Background and purpose |
Delayed radial artery occlusion (dRAO) is a frequent complication after transradial access (TRA) for neurointervention when using standard large guide catheters. The RIST 079 guide catheter (RIST GC) is the first catheter designed for TRA in neurointervention. We aimed to assess the rate of dRAO after intracranial aneurysm (IA) treatment using the RIST GC.
Methods |
Patients treated for an IA using TRA and the RIST GC between June 2021 and November 2022 were referred to a systematic US-doppler assessment of the radial artery patency at 3-month follow-up. Patients with and without dRAO were compared to identify risk factors.
Results |
Twenty-two patients were included in the analysis. At 3-months follow up, 6 patients (27.3 %) presented with dRAO. Four patients were asymptomatic and 2 experienced post-operative radial hematoma and wrist pain. There was a tendency towards younger age, longer procedure duration and higher rate of forearm hematoma in patients with dRAO. Navigation using the RIST GC was successful in 90.9 % of cases. Intracranial access failures and navigation complications were all related to left internal carotid artery navigation.
Conclusions |
At 3-month follow up, 27.3 % of patients treated for IA using TRA with the RIST GC presented dRAO.

Highlights |
• | Radial access offers fewer access site complications and improved patient comfort. |
• | Large guide catheter are asssociated with high rates of radial artery occlusion. |
• | The RIST 079 is specifically designed for radial access in neurointervention. |
• | Radial artery occlusion occurred in 25 % of patients at 3-month with the RIST 079. |
• | Patients’ selection and alternative strategies may reduce radial artery occlusion rate. |
