ABSTRACT
Introduction Chronic subdural hematoma (cSDH) results from neovascularization of the subdural capsular membrane and embolization of the Middle Meningeal Artery (MMA) helps inhibit the same and prevent recurrence. Materials and methods We retrospectively reviewed the endovascular management for chronic SDH in 29 patients between 2018 to 2022. The parameters analyzed were clinical history, radiologic imaging findings, procedure details, and angiographic and clinical outcomes. Results Twenty-nine MMA embolization procedures were done. Follow-up MRI or CT done in 28 subjects, showed complete resolution in 25 patients and a significant reduction in bilateral SDH in three patients. One patient died due to renal failure and aspiration pneumonia-related complications. Ninety days mRS (modified Rankin scale) was 0 in 25 patients (86%), one in two patients, and two in one patient. Conclusions MMA embolization for chronic SDH is a feasible, safe, and effective technique in patients with chronic and recurrent SDH.
ABSTRACT
Background: Stroke related to cerebral venous thrombosis (CVT) is uncommon, with untoward lethal outcomes. Systemic anticoagulation is the treatment of choice. However, some patients can be resistant to this treatment. Endovascular management with thrombolysis and mechanical thrombectomy can be a viable option in such cases. Material and methods: We retrospectively reviewed the endovascular management used for CVT in 8 patients who failed to respond to standard anticoagulation therapy between December 2017 and December 2022 in our institute. Clinical profile, imaging parameters, endovascular procedure details, and outcomes in terms of angiographic findings and clinical follow-up were analysed. Results: In this period, a total of 8 patients underwent mechanical thrombectomy. The procedure was successful in all cases (8/8 = 100%), and 50% of them showed near total/complete recanalization; Perforation of the cortical veins was noted in 2 cases (~25%). Among the 8 patients, one died (1/8 = 12.5%) due to cardiac aetiology; the remaining 7 patients (87.5%) showed good clinical outcome with a modified Rankin Scale score 0 to 2. Conclusion: Catheter-directed thrombolysis with mechanical thromboaspiration is a safe and effective treatment for cerebral venous sinus thrombosis not responding to anticoagulation.
