Comparative Analysis for Mechanical Thrombectomy-Stent Retriever VS Aspiration Catheters

Treatment Option

Overview

Advantage

Stent Retrieval Thrombectomy

Through microcatheter technology, the stent thrombectomy device reaches the intracranial artery along the artery of the lower extremity through the arterial channel in the body, and the thrombus clot retrieval device at the front of the catheter actively captures the thrombus blocking the blood vessel to restore the patients of the blood vessel.

• Wide range of indications;

• low risk of bleeding;

• Higher recanalization rates;

• Suitable for old blood clots.

Direct Aspiration Ctheter Thrombectomy

Through the femoral artery, a large inner diameter aspiration catheter is pushed to the proximal end of the blocked cerebral artery with the help of a guide wire, and a syringe is manually operated to form sufficient negative pressure and suction force in the catheter to suck out the thrombus.

• Simple technical operation;

• Short canalization time;

• low risk of bleeding;

• Fewer distal embolisms.

Stent Retrieval Thrombectomy+Aspiration Ctheter Thrombectomy

Through contact suction, maintain suction negative pressure, pull the stent retriever together with the thrombus into the intermediate catheter, when the stent retrieval pulls the thrombus to the Y-shaped connection valve, the aspiration catheter will quickly return blood under negative pressure suction, thereby realizing blood vessel recanalization .

• Stent retriever and aspiration catheter work synergistically to reduce recanalization time;

• Low risk of mechanical injury and bleeding;

• For patients with tortuous pathways, the combination of intermediate catheter tubes can reduce the difficulty of stent placement.
