Venovenostomy for Outflow Venous Obstruction in Patients with Upper Extremity Autogenous Hemodialysis Arteriovenous Access

Venovenostomy for Outflow Venous Obstruction in Patients with Upper Extremity Autogenous... Outflow venous obstruction is a common problem in patients with autogenous upper extremity hemodialysis access. Surgical revision to divert blood flow into the patent vein is sometimes possible to restore unobstructed flow. The result of this type of procedure is not yet well known. The purpose of this report is to describe our experience with outflow venovenostomy (VV) to salvage dysfunctional autogenous upper extremity arterial venous access (AVF) threatened by venous outflow obstruction in hemodialysis-dependent patients. All patients who underwent VV procedures between September 1999 and October 2004 were reviewed. Data regarding patient demographics, comorbidities, procedure indications, perioperative complications, as well as postoperative AVF function and patency were gathered from patient charts and dialysis records. A total of 11 patients underwent VV in the study period. The median age of the AVF prior to VV was 14 months, with a range of 4-45 months. Two patients had radial cephalic AVF, and they had VV done in the antecubital fossa. Nine patients had brachial cephalic AVF. Seven of them underwent cephalic vein transposition VV, while two patients had basilic vein transposition. Functional AVF was achieved after 1 month in 10 out of 11 patients. Five patients had no further access interventions, four patients required angioplasty at the VV site to maintain access function, and one patient had access infection requiring surgical revision during follow-up. One patient never achieved access function. Postintervention assisted functional patency was 90% ± 9.5% at 39 months. Median follow-up after VV was 16 months.

Abstract

Outflow venous obstruction is a common problem in patients with autogenous upper extremity hemodialysis access. Surgical revision to divert blood flow into the patent vein is sometimes possible to restore unobstructed flow. The result of this type of procedure is not yet well known. The purpose of this report is to describe our experience with outflow venovenostomy (VV) to salvage dysfunctional autogenous upper extremity arterial venous access (AVF) threatened by venous outflow obstruction in hemodialysis-dependent patients. All patients who underwent VV procedures between September 1999 and October 2004 were reviewed. Data regarding patient demographics, comorbidities, procedure indications, perioperative complications, as well as postoperative AVF function and patency were gathered from patient charts and dialysis records. A total of 11 patients underwent VV in the study period. The median age of the AVF prior to VV was 14 months, with a range of 4-45 months. Two patients had radial cephalic AVF, and they had VV done in the antecubital fossa. Nine patients had brachial cephalic AVF. Seven of them underwent cephalic vein transposition VV, while two patients had basilic vein transposition. Functional AVF was achieved after 1 month in 10 out of 11 patients. Five patients had no further access interventions, four patients required angioplasty at the VV site to maintain access function, and one patient had access infection requiring surgical revision during follow-up. One patient never achieved access function. Postintervention assisted functional patency was 90% ± 9.5% at 39 months. Median follow-up after VV was 16 months. Outflow VV is a viable surgical option for selected patients with failing AVF due to venous outflow obstruction.
