Mediastinal Drain Placement: A CT-Guided Para-Aortic Approach

A 92-year-old woman with a foreign body perforation of the esophagus underwent esophageal repair and esophageal stent placement. A computed tomography (CT) scan of the chest performed for worsening leukocytosis demonstrated an enlarging air-containing mediastinal collection despite a surgically placed mediastinal drain; interventional radiology was consulted. The 3-day-old anteriorly placed drain had a long infracardiac course, and drain exchange was believed to be too high risk for loss of access.

Purpose: Preoperative progressive pneumoperitoneum (PPP) has not been reported in the management of parastomal hernias; therefore, the present study evaluated its effectiveness in the surgical management of large parastomal hernias. Patients and Methods: This prospective, observational study included 23 consecutive patients with large parastomal hernias who underwent PPP between January 2016 and September 2018. The volume of parastomal hernia (VPH), volume of the abdominal cavity (VAC), and the VPH/VAC ratio were measured before and after PPP using abdominal computed tomography scan data. All the hernias were repaired...

This study examines the differences in perioperative mortality and postoperative survival between men and women following elective repair of AAAs in the 10 years after implementation of the (VSQIP). METHODS: Consecutive patients who underwent elective repair of AAA between 1stJanuary 2008 and 31st March 2018 were included. All patients were assessed using the nationally agreed VSQIP pathway which involved cardiopulmonary exercise testing as well as contrast enhanced CT scan of aorta and multidisciplinary assessment to plan each treatment. CT scans were examined to assess the morphology of AAA. Patients were stratified...

AbstractMitral annular disjunction (MAD) is routinely diagnosed by cardiac imaging, mostly by echocardiography, and shown to be a risk factor for ventricular arrhythmias. While MAD is associated with mitral valve (MV) prolapse (MVP), it is unknown which patients with MAD are at higher risk and which additional imaging features may help identify them. The value of cardiac computed tomography (CCT) for the diagnosis of MAD is unknown. Accordingly, we aimed to: (1) develop a standardized CCT approach to identify MAD in patients with MVP and severe mitral regurgitation (MR); (2) determine its prevalence and identify features t...

AbstractPurpose of ReviewThis review discusses imaging modalities for fracture repair assessment, with an emphasis on pragmatic clinical and translational use, best practices for implementation, and challenges and opportunities for continuing research.Recent FindingsSemiquantitative radiographic union scoring remains the clinical gold standard, but has questionable reliability as a surrogate indicator of structural bone healing, particularly in early-stage, complex, or compromised healing scenarios. Alternatively, computed tomography (CT) scanning enables quantitative assessment of callus morphometry and mechanics through ...

CONCLUSION: Approximately a quarter of the patients developed complications, the majority of which were asymptomatic, underlining the importance of adequate surveillance. There was good agreement between CTA and DUS in detecting complications. Clinically significant complications related to inadequate seal were missed by DUS, suggesting that CTA still plays an important role in EVAR surveillance.

Goal: Ascending thoracic aortic aneurysm (aTAA) is a major cause of human deaths. Despite important recent progress to better understand its pathogenesis and development, the role played by deranged hemodynamics on aTAA risk of rupture is still partially unknown. Our aim was to develop and apply a novel methodology to assess the correlation between aTAA rupture risk and hemodynamic biomarkers combining for the first time in vivo, in vitro and in silico analyses. Methods: Computational fluid dynamic (CFD) analyses were performed and validated on 10 patients using patient-specific data derived from CT scan and 4D MRI. Systol...

We present a case of a 15-year-old boy who was stabbed with a bamboo stick in his left eye. The chopsticks passed through the orbit roof and penetrated the skull base. In subsequent days, the patient sustained CSF leak and intracranial infection after an unsatisfied primary treatment in the local hospital and had to request a secondary operation in our department. Computed tomography including plain scan, three dimension reconstruction and computed tomographic angiography are used to determine the course and extent of head injury. A frontal craniotomy was performed. Three pieces of stick were found residual and removed wit...

In this study, we applied 18F-alfatide II positron emission tomography/computed tomography (PET/CT) to monitor angiogenesis in an SCI model after estrogen (E2) treatment, as well as to evaluate the prognosis in a noninvasive manner. The SCI model was established with male rats and the rats were randomly divided into E2-treated group (SCI + E2) and E2-untreated group (SCI). Sham group was also used as control (Sham). The angiogenesis after SCI was monitored by 18F-alfatide II PET/CT and verified by immunofluorescence of CD31 and CD61. We also evaluated the level of E2 and growth-associated protein 43 (GAP43) by enzyme-linke...

This study aimed to evaluate 2 advanced methods for presurgical calculation of bilateral alveolar cleft defect volume using 3-dimensional (3D) printing and computer-aided engineering (CAE) software. Twelve patients with bilateral alveolar cleft (4 females, 8 males, age range 8–11 years) were enrolled in the study. All patients underwent preoperative helical computed tomography scans, and the digital imaging and communications in medicine (DICOM) data of the computed tomography images were analyzed using 3D printing and CAE software. The 3D-printed model used a simulated graft, and graft volume was measured by water d...
