Medtronic has announced the first neurointerventional case in Europe with its Rist 6Fr radial access catheter, which recently received regulatory approval for use in European Union (EU) countries and other geographies accepting a CE mark.
According to Riitta Rautio (Turku University Hospital, Turku, Finland), who performed the first case, the 6Fr Rist “expands the number of patients [we can treat] and the variety of neurointerventions we can perform transradially”.
The case in question involved the treatment of a 79-year-old female patient with chronic subdural haematoma (SDH) via a middle meningeal artery (MMA) embolisation procedure. Rautio described the navigation of the 6Fr Rist device to the patient’s right external carotid artery (ECA) as “extremely smooth, trackable and stable”, with the distal MMA being accessed successfully, and Onyx 18 (Medtronic) being injected to embolise and treat their cSDH prior to radial artery closure with a compression band.
“I prefer radial access, especially for older patients, due to fewer femoral access site complications and early ambulation time,” Rautio said, also noting that this patient was discharged home the following day.
The “flexible and hydrophilic” nature of Rist enabled “easy” navigation to the anatomic position in the patient’s ECA, and excluded the need for a distal access catheter, in the case, Rautio added. She further stated that the distal end of the 6Fr Rist catheter is shorter than the 7Fr iteration of the device, resulting in better stability when working close to the aortic arch.
“With smaller devices, we make fewer complications,” Rautio concluded.
With its recent CE-mark approval, Medtronic’s Rist 6Fr radial access catheter joins the company’s Rist 7Fr radial access guide catheter and radial access selective catheter on the European market.
