Recanalization of a chronic occlusion flow-diverter device in a patient with a paraclinoid giant aneurysm recurrence. Clinical observation.

Paraclinoid internal carotid artery (ICA) aneurysms are associated with a high mortality rate, which gradually increases without intervention. Surgical clipping or coiling of large aneurysms with inadequate neck and adductor artery expansion will not guarantee a successful outcome. Carotid surgical trapping or endovascular occlusion of the adductor artery can help to isolate the aneurysm from circulation, but it comes at the expense of sacrificing a major blood vessel responsible for significant cerebral perfusion.

[Treatment of acute tandem occlusion of arteries of anterior cerebral circulation without emergency stenting].

Unlabelled: The article deals with problems of endovascular treatment of acute tandem and isolated occlusions of arteries of the anterior cerebral circulation, as well as the problem of reocclusions and new occlusions of these target arteries in the early postoperative period after thrombectomy.

Purpose: To determine the effect of reocclusions and new, previously not identified occlusions of the carotid artery and middle cerebral artery after cerebral thrombectomy on the outcomes of ischaemic stroke, as well as to substantiate feasibility of endovascular policy without simultaneous carotid stenting in thrombectomy in case of tandem occlusions of arteries of the anterior cerebral circulation.

Patients And Methods: We studied the results of endovascular treatment of 52 patients with acute ischaemic stroke, including 26 patients with combined occlusions of the internal carotid and middle cerebral arteries (group 1) and 26 patients with isolated occlusion of the M1 segment of the middle cerebral artery or its equivalent (group 2).
