Sudden symptomatic occlusions of the proximal internal carotid artery (ICA) resulting in severe middle cerebral artery (MCA) ischemia and stroke are usually not accessible by rt-PA thrombolysis and the prognosis is usually very poor. Mechanical recanalization of the proximal ICA combined with intravenous and intra-arterial thrombolysis was therefore used as a rescue procedure.


Ten patients (9 men, 1 woman; mean age 56.1 years) were treated with emergency recanalization of the proximal carotid artery by using stents and/or balloon angioplasty as a rescue procedure. Three patients showed dissection, and 7 had atherothrombotic occlusions. Nine of 10 presented with an initial modified Rankin Scale (mRS) of 5, the remaining patient with mRS 4 (average NIHSS 21.4). After sonographic confirmation of ICA with associated MCA/distal ICA occlusion and bridging with rt-PA (without abciximab) an emergency angiography was performed with subsequent mechanical recanalization by percutaneous transluminal angioplasty (PTA) (n = 1) or primary stenting (n = 9) using self-expanding stents. Distal protection was used in 1 of 10 patients.


Recanalization of the proximal ICA was achieved in all. At least partial recanalization of the intracerebral arteries was achieved in all, and complete recanalization in 5. In 4 of 10 patients limited hemorrhage was detected during CT controls. Major complications included 2 patients who had to undergo hemicraniectomy. One patient died from malignant infarction. At the time of discharge from the stroke unit 9 of 10 patients had improved markedly, 5 patients having an mRS of ≤2, and 3 patients a mRS of 3. At control after a mean of 20 weeks, 7 of 8 (88%) patients had a mRS ≤2, and 1 a mRS of 3.


Primary mechanical recanalization of ICA occlusions by stent and PTA combined with fibrinolysis and/or GPIIb/IIIa-receptor antagonists seems to be feasible to improve patient outcome significantly.
