Clinical predictors for the manifestation of late gadolinium enhancement after acute myocardial infarction
We examined 136 patients after first ST-elevated myocardial infarction by CMR after a median of 4 days (range: 2–7). Patients with manifestation of LGE were matched to patients without LGE by means of age and gender. Clinical follow-up with a combined primary endpoint including myocardial reinfarction, congestive heart failure, stroke, death and development of left ventricular thrombus was reported after 24 months.
Patients with manifestation of LGE had a significant longer time of symptom-to-intervention, a higher prevalence of anterior AMI, and more proximal culprit lesions. Furthermore, left ventricular ejection frac...

Cerebrovascular risk factors for patients with cerebral watershed infarction: A case–control study based on computed tomography angiography in a population from Southwest China
Abstract: To determine cerebrovascular risk factors for patients with cerebral watershed infarction (CWI) from Southwest China.
Patients suffering from acute ischemic stroke were categorized into internal CWI (I-CWI), external CWI (E-CWI), or non-CWI (patients without CWI) groups. Clinical data were collected and degrees of steno-occlusion of all cerebral arteries were scored. Arteries associated with the circle of Willis were also assessed. Data were compared using Pearson chi-squared tests for categorical data and 1-way analysis of variance with Bonferroni post hoc tests for continuous data, as appropriate. Multivariate...

Deep cerebral microbleeds are associated with the severity of lacunar infarcts and hypertension: A retrospective analysis
This study retrospectively analyzed 166 patients with ischemic stroke or transient ischemic attacks admitted in the Geriatric Neurology Department of Chinese PLA General Hospital between February 2010 and December 2012. We collected clinical characteristics and risk factors of CMBs. The location of CMBs on T2*-weighted angiography was assessed by the Microbleed Anatomical Rating Scale. The number of lacunar infarcts and the severity of white matter hyperintensities were also recorded. The association between the location of CMBs and lacunar infarcts parameters was examined.
CMBs were present in 77 (46.4%) patients. The pr...

A case report on middle cerebral artery aneurysm treated by rapid ventricular pacing: A CARE compliant case report
Rationale:
Cerebral aneurysm is a common cause of intracranial hemorrhage, stroke, and death. It is treated with vascular surgeries, such as coil embolism and artery clipping. However, surgery itself is a risk factor that may cause rupture of aneurysm, and leads to irreversible brain damage, and even death. Rapid ventricular pacing (RVP) is a procedure that temporarily lowers blood pressure by increasing heart rate and reducing ventricular filling time. RVP has been widely used to reduce blood vessel tension in many cardiovascular surgeries.
Patient concerns:
A 46-year-old man came to our hospital with intermittent ri...

Atypical “nine” syndrome in bilateral pontine infarction: A case report
This study aimed to report a Chinese patient with acute bilateral pontine infarction manifesting as eight-and-a-half syndrome plus hemiplegia (atypical nine syndrome), and also the clinical and neuroimaging findings were explained and discussed with review of the literature.
Patient concerns:
A 79-year-old woman experienced sudden vertigo, nausea, vomiting, and weakness at her left arm and leg. The neurological examination disclosed her right horizontal gaze palsy, internuclear ophtalmoplegia (INO), and right-sided peripheral facial paralysis combined with slight left-sided hemiplegia, which were consistent with atypica...

Interventional recanalization as a treatment of carotid stump syndrome caused by right internal carotid artery occlusion: A case report
Rationale:
Carotid stump syndrome is a cerebral infarction caused by an embolus formed subsequent to the vortex of blood flow from the occluded stump, which then moves through the collateral vessels into the brain. The covered stent and stent-assisted coil embolization stump are the effective interventions for the carotid artery stump.
Patient concerns:
A 71-year-old man twice experienced left limb weakness; diffusion weighted imaging confirmed the diagnosis of cerebral infarction. Cervical computed tomography angiography, intracranial magnetic resonance angiography, and digital subtraction angiography were conducted ...

How to continue lipid-lowering therapy in patients with coronary heart disease and severe liver dysfunction?: A case report of plaque regression by a combination of Chinese and Western Medicine
Rationale:
Atherosclerotic cardiovascular disease (ASCVD), including coronary heart disease (CHD), atherosclerotic stroke and peripheral vascular disease, has become the most deadly chronic noncommunicable disease throughout the world in recent decades, while plaque regression could reduce the occurrence of ASCVD. Traditional Chinese Medicine (TCM) has been widely used for prevention and treatment of these diseases. In the perspective of TCM, phlegm and blood stasis are considered to be leading pathogenesis for CHD. Hence, activating blood circulation and dissipating phlegm, which is of great benefit to regress plaque, h...

Cerebral sinovenous thrombosis in a child with ulcerative colitis: A case report
Rationale:
Cerebral sinovenous thrombosis (CVT) associated with inflammatory bowel disease (IBD) is infrequent, but clinically nonnegligible due to its high disability and fatality rates.
Patient concerns:
A 12-year-old child with newly developed ulcerative colitis (UC) suffered from a sudden left-sided hemiparesis and numbness.
Diagnoses:
Cerebral sinovenous thrombosis due to ulcerative colitis was diagnosed in this girl.
Interventions:
The patient was treated with blood transfusion and anticoagulation therapy. Digital subtraction angiography (DSA) and urokinase thrombolysis were implemented followed.
Outcomes...

Pulmonary arteriovenous malformation exhibiting recanalization >10 years after coil embolization: Two case reports
We described the first 2 cases diagnosed with PAVM recanalization>10 years after the first catheter embolization. These cases suggest that patients with PAVMs should undergo life-long follow-up after catheter embolization.

r-tPA with loading dose of clopidogrel and aspirin therapies for capsular warning syndrome attributed to middle cerebral artery atherosclerotic stenosis: A CARE-compliant case report
Rationale:
The capsular warning syndrome (CWS) is a rare and special type of transient ischemic attacks (TIAs) syndrome. The pathophysiology of CWS is very complicate, and intracranial atherosclerotic stenosis (ICAS) is rare cause. Moreover, the effective and standard therapy has not yet been established.
Patient concerns:
A 47-year-old man experienced repeated and exacerbated TIAs of right hemiparesis and dysarthria. Fourteen hours after the first episode of TIAs, he developed more severe right hemiparesis and dysarthria, the National Institute of Health Stroke Scale (NIHSS) score was 12 points, and did not recover i...

Plaque features and vascular geometry in basilar artery atherosclerosis
Hemodynamic changes occurring at the segments of arterial bifurcations, up and down stream of stenotic vessels appear to play a critical role in the development of atherosclerosis. Therefore, we hypothesized that basilar artery (BA) geometry may be related to the distribution of atherosclerotic plaque.
In this retrospective cross-sectional study, all patients hospitalized with ischemic stroke and intracranial atherosclerotic disease were sifted from March 2017 to October 2017. Sixty-seven patients with intracranial atherosclerotic disease (39 with and 28 without BA atherosclerosis) were analyzed. Magnetic resonance imagin...

Acute basilar artery occlusion with recurrent shivering: A case report
Rationale:
Shivering is an important physiological response of the body that causes muscle tremors to maintain temperature homeostasis. Traumatic brain injuries that affect the hypothalamus cause hypothermia, and physical removal of suprasellar tumors causes thermoregulation imbalance. However, no study has reported shivering due to ischemic stroke.
Patient concerns:
A 58-year-old male patient was admitted to our emergency department to evaluate severe stenosis of the basilar artery. While waiting for further examination, he exhibited coarse shivering and severe dysarthria.
Diagnosis:
Brain computed tomography angi...
