Abstract
BACKGROUND
The success of infragenicular revascularisation for lower limb ischaemia is limited by the high proportion of patients without ipsilateral long saphenous vein (LSV) of adequate length or quality. The aim of this study was to report the results of an autogenous vein only policy for infragenicular revascularisation utilising contralateral LSV when ipsilateral LSV is inadequate. The treatment and outcome of infection of autogenous grafts with methicillin resistant Staphylococcus aureus (MRSA) is also reported.
PATIENTS AND METHODS
The vascular audit database and patient case notes were reviewed retrospectively for patients with arterial occlusive disease requiring infragenicular reconstruction. There were 68 critically ischaemic legs in 65 patients of whom 48 were male: median age (range) 74 years (41-94), over a three year period.
RESULTS
Thirty six patients (53%) underwent revascularisation (eight infragenicular femoropopliteal bypass, 28 femorodistal), 24 (35%) underwent primary amputation and a further eight (12%) were found to have unsuitable distal vessels for revascularisation after tibial vessel exploration and intraoperative angiography. Thirty three grafts (92%) utilised LSV and three (8%) were polytetrafluoroethylene grafts. Thirteen patients (39%) lacked adequate ipsilateral LSV of whom 12 had the contralateral leg explored providing suitable LSV in 10/12 (83%). Contralateral LSV was used as a single length conduit in two cases and as a venovenous composite graft in eight cases. Primary, primary assisted, and secondary patency rates at two years were 38%, 77%, and 81% respectively. Actuarial limb survival and patient survival rates at two years were 86% and 61% respectively. Eleven patients developed ipsilateral wound complications (30%) including seven (21%) who developed MRSA infection of the ipsilateral leg wound. MRSA wound infection was treated successfully in all cases by antibiotic therapy (intravenous vancomycin). No patient subsequently required saphenous vein harvesting for a secondary reconstruction or coronary artery bypass graft.
CONCLUSION
Excellent long term results can be achieved using autogenous vein for infragenicular revascularisation and the contralateral LSV is an excellent alternative in the absence of suitable ipsilateral LSV. Autogenous vein may confer some protection against severe complications observed with MRSA infection seen in vascular patients and therefore its use is recommended.
