Rescue Distal Thrombectomy for Stroke

(2BE3-PhaseII Trial)

This trial aims to determine if an additional procedure, rescue distal mechanical thrombectomy (a type of surgical procedure), can benefit people with small blocked arteries remaining after clearing a main artery during stroke treatment. It will compare two methods: performing this extra procedure or not taking additional action after the main treatment. The trial seeks to establish whether the additional procedure is safe and beneficial for better recovery and blood flow. People with a recent stroke, who have undergone the main treatment but still have small artery blockages, might be suitable candidates. As an unphased trial, this study offers participants the chance to contribute to important research that could enhance stroke recovery treatments.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that rescue distal mechanical thrombectomy, used after removing a main clot in stroke patients, is generally safe. One study found that this procedure, part of endovascular thrombectomy, reduced the risk of death within three months by 17% for patients with large vessel blockages. Another study noted that a similar procedure, rescue stent placement, carries a low risk of causing serious bleeding.

Researchers are excited about rescue distal thrombectomy because it offers a potential breakthrough for treating acute ischemic stroke with persistent distal occlusions. Unlike the standard treatment, which typically involves only proximal mechanical thrombectomy followed by conservative management, this approach targets the smaller, distal blood clots that remain. By addressing these smaller clots during the same procedure, the technique aims to improve overall blood flow to the brain, potentially leading to better recovery outcomes. This method could fill a critical gap in stroke care, providing an additional layer of intervention for those with complex vascular blockages.

Research has shown that endovascular thrombectomy, a procedure to remove blood clots from arteries, can reduce disability in some stroke patients. Studies have found that this procedure can lead to better recovery, with some patients experiencing significant improvement. For example, one study found that about 39.4% of patients who had clots removed from smaller arteries in the brain showed good recovery. This trial will compare two approaches: participants in one arm will receive conservative management without additional distal intervention, while those in another arm will undergo rescue distal mechanical thrombectomy to remove clots from smaller arteries. This suggests that removing clots from these smaller arteries might improve recovery after a stroke. However, more research is needed to confirm that this method is safe and effective overall.²³⁵⁶⁷
