Lupus interstitial cystitis. Apropos of a case]

The poor results obtained with the use of prosthesis in infrapopliteal arterial bypass grafting for critical limb ischaemia led to the introduction of several types of adjuvant arteriovenous fistula to improve the patency and limb salvage rates in patients who have no suitable autologous vein. The main aim of adjunctive arteriovenous fistula in infrageniculate prosthetic bypass is to accelerate the blood flow velocity through the prosthetic graft above the thrombotic threshold level. Since they are subject of great debate among vascular surgeons, the Authors have briefly reviewed the haemodynamic aspects and results reported with the use of such procedures.
