A novel imaging biomarker for prediction of cerebrovascular ischemic events: Pericarotid fat density.

Background: To investigate the relationship between pericarotid fat density measured in carotid CTA and vulnerable carotid plaque.

Methods: This retrospective study included 374 participants who underwent carotid CTA between June 1, 2021, and December 1, 2021 (234 males, median age 68 years [interquartile range: 61-75]). Two groups, symptomatic and asymptomatic, were defined based on either diffusion-weighted MRI or a clinical history of acute ischemia or TIA within 6 months before or after CTA.

Tigecycline-Associated Hepatic Steatosis After Liver Transplant: A Case Report.

Tigecycline is a parenteral glycycline antibiotic that is used to treat severe infections caused by susceptible organisms, butitis also associated with hepatotoxicity. We present 2 similar patients with hepatic steatosis possibly associated with early tigecycline after transplant. In the first case, a 61-year-old woman underwent liver transplant for acute severe hepatitis; 6 days posttransplant, because of nonroutine resistant fever, the patient received tigecycline combined with daptomycin.

Effect of Pretransplant Sarcopenia on Mortality in Liver Transplant Recipients.

Objectives: Sarcopenia is an important metabolic disorder associated with end-stage liver disease and is an independent predictor of mortality in liver transplant candidates. We evaluated effects of pretransplant muscle mass, muscle quality, and visceral adipose tissue on mortality after liver transplant.

Materials And Methods: For 2015-2020, we included 65 liver transplant recipients whose records contained pretransplant liver computed tomography images.

Comparison of clinical characteristics of wild-type SARS-CoV-2 and Omicron.

Objective: This study aimed to investigate the effect of mutations by comparing wild-type SARS-CoV-2 and Omicron regarding clinical features in patients with COVID-19. It also aimed to assess whether SARS-CoV-2 cycle threshold value could predict COVID-19 severity.

Methods: A total of 960 wild-type and 411 Omicron variant patients with positive results in SARS-CoV-2 real-time reverse transcriptase polymerase chain reaction test from oropharyngeal and/or nasopharyngeal samples during their hospital admissions were included in this retrospective study.

Pacemaker-associated superior vena cava syndrome: Role of contrast echocardiography.

Pacemaker-associated superior vena cava (SVC) syndrome is increasingly recognized as a nonmalignant type of SVC syndrome. Computed tomographic (CT) angiography is the first choice of imaging for diagnosis but in some cases there is discrepancy between the clinical findings and CT images. In this report we present the role of contrast study with transesophageal echocardiography in a patient with suspicion of SVC syndrome but inconclusive CT findings.

Color Doppler ultrasound for surveillance following EVAR as the primary tool.

Objective: As aneurysm-related events and rupture is not eliminated, postoperative lifelong surveillance is mandatory after endovascular aneurysm repair (EVAR). For surveillance colored Doppler ultrasound (CDUS) is a standard method of noninvasive evaluation having the advantages of availability, cost-effectiveness, and lack of nephrotoxicity and radiation. We evaluated CDUS for primary surveillance tool after elective EVAR by comparing with computerized tomography.

Change from Cardioinhibitory Syncope to Iatrogenic Positional Syncope: Superior Vena Cava Syndrome Treated by Superior Vena Cava Stenting and Leadless Pacemaker Implantation.

Symptomatic obstruction of the superior vena cava can be caused by either intrathoracic malignancy or nonmalignant etiology, resulting in superior vena cava syndrome (SVCS). The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign SVCS. We present a post-pacemaker-implantation case of SVCS manifesting as positional syncope.

Multidetector Computed Tomography Findings of Splenic Artery Aneurysms Associated With Liver Involvement in Wilson's Disease.

Purpose: The purposed of this study was to examine the incidence and multidetector computed tomography (MDCT) findings of splenic artery aneurysms (SAAs) in patients with liver involvement related to Wilson's disease.

Methods: Eighteen patients with clinically and/or pathologically proven Wilson's disease underwent triphasic MDCT. Arterial, portal, and equilibrium phase images were obtained.

A Single-Center Retrospective Comparison of Doxorubicin-Loaded HepaSphere Transarterial Chemoembolization with Conventional Transarterial Chemoembolization for Patients with Unresectable Hepatocellular Carcinoma.

Purpose: To compare doxorubicin-loaded HepaSphere transarterial chemoembolization versus conventional transarterial chemoembolization in terms of survival, time to recurrence, acute reversible hepatotoxicity, postembolization syndrome, and chemoembolization-related mortality and morbidity.

Materials And Methods: One hundred twenty-six patients (103 men, 23 women; mean age, 64.3 y) with unresectable hepatocellular carcinoma (HCC) who underwent conventional chemoembolization between January 2007 and March 2011 or drug-eluting embolic (DEE) chemoembolization (after the protocol change) between March 2011 and October 2014 were included in a retrospective analysis.

Splenic infarction after N-butyl-2-cyanoacrylate injection for gastric varices: why does it happen?

Recent guidelines and consensus reports recommend endoscopic injection therapy with N-butyl-2-cyanoacrylate as the first-line treatment for bleeding-isolated gastric varices and gastroesophageal varices types 1 and 2. Embolization is a rare but serious complication of cyanoacrylate injection, which may be fatal in some cases. Herein, we present a patient who developed splenic infarction after N-butyl-cyanoacrylate injection for gastroesophageal varices type 2 and discuss the potential reasons and tips to prevent the occurence of embolization.

Syncope as the primary manifestation of hydatid cyst. Report of two cases with different etiologies.

Hydatid disease is a parasitic infestation that is caused by the larvae of the tapeworm Echinococcus granulosus. Clinical manifestations are extremely variable and related to the location and the size of the cysts. Syncope as the first clinical presentation of hydatid cyst is a very rare condition.

Long-term results of percutaneous biliary balloon dilation treatment for benign hepaticojejunostomy strictures: are repeated balloon dilations necessary?

Purpose: To determine the safety, efficacy, and long-term results of percutaneous biliary balloon dilation (PBBD) of benign hepaticojejunostomy strictures and evaluate the necessity of repeated PBBD in this setting.

Materials And Methods: PBBD was performed after traversing hepaticojejunostomy strictures in 89 patients (40 male, 49 female; age range, 19-84 y; mean age ± SD, 54.5 y ± 14.

Severe main coronary artery disease in a young woman with ankylosing spondylitis.

Patients with ankylosing spondylitis (AS) have an approximately two-fold increased death rate compared to the general population, which is predominately caused by increased cardiovascular risk. The prevalence rate for myocardial infarction is approximately 2-3 fold increased as compared with the general population. The inflammatory process appears to have an important role in causing this excess cardiovascular risk.

Self-expanding covered metallic stent treatment of esophagojejunostomy fistulas.

Purpose: The purpose of this study is to analyze the outcomes of the self-expanding covered metallic stent (SECMS) therapy in the management of the postoperative anastomotic leaks that seen after total gastrectomy-esophagojejunostomy (EJ) operations.

Materials And Methods: Contrast radiography and endoscopy revealed EJ fistulas in 14 patients. SECMSs were implanted both fluoroscopically and endoscopically to seal fistulas.

Percutaneous biliary intervention for primary sclerosing cholangitis in a patient with situs inversus totalis.

Situs inversus totalis is a rare condition that may not cause symptoms and often occurs concomitantly with other congenital anomalies. Special attention must be given to these patients when invasive interventions are required. There are only a few reports concerning percutaneous transhepatic biliary interventions in situs inversus totalis, but technical details were not fully explained.
