Early Outcomes of Complex Vascular Reconstructions in Lower Extremities Using Spiral and Panel Vein Grafts.

BACKGROUND

Spiral saphenous vein grafts (SSVG) or paneled vein grafts (PVG) can be used when the diameter of the autologous great saphenous vein does not match the vessel that needs to be repaired. This study aimed to present early results of complex vascular reconstruction with SSVGs and PVGs in the lower extremities.

METHODS

From May 2019 through January 2021, 6 SSVGs and 3 PVGs were used for vascular reconstruction in 9 patients. Patient data were collected retrospectively, including age, gender, cause of vascular pathology, target vessels, concomitant injury, surgical method, additional surgical methods, and hemodynamic status. The Kaplan-Meier method was used to calculate the rate of freedom from reintervention.

RESULTS

Among these patients, 7 had trauma, 1 had graft infection, and 1 had vascular reconstruction after tumor excision. The mean duration of follow-up was 6 ± 6.6 months (range 1-19 months). The rate of freedom from reintervention for any reason was 77.8% at 1 year. Two patients underwent amputation after vascular reconstruction with patent vascular reconstructions. One of the 2 amputations was performed because of infection, and the other was due to ischemia >24 hr. The success rate of reconstruction was 100%, and the primary patency rate was 100%. The rate of limb salvage was 77.8%. There was no death, bleeding, embolism, skin ulcers, graft-related complication, or aneurysmal dilation during follow-up.

CONCLUSIONS

SSVG and PVG were associated with low infection rates and satisfactory short-term patency rates. Both 2 grafts may be good choices when there is a diameter mismatch in vascular reconstructions.
