Analysis of the related factors of "invalid recanalization" of stent thrombectomy in acute anterior great vessel occlusion

ObjectiveTo investigate the related factors of "ineffective recanalization" after stent thrombectomy in acute anterior great vessel occlusion.

MethodsThe responsible vessels in 56 acute anterior great vessel occlusion patients were successfully recanalized after the stent was removed, and the patients were divided into the valid recanalization group and invalid recanalization group.The related factors in two groups were analyzed.

ResultsThe differences of the onset to recanalization time(OTR), pnucture to recanalization time(PTR), ASPECT score and number of pulling stent between two groups were statistically significant(P < 0.05 to P < 0.01).Shortening OTR could significantly reduce the incidence of ineffective recanalization.After the bolt in the patients with ASPECT ≤ 7 scores were removed, the ineffective rate of which was significantly higher than that in patients with ASPECT >7 scores.The effect of number of pulling stent on the invalid recanalization rate was significant, the invalid recanalization rate in patients with pulling stent ≥ 5 times was significantly higher than that in patients with pulling stent < 5 times.The differences of the number of pulling stent and PTR between two groups were statistically significant(P < 0.01).

ConclusionsShortening the treatment process of ischemic cerebrovascular disease before and in hospital, opening up green channel, skillfully taking stent technique to reduce the times of pulling stent and shortening the time of recanalization of blood vessel can reduce the invalid recanalization.
