We experienced a case of acute multiple organ ischemia and multiple organ failure due to atypical aortic coarctation (AAC). Since the patient's hemodynamics were too unstable to perform surgical revascularization, we performed urgent endovascular therapy (EVT) with a stent. ⋯ We feel that EVT for AAC is a sufficiently effective treatment option if the purpose of EVT is to save a patient's life in the acute phase. In the present case, spontaneous retroperitoneal bleeding (SRB) occurred after EVT of AAC, but this is a rare incident, although noteworthy in the clinical course.

Case Reports
Fracture of a Self-expandable Metallic Stent Inserted for Malignant Gastric Outlet Obstruction.
Duodenal stenting has gradually been established as the first-line treatment for malignant gastric outlet obstruction (GOO). We encountered a case of duodenal stent fracture in a 76-year-old woman with gastric cancer and GOO. ⋯ We removed the broken part of the stent and placed a second SEMS. SEMS fracture is a rare and - to the best of our knowledge - unreported complication; hence, clinicians and their patients should be aware of this possibility.

A 79-year-old man with lymphoma who tested negative for anti-hepatitis C virus (HCV) antibody received rituximab-containing chemotherapy. Liver dysfunction of unknown cause had persisted since the second cycle of chemotherapy. ⋯ Furthermore, medical interviews showed that the patient had no episodes for acute HCV infection, but he did have a history of unspecified liver dysfunction. These findings support the possibility of the reactivation of seronegative occult HCV infection due to chemotherapy in a cancer patient.

Most cases of mediastinal abscess occur as a postoperative complication of a thoracic surgical procedure or following trauma. The most common causative microorganism is Staphylococcus aureus, but it can be rarely caused by unusual microorganisms, such as Gemella species. ⋯ He was successfully treated with penicillin antibiotic for eight weeks. To our knowledge, this is the first case report of mediastinal abscess caused by G. bergeri.

Case Reports
Spontaneous Pyogenic Spondylitis and Possible Infective Endocarditis Caused by Aggregatibacter actinomycetemcomitans.
Aggregatibacter actinomycetemcomitans, an etiological agent associated with periodontitis, endocarditis, and other infections, has rarely been implicated in spondylitis. A 70-year-old man with aortic valve replacement presented with a 4-month history of lower back pain and was diagnosed with spondylitis. Prolonged incubation of blood cultures and a biopsy yielded A. actinomycetemcomitans. ⋯ The patient was treated with ceftriaxone and recovered well. Pyogenic spondylitis with possible concurrent IE may be caused by A. actinomycetemcomitans. Extended incubation and repeated cultures should be considered if Haemophilus spp., Aggregatibacter spp, Cardiobacterium spp, Eikenella spp, and Kingella spp. (HACEK) infection is suspected.
