Bladder Artery Embolization for Massive Hematuria Treatment in a Patient With Ataxia-Telangiectasia Acute Lymphoblastic Leukemia.

Ataxia-telangiectasia (AT) is a hereditary recessive autosomal disorder following a course of progressive cerebellar ataxia, and oculocutaneous telangiectasia. Disease-specific telangiectasias are generally localized in the oculocutaneous region, while telangiectasias located within the bladder are rarely seen in patients with AT. The patient who had been followed-up with a diagnosis of AT since the age of 3 years was later diagnosed with acute lymphoblastic leukemia at the age of 8 years.

Treatment of posterior inferior cerebellar artery aneurysms using flow-diverter stents: A single-center experience.

Introduction: The effectiveness and reliability of flow-diverter stents, which are commonly used in aneurysms of the anterior circulation, have been demonstrated previously. However, the use of these devices is associated with higher rates of perforator and branch ischemia following the treatment of aneurysms of the posterior circulation.

Methods: This work involved a single-center; retrospective study reviewing eight patients who had aneurysms related to the posterior inferior cerebellar artery (PICA) and who were treated with flow-diverter stents from September 2013 to May 2017.

A back and forth manual aspiration technique using a SOFIA Plus catheter for acute ischemic stroke: technical note.

Purpose: We describe a new modification of thromboaspiration to facilitate recanalization, referred to as the "back and forth" manual aspiration technique.

Methods: In this technique, the aspiration catheter (SOFIA Plus catheter, MicroVentionInc, Tustin, CA, USA) is positioned adjacent to the occluded segment and then advanced over the thrombus during manual aspiration with a 50-cc syringe.

Results: We evaluated this technique in 15 patients who presented to our institution with acute ischemic stroke (AIS).

Selective Arterial Embolization of Giant Renal Angiomyolipoma Associated with Tuberous Sclerosis Complex Using Particular and Liquid Embolic Agents.

Renal angiomyolipoma (AML) is a benign hamartomatous tumor that is sometimes associated with the tuberous sclerosis complex. We report a 23-year-old man who presented with acute abdominal pain and hematuria. Computed tomography (CT) revealed large heterogeneous right renal mass of 17×13×13-cm diameter, consistent with AML, and acute and subacute hemorrhages.

Enhancing Hepatic Microcirculation in Postoperative Hepatic Failure With Intra-arterial Recombinant Tissue Plasminogen Activator Treatment.

Postoperative hepatic failure is one of the most severe complications after liver resection. Treatment protocols have varied from medical support to liver transplant. Here, we describe the clinical course of an 18-year-old female patient with postoperative hepatic failure.

Endovascular embolization in the management of traumatic and postoperative abdominopelvic bleeding: a single-center experience.

Background/aim: Endovascular embolization is widely used instead of surgery in the treatment of traumatic and postoperative abdominopelvic bleeding. The objective of this study is to evaluate the efficiency of computed tomography in the determination of active bleeding and the efficiency of endovascular embolization in traumatic and postoperative abdominopelvic bleeding. Materials and methods: Thirty-one patients admitted to our hospital with traumatic and postoperative abdominopelvic bleeding between January 2006 and September 2012 and treated with endovascular embolization were retrospectively enrolled in the study.

Mechanical removal of a refluxed Onyx piece from the middle cerebral artery using the Solitaire Stent: Technical report.

Onyx reflux into the parent artery is a rare and sometimes significant complication in the treatment of cerebral arteriovenous malformations (AVMs). We report a patient who presented with Onyx reflux into the M1 segment of the middle cerebral artery (MCA) during embolization of a right temporal AVM. The refluxed Onyx cast was successfully removed by a mechanical thrombectomy device using a self-expandable and fully retrievable Solitaire AB stent.

A novel technique in the treatment of retroperitoneal lymphatic leakage: direct percutaneous embolization through the leakage pouch.

Lymphangiography and percutaneous embolization of injured lymphatics are minimally invasive and effective techniques for the diagnosis and treatment of thoracic and retroperitoneal lymphatic leaks. We present a 58-year-old man who had abdominal chylous collection developed after multiple abdominal surgeries. Retroperitoneal lymphatic duct leakage was detected by ultrasound-guided intranodal lymphangiography and treated successfully using computed tomography (CT)-guided transabdominal embolization with percutaneous N-butyl cyanoacrylate (NBCA) glue and percutaneous NBCA glue and coil embolization by directly catheterizing the leaking lymphatic channel through the chylous collection.

Preoperative arterial embolization of large liver hemangiomas.

Purpose: We aimed to investigate the efficacy and safety of preoperative selective intra-arterial embolization (PSIAE) in the surgical treatment of large liver hemangiomas.

Methods: Data of 22 patients who underwent resection of large liver hemangiomas were retrospectively analyzed. PSIAE was performed in cases having a high risk of severe blood loss during surgery (n=11), while it was not applied in cases with a low risk of blood loss (n=11).

[Percutaneous endovascular removal of intracardiac migrated port A catheter in a child with acute lymphoblastic leukemia].

A 2-year-old boy with acute lymphoblastic leukemia was presented with peripherally inserted central catheter dysfunction.
