Brain damage evaluation via arterial spin labeling perfusion imaging for patients with aneurysmal subarachnoid hemorrhage.

Objective: Subarachnoid hemorrhage (SAH) is a neurological condition with an annual incidence of 6-22 per 100,000. Despite many advances in diagnosis, the rates of mortality and morbidity in patients remain high. The most important reason for this is complications accompanied by perfusion changes.

The role of liver resection in the management of severe blunt liver trauma.

Background: The management of hepatic trauma has a historical progress from mandatory operation with selective non-operative treatment, to non-operative treatment with selective operation. Liver resection (LR) seems to have a minimal role in the management of liver injury. However, surgical treatment becomes the only life-saving treatment in cases with severe liver trauma.

Can diffusion weighted imaging be used as an alternative to contrast-enhanced imaging on magnetic resonance enterography for the assessment of active inflammation in Crohn disease?

The present study aimed to investigate the potential use of T2-weighted sequences with diffusion weighted imaging (DWI) in magnetic resonance (MR) enterography instead of conventional contrast-enhanced MR imaging (MRI) sequences for the evaluation of active inflammation in Crohn disease.Two-hundred thirteen intestinal segments of 43 patients, who underwent colonoscopy within 2 weeks before or after MR enterography were evaluated in this retrospective study. DWI sequences, T2-weighted sequences, and contrast-enhanced T1-weighted sequences were acquired in the MR enterography scan after cleaning of the bowel and using an oral contrast agent.

This study aimed to identify the role, efficacy and safety of pelvic arterial embolisation (PAE) in the management of massive vaginal haemorrhage occurring in 25 patients with obstetric and gynaecological emergencies where bleeding could not be controlled by conservative treatment methods. Nine of the cases had disseminated intravascular coagulation (DIC) and eight were haemodynamically unstable. PAE was successful in 23 of 25 patients without any major complication.

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.

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 Treatment of Very Rare Anomaly; Breast Pseudoaneurysm Developed During Pregnancy.

Pseudoaneurysms (PA) in the arterial supply of the breast are quite rare and mostly iatrogenic secondary to biopsies. Breast PAs after blunt trauma is even rarer. In this paper, a case of breast PAs secondary to blunt trauma and its percutaneous treatment using human thrombin injection and after N-butyl cyanoacrylate is presented.

Role of 3D power Doppler ultrasound in the further characterization of suspicious breast masses.

Purpose: To investigate effectiveness of vascular indices obtained with 3D power Doppler ultrasound in the further characterization of breast masses and prevention of unnecessary biopsies.

Materials And Methods: Between April 2013 and March 2014, 109 patients (age range, 17-85 years; mean age, 47 years) with 117 radiologically or clinically suspicious breast masses were prospectively evaluated with 3DPDUS before biopsy. Mass volume (MV), vascularization index (VI), flow index (FI) and vascularization flow index (VFI) were calculated using Virtual Organ Computer-aided Analysis (VOCAL) software and they were correlated with the final diagnosis.

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.
