چکیده

BACKGROUND Traditionally, extensive prosthetic arteriovenous (AV) graft infection is treated with graft removal and the arteriotomy or the graft stumps were simply sutured following the removal of the graft. However, postoperative bleeding may occur which requires emergent intervention. We report the results achieved at our clinic after arteriotomy repair with venous graft interposition in re-bleeding conditions. METHODS From January 2000 through February 2001, 31 patients with extensive graft infections underwent graft removal with direct closure of the arteriotomy or graft stumps at our clinic. Seven of these patients experienced re-bleeding from the repaired brachial artery. Six of them received repair of the brachial artery with venous graft interposition and one received brachial artery ligation. RESULTS Surgery of the infected dialysis graft removal was associated with a high re-bleeding rate (22.6%) in our group. In this study, we analyzed the preoperative data, including age, gender, incidence of diabetes mellitus, incidence of peripheral artery occlusive disease, and preoperative blood culture. Both univariate and multivariate analyses showed that the positive preoperative blood cultures were the only factors related to postoperative bleeding (Odds Ratio 22.8, p = 0.009 < 0.05). All of the patients that received brachial artery repair with venous graft interposition recovered well. CONCLUSION In the patients with positive blood cultures, we recommended brachial artery repair with venous graft interposition rather than simple closure of the arteriotomy or graft stump after removal of the infected graft. This may prevent re-bleeding due to inadequate debridement and eliminate the possibility of ipsilateral hand ischemia due to brachial artery stenosis following simple closure of the arteriotomy.

Over a seven year period from 1982 to 1989,3337 conduits were created in 3137 patients with end stage renal disease (ESRD) as access for chronic dialysis. These included 2690 side-to-side arteriovenous fistulae (A VF), 168 end-to-side A VFs, 10 autogenous vein grafts, 51 homogenous frozen vein grafts, 109 polytetrafluoroethylene (PTFE) grafts, 209 emergency external arteriovenous shunts, t...

The Use of Positron Emission Tomography in the Diagnosis of Prosthetic Arteriovenous Hemodialysis Graft Infection: A Case Study

Patients on chronic hemodialysis (HD) required efficient arterio-venous access. Different types of vascular access are commonly used, such as native arteriovenous (AV) fistula, prosthetic AV graft, central venous catheter, or temporary and tunnelled cuffed catheters. Vascular access—related morbidity remains the major issue for patients requiring long-term therapy. Vascular access infection con...

Arteriovenous graft infection caused by Candida glabrata: A case report and literature review.

The infection rate of arteriovenous (AV) grafts is high, but fungal etiology is rare. Only five cases of graft infection due to Candida albicans (C. albicans) or C. tropicalis have been described in the literature. Herein, we report the first case of AV graft infection caused by C. glabrata. A 60-year-old woman on maintenance hemodialysis for end-stage renal disease was admitted because of inte...

Iatrogenic brachial artery injuries.

During a 7-year period approximately 700 left heart cardiac catheterizations were carried out via open brachial arteriotomy. Of these, 25 patients with a missing or weak radial pulse after catheterization were referred for operation. Despite minimal early ischaemic symptoms and signs, all 25 patients had a complete occlusion of the brachial artery at the site of the arteriotomy. Commonest cause...

The Impact of Intraluminal Vancomycin Adminstration on Prevention of Hemodialysis CatheterRelated Infections

Introduction: Percutaneously inserted double-lumen central venous hemodialysis catheters provide the nephrologist with an excellent temporary access for an immediate hemodialysis treatment and preserve the peripheral veins for the future creation of a permanent arteriovenous vascular access. Unfortunately catheterrelated infections are usually common. In this study, the impact of intra luminal ...
