Key result
Transradial approach links to a thyrocervical trunk pseudoaneurysm successfully treated with Onyx 18 embolization.
Why the study?
Thyrocervical trunk pseudoaneurysm formation is a rare complication of the transradial approach that presents variably and requires swift diagnosis and treatment.
Case Report (n=1)
Highlights a rare but potentially severe complication (thyrocervical trunk pseudoaneurysm) of the transradial approach requiring swift diagnosis and embolization.
Single-case report of abdominal/chest symptoms after uneventful transradial flow diversion; leaves open true complication rates and surveillance needs.
The transradial approach has gained popularity in the neuroendovascular field after several studies proved its low rate of hemorrhagic and vascular-related complications in both diagnostic and therapeutic procedures. This is a case of a patient who presented for flow diversion treatment of an incidental left carotid ophthalmic aneurysm. The procedure was uneventful. Post-operatively, the patient's neurological exam and vital signs were normal, however the patient complained of abdominal and chest pain that worsened when lying down and improved when sitting up. Radiologic diagnosis confirmed the presence of a thyrocervical trunk pseudoaneurysm which was completely obliterated with Onyx 18 embolization. Thyrocervical trunk pseudoaneurysm formation is a rare complication of the transradial approach. Shedding the light on these entities is essential as symptoms vary in severity and presentation and necessitate swift diagnosis and treatment.

Naamani et al. (2023) conducted a case report in Incidental left carotid ophthalmic aneurysm (n=1). Transradial approach was evaluated on Thyrocervical trunk pseudoaneurysm formation. The transradial approach for flow diversion treatment was complicated by a thyrocervical trunk pseudoaneurysm, which was successfully treated with Onyx 18 embolization.
