Percutaneous endovascular treatment for acute brachial artery injury: clinical results of 26 cases / 介入放射学杂志

ABSTRACT

Objective To investigate the clinical effect of percutaneous endovascular treatment for acute brachial artery injury.Methods The clinical data of 26 patients with acute brachial artery injury,who were treated at authors' hospital during the period from January 2005 to February 2014,were retrospectively analyzed.Brachial artery occlusion was proved by angiography via femoral access,and the extent and degree of arterial obstruction were verified.The radial artery of the affected side was punctured when antegrade recanalization of the occlusion failed.By using bidirectional subintimal recanalization technique,the working guide wire channel was established,which was followed by balloon dilatation and stent implantation.Results Technical success rate was 100％.All the 26 patients were followed up for 6-36 months,among whom vascular patency was kept in 21 and stent stenosis was observed in 5,for these patients balloon dilation had to be carried out immediately and the blood flow returned to normal rapidly.During the follow-up period,no ischemic necrosis occurred and no amputation surgery was needed.Conclusion In treating acute brachial artery injury,percutaneous endovascular therapycan quickly open the brachial artery lumen and restore the blood flow,the clinical effect is very significant.
