REcanalisation and Balloon-Oriented Puncture for Re-Insertion of Dialysis Catheter in Nonpatent Central Veins (REBORN).
To describe a technique involving REcanalisation and Balloon-Oriented puncture for Re-insertion of dialysis catheter in Nonpatent central veins (REBORN) and to report long-term results. ⋯ The REBORN technique allows for the preservation of central veins for future haemodialysis access, which can be challenging in patients requiring long-term dialysis.

Case ReportsA Case of Ruptured Aneurysm of the Proper Esophageal Artery with Symptomatic Mediastinal Hematoma.
Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. ⋯ Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.

Intraarticular Sacroiliac Joint Injection Under Computed Tomography Fluoroscopic Guidance: A Technical Note to Reduce Procedural Time and Radiation Dose.
A technique for computed tomography fluoroscopy (CTF)-guided intraarticular (IA) sacroiliac joint (SIJ) injection was devised to limit procedural time and radiation dose. ⋯ Given the high rate of technical success achieved in limited time duration and with little radiation exposure, CTF-guided IA SIJ injection is a practical and low-risk procedure.

Gallbladder Cryoablation: Proof of Concept in a Swine Model for a Percutaneous Alternative to Cholecystectomy.
To investigate the feasibility of percutaneous gallbladder cryoablation (GBC) under CT guidance in a swine model with histopathologic correlation. ⋯ Percutaneous gallbladder cryoablation is feasible, with adequate ablation margins obtained and histologic changes demonstrating transmural necrosis. Adjacent structures included in the ablation may require conservative ablation zones, hydrodissection, or continuous saline lavage.

Arterial Embolization in the Management of Mesenteric Bleeding Secondary to Blunt Abdominal Trauma.
Mesenteric bleeding is a rare but potentially life-threatening complication of blunt abdominal trauma. It can induce active hemorrhage and a compressive hematoma leading to bowel ischemia. Emergency laparotomy remains the gold standard treatment. We aimed to study the effectiveness and complications of embolization in patients with post-traumatic mesenteric bleeding. ⋯ In mesenteric trauma with active bleeding, embolization is a valuable alternative to surgery and should be considered, taking into account the risk of bowel ischemia.
