A case of acquired thrombotic thrombocytopenic purpura following near-drowning.

A 19-year-old woman with a history of asthma presented with acute confusion following a near-drowning event 2 weeks prior to admission. She was found to have severe thrombocytopenia and microangiopathic hemolytic anemia (MAHA). The treatment for thrombotic thrombocytopenic purpura (TTP) was started on the day of admission due to high clinical suspicion. Subsequent workup confirmed a diagnosis of TTP with no clear etiology except the near-drowning incident. TTP following a near-drowning event has never been reported in the literature. Furthermore, she developed refractory TTP that required reinitiation of therapeutic plasma exchange and rituximab. After discharge, the patient had been doing well over a year of follow-up without remission.

Percutaneous arteriovenous fistula creation in the management of severe Hemophilia A and end-stage kidney disease needing hemodialysis access, and beyond.

With the contemporary KDOQI, a patient-focused approach in vascular access care is emphasized more than ever when planning RRT. Nevertheless, functional vascular access continues to be the Achilles' heel for successful hemodialysis in specific patient sub-groups, such as the Hemophilia-A population. The newer percutaneous endovascular approach is a safer alternative when conventional surgical AVF poses high bleeding risks perioperatively, which subsequently prevents ESKD patients to have desired permanent dialysis access. This article presents the case of a 45-year-old male with severe Hemophilia-A, who has been dialysis-dependent due to diabetic kidney disease and hypertension. Due to the severity of his progressively worsening bleeding disorder, his previous surgeries to treat other comorbidities have been complicated and involved challenging peri-operative treatment courses that include blood and factor VIII infusions, bleeding wounds, along with prolonged hospital stays. With the fear of bleeding diathesis, a conventional surgical AVF was not pursued, which has left him with a prolonged tunneled CVC while not being considered a candidate for peritoneal dialysis. We offered the patient a left arm percutaneous endovascular AVF creation with the WavelinQ™ 4F Endo-AVF system as an alternative option for his permanent hemodialysis access. An Endo-AVF was created bloodlessly between the left radial artery and lateral radial vein percutaneously with only two 4-French accesses at left wrist. The patient has been receiving full sessions of hemodialysis with expected flow rates and free of the CVC since. Likely the first case of such utilization reported, the utilization of percutaneous Endo-AVF for this patient has suggested not only that the endovascularly created AVF offers a good alternative dialysis access for hemophilia A patient populations, but also due to this technology's unique features, it can be potentially employed in other situations, such as needs for reliable and chronic venous accesses and blood product exchanges.
