Nitrogen monoxide vector of ultrasonic atomizing inhalation improves vertebro-basilar artery insufficiency Hemodynamic changes are detected by transcranial Doppler test

BACKGROUND： Latest researches at home and abroad indicate that glycerol trinitrate plays its function because it can metabolize into nitrogen monoxide （NO） in vivo. OBJECTIVE： To study the therapeutic effects of NO vector of ultrasonic atomizing inhalation on vertebro-basilar artery insufficiency （VBI） through transcranial Doppler （TCD） detection and serum NO content and indirect effect of TCD on cerebral blood flow changes. DESIGN： Randomized grouping and controlled clinical study. SETTING： Department of Neurology, the Fourth People＇s Hospital of Jinan. PARTICIPANTS： A total of 130 patients who were diagnosed as VBI were selected from Department of Neurology, the Fourth People＇s Hospital of Jinan from December 2001 to December 2005. The involved inpatients were checked by CT and MRI, and met the VBI diagnostic standard enacted by the Fourth National Academic Meeting of Cerebrovascular Disease in 1995. All patients and their relatives provided the confumed consent. They were randomly divided into low-dose treatment group （n =60）, high-lose treatment group （n =30） and control group （n =40）. METHODS： Patients in the low-dose and high-dose treatment groups were given ultrasonic atomizing inhalation of 3 mg and 5 mg glycerol trinitrate, respectively, for 20 minutes, once a day. In addition, ligustrazine and energy mixture were used once a day for three days in a course. Cases in the control group were only given ligustrazine and energy mixture. All selected cases accepted TCD, blood NO content was checked at the time of beginning, after the first time and after a period of treatment. According to the TCD test, VBI patients were divided into two groups （high-low flow velocity）. The vertebral artery （VA） and basal artery （BA） of left or right sides were detected by 2 Hz detector via occipital window. MAIN OUTCOME MEASURES： ①Blood flow velocity of systolic phase, blood flow velocity of diastole phase and vascular resistance in left and right VA and BA detected by using TCD before treatment, after treatment for one course; ②content of serum NO indirectly measured by using nitric acid disoxidation technique. RESULTS： All 130 VBI patients were involved in the final analysis. ①Changes of hemodynamic indexes： Systolic phase of VA and diastole phase of BA were higher in low-dose treatment group than that in the control group after first treatment, and there was significant difference （P 〈 0.05）; meanwhile, systolic phase and diastole phase of VA and systolic phase of BA were also higher in treatment group than that in the control group after one course （P 〈 0.05）. However, both systolic phase and diastole phase of VA and BA were lower in high-dose treatment group than that in the control group after first treatment and one course, and there was significant difference （P 〈 0.05）. ②Content of serum NO： After first treatment, there was no significant difference between low-dose treatment group and high-dose treatment group （P 〉 0.05）; but both groups were higher than control group, and there was significant difference （P 〈 0.05, 0.01）. CONCLUSION： NO vector of ultrasonic atomizing inhalation can improve VBI so as to improve cerebral blood-supply state.

Evaluation value of CTA for vertebrobasilar artery stenosis in patients with posterior circulation cerebral infarction and its correlation with serum biochemical indexes

Objective: To study the evaluation value of CTA for vertebrobasilar artery stenosis in patients with posterior circulation cerebral infarction and its correlation with serum biochemical indexes. Methods: A total of 148 patients who were treated in Maanshan Shiqiye Hospital between June 2014 and February 2017 due to vertebrobasilar artery stenosis were selected as the research subjects and divided into cerebral infarction group and transient ischemic attack (TIA) group according to the imageological examination. CTA was used to evaluate vertebrobasilar atherosclerotic plaque properties, and enzyme-linked immunosorbent assay kit was used to determine the levels of nerve injury markers, inflammatory response-related molecules and plaque property-related protease molecules. Results: The positive rate of posterior circulation plaque in cerebral infarction group was obviously higher than that in TIA group, and the positive rate of unstable plaque, fibrous plaque and calcified plaque were higher than those in TIA group;serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque, fibrous plaque and calcified plaque were all higher than those of TIA group;serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque and fibrous plaque were all higher than those of patients with calcified plaque, and serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque were all higher than those of patients with fibrous plaque. Conclusion: CTA can accurately assess the property of vertebrobasilar atherosclerotic plaque in patients with posterior circulation cerebral infarction and is closely related to the degree of nerve injury and the change of plaque property.

Low-molecular-weight dextran for optical coherence tomography may not be protective against kidney injury in patients with renal insufficiency

BACKGROUND Low-molecular-weight dextran(LMWD)is considered a safe alternative to contrast media for blood displacement during optical coherence tomography(OCT)imaging.AIM To investigate whether the use of LMWD for OCT is protective against kidney injury in patients with advanced renal insufficiency.METHODS In this retrospective cohort study,we identified 421 patients with advanced renal insufficiency(estimated glomerular filtration rate<45 mL/min/1.73 m2)who underwent coronary angiography or percutaneous coronary intervention;79 patients who used additional LMWD for OCT imaging(LMWD group)and 342 patients who used contrast medium exclusively(control group).We evaluated the differences between these two groups and performed a propensity score-matched subgroup comparison.RESULTS The median total volume of contrast medium was 133.0 mL in the control group vs 140.0 mL in the LMWD group.Although baseline renal function was not statistically different between these two groups,the LMWD group demonstrated a strong trend toward the progression of renal insufficiency as indicated by the greater change in serum creatinine level during the 1-year follow-up compared with the control group.Patients in the LMWD group experienced worsening renal function more frequently than patients in the control group.Propensity score matching adjusted for total contrast media volume consistently indicated a trend toward worsening renal function in the LMWD group at the 1-year follow-up.Delta serum creatinine at 1-year follow-up was significantly greater in the LMWD group than that in the control group[0.06(-0.06,0.29)vs-0.04(-0.23,0.08)mg/dL,P=0.001],despite using similar contrast volume.CONCLUSION OCT using LMWD may not be protective against worsening renal function in patients with advanced renal insufficiency.

Forty-six Cases of Vertebrobasilar Insufficiency Treated by Acupuncture plus Intravenous Infusion of Ligustrazine

Objective: To observe the therapeutic effect of acupuncture plus Ligustrazine on vertebrobasilar insufficiency (VBI) by transcranial Doppler (TCD) sonography. Methods: 86 VBI patients including 56 cases of low flow rate velocity type (LFVT) and 30 cases of high flow velocity type (HFVT) were randomly divided into Ligustrazine group (26 LFRT and 14 HFVT) and acupuncture plus Ligustrazine group (30 LFVT and 16 HFVT). The blood flow velocity (BFV) of vertebral artery (VA) and basilar artery (BA) in systole before and after treatment was measured with TCD and therapeutic effects were evaluated after 10 days’ treatment in the two groups. Results: In the acupuncture plus Ligustrazine group, the total effective rate was 93.3% and 88.5% in cases of LFVT and HFVT respectively, and BFV of VA and BA increased in LFVT patients while that in HFVT patients decreased significantly (P<0.05 or P<0.01). Conclusion: Owing to its dual regulation on blood flow of VA and BA, the therapeutic effect of acupuncture plus Ligustrazine was better than that of simple Ligustrazine.

Effect of bivalirudin on coagulation function and prognosis in patients with coronary artery disease and renal insufficiency undergoing PCI

Background Renal insufficiency is associated with an excess risk of vascular complications and bleeding events in patients who undergo PCI. Heparin is still used commonly for PCI, but the bleeding complications is high. However, Bivalirudin is similar to heparin in ischemic complications and superior to the bleeding complica- tions. Methods A total of 181 patients with coronary artery disease and renal insufficiency were randomly as- signed two treatment groups： Bivalirudin （n = 90）, unfractionated heparin （n = 91）. Activated clotting time （ACT） was determined in patients at 5 min after undergoing PCI at the end of operation immediately （stopping drug im- mediately） , and 30 min,1 h, 2 h after stopping drug. Activated partial thromboplastin time （APTT）, thrombin time （TT）, proth rombin time （PT）, fibrinogen （FIB） index were measured before treatment, 6 h, 24 h and 72 h af- ter the treatment through an automated coagulation analyzer. Platelet count was monitored before treatment and 24 h after treatment. The end points were the proportion of net adverse clinical events （NACE） and stent throm- bosis at 30 days. Results The use of bivalirudin was associated with a statistically significant higher at 5 min af- ter treatment, end of operation immediately （P 〈 0.05）, with statistically significant lower at lh after stopping drug , 2h after stopping drug （P 〈 0.05）. There were no differences between patients at blood coagulation and platelet after operation （P 〉 0.05）, no differences in the 30-day rates of stent thrombosis （0% vs. 0%, P = 1）. Elev- en patients（12.22%） treated with bivalirudin vs. 24 （26.38%） treated with heparin experienced an adverse clinical events at 30 days （relative risk[RR], 0.46; 95%CI, 0.36-0.56; P 〈 0.025）. There were no differences in the major adverse cardiac or cerebral event at the 30-day end point（1.11% vs. 2.20%, P 〉 0.05）. The bleeding at 30 days was abated by using bivalirudin compared with unfracfionated heparin （11.11% vs. 24.18%, P 〈 0.05）. Conclu- sions Compared with the unfractionated heparin, bivalirudin is more quickly in taking effect and recovering and more efficient for PCI in patients with coronary artery disease and renal insufficiency.

Vertebrobasilar artery dissection manifesting as Millard-Gubler syndrome in a young ischemic stroke patient: A case report

BACKGROUND Millard-Gubler syndrome(MGS) is caused by a lesion in the brainstem at the level of the facial nerve nucleus, and it is also a rare ventral pontine syndrome.Vertebrobasilar artery dissection(VAD) is an uncommon cause of ischemic stroke. To the best of our knowledge, this is the first case report on the coexistence of MGS and VAD in a young acute ischemic stroke patient.CASE SUMMARY We herein describe an unusual case of young acute ischemic stroke patient,presenting with acute right peripheral facial palsy, right abducens palsy, and contralateral hemihypesthesia, manifesting as MGS. After receiving dual antiplatelet therapy with aspirin and clopidogrel, as well as rosuvastatin, the patient recovered significantly. The high-resolution magnetic resonance imaging(MRI) indicated a diagnosis of VAD.CONCLUSION Our finding further demonstrated that high-resolution MRI is a useful technique to early detect underlying dissection in posterior circulation ischemic stroke.

Angioplasty and stenting for severe vertebral artery orifice stenosis: effects on cerebellar function remodeling verified by blood oxygen level-dependent functional magnetic resonance imaging

Vertebral artery orifice stenting may improve blood supply of the posterior circulation of the brain to regions such as the cerebellum and brainstem. However, previous studies have mainly focused on recovery of cerebral blood flow and perfusion in the posterior circulation after interventional therapy. This study examined the effects of functional recovery of local brain tissue on cerebellar function remodeling using blood oxygen level-dependent functional magnetic reso- nance imaging before and after interventional therapy. A total of 40 Chinese patients with severe unilateral vertebral artery orifice stenosis were enrolled in this study. Patients were equally and randomly assigned to intervention and control groups. The control group received drug treat- ment only. The intervention group received vertebral artery orifice angioplasty and stenting ＋ identical drug treatment to the control group. At 13 days after treatment, the Dizziness Handicap Inventory score was compared between the intervention and control groups. Cerebellar function remodeling was observed between the two groups using blood oxygen level-dependent functional magnetic resonance imaging. The improvement in dizziness handicap and cerebellar function was more obvious in the intervention group than in the control group. Interventional therapy for severe vertebral artery orifice stenosis may effectively promote cerebellar function remodeling and exert neuroprotective effects.

Atypical case of bow hunter’s syndrome linked to aberrantly coursing vertebral artery: A case report

BACKGROUND In bow hunter’s syndrome(BHS),also known as rotational vertebral artery(VA)syndrome,there is dynamic/rotational compression of the VA producing verte-brobasilar insufficiency.Most occurrences involve atlantoaxial rather than mid-cervical VA compromise,the latter being rarely reported.Herein,we detail successful VA decompression at mid-cervical spine,given a departure from its usual course.CASE SUMMARY The patient,a 45-year-old man,presented to our hospital with occipital headache and vertigo.Computed tomography angiography showed anomalous C4 entry of right VA,with compression upon head rotation to that side.Thyroid cartilage and anterior tubercle of C5 transverse process were visibly at fault.We opted for sur-gery,using an anterior cervical approach to remove the anterior tubercle.Patient recovery was uneventful and brought resolution of all preoperative symptoms.CONCLUSION BHS is an important consideration where aberrant coursing of VA and neurologic symptoms coexist.

Incidental Finding of a Fenestrated Vertebrobasilar Junction Aneurysm

Basilar artery fenestration is a rare anatomical variation resulting from the failed fusion of the two vertebral arteries during embryonic life. In order of frequency, it is the second most common location of vascular fenestrations after the anterior communicating artery. Vertebrobasilar junction aneurysms are uncommon but often associated with basilar artery fenestration. We report the case of a fenestrated vertebrobasilar junction saccular aneurysm in a 57-year-old woman. The diagnosis was incidentally made on CT angiography which found the anatomical variant and the aneurysm. The radiological features illustrating this association are detailed here and a brief discussion of its pathogenesis and management was made. Vertebrobasilar junction aneurysms are rare and their presence should suggest an associated basilar fenestration.
