Objectives: Critical hand ischemia due to vascular access-induced steal syndrome continues (VASS) to be a significant problem. The aim of this study was to examine the outcomes of endovascular interventions in the upper extremity of patients presenting with VASS.
Methods: A database of patients presenting with documented VASS between 2006 and 2016 was retrospectively queried. Patients who underwent isolated endovascular intervention in the upper extremity were analyzed.
Results: 98 patients (66% female, average age 65 years) presented with VASS: 28 presented with upper arm atherosclerotic disease and the remainder with below elbow atherosclerotic disease. 93% presented with rest pain and the remainder with minor digital ulceration. 76% of the patients had arterio-venous fistulas (majority with a brachial artery origin) and the remainder had upper arm prosthetic AV grafts. Of those with upper arm disease, 1/3 of the patients had subclavian occlusive disease and 2/3 had brachial artery occlusive disease. Patients with subclavian disease underwent stent placement and patients with brachial artery disease underwent balloon angioplasty. Technical success was 100%. 91% of the patients had symptomatic success at 30 days and the remainder required access proximalization. Of those with below elbow disease, all had disease in the forearm vessels with 42% having either the ulnar or radial artery occlusion. Balloon angioplasty was performed in 1 vessel in 55% and in 2 vessels in 45% of the patients. Technical success was 79% with 51% of the patients having symptomatic success at 30 days; of those who remained symptomatic 76% required proximalization of the access and 24% required ligation. The MACE rate was 4%. The 30-day mortality rate was 0% and the morbidity rate was 7%. At 5 years, cumulative patency was 71±9% and 41±8% for the upper arm and forearm interventions respectively. The 5-year freedom from re-intervention was 92±9% and the 5-year freedom from recurrent VASS was 93±8%. The predictors of endovascular success were one vessel forearm runoff, an intact palmar arch and presence of digital run-off.
Conclusions: Upper extremity interventions for VASS are associated with a high rate of success (62%) with no mortality and a low morbidity. In correctly selected patients, endovascular interventions of the upper and forearm vessel have a role in the management of VASS.
