lower amputation rate compared to the no shunt group (p < 0.05).
Incidence of compartment syndrome was significantly reduced in the shunt group (p < 0.05).
No significant differences were found between groups in thrombosis rate or need for vascular revision surgery.
Demographic and injury characteristics were comparable between groups, supporting the validity of outcome differences.
Clinical Implications
Temporary intravascular shunting using readily available disposable IV infusion sets can be an effective and rapid technique to restore blood flow during major limb replantation. This approach reduces ischemia time, lowers amputation and compartment syndrome rates, and may improve early limb salvage without increasing thrombosis or vascular revision risks. Surgeons should consider TIVS as a valuable adjunct in complex limb replantation procedures.
Conclusion
The use of disposable IV infusion sets as temporary vascular shunts in major limb replantation is a practical and effective method to improve early limb salvage outcomes by reducing amputation and compartment syndrome rates. This technique warrants broader clinical adoption and further prospective evaluation.
