• The earlier the thrombectomy is performed after the onset of symptoms, the better the outcomes tend to be. For example, patients who undergo thrombectomy within 6 hours of symptom onset generally have better recovery rates compared to those treated later. 

•  The 30-day mortality rate is approximately 29% in some studies, indicating that survival is significantly enhanced through timely intervention. 

• Successful revascularization rates (TICI grades 2b to 3) after thrombectomy can be around 88.5%, contributing to sharp reductions in disability. 

• Ongoing studies highlight that nearly 42% of patients achieve functional independence (defined as a modified Rankin Scale score of 0-2) at 90 days post-procedure. 

What are the chances of a second surgery?

• The incidence of reocclusion of the same major vessel after a successful thrombectomy is quite low, typically around 2.5% to 5% depending on the studies. 

• Overall, while the requirement for a second surgery post-thrombectomy is relatively low, it is not insignificant. The exact chances can vary based on individual patient circumstances, timing of intervention, and successful recanalization rates.
