Detection of Costal Cartilage Fractures on CT Images With Computer-aided Detection System for Rib Fractures.

Background/aim: Costal cartilage fractures are associated with poor prognosis in patients with blunt chest trauma. A Computer-Aided Detection (CAD) system for detecting rib fractures has been used in practice, but it is unclear whether this system recognizes costal cartilage fractures. This study investigated whether the CAD system for rib fracture can detect costal cartilage fractures.

Chest Compression-Associated Internal Thoracic Artery Injury During Cardiopulmonary Resuscitation: Incidence, Injury Patterns and Efficacy of Transcatheter Arterial Embolization.

Purpose: To investigate the incidence and patterns of chest compression-associated internal thoracic artery injury (CAI) during cardiopulmonary resuscitation and identify the embolization techniques used to treat hemorrhage.

Materials And Methods: A retrospective study was conducted in the patients who underwent transcatheter arterial embolization (TAE) for life-threatening hemorrhage caused by CAI at two tertiary care centers between May 2013 and December 2019. Data on background characteristics, imaging findings, embolization and outcomes were collected from the medical records.

Natural History of Unruptured Visceral Artery Aneurysms Due to Segmental Arterial Mediolysis and Efficacy of Transcatheter Arterial Embolization: A Retrospective Multiinstitutional Study in Japan.

The purpose of this study was to clarify the natural history of unruptured visceral artery aneurysms due to segmental arterial mediolysis and the efficacy of transcatheter arterial embolization. Patients with a pathologic or clinical diagnosis of visceral artery aneurysms due to segmental arterial mediolysis between 2005 and 2015 were enrolled. For patients with clinical diagnoses, images were collected and assessed by central radiologic review.

Risk factors of recurrence after postoperative electron beam radiation therapy for keloid: Comparison of long-term local control rate.

Aim: To investigate the new risk factors for keloid recurrence after postoperative electron beam radiotherapy (RT) and evaluate the effectiveness of tranilast in combination with electron beam RT by comparing the local control rate.

Background: Identifying patients at high risk of recurrence after postoperative RT for keloids remains a challenge. Besides, no study examined the effectiveness of tranilast in combination with RT after surgery for the prevention of keloids recurrence.

Stanford type IV venous collateral blood flow following complete chronic occlusion of the superior vena cava in a patient with lung cancer.

In superior vena cava occlusion, multiple collateral pathways develop to maintain venous drainage. Major patterns and pathways of venous collateral blood flow are well described, but rarely in complete chronic superior vena cava occlusion secondary to malignancy. A 59-year-old man with facial and upper extremity edema had a severely compressed superior vena cava at the initial diagnosis of stage IV mediastinal lung adenocarcinoma.
