ABSTRACT
Objective:To investigate the efficacy and safety of endovascular recanalization treatment for acute vertebral basilar artery occlusion (AVBAO) underlying intracranial atherosclerotic disease (ICAD) using a balloon-mounted stent.Methods:A total of 16 cases of consecutive AVBAO patients who underwent endovascular treatment with the balloon-mounted stent within 24 h after onset were retrospectively enrolled in Henan Provincial People′s Hospital from February 2017 to August 2019. And the recanalization rate, operation-related complications, symptomatic intracranial hemorrhage, the improvement of 1 week National Institutes of Health Stroke Scale (NIHSS) score and 3 months modified Rankin Scale (mRS) after treatment were recorded.Results:In all of the 16 patients, 4 patients underwent direct stenting angioplasty, 12 patients received salvage stenting. Stent placement was successful in all 16 patients. Balloon-mounted stent were implanted in basilar artery of 4 cases, in intracranial segment of vertebral artery of 8 cases, and in origination segment of vertebral artery of 4 cases. Recanalization was successful (thrombolysis in cerebral infarction grade 2b and 3) in 15 patients. The time between arterial puncture and recanalization was 79.0 (72.3, 109.3) min. One patient experienced distal thrombosis during surgery. Two patients suffered symptomatic intracranial hemorrhage within 48 h after surgery. The scores of the NIHSS were improved more than 4 points at 1 week after operation in 8 patients. At 3 months follow-up, 9 patients had a good outcome (mRS 0-3 points) and 4 patients died.Conclusion:Selective stenting angioplasty treatment with a balloon-mounted stent seems to be feasible and safe for AVBAO patients underlying ICAD.
ABSTRACT
Objective Applying color Doppler ultrasonic test on the first dorsal metatarsal arteries,to acquire relevant Doppler bloodstream parameters,and in the end,to explore the clinical value of this approach.Methods Applying GE-LOGIQ-400 color Doppler high-frequency ultrasonic test on the first dorsal metatarsal arteries of 100 diabetes patients,contrasting to those of 60 normal persons,observing the origination,trend,smooth of bloodstream,angioplerosis Status,analyzing bloodstream spectrum(including the interior diameter of blood vessel,spectrum status,bloodstream speed,drag index,erc.),and contrasting the resuits.Results The first dorsal metatarsal arteries of diabetes patients have narrower interior diameter,faster bloodstream speed,higher drag index than those of non-diabetes patients.Conclusion The high-frequency color Doppler ultrasonography can provide objective clinical evidence on the test of the first dorsal metatarsal arteries diseases.
