Complications - PTA of a left subclavian artery stenosis (balloon angioplasty)

Dissection

→ Bridging with stent or open correction (e.g., bypass)

Embolization

→ if relevant aspiration embolectomy or open embolectomy using balloon catheter

Vessel occlusion after dilatation

→ open correction (usually bypass required)

Hematoma, Secondary Bleeding Transfemoral Access/Puncture Site

→ Hematomas mostly self-limiting, surgical intervention rarely required (revision, vessel suture)

Pseudoaneurysm

→ Percutaneous sealing with fibrin, open revision in case of failure

AV Fistula

→ Embolization in case of long fistula channel, otherwise open revision

Occlusion of the Reconstruction

→ Change of procedure, if necessary bypass
