[Subdural Hematoma after Open Heart Surgery for Infective Endocarditis Presenting with Pre-operative Intracranial Hemorrhage Infarction;Report of a Case]

A 47-year-old woman with a history of radiation enteritis and implantation of a central venous port was admitted to our intensive care unit(ICU) suffering from high fever. She was diagnosed with active infective endocarditis due to catheter-related blood stream infection. Although echocardiography showed a large vegetation on the mitral valve, surgical therapy was postponed for 5 weeks because of intracranial hemorrhage infarction. On the 3rd day after mitral valve repair, she developed consciousness disturbance and computed tomography(CT) revealed acute subdural hematoma of the posterior cranial fossa. Fortunately, she fully recovered from the neurological complication without surgical intervention.

Rupture of Subcutaneous Peritoneal Dialysis Catheter by Stretching Exercise: A Case Report

Rupture of the peritoneal dialysis (PD) catheter is rare complication. Here, we report a case of catheter rupture that occurred because of exercise after partial catheter reimplantation.A 66-year-old man with a history of end-stage kidney disease secondary to diabetic nephropathy experienced refractory exit-site and tunnel infection. After the infected parts of the catheter were excised, a partial catheter reimplantation was performed. At the time of that surgery, a presternal location was selected for the new exit site, and a titanium extender was used to connect the two catheters. The patient was discharged on postoperative day 3, but was readmitted for a pericatheter leak 5 days later. Fluoroscopy performed to investigate the cause demonstrated a pericatheter leak from the connecting portion between the titanium extender and the catheter.Surgery performed to repair the leak revealed that the catheter had ruptured. We believe that the cause of the rupture was mechanical stress induced by the patient's stretching exercise program. The PD catheter was made of silicone rubber with high elasticity. Even when such resilient materials are used, we recommend that, to avoid PD catheter rupture after partial reimplantation, clinicians should discourage the patient from stretching excessively.

[Thoracic epidural abscess without neurological deficits]

This case report describes a patient, who had a thoracic epidural abscess without neurological deficits. The patient had epidural analgesia due to a flail chest trauma. After 14 days he developed radicular pain during bolus injection through the catheter, as well as fever and elevated white cell count and C reactive protein. An acute magnetic resonance imaging revealed a thoracic epidural abscess. The initial treatment was high dose antibiotic therapy followed by an acute surgical laminectomy. The patient never developed any neurological signs and was kept on high dose oral opioids and gabapentin in order to secure sufficient analgesia.
