Technique and impact on first pass effect primary results of the ASSIST global registry.

Background: Patients treated with mechanical thrombectomy (MT) for acute ischemic strokes from large vessel occlusion (LVO) have better outcomes with effective reperfusion. However, it is unknown which technique leads to better technical and clinical success. We aimed to determine which technique yields the most effective first pass reperfusion during MT.

Evaluation of effectiveness and safety of the CorPath GRX robotic system in endovascular embolization procedures of cerebral aneurysms.

Background: Robotic-assisted neurointervention was recently introduced, with implications that it could be used to treat neurovascular diseases.

Objective: To evaluate the effectiveness and safety of the robotic-assisted platform CorPath GRX for treating cerebral aneurysms.

Methods: This prospective, international, multicenter study enrolled patients with brain aneurysms that required endovascular coiling and/or stent-assisted coiling.

Effect of anesthetic strategies on distal stroke thrombectomy in the anterior and posterior cerebral artery.

Background: Numerous questions regarding procedural details of distal stroke thrombectomy remain unanswered. This study assesses the effect of anesthetic strategies on procedural, clinical and safety outcomes following thrombectomy for distal medium vessel occlusions (DMVOs).

Methods: Patients with isolated DMVO stroke from the TOPMOST registry were analyzed with regard to anesthetic strategies (ie, conscious sedation (CS), local (LA) or general anesthesia (GA)).

Aspiration Versus Stent Retriever Thrombectomy for Distal, Medium Vessel Occlusion Stroke in the Posterior Circulation: A Subanalysis of the TOPMOST Study.

Background: The optimal endovascular strategy for reperfusing distal medium-vessel occlusions (DMVO) remains unknown. This study evaluates angiographic and clinical outcomes of thrombectomy strategies in DMVO stroke of the posterior circulation.

Methods: TOPMOST (Treatment for Primary Medium Vessel Occlusion Stroke) is an international, retrospective, multicenter, observational registry of patients treated for DMVO between January 2014 and June 2020.

Rescue Maneuver of Migrated Coil Using the ERIC Device after Previous Attempts with Conventional Stentrievers.

Coil prolapse or migration is a rare but potentially serious complication that may occur during aneurysm embolization, with no standard management currently described. Here we describe our experience with the Embolus Retriever with Interlinked Cages (ERIC) device® (Microvention, Aliso Viejo, CA, USA) for the retrieval of prolapsed or migrated coils in a case series and Flow-Model analysis. First, a retrospective review was performed using our institution database for patients in which coil prolapse or migration occurred during aneurysm embolization, and data was collected and analyzed.

Smart glasses evaluation during the COVID-19 pandemic: First-use on Neurointerventional procedures.

The COVID-19 pandemic is rapidly transforming the healthcare system, with telemedicine, or virtual health, being one of the key drivers of the change. Smart glasses have recently been introduced to the public and have generated interest with healthcare professionals as demonstrated by their early adoption in clinics and hospitals. Observing procedures is essential for young interventionalist-in-training, but sometimes it is difficult for them to be able to get the volume of exposure to procedures that they need.

Upper extremity transvenous access for neuroendovascular procedures: an international multicenter case series.

Background: Radial artery access for transarterial procedures has gained recent traction in neurointerventional due to decreased patient morbidity, technical feasibility, and improved patient satisfaction. Upper extremity transvenous access (UETV) has recently emerged as an alternative strategy for the neurointerventionalist, but data are limited. Our objective was to quantify the use of UETV access in neurointerventions and to measure failure and complication rates.

Transcirculation Silk Vista Baby-assisted coiling in half-T configuration for the treatment of posterior communicating artery aneurysms associated with a fetal posterior circulation: An alternative flow diversion strategy.

Flow diverter devices have become a routine first-line option for treatment of an increasing population of intracranial aneurysms at many neurovascular centers. Despite the promising results of flow diverter stents on anterior circulation, incomplete occlusion on the presence of fetal posterior circulation has been described on several reports. Here we describe a novel technical alternative to conventional flow diversion approach for this specific subgroup of aneurysms using the low-profile flow diverter, Silk Vista Baby.

Arm-only access for combined transarterial and transvenous neurointerventional procedures.

A simultaneous arterial and venous approach has been widely described for the endovascular treatment of dural arteriovenous fistula (DAVFs) and recently for arteriovenous malformation (AVMs). Conventional venous approaches are performed by direct internal jugular puncture or by femoral access. Although complication rates are low, there are potential life-threatening complications that should be avoided.

Transcirculation Approach for Endovascular Embolization of Intracranial Aneurysms, Arteriovenous Malformations, and Dural Fistulas: A Multicenter Study.

Background: Unfavorable anatomy can preclude traditional anterograde endovascular interventions. Transcirculation approaches, which consist of primary catheterization of a target artery from the contralateral side or opposite cerebral circulation, can provide alternative pathways for successful treatment of these patients. We aimed to assess the safety, efficacy, and outcomes of endovascular embolization through transcirculation approaches.

A rare cause of emphysematous infectious gastritis.

A 61 year-old man with a history of hypertension, type2 diabetes, chronic renal failure, tuberculosis and peripheral arterial disease presented with gangrene in the right leg. A right supracondylar amputation was performed, despite which the patient continued with a high fever, oliguria and hypotension (90/50). Laboratory work-up showed neutrophilic leukocytosis and metabolic acidosis.
