Percutaneous Y-shape reconstructive biliary stenting in Klatskin cholangiocarcinoma through a single left-sided entry.

Percutaneous Y-shape reconstructive biliary stenting in the Klatskin tumor is typically performed through bilateral biliary access. Single access from a right-side biliary entry is the more commonly used side for biliary access in general. We present a successful Y-shaped biliary stent reconstruction through a single left-side biliary approach.

The Role of Cerebral CT Angiogram in Subacute Ischemic Cerebrovascular Events.

Background: Stroke is a spectrum of medical emergencies resulting from a direct insult to the cerebral blood flow. Cerebral computed tomography angiogram (CTA) plays an important role in the diagnostic algorithm of acute stroke. However, the role of CTA in the subacute phase is not well-established.

Coronavirus Disease (COVID-19) Compared with Middle East Respiratory Syndrome (MERS): A Radiological Perspective.

Background: This study aims to describe the radiological findings in chest radiographs (CXRs) of patients with coronavirus disease (COVID-19) and the Middle East respiratory syndrome (MERS) and to compare the radiological patterns of the two diseases.

Methods: A retrospective cohort study was conducted in a tertiary care hospital in the Southern region of Saudi Arabia. The CXRs were evaluated for the presence and distribution of ground-glass opacities (GGO), consolidation, pleural effusions, pneumothorax, cavitation, and nodules.

Coronary artery calcium score above 250 confirms the presence of significant stenosis in coronary CT angiography of symptomatic patients.

Objectives: Evaluation of coronary artery calcium score (CACS) at multiple low and high cutoff values for the detection of significant coronary stenosis at two different cutoffs (50 and 70%) in a large number of symptomatic patients was not investigated previously in one study. This study aims to investigate if there are a correlation and statistical significance between different CACS cutoffs and the severity of coronary artery stenosis by coronary CT angiography (CCTA) in symptomatic patients.

Methods: This is a retrospective study that included all symptomatic patients who had CCTA in a tertiary care hospital over a period of 7 years.

Diagnostic yield of CT pulmonary angiography for pulmonary embolism in clinically suspected patients.

Pulmonary embolism (PE) is a common medical problem. Its diagnostic criteria must be reviewed to determine the need for confirmatory testing. Computed tomography pulmonary angiography (CTPA) is the current standard of care, which provides accurate diagnosis with rapid turnaround.
