Endovascular Treatment of Acute Ischemic Stroke Using the Stent Retriever-Assisted Vacuum-Locked Extraction Technique

Begin with an acute ischemic stroke patient with a large vessel occlusion in their brain.

Sedate the patient and place a sterile drape to prepare for endovascular treatment or EVT.

Shave and disinfect the patient's groin area.

Use the stent retriever-assisted vacuum-locked extraction or SAVE technique for EVT.

To perform SAVE, expose the femoral artery, a large blood vessel in the thigh, and puncture it using a needle.

Introduce a guiding sheath through the femoral artery to reach the brain blood vessel containing the clot.

Then, insert a catheter containing a stent retriever.

As the catheter is pulled out, the stent opens up, securing the clot.

The stent with the clot is then extracted with the help of suction from a vacuum pump.

Perform an angiogram to confirm successful reperfusion of the blood vessel.

Prepare the patient for the EVT together with the neuroradiological technician. Have the neuroradiological technician set up the material required for the EVT. Shave and disinfect the patient's groin with skin antiseptic, and place sterile drapes to ensure aseptic conditions for the EVT.

Induce sedation with ketamine in combination with propofol intravenously, and maintain a continuous infu
