Modified Rankin Scale (mRS) scores at 90 days post-thrombectomy for ischemic stroke (left). Patient outcomes have improved as experience and clinical volume have increased. UAB’s average of 56% of patients with a 90- day mRS score ≤2 is higher than the 45-49% reported in recent clinical trials (DAWN, DEFUSE 3). MODIFIED RANKIN SCALE (MRS) SCORES AT 90 DAYS POST- THROMBECTOMY PERCENT OF PATIENTS WITH TICI 2B OR HIGHER FOLLOWING IA BY MONTH Percentage of thrombectomy patients achieving a Thrombolysis in Cerebral Infarction (TICI) score of 2b or 3, which represents reperfusion of more than 50% of the affected territory (left). We actively follow our outcomes every quarter, which are demonstrated here for the last 15 months. Our reperfusion rates at 88% are better than the 76-84% reported in recent clinical trials (DAWN, DEFUSE 3). 150 AVERAGE TIMES FROM ARRIVAL AT THE HOSPITAL TO GROIN PUNCTURE IN PATIENTS UNDERGOING THROMBECTOMY 120 90 60 118 126 130 122 115 100 117 96 109 91 91 98 107 105 104 90 92 76 Average times from arrival at the hospital to groin puncture in patients undergoing thrombectomy is a critical determinant of success in acute treatment of stroke via mechanical thrombectomy. Our door-to-puncture times have continued to improve over time and are consistently reaching the established goal of under 90 minutes, according to best practices. uabmedicine.org 11
