Purpose: the purpose of the study was to present a new alternative balloon catheter option for autogenous arteriovenous fistula (avf) dysfunction with a stiff constriction resistant to conventional balloon angioplasty.
Event: a medtronic admiral xtreme balloon was expanded at the stenosis site with a pressure buildup to its working pressure.
The balloon catheter could not be fully expanded at the site of stenosis, as manifested by a ¿¿thin-waist¿¿ (residual stenosis) sign.
Then, the balloon continued to be dilated to its preset burst pressure.
At this time, most patients complained of severe wrist pain, and a visual analog scale (vas) was supplied for each patient on which they marked the point that represented their perception of their current state.
The stenosis was too difficult to successfully widen and subsequent angiography showed evidence of >30% residual stenosis; therefore, the treatment standard was not met.
A vascutrak balloon was used to complete the procedure.
At follow up, reoccurrence of occlusion and restenosis were reported.
Re intervention was performed for these cases in the form of - surgical excision, reconstruction of a new fistula and recanalization.
One case of a brachial artery pseudoaneurysm complication occurred in the perioperative period.
Conclusion: the use of vascutrak balloon catheter to treat autogenous avf dysfunction resistant to conventional balloon angioplasty appears to be safe and effective, although further, large randomized controlled trials are necessary.
