How is a mechanical thrombectomy performed?
Mechanical thrombectomy is type of minimally-invasive procedure in which an interventional radiologist uses specialized equipment to remove a clot from a patient’s artery. Using fluoroscopy, or continuous x-ray, the doctor guides instruments through the patient’s arteries to the clot, extracting the clot all at once.
Where is mechanical thrombectomy performed?
An endovascular specialist makes a small incision in your groin or wrist. Using real-time X-ray-guided imaging, we thread a catheter through an artery that leads to your neck and brain. Once we reach the clot, specialists insert a device (stent retriever) into the catheter and advance it past the blood clot.
How long does a mechanical thrombectomy take?
Prior studies have shown that extending the duration of mechanical thrombectomies past 60 minutes, and more recently past 35 minutes, decreases the chance a patient will show few-to-no neurological disabilities after 90 days and increases the chance of a postprocedural hemorrhage.
What happens during a thrombectomy?
During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.
How long is the recovery after a thrombectomy?
Walk around often and return to your activities as directed by your healthcare provider. Avoid strenuous activity for 3 weeks. Do not drive until your healthcare provider says it is okay. You may need to wait a week or longer before you can start driving again.
What is a serious potential complication of mechanical thrombectomy?
Well known complications of mechanical thrombectomy include intracerebral hemorrhage, emboli to new vascular territories, vessel dissection, vasospasm of the access vessel, and stent-related complications [2] .
Can you walk after thrombectomy?
Recovery From Venous Thrombectomy Venous thrombectomy is usually effective in removing blood clots. Patients have to walk and rest repeatedly for up to 6 hours after the surgery to assist in their vascular healing. Postsurgery, they can expect to wear compression stockings and be prescribed painkillers and antibiotics.
What is mechanical thrombectomy?
Mechanical thrombectomy is an emergency procedure used to remove a blood clot from a blood vessel (vein or artery). The procedure is usually done on arteries. Examples include hip and clavicle (collarbone) arteries. A clot can also be removed from a vein or artery in the brain to help prevent a stroke.
How many stroke patients does mechanical thrombectomy help each year?
That means mechanical thrombectomy could potentially help between 103,500 and 172,500 Americans each year. This procedure has been available to patients outside of clinical trials only since 2014, but it’s revolutionized stroke treatment in that time.
How is patient selection for mechanical thrombectomy guided by guidelines?
Patient selection for mechanical thrombectomy is guided in part by criteria used in recent trials and subsequent recommendations provided by stroke association guidelines. 11 Center-specific patient-selection criteria may be broader and depend on conversations between the vascular neurologist, neuro-interventionalist, and the patient and family.
How long does a thrombectomy surgery take?
Your procedure will vary depending on the type of thrombectomy you have. The surgery may last an hour or multiple hours depending on the location and extent of the blood clot. Anesthesia/sedation: You receive general anesthesia or sedation through a vein in your arm.
