AI Article Synopsis
- Randomized studies have limited the use of aspiration thrombectomy in myocardial infarction to specific cases, while mechanical thrombectomy for stroke has advanced significantly due to different underlying causes.
- Three successful transradial procedures using neurointerventional catheters demonstrate their effectiveness in removing large clots in complex coronary anatomy without complications.
- Neurointerventional catheters are recommended as a backup option for large clots, offering benefits like a larger aspiration lumen and better maneuverability, potentially improving the safety and effectiveness of thrombus aspiration techniques.
Article Abstract
Unlabelled: Due to the negative results of randomized aspiration thrombectomy studies, its role in myocardial infarction has been limited to high thrombus burden and/or failed vessel recanalization, with little technological advancement over the last years. In contrast, there has been rapid progress in mechanical thrombectomy in stroke, which is understandable as most ischemic cerebrovascular accidents have an embolic etiology.We present three transradial procedures wherein neurointerventional catheters were used as a first-line device for removal of large clots lodged distally in tortuous coronary anatomy. First-pass reperfusion was achieved in all the cases, without dissection, distal embolization, or the no reflow phenomenon.
Learning Objective: In the case of large clots, where coronary aspiration devices fail, neurointerventional catheters may be considered as a rescue strategy. They provide large aspiration lumen and excellent trackability with atraumatic design. Many other neurointerventional techniques can be easily adopted into the coronary armamentarium, possibly increasing the safety and efficacy of thrombus aspiration.

Tenzing Assisted Delivery of Aspiration (TADA) technique for thrombectomy of medium vessel occlusions using the Freeclimb 54 catheter: multicenter experience.
J Neurointerv Surg
January 2025
Radiology, Auckland City Hospital, Auckland, New Zealand.
Background: Medium vessel occlusions (MeVOs) account for 25-40% of acute ischemic stroke. The Tenzing 5 (Route 92 Medical, San Mateo, California, USA) and FreeClimb 54 (Route 92 Medical, San Mateo, California, USA) catheter is a novel delivery-aspiration catheter combination designed to facilitate aspiration thrombectomy (AT) of MeVOs. We report our clinical experience using the Tenzing assisted delivery of aspiration (TADA) technique with FreeClimb 54 for first-line AT of MeVO.

Background: The elderly population (≥80 years) were underrepresented in recent trials of endovascular thrombectomy (EVT) for anterior circulation large vessel occlusion acute ischemic stroke (LVO-AIS) with low Alberta Stroke Program Early CT Score (ASPECTS) (≤5).
Methods: This study analyzed data from a prospectively maintained database of 37 thrombectomy centers. The primary cohort of the study comprised patients with LVO-AIS aged ≥80 who underwent EVT with ASPECTS≤5 from 2013 to 2023.
Management of Anterior Choroidal Artery Aneurysms: A Retrospective Cohort Study.

Division of Neurointerventional Radiology, UMass-Chan Lahey Department of Radiology, Lahey Hospital and Medical Centre-Beth Israel Lahey Health, Burlington, MA 01805, USA.
Anterior choroidal artery (AChoA) aneurysms pose a challenge for both endovascular and clipping procedures. The eloquent territory supplied by the parent vessel has limited collateralization and its compromise can lead to significant morbidity. This study aims to analyze the clinical outcomes and procedure-related complications of clipping and endovascular treatment of AChoA aneurysms to aid physician decision making.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Background And Purpose: The safety and effectiveness of endovascular techniques in elderly patients with large vessel occlusion (LVO) remain controversial. We investigated the angiographic and clinical outcomes of nonagenarians treated with different endovascular techniques using a balloon guide catheter (BGC), distal aspiration catheter (DAC), and/or stent retriever (SR).
Methods: We analyzed the data from the Registry of Combined versus Single Thrombectomy Techniques (ROSSETTI) of consecutive nonagenarian patients with anterior circulation LVO and compared the outcomes of those treated with BGC+noDAC+SR (101-group), BGC+DAC+SR (111-group), and noBGC+DAC+SR (011-group).
