A catheter was directed stereotactically or manually into the ICH through a burr hole under CT guidance. Hematoma aspiration was followed by instillation of urokinase (5 000 to 10 000 IU). This was repeated every 6 to 8 hours at bedside, with interval CT imaging, until the ICH volume diminished to &lt;25 mL, less than half of its initial volume, or after a maximum of 10 aspirations\/instillations.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Results<\/jats:italic>\n            \u2014Mean age was 69 years (range 55 to 82 years). Median initial GCS was 12 (range 5 to 14). There were 7 ganglionic and 5 lobar ICH, and baseline hematoma size ranged 29 to 70 mL (mean 46 mL). Final ICH volume ranged from 14 to 51 mL (mean 21 mL), with ICH volume reduction by an average of 57% (range 38% to 70%). One patient (8.3%) suffered hematoma expansion during the procedure. At 6 months after the procedure, 3 patients (25%) had achieved a good recovery (Glasgow Outcome Scale [GOS] score of 5), 5 patients (42%) were dependent (GOS 3), and 1 (8.3%) remained vegetative (GOS 2). Three patients (25%) died in hospital (1 from cardiac arrhythmia and 2 from respiratory failure).\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            \u2014CT-guided thrombolysis and aspiration appears safe and effective in the reduction of ICH volume. Further studies are needed to assess optimal thrombolytic dosage and must include controlled comparisons of mortality, disability outcome, time until convalescence, and cost of care in treated and untreated patients.\n          <\/jats:p>","DOI":"10.1161\/01.str.31.4.834","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:10:52Z","timestamp":1308341452000},"page":"834-840","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":118,"title":["Stereotactic Computed Tomographic\u2013Guided Aspiration and Thrombolysis of Intracerebral Hematoma"],"prefix":"10.1161","volume":"31","author":[{"given":"Jose M.","family":"Montes","sequence":"first","affiliation":[{"name":"From the Neurovascular Surgery Program, Department of Neurosurgery (J.M.M., J.H.W., I.A.A.), and the Stroke Program, Department of Neurology (P.B.F.), Yale University School of Medicine, New Haven, Conn."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John H.","family":"Wong","sequence":"additional","affiliation":[{"name":"From the Neurovascular Surgery Program, Department of Neurosurgery (J.M.M., J.H.W., I.A.A.), and the Stroke Program, Department of Neurology (P.B.F.), Yale University School of Medicine, New Haven, Conn."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre B.","family":"Fayad","sequence":"additional","affiliation":[{"name":"From the Neurovascular Surgery Program, Department of Neurosurgery (J.M.M., J.H.W., I.A.A.), and the Stroke Program, Department of Neurology (P.B.F.), Yale University School of Medicine, New Haven, Conn."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Issam A.","family":"Awad","sequence":"additional","affiliation":[{"name":"From the Neurovascular Surgery Program, Department of Neurosurgery (J.M.M., J.H.W., I.A.A.), and the Stroke Program, Department of Neurology (P.B.F.), Yale University School of Medicine, New Haven, Conn."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.51.3_Suppl_3.S69"},{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1040904"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/str.27.7.1215"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/str.29.9.1917"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/str.28.11.2126"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.1997.tb00078.x"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1990.00530100071015"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1989.70.5.0755"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(61)90353-1"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.51.5.1359"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1989.70.4.0530"},{"key":"e_1_3_1_12_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1984.61.3.0440"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.3949\/ccjm.60.4.321"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199502000-00012"},{"key":"e_1_3_1_15_2","first-page":"962","volume":"96","year":"1997","unstructured":"Tzaan WC, Lee ST, Lui TN.
