The primary outcome was technical success, defined as the access catheter reaching its target vessel.

We report here our early experience in 30 mechanical thrombectomy cases.Materials and MethodsWe analyzed a prospectively maintained database of the senior authors to identify cases utilizing a 0.035' macrowire with 0.035' aspiration catheters for mechanical thrombectomy.ResultsThirty consecutive cases were identified. Seventeen (57%) patients were female with an average age of 75.3 ± 2.2 years (range 55-97). Average presenting NIHSS was 13.0 ± 1.7.

Endovascular treatment decisions were made at the discretion of neurointerventionalists. Clinical and angiographic data were collected, including Barrow CCF classification and treatment outcomes.ResultsPatients managed conservatively (<i>n</i> = 17) had longer symptom duration (165 vs 42 days) and more indirect CCF (100% vs 68%) compared to those treated with endovascular embolization (<i>n</i> = 67). High-risk clinical symptoms, including proptosis, diplopia, decreased visual acuity, and chemosis, were more common in the embolization group. Cortical venous reflux and ophthalmic venous reflux were more prevalent in the embolization group (39% and 91%, respectively).

Considering advanced techniques and device technology, we undertook an updated systematic review and meta-analysis to evaluate clinical and radiographic outcomes for treating CVST.MethodsWe searched PubMed and EMBASE for studies describing CVST patients treated with EVT. Presenting symptoms, procedural details, and clinical and radiographic outcomes were analyzed.

Data on demographics, preprocedural variables, radiographic features, procedural techniques, intra/postoperative events, and length of stay (LOS) were collected. Multivariable analysis was performed to identify patients requiring NCU-level care post-treatment.

In our subanalysis, 47 patients demonstrated NCU needs: 24 with intraoperative indications, 18 with postoperative indications, and five with both. Of the 23 with postoperative indications, 20 were identified within six hours, while three were identified within six to 24 h.
