Mechanical thrombectomy with a novel beveled tip aspiration catheter: A technical case report.

Recent data suggested aspiration thrombectomy as the first-pass approach in endovascular treatment of acute stroke and is accepted as a safe and efficient alternative to stent-retriever thrombectomy. The efficiency of mechanical thrombectomy for complete removal of the clot is directly related to the catheter trackability, aspiration force, and inner diameter of the aspiration catheter. Zoom 71 Aspiration catheter (Imperative Care, Campbell, California, USA) is a novel aspiration catheter with a beveled tip aiming to increase the tip surface area, increased suction force, and advanced trackability.

Asymmetrically severe internal auditory canal hypoplasia: A case report.

We present a case of an otherwise healthy 20-month-old with congenital sensorineural hearing loss. CT and MR imaging demonstrated bilateral asymmetrically severe hypoplasia of the internal auditory canals and vestibulocochlear nerves. Additional developmental inner ear anomalies were present in this patient, including unilateral semicircular canal hypoplasia and suspected bilateral cochlear hypoplasia.

Predictive value of platelet-to-lymphocyte ratio in severe degenerative aortic valve stenosis.

Background: Aortic valve stenosis (AVS) is the most common cause of left ventricular outflow obstruction, and its prevalence among elderly patients causes a major public health burden. Recently, platelet-to-lymphocyte ratio (PLR) has been recognized as a novel prognostic biomarker that offers information about both aggregation and inflammation pathways. Since PLR indicates inflammation, we hypothesized that PLR may be associated with the severity of AVS due to chronic inflammation pathways that cause stiffness and calcification of the aortic valve.

Endovascular Treatment of Thrombosis and Embolism.

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation.

Mechanical Removal of Migrated Onyx Due to Microcatheter Rupture During AVM Embolization: A Technical Case Report.

We report a case where migrated Onyx could be removed safely with a mechanical thrombectomy device after withdrawal of the damaged microcatheter. A microcatheter was retained in the superior cerebellar artery with attached Onyx fragments on its tip during embolization of a bled cerebellar AVM. During retrieval maneuvers microcatheter shaft was ruptured and Onyx fragments were released into the vertebrobasilar system causing occlusion.

Endovascular treatment of cervical giant perimedullary arteriovenous fistulas.

Background: Giant perimedullary arteriovenous fistulas (GPMAVFs) located in the cervical region are a rare pathology with distinctive characteristics.

Objective: To evaluate clinical presentation and different endovascular treatment options of cervical GPMAVFs and review previously published data in the literature regarding cervical GPMAVFs.

Methods: Six patients with cervical GPMAVFs were found in the spinal vascular malformations database of our group collected between 1990 and 2009.

Looking for the ideal particle: an experimental embolization study.

This study sought to compare the most frequently used embolic particles in an animal model. In 16 New Zealand white rabbits, right renal arteries were embolized using four different embolic particles (polyvinyl alcohol [PVA] particles, 150-250 microm; PVA microspheres [PVAMs], 150-300 microm; Tris-acryl gelatin microspheres [TGMs], 100-300 microm; expanding microspheres [EXMs], 50-100 microm). Quantity of embolic material used, embolization time, and angiographic patterns were documented.

Publication rates of scientific presentations in Turkish national radiology congresses.

Purpose: To investigate the publication rates of scientific presentations in Turkish radiology congresses.

Materials And Methods: The abstracts of presentations at Turkish national radiology congresses between 1995-2002 were reviewed. According to the congress abstract booklets, types of the presentation (oral or poster presentation), as well as body system-based categorization were used.
