First in man use of a Drug eluting Balloon for treatment of intracranial Stenosis

WITH ANGIOGRAPHIC FOLLOW-UP AFTER 5 MONTHS

Symptomatic intracranial stenoses have a high risk for a recurrent stroke if treated medically. Although angioplasty and stent placement are proposed treatment options, data shows a poor long-term outcome.Mortality rate when untreated is more than 20% in a period of 24 months.

Prof. Juergen Reul of Beta Klinik, Bonn, Germany, used successfully and at the first time in the world the Elutax Balloon catheter in a case of triple A. basilaris stenosis. The contra lateral artery was already occluded.

Before treatment:

Due to the triple-lesions anatomy a stent placement was not the first option, as the tortuosity of the vessel could jeopardize the successful placement.

During Intervention of Elutax:

After treatment with Elutax:

The triple restenosis is resolved and the blood flow is restored successfully.

Angiographic Control after 5 month:

The severe triple stenosis shows no sign of restenosis.

Patient Monitoring with Magnetic Resonance:

Severe stenosis could be detected by Magnetic Resonance

Before intervention:

Control after 6 Months after Elutax Treatment:

Background:

Elutax is developed especially for small vessels. The balloon is coated with 2 microgram/mm² pure Paclitaxel. As there is no stent mounted on the balloon, the pushability and the positioning of the device are facilitated compared to a balloon catheter with a stent.

The main cause of stenotic lesions is caused by neointimal cell hyperplasia. Local administration of lipophilic paclitaxel compounds inhibits the proliferation of such cells for a long period.
