Objective Initial enthusiasm for use of cryopreserved arterial allografts was subsequently tempered by suboptimal long-term outcome. Thrombosis, anastomotic pseudo-aneurysm, allograft disruption, aneurysmal degeneration, recurrent intestinal fistulization, and persistent infection are commonly reported in series with long-term follow-up. The authors reviewed their experience over the past 15 years with the use of cryopreserved arterial allografts as a vascular substitute for vascular prosthetic infection or for primary arterial infection, to investigate allograft-related complications. Material and methods A retrospective analysis of prospectively collected data was conducted for 103 cryopreserved arterial allografts inserted in 96 patients between July 2000 and July 2015. There were 78 patients with infected vascular prosthesis (IVP), nine patients with an aorto-enteric fistula (AEF), and nine patients with primary arterial infection (PAI). Results The in-hospital mortality was eight out of 78 (9%) IVP patients, three out of nine AEF patients, and zero out of nine PAI patients. Median follow-up was 49 months. Allograft-related re-interventions were necessary in 29% of the patients with IVP and four of the patients with AEF, but none of the patients with PAI. Five-year survival for the IVP, AEF, and PAI patients was 53%, 44%, and 90%, respectively. Conclusion This series highlights some shortcomings of cryopreserved arterial allografts in the long term, including suboptimal outcome-results and shortage of material. The authors discuss the allograft-related complications and suggest some tricks to minimize their risk.

Autogenous reconstruction is a well-accepted alternative treatment for prosthetic infection after reconstructive arterial surgery. Because of its technical complexity and the lack of suitable substitutes, the procedure remains limited to a few selected centers. We describe four patients with prosthetic infection after reconstructive surgery for lower limb ischemia. Treatment consisted of prosthetic excision and aortofemoral grafting with the use of the superficial femoral vein. All patients survived the operation and infection was eradicated in all cases. We conclude that the superficial femoral vein represents an acceptable arterial conduit in the treatment of these difficult cases.

Hemostasis obtained by manual compression after femoral artery catheterization results in consistently low rates of major complications. A rare complication of femoral artery catheterization is arterial infection. Its occurrence after diagnostic angiography using manual compression has not been reported. We report two cases of femoral arterial infection after uneventful diagnostic catheterization in nonimmunocompromised patients using the perclose percutaneous arterial closure device. Our cases are representative of perclose associated infections, with delayed presentation of a staphylococcal arterial infection requiring arterial debridement and reconstruction. This article indicates that perclose use carries a risk of severe arterial infection. Surgeons should be aware of the potential infectious complications associated with perclose use and the need for aggressive treatment. (J Vasc Surg 2001;34:983-5.)

Primary arterial infections continue to be one of the most challenging clinical problems encountered by vascular surgeons, and postoperative graft infection one of the most feared complications. As vascular infections present grave risks to life and limb, vascular surgeons must be fully informed concerning prevention, early diagnosis and prompt vigorous treatment. Much new information is available in recent years about arterial infection. New culture techniques have forced us to examine the prospect that a disturbingly high percentage of diseased arteries routinely harbor bacteria. Additionally, chronic intraaneurysmal thrombus is culture-positive in a

Infection of a vascular prosthesis or an arterial receptor site is one of the most challenging situations for the vascular surgeon. In some instances the standard extraanatomic routes to bypass infected areas cannot be used. Two cases of arterial infection following renal transplantation are presented. An infrascrotal perineal approach for a femorofemoral bypass was used to achieve revascularization of a threatened limb.
