| Abstract | BACKGROUND AND PURPOSE: Intravenous tissue-type plasminogen activator (IV tPA) frequently fails to recanalize proximal middle cerebral artery (MCA-M1) obstructions, preventing favorable outcomes. Only neurointerventional procedures prevail in these cases, but well-equipped centers remain scarce. A new therapeutic strategy consisting of a second IV thrombolysis with low-dose tenecteplase was applied. METHODS: Consecutive patients with an MCA-M1 occlusion that did not reopen at the end of IV tPA perfusion received IV tenecteplase (0.1 mg/kg). Partial or complete thrombolysis in myocardial infarction recanalization (Thrombolysis In Myocardial Infarction grade 2/3) and intracerebral hemorrhage were assessed by magnetic resonance aging approximately 24 hours later. Clinical outcomes at 3 months were evaluated with the modified Rankin score. RESULTS: Among 40 patients with MCA-M1 occlusions who received IV tPA, 13 were treated according to the protocol of sequential combined IV thrombolytics. Baseline National Institutes of Health Stroke Scale score was 15. At a mean of 16.8 hours after IV thrombolysis, the recanalization rate was 100% (2 with Thrombolysis In Myocardial Infarction grade 2, 11 with Thrombolysis In Myocardial Infarction grade 3). Intracerebral hemorrhage occurred in 4 of 13 (31%) patients, with no symptomatic hemorrhage. Good clinical outcomes (modified Rankin score = 0/1) were achieved in 9 of 13 (69%) patients. Functional outcomes were very similar to those of 13 patients with early IV-tPA recanalization. Among 4 patients treated as protocol violations, 1 presented with a lack of recanalization and a parenchymal hematoma type 2. CONCLUSIONS: For patients with MCA-M1 occlusions treated with IV tPA but without early recanalization, a second bolus of IV tenecteplase (0.1 mg/kg) may be a relatively safe, effective, and easy option in carefully selected cases, but additional studies are needed to confirm these findings. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
