Endovascular neurointervention in Iraq: Realistic obstacles, a hopeful start with “Al-Hayat center” Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-02-13 Ghazwan A Lafta
Endovascular neurointervention nowadays plays an important role in the effective treatment of different head and neck vascular pathologies using minimally invasive means. In Iraq, until recently, endovascular neurointervention field is nearly absent. A new hope was started when an advanced neurointerventional center was created to improve and develop this field in Iraq.

Experimental evaluation of the plunger technique: A method of cyclic manual aspiration thrombectomy for treatment of acute ischemic stroke Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-02-07 Demitria A Poulos, James S Keith, Michael T Froehler, Bryan C Good
BackgroundMechanical thrombectomy via direct aspiration is a rapid treatment for acute ischemic stroke. This method often results in the partial ingestion of the clot or “corking” of the catheter tip. Cyclic aspiration may take advantage of the mechanical properties of the clot, resulting in greater clot ingestion and overall procedure success.MethodsAn in vitro analysis was performed comparing static

A rare dissecting anterior inferior cerebellar artery aneurysm treated with flow diversion using a silk vista baby device Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-01-24 Omar Kass-Hout, Ziad Darkhabani, Tibor Becske
BackgroundDissecting intracranial pseudoaneurysms represent a challenge for treatment both endovascularly and surgically.MethodsWe review the treatment course of a ruptured anterior inferior cerebellar artery (AICA) dissecting pseudoaneurysm in a 50-year-old patient and review the history of dissecting aneurysms and AICA aneurysms treatment.ResultsAn aneurysm cure was achieved using flow diversion

Patients’ perceptions on outcomes after mechanical thrombectomy in acute ischemic stroke Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-01-23 Shail Thanki, Elliot Pressman, Kassandra M Jones, Ruby Skanes, Ahmad Armouti, Waldo R Guerrero, Kunal Vakharia, Ashwin B Parthasarathy, Kyle Fargen, Eva A Mistry, Shahid M Nimjee, Ameer E Hassan, Maxim Mokin
BackgroundThe modified Rankin Scale (mRS) is a clinician-reported scale that measures the degree of disability in patients who suffered a stroke. Patients’ perception of a meaningful recovery from severe stroke, expected value of a stroke intervention, and the effect of disparities are largely unknown.MethodsWe conducted a survey of patients, their family members, and accompanying visitors to understand

Overestimation of ischemic core on baseline MRI in acute stroke Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-01-23 MA McArthur, E Tavakkol, M Bahr-Hosseini, R Jahan, GR Duckwiler, JL Saver, DS Liebeskind, K Nael
Background and PurposeIn patients with acute ischemic stroke (AIS), overestimation of ischemic core on MRI-DWI has been described primarily in regions with milder reduced diffusion. We aimed to assess the possibility of ischemic core overestimation on pretreatment MRI despite using more restricted reduced diffusion (apparent diffusion coefficient (ADC) ≤620 × 10−6 mm2/s) in AIS patients with successful

Balloon-assisted U-turn Technique to Access Cortical Vein for Transvenous Embolization of Mixed Dural-pial Arteriovenous Malformation Interv. Neuroradiol. (IF 1.7) Pub Date : 2024-01-16 Muhammed Amir Essibayi, Dhrumil Vaishnav, Ryan Holland, David J Altschul
Cerebral arteriovenous malformations can be classified into pure pial, mixed dural-pial, and pure dural types. Mixed pial-dural AVMs (DPAVM) are rare and often receive blood supply from dural meningeal arteries, including branches of the internal carotid, external carotid, and vertebral arteries. 1 – 6 DPAVMs, which are usually large and complex, require delicate endovascular and surgical treatment
