The OPTION trial evaluated IV tenecteplase (0.25 mg/kg) in CT perfusion–selected non-LVO ischemic stroke patients treated 4.5–24 hours after last-known-well. Tenecteplase improved excellent 90-day outcomes (mRS 0–1) but increased symptomatic intracranial hemorrhage, with the benefit–harm balance sensitive to outcome and ...
The HAT and SEDAN scores help estimate symptomatic intracranial hemorrhage risk after stroke thrombolysis. This comparison reviews what each tool measures, when to use them, and the key limitations clinicians should know.
The cornerstone of acute ischemic stroke (AIS) management involves timely reperfusion of the ischemic brain tissue. Intravenous thrombolysis with alteplase has been the standard of care for AIS within 4.5 hours of symptom onset, based on pivotal trials such as ...
The American Heart Association and the European Stroke Organization have updated their guidelines to recommend TNK as an alternative to tPA in patients eligible for thrombolysis. TNK, a bioengineered variant of tPA, has some advantages, including its single-dose administration, fibrin ...
Background: Retinal artery occlusion (RAO) is a time-sensitive ophthalmic emergency that demands rapid diagnosis and intervention. Administration of intravenous tissue plasminogen activator (IVtPA) within 4.5 hours of symptom onset appears to be the most promising approach for improving visual outcomes, supported ...
