Objective: This study investigated the composition of pathogenic microorganisms, clinical features, and therapeutic strategies of infective artery rupture of renal allografts in recipients receiving deceased donor (DD) kidneys.
Methods: We retrospectively studied the clinical data of the DD kidney transplant recipients with donor-associated infection at Tongji Hospital, Wuhan, China from January 1, 2015 to December 31, 2018, related recipients and corresponding donors. We collected the entire results of pathogenic microorganisms cultured from these related ruptured kidneys and then analyzed their distribution and differences.
Results: A total of 1440 kidney transplants from DD were performed in our center. The total incidence of infective artery rupture in kidney transplants was about 0.76% (11/1440), and the annual incidence ranged from 0.25% to 1.03%. The microbial culture results revealed that 11 recipients suffered from infective artery rupture and 3 recipients who accepted the kidney from same donor had the donor-associated pathogens, including 9 fungal strains (28.1%) and 23 bacterial strains (71.9%). There were 4 recipients infected with multi-drug-resistant Staphylococcus and Klebsiella pneumoniae from the above 11 recipients, of which, 10 recipients underwent graft loss, and one died of septic shock. The microbial cultures of the remaining 3 recipients who received appropriate anti-infective regimens turned negative eventually, and the patients were discharged successfully without significant complications.
Conclusion: Renal recipients with infections derived from DDs were at high risk of artery rupture, graft loss, or even death. Appropriate anti-infective treatment is essential to reduce the incidence of artery rupture and mortality.

Background: Granulomatosis with polyangiitis (GPA) is an autoimmune multisystem disorder characterized by small vessel vasculitis with granulomatous inflammation. In this report, we describe a unique case of GPA who presented with complete heart block (CHB) and developed complications due to intracranial large vessel involvement.
Case Summary: A 47-year-old gentleman presented with CHB with a background history of arthralgia and blood-tinged nasal discharge.

Background: Veno-arterial (V-A) extracorporeal membrane oxygenation (ECMO) is commonly used for patients with cardiac arrest, cardiogenic shock, or heart failure and is a life-saving technique. Computed tomography angiography (CTA) examination in patients on ECMO presents certain challenges. Due to the dual circulation characteristics of blood flow in ECMO patients, vascular imaging and interpretation can be difficult and may even present pitfalls.

Background: Flow diverters (FDs) have been introduced for the management of large or giant cavernous carotid aneurysms (CCAs) in addition to conventional modalities, dramatically changing treatment strategies. The aim of this study was to examine the management of unruptured large/giant CCAs in Japan when FDs were being introduced using a nationwide survey.
Methods: 540 unruptured large/giant CCAs treated at neurosurgical teaching departments in Japan between 2012 and 2016 were retrospectively studied.

Introduction: Retroperitoneal hematoma with ongoing hemorrhage is a rare but critical condition following blunt abdominal trauma, requiring urgent evaluation and management. This case details a large retroperitoneal hematoma in the right iliac fossa caused by a rupture of the deep circumflex iliac artery (DCIA), successfully treated with transcatheter arterial embolization.

Background And Objective: Cerebral aneurysms occur as balloon-like outpouchings in an artery, which commonly develop at the weak curved regions and bifurcations. When aneurysms are detected, understanding the risk of rupture is of immense clinical value for better patient management. Towards this, Fluid-Structure Interaction (FSI) studies can improve our understanding of the mechanics behind aneurysm initiation, progression, and rupture.
