Local thrombolysis for patients of severe cerebral venous sinus thrombosis during puerperium

ObjectiveTo explore and evaluate the efficacy of intrasinus thrombolysis (IST) in patients with cerebral venous sinus thrombosis (CVST) during postpartum period.Methods11 patients during postpartum period with CVST who received IST during July 2007–November 2011 were included. Urokinase was infused into the sinuses via a microcatheter. Magnetic resonance venography (MRV) was performed to assess the recanalization of venous sinuses.ResultsBefore discharge, the intracranial pressure in 11 patients was under 200 mmH2O. MRV confirmed that venous sinus of 9 patients were smooth. The cortex venous and deep venous recovered to normal. Venous sinus of 2 patients recanalized partly, and cortex venous and deep venous had compensation. 9 patients had good outcome and 2 patients had only mild deficits.ConclusionIntrasinus thrombolysis is safe and effective in patients with severe cerebral venous sinus thrombosis during postpartum period.
