Venous rupture complicating hemodialysis access angioplasty: percutaneous treatment and outcomes in seven patients.
OBJECTIVE
To evaluate percutaneous treatment options for preserving hemodialysis access after angioplasty-related venous rupture, we retrospectively reviewed the charts for all dialysis access angioplasties performed over a 33-month period. Seven cases of venous rupture after venous angioplasty were identified (four men and three women; mean age, 63.5 years). Treatment included observation only (n = 1), a second prolonged balloon inflation at the rupture site (n = 2), stent insertion (n = 5), and manual graft occlusion (n = 1). Treatment was successful in eliminating contrast extravasation in all patients while maintaining immediate graft function in six out of seven patients. None of the patients required emergent surgical intervention. The mean primary and secondary patency rates of the salvaged grafts after intervention were 2.3 and 9.3 months, respectively. Five of seven access sites were still patent at the most recent follow-up.


CONCLUSIONS
Prolonged balloon inflation or placement of a stent may salvage hemodialysis access in most patients after angioplasty-related venous rupture. Primary and secondary patency have proven to be satisfactory.
