Mechanical thrombolysis in ischemic stroke attributable to basilar artery occlusion as first-line treatment.

BACKGROUND AND PURPOSE: To report results of mechanical disruption or retrieval of thrombus as first-line treatment in patients with stroke attributable to occlusion of the basilar artery, in particular regarding efficiency and safety. METHODS: In 12 consecutive patients with acute stroke attributable to basilar occlusion, mechanical disruption or thrombus retrieval using various loop-shaped tools was tried before eventually starting local intra-arterial thrombolysis with recombinant tissue plasminogen activator (r-tPA). Main inclusion criteria were: National Institutes of Health Stroke Scale score >8 or Glasgow Coma Scale score <12; onset or worsening of symptoms <8 hours; no hemorrhages or large hypodensities on computed tomography scan; and occlusion of the basilar artery matching clinical symptoms. Efficiency included recanalization, procedure time, and r-tPA dose; safety was defined as rate of procedure-related complications. Outcome was evaluated at 3 months. RESULTS: Mechanical recanalization was successful in 6 patients. A single brain infarction, possibly attributable to distal embolization, occurred. Three patients had good outcomes. In 5 of 6 remaining patients, the artery was recanalized using r-tPA. A single asymptomatic hemorrhage occurred; 3 patients had good outcomes. Procedure time and r-tPA were significantly less in patients with successful mechanical thrombolysis (43.33 minutes and 13.33 mg versus 112.33 minutes and 55.83 mg, respectively). CONCLUSIONS: Mechanical recanalization was effective in half of the patients and at least as safe as local intra-arterial thrombolysis. It allowed to save r-tPA and time. Although the low success rate remains a limit, the excellent and quick anatomical recanalization obtained after successful procedures makes this approach promising.

Clinical picture of patients with cerebral venous thrombosis and patterns of dural sinus involvement.

BACKGROUND/OBJECTIVES: Cerebral venous thrombosis may cause focal brain lesions or an isolated intracranial hypertension without focal signs. We investigated whether these different clinical pictures correspond to different patterns of dural sinus thrombosis. METHODS: Forty-eight patients with cerebral venous thrombosis were classified in 2 groups based on the clinical and neuroradiological picture at admission: one group had clinical signs of intracranial hypertension, without focal neurological signs; the other group had focal neurological signs. The extension of thrombosis in dural sinuses was compared between the groups. RESULTS: The amount of thrombosed sinuses was significantly different in the two groups, the involvement of the dural sinuses being greater in patients with isolated intracranial hypertension. CONCLUSIONS: The clinical picture of cerebral venous thrombosis is related to the pattern of dural sinus involvement. The presence of isolated intracranial hypertension is more frequent in patients with a more extended thrombosis of the dural sinuses.
