Is there still a place for thrombectomy?

Advances in Interventional Cardiology, 2016
Malignancy is known to be a prothrombotic condition, and some antitumor drugs may amplify the hypercoagulable tendency. We present a female patient with cancer, who developed acute coronary syndrome (ACS) due to occlusive intracoronary thrombus without underlying atherosclerosis.

Endovascular Thrombectomy for Acute Basilar Artery Occlusion: A Multicenter Retrospective Observational Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Despite the recent acceptance of thrombectomy as the standard of care in patients with acute anterior circulation stroke, the benefits of thrombectomy remain uncertain for patients with acute basilar artery occlusion (BAO). This study aimed to

Self-sensing with hollow cylindrical transducers for histotripsy enhanced aspiration mechanical thrombectomy applications [PDF]

arXiv
To address existing challenges with intravascular mechanical thrombectomy devices, a novel ultrasound-enhanced aspiration approach is being developed to mechanically degrade clots using cavitation. This method employs standing waves within a mm-scale hollow cylindrical transducer to generate high pressures sufficient to perform histotripsy on clots ...

Measuring Direct Oral Anticoagulant (DOAC) Levels: Applications, Limitations, and Future Directions

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction There are important challenges with the measurement and interpretation of direct oral anticoagulant (DOAC) anticoagulant effect including a lack of therapeutic ranges, inaccuracy of routinely available coagulation assays, lack of established thresholds for clinically significant effect, and uncertainty about how to apply the ...

The role of friction forces in arterial mechanical thrombectomy: a review [PDF]

arXiv
Multiple clinical trials have demonstrated the superiority of mechanical thrombectomy (MT) in treating acute ischemic stroke (AIS). Stent retriever (SR) and aspiration techniques are the standard methods for removing occluded emboli, with evolving technologies improving MT efficiency. However, procedural success remains uncertain.

Nomogram for Deep Vein Thrombosis Prediction Post‐Endovascular Thrombectomy in Acute Ischemic Stroke: A Retrospective Multicenter Observational Study

Journal of Clinical Nursing, EarlyView.
ABSTRACT Background Deep vein thrombosis (DVT) is a frequent complication following endovascular thrombectomy (EVT) in patients with acute ischaemic stroke (AIS), potentially leading to fatal pulmonary embolism (PE). Identifying patients early at high risk for DVT is clinically important.

A dual-task mutual learning framework for predicting post-thrombectomy cerebral hemorrhage [PDF]

arXiv
Ischemic stroke is a severe condition caused by the blockage of brain blood vessels, and can lead to the death of brain tissue due to oxygen deprivation. Thrombectomy has become a common treatment choice for ischemic stroke due to its immediate effectiveness. But, it carries the risk of postoperative cerebral hemorrhage.

Simultaneous whole‐brain and cervical spine imaging at 7 T using a neurovascular head and neck coil with 8‐channel transceiver array and 56‐channel receiver array

Magnetic Resonance in Medicine, Volume 94, Issue 1, Page 386-400, July 2025.
Abstract Purpose To develop a 7T neurovascular head and neck (NVHN) coil with an extended longitudinal coverage of the brain and cervical spine, with eight transceiver (TxRx) channels and 56 receive (Rx) channels for dynamic parallel‐transmit (pTx) applications. Methods A dual‐row transceiver array with six elements in the upper row and two elements in
