This was a huge advance for stroke care, but we needed more. The U.S. Food and Drug Administration recently announced the recall of Penumbra Jet 7 Xtra Flex catheters because they may pose a risk of serious injury.The FDA has received over 200 medical device reports associated with the devices, including deaths, serious injuries, and malfunctions. Longer thrombectomy procedure times are associated with worse outcomes in acute ischemic stroke patients, a new study shows. The sooner the thrombectomy can be performed, the higher the chances are of restoring normal function.

Thrombectomy can treat the most severe cases of stroke – where the blood clot has blocked supply to an organ. The key difference between the two derives from where the clot is formed. Thrombectomy is only effective at treating ischaemic strokes caused by a blood clot in a large artery in the brain. An embolus is any piece of the clot that breaks off and travels through the bloodstream until it lodges itself into a blood vessel that is too small to pass through.

A clot that breaks free and travels to the lungs can cause a pulmonary embolism. Previous endovascular interventions were unable to remove clots quickly and safely enough. Recovery will vary widely and will depend on individual health and conditions, and a thrombectomy will not prevent the chance of another blood clot forming again. For smaller blood clots, the medication is very effective to break them up and move them through the arteries. Blood clots can disrupt the normal flow of blood to a part of the body, causing life-threatening conditions such as pulmonary embolism or an acute stroke.

The trial had 3 broad aims: (1) to gain greater experience with the Merci Retriever first-generation devices (X5 and X6) in patients ineligible for IV tPA, supplementing the data … In order to maneuver the catheter to the exact location, the surgeon will use a specialized X-ray to monitor placement of the catheter. That was basically unheard of before mechanical thrombectomy. In the past, a clot-busting medication called tissue plasminogen activator (tPA) had been the only approved treatment for this kind of stroke since its approval by the Food and Drug Administration in 1995. While both blockages are similar, the distinction between the two types can determine how a blood vessel handles the normal return of blood flow. Once removed, blood supply is restored and the patient is monitored for improvement. The retriever grabs the blood clot, and we remove both the retriever and the trapped clot. thrombectomy procedure? After administering tPA, stroke physicians use advanced neuro-imaging to evaluate the patient’s brain. The procedure involves inserting a catheter into an artery, often in the groin.

A stent-retriever is then slid into the catheter, which traps and encases the blood clot, allowing the surgeon to remove both the stent and the blockage from the blood vessel at the same time.
