Autologous Great Saphenous Vein Tailored Graft to Replace an Infected Prosthetic Graft in the Groin

Autologous Saphenous Vein Panel Graft for Vascular Reconstruction

BACKGROUND

This study aims to present early and midterm results of vascular reconstruction with saphenous vein panel graft.

METHODS

Between August 2014 and August 2017, 11 saphenous vein panel grafts were used for vascular reconstruction in 10 patients. Patient data including age, gender, etiology of the vascular pathology, concomitant injury, site of injury, surgical procedure, additional surgical procedure, and hemodynamic status were retrospectively collected and analyzed. The Kaplan-Meier method was used to calculate the reintervention and patency rates.

RESULTS

Mean duration of follow-up was 16.5 ± 13.2 months (ranged, 2-39 months). The freedom from reintervention for any reason was 82% at 1 and 2 years. There was no evidence of arterial claudication or venous insufficiency in all patients. The primary patency rates were 82% at 1 and 2 years. There was no mortality, deep venous thrombosis, pulmonary embolism, graft thrombosis, anastomotic stenosis, diameter discrepancy, and aneurysm formation during late follow-up.

CONCLUSIONS

The autologous saphenous panel vein graft enables the surgeon to prepare suitable conduits easily with an appropriate diameter and length for vascular reconstruction. Although long-term results are unknown, this technique provides high patency rates in midterm follow-up, resistance to infection, and low reintervention rates. In conclusion, autologous saphenous vein panel grafts may well be preferred in various vascular disorders that require surgical reconstruction.

[Dilemmas of the reconstruction of the major pelvic artery due to infectious aortic graft complication]

INTRODUCTION

In the pelvic region thrombendarterectomy and bypass procedures are the most commonly performed procedures to treat peripheral artery occlusive diseases with chronic, severe circulation failure caused by atherosclerosis. Biologic and synthetic grafts can also be used in bypass surgeries. Application of synthetic grafts can acutely increase the development of the infectious graft complication and its mortality is still between 70 and 75% in pelvic processes. We describe the difficulties and dilemmas of an infectious aortobifemoral graft.

CASE PRESENTATION

58-year-old female patient with right lower limb trophic ulcer underwent a DSA examination showing a bilateral iliac occlusion and aortobifemoral bypass surgery with Dacron graft implantation was performed. Re-occlusion and infection of the graft led to an in situ silver Dacron graft replacement. Due to the one-sided re-occlusion, a femoro-femoral crossover bypass surgery applying silver graft was performed. Despite the previously described procedures the infectious process got worse and autologous deep vein reconstruction was required beside the removal of the infectious synthetic grafts at the same time.

DISCUSSION

There are local and extraanatomical solutions to reduce infectious graft complication. In pelvic infections bypass surgeries using autologous deep vein can show the best results. This procedure is the trustworthiest but also the most straining technique due to the extension of surgical time and increased blood loss. The proper surgical strategy should be selected on individual bases including cardiopulmonary load ability, patient age and technical/infrastructural possibilities.
