Abstract W P8: "Double Trouble": Endovascular Treatment of Tandem Arterial Occlusions in Acute Ischemic Stroke
Background: Tandem extracranial/intracranial arterial occlusions in acute stroke present treatment challenges both due to suboptimal response to systemic intravenous thrombolysis as well as complex endovascular approach. We report our experience in treating this cohort of acute stroke patients with the analysis of angiographic and clinical outcomes
Materials and Methods: We retrospectively reviewed clinical and imaging data of all consecutive acute stroke patients with proximal intracranial arterial occlusion and additional extracranial occlusion/critical stenosis, treated with endovascular techniques between February 2011 and February 2014 at two hospitals. We analyzed patients’ demographics, clinical presentation, treatment strategies, time to recanalization, imaging and clinical outcomes.
Results: A total of 66 patients were included. The mean NIHSS on presentation was 19. Extracranial carotid with concomitant intracranial anterior circulation occlusions were present in 95% of the patients (63/66), while 5% (3/66) had tandem vertebrobasilar occlusions. 41% of the patients (27/66) received intravenous rt-PA. With regards to endovascular treatment, in 70% of the cases (46/66), extracranial lesion was treated with a stent placement. Stentrievers were used in 50% (33/66) of the patients for intracranial thrombectomy. Thrombolysis in Cerebral Infarction (TICI) >= 2B reperfusion was achieved in 77% of all the patients (51/66) and in 97% (32/33) of the stentriever patients. Good clinical outcome at 90 days (mRS<=2) was seen in 42% of the patients. Symptomatic intracerebral hemorrhage (PH-2)occurred in 9% (6/66) of the patients.
Conclusions: Endovascular treatment of tandem arterial occlusions in acute ischemic stroke is relatively safe, feasible, and may yield excellent angiographic and good clinical outcomes.
