ABSTRACT

Objective:To investigate the association of white matter hyperintensities (WMHs) with long-term stroke recurrence in patients with recent subcortical small infarcts (RSSIs).Methods:Consecutive patients admitted to the Department of Neurology, Hefei Hospital Affiliated to Anhui Medical University between January 2019 and August 2022 and met the clinical and imaging manifestations of RSSIs were collected. The demographic characteristics, baseline clinical data, and MRI features were collected. Using stroke recurrence as the endpoint event, the recurrence time was recorded, and Cox regression model was used to analyze relevant factors affecting stroke recurrence in patients with RSSIs.Results:A total of 202 patients were enrolled, including 138 males (68.3%), aged 67.9±10.5 years. Seventy-seven patients (38.1%) were mild WMHs, 64 (31.7%) were moderate WMHs, and 61 (30.2%) were severe WMHs. There were statistically significant differences in age, history of stroke, hypertension, hyperlipidemia, total cholesterol, infarct thickness, and infarct distribution among different WMHs severity groups (all P<0.05). The median follow-up time was 40.5 months (interquartile range, 27.7-49.0 months), and a total of 55 patients (27.2%) had stroke recurrence (ischemic stroke 54, occipital hemorrhage 1). Recurrence rates of stroke in the mild, moderate, and severe WMHs groups were 18.2%, 31.3%, and 34.4%, respectively. Cox regression analysis showed that WMHs were an independent risk factor for stroke recurrence (compared to the mild group, the risk ratio of the severe group was 2.225, 95% confidence interval was 1.116-4.436; P=0.023). Conclusion:The risk of long-term stroke recurrence in patients with RSSI is associated with the severity of WMHs.

ABSTRACT

Severe acute cholangitis, also called acute obstructive suppurative cholangitis (AOSC), has acute onset and rapid progression and is the primary cause of death in patients with benign biliary tract diseases, especially in elderly patients, and it is often complicated by multiple system organ failure. This disease has diversified symptoms and signs, which leads to the inconsistency in diagnostic grading and prognosis criteria. With the development of minimally invasive surgery and endoscopic techniques, the diagnosis and treatment of severe acute cholangitis has been constantly improved. Therefore, judgment and selection of the optimal surgical timing, individualized biliary drainage, and comprehensive, standardized, and timely anti-infective therapy based on prognostic factors have great importance in the treatment of severe acute cholangitis.

ABSTRACT

Objective To investigate the correlation between ipsilateral posterior cerebral artery laterality (PCAL) and the outcomes in patients with ischemic stroke in the middle cerebral artery (MCA) territory. Methods From June 2015 to December 2016, patients with acute ischemic stroke in the MCA territory admitted to the Second People's Hospital of Hefei were enrolled. Magnetic resonance angiography (MRA) was used to assess PCAL. The outcome was evaluated by the modified Rankin scale at 3 months after onset. 0-2 was defined as good outcome and > 2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results A total of 111 patients with ischemic stroke in MCA territory were enrolled, including 47 (42. 3%) PCAL and 30 (27. 0%) poor outcomes. The baseline NIHSS score in the PCAL group was significantly lower than that in the non-PCAL group (5. 13 ± 3. 29 years vs. 7. 03 ± 5. 676 years, t = 2. 058; P = 0. 042). There were significantly differences in the proportion of diabetes mellitus (29. 6% vs. 10. 0%; χ2 = 4. 583, P = 0. 032), PCAL (51. 9% vs. 16. 7%;χ2 = 11. 101, P = 0. 001) and smoking (25. 9% vs. 13. 3%; χ2 = 4. 943, P = 0. 026), as well as age (63. 9 ± 11. 8 years vs. 71. 0 ± 6. 7 years; t = 2. 688, P = 0. 007), baseline diastolic blood pressure (89 ± 13 mmHg vs. 82 ± 10 mmHg; t = -2. 249, P = 0. 025; 1 mmHg = 0. 133 kPa) and baseline NIHSS score (5. 02 ± 3. 67 vs. 9. 47 ± 6. 20; t = 3. 883, P < 0. 001) between the good outcome group and the poor outcome group. Multivariate logistic regression analysis showed that PCAL was associated independently with good outcome (odds ratio [OR] 0. 272, 95% confidence interval [CI] 0. 083-0. 888; P = 0. 031), while advanced age (OR 1. 088, 95% CI 1. 022-1. 157; P = 0. 008) and high baseline NIHSS score (OR 1. 224, 95% CI 1. 077-1. 391; P = 0. 002) were associated independently with poor outcome. Conclusion PCAL is associated independently with good outcome in patients with ischemic stroke in MCA territory.

ABSTRACT

Objective To summarize the experience of clinical diagnosis and treatment of portal vein stenosis after liver transplantation. Methods Clinical data of 18 patients presenting with portal vein stenosis after undergoing liver transplantation were retrospectively analyzed. The incidence, treatment and prognosis of portal vein stenosis were summarized. Results Seventeen patients had a medical history of liver cirrhosis before liver transplantation, 7 cases with a medical history of portal vein thrombosis and 8 cases with a medical history of devascularization or shunt with splenectomy. Three cases received the pediatric liver grafts. Eighteen patients suffered from portal vein stenosis from postoperative 23 d to 24 months with a median time of 2.2 months, which was detected by color Doppler ultrasound (CDU) and diagnosed by CT angiography (CTA) of the portal vein or interventional therapy. After the diagnosis was confirmed,all cases received anticoagulant treatment by warfarin. Five patients with portal hypertension underwent balloon dilatation,and one of them received endovascular stent implantation simultaneously. The remaining 13 patients received conservative therapy. After corresponding treatment, 9 cases were mitigated, 7 patients remained unchanged and 2 cases were aggravated. Conclusions For the recipients with a medical history of liver cirrhosis before liver transplantation, portal vein stenosis should be monitored by conventional CDU and diagnosed by CTA or interventional therapy after transplantation. Patients without clinical symptoms can receive conservative treatment. Those complicated with portal hypertension can undergo interventional therapy. Favorable clinical prognosis is obtained in most cases.
