Article Synopsis
- * The study analyzed 139,852 acute ischemic stroke patients in Texas from 2016-2019, revealing that various factors, like age, race, and insurance status, influence the likelihood of receiving critical stroke treatments.
- * Results showed that older adults, Black and Hispanic patients, and those from rural areas were less likely to receive thrombolysis and thrombectomy, highlighting disparities in acute stroke care associated with SDOH.
Article Synopsis
- The study focused on creating a deep learning algorithm to detect and pinpoint occlusions in cerebral DSA images, which is crucial for endovascular thrombectomy.
- Researchers collected DSA images from 188 patients, with a specific focus on those with occlusions in critical artery segments, to train and test the algorithm.
- The results showed the model achieved high specificity (0.95) and fairly good sensitivity (0.76), with promising performance in localizing large-vessel occlusions, suggesting more extensive data could boost its accuracy even further.
Background: Recently, the angled-tip Zoom aspiration catheters were introduced. The tip is designed to improve suction force for clot retrieval. We evaluated the possibility of reducing procedure costs when using angled-tip catheters and compared the safety and angiographic effectiveness of angled-tip versus straight-tip catheters.

- A case study details the successful use of Penumbra's Indigo Aspiration System for endovascular thrombectomy in a patient with cerebral venous sinus thrombosis and hemorrhagic infarct.
- The patient, a 30-year-old woman, presented with seizures and neurological deficits due to a significant blockage in her venous system, prompting the use of mechanical thrombectomy alongside anticoagulation therapy.
- The intervention led to a successful recanalization of the affected sinuses and an excellent recovery outcome, highlighting the effectiveness of this minimally invasive device in treating complicated venous thrombosis.
Background: Multiple studies have attempted to determine predictors of poor clinical outcomes in cerebral venous thrombosis (CVT). Fewer studies target to identify predictors of poor response to anticoagulation therapy in CVT.
Objective: We aimed to determine the predictors of poor clinical response to therapeutic anticoagulation in patients with acute CVT.
