Complications - Percutaneous transluminal angioplasty and stenting of the right internal carotid artery in recurrent stenosis– Vascular surgery

Access problems

• If inguinal puncture not possible -> switch to opposite side; if this too fails -> continue with contralateral arm

Stent misplacement

• Overstenting or converting to open surgery, depending on the specific situation.

Carotid dissection

• Extend stenting

Carotid occlusion

• Emergency conversion to open surgery

Vascular spasms

• Triggered by intraoperative manipulations or guidewire movements
• Usually transient, but may also result in intermittent occlusion of the vessel with secondary stasis and thrombus formation
