There are numerous different products on the market that can be used therapeutically but most of the current guidelines recom- mend the use of stent retrievers instead of other devices [2, 3]. In this case report we present our experiences with the Tigertriever (Rapid Medical, Yoqneam, Israel), a new stent retriever device with an adjustable design in the case of acute basilar artery occlusion. Case report A 70-year-old male suffering from a sudden onset of distur- bances of consciousness and vomiting was admitted to the emergency department of our institution. According to his relatives he was being treated with rivaroxaban due to atrial fibrillation. Diffusion-weighted magnetic resonance imag- ing (DW-MRI) showed acute ischemia in the left superior cerebellar artery (SCA) territory (Fig. 1) and magnetic reso- nance angiography (MRA) revealed occlusion of the basilar artery.

With the patient under general anesthe- sia a 6 F introducer was placed in the right femoral artery and a 6 F guiding catheter was advanced to the right verte- bral artery via a 0.035-inch guidewire. Contrast injections through the guiding catheter showed occlusion of the tip of the basilar artery (Fig. 2a). The occluded segment was bypassed with a Vasco 21 catheter (Balt, Montmorency, France) over a 0.014-inch Hybrid micro-guidewire (Balt, Montmorency, France) and the left posterior cerebral artery (PCA) was catheterized. A Tigertriever device was ad- Fig. 1 Diffusion-weighted magnetic resonance imaging shows acute ischemia in left superior cerebellar artery territory K
