This study aimed to compare the safety and efficacy of modified SPM with traditional SPM. Methods A total of 1454 consecutive patients who failed a chronic total occlusion percutaneous coronary intervention(CTO PCI) attempt and underwent SPM from January 2015 to December 2019 at our hospital were reviewed retrospectively. Fifty-four patients who underwent SPM finally were included in this study. We analyzed the outcomes of all the patients, and the primary endpoint was recanalization rate, which was defined as Thrombolysis in Myocardial Infarction(TIMI) grades 2-3 flow on angiography 30 to 90 days post-procedure. Results The baseline characteristics were similar between the two groups. In the follow-up, the recanalization rate was noticeably higher in the modified SPM group compared with the traditional SPM group(90.9% vs. 62.5%, P < 0.05). The proposed strategy in the modified group was more aggressive, including a larger balloon size(1.83 ± 0.30 vs. 2.48 ± 0.26 mm, P < 0.05) and longer subintimal angioplasty(0.59 ± 0.16 vs. 0.92 ± 0.12 mm, P < 0.05). Also, the common use of a Stingray balloon and guide catheter extension resulted in improvement of patients in the modified SMP group(12.5% vs. 100%, P < 0.05). Conclusion Modified SPM, which is associated with a high likelihood of successful recanalization, is an effective and safe CTO PCI bail out strategy.展开更多

The differences in vascular recanalization rate 24 h after treatment as well as serum levels of inflammatory mediators [interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-7 (IL-7), interleukin-17 (IL-17) and hypersensitive C-reactive protein (hs-CRP)], nerve injury markers [brain-derived neurotrophic factor (BDNF), neuron-specific enolase (NSE) and S100B protein (S100B)] and neurotransmitters [glutamate (Glu) and 5-hydroxytryptamine (5-HT)] before and after treatment were compared between the two groups of patients.Results: 24 h after treatment, the vascular recanalization rate of the observation group was higher than that of the control group (P<0.05). 24 h after treatment and 1 week after treatment, serum IL-1, IL-6, IL-7, IL-17 and hs-CRP levels in the observation group were lower than those in the control group;BDNF level was higher than that in the control group, while NSE and S100B levels were lower than those in the control group;Glu and 5-HT levels were lower than those in the control group (P<0.05). Conclusions: Mechanical thrombectomy combined with rt-PA thrombolysis can increase the early postoperative vascular recanalization rate in patients with acute cerebral infarction, and it also plays an active role in alleviating nerve injury.展开更多

The study included 65 patients with extracranial internal ca-rotid artery occlusion who underwent carotid endarterectomy, carotid endarterectomy combined with Fogarty catheter embolectomy, or hybrid surgery in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, China between January 2006 and December 2012. Prior to surgery, all patients underwent perfusion CT or xenon CT to evaluate the occlusion. The procedure for each patient was chosen according to digital subtraction angiography data. The carotid artery was successfully recanalized in 46 of 51 patients who underwent carotid endarterectomy, 9 of 10 patients who underwent carotid endarterectomy combined with Fogarty catheter embolectomy, and 3 of 4 patients who underwent hybrid surgery. In patients with symptomatic carotid artery occlusion, the carotid artery can be recanalized by choosing a treatment procedure based on imaging ex-amination findings.展开更多
