Abstract

Preliminary experience with distal radial artery (dRA) access for diagnostic cerebral angiography and some neurointerventional procedures has proved to be promising with good technical results and a reliable safety profile. Vascular access via the dRA may further improve minimally invasive treatment of intracranial aneurysms. Between July 2019 and June 2020 we identified 11 patients (9 females) with a mean age of 63.5 years who underwent WEB device placement for treatment of their intracranial aneurysm via the dRA approach. The mean aneurysm size (largest diameter) was 6.7 mm. One patient required conversion to femoral access due to severe brachial artery fibromuscular dysplasia. Placement of the WEB device was successful in all other cases via dRA approach. In all but one case, a low profile triaxial catheter system with the 6F Benchmark guide catheter (Penumbra) and 5F Sofia distal access catheter (Microvention) were used. No access related complications were observed. The combination of the intrasaccular WEB device and dRA access represents an ideal approach which offers operators a low risk vascular access and high procedural success by maintaining the ability to precisely place and manipulate the device using low-profile catheter systems. At the same time, this approach offers patients the most minimally invasive experience currently available for treatment of intracranial aneurysms with quick postprocedural recovery, minimal restrictions and low risk for access site complications.
