Historical innovations in mechanical thrombectomy devices and strategies for ischemic stroke have resulted in improved angiographic outcomes and better clinical outcomes. Various devices have been used, but the two most common approaches are aspiration thrombectomy and stent-retrieval thrombectomy. Aspiration thrombectomy has advanced from the traditional Penumbra system to forced arterial suction thrombectomy and a direct aspiration first-pass technique. Newer generation aspiration catheters with flexible distal tips and a larger bore have demonstrated faster and better recanalization relative to older devices...

BACKGROUND: The most essential development in endovascular stroke treatment (EST) was the shift from intra-arterial thrombolysis to endovascular thrombectomy with dedicated thrombectomy devices, most notably the introduction of stent-retrievers. We evaluated procedural and clinical effectiveness and safety of different EST techniques over time. METHODS: We retrospectively analyzed EST cases that were treated by the same interventionalist before (n=36) and after (n=50) stent-retrievers were established as the treatment device of first choice...

The endovascular treatment of acute ischemic stroke has become a standard procedure. The combination of multiple neuroendovascular devices provides more possibilities for the improvement of the thrombectomy technique. We describe a modified retrieval technique using a distal intracranial catheter (DIC) for the semi-retrieval of stentriever during the thrombectomy procedure. The retrograde semi-retrieval technique involves completely unfolding the stent retriever by pulling a Navien catheter and the partial re-sheath of a retrievable stent forming a tapered configuration by pushing the Navien catheter, which results in the thrombi being embedded into the strut, securing the clot within the stent and there being a shorter distance for the clot to travel...

Intracranial high-resolution vessel wall magnetic resonance imaging evidence of vessel wall inflammation is present following stent retriever manipulation but absent following aspiration thrombectomy. This is presented in a case of rotatory vertebral artery compression causing multiple posterior circulation infarctions requiring multiple separate aspiration and stent retriever thrombectomies.

A 52-year-old Asian male with no traditional risk factors for coronary artery disease presented with acute coronary syndrome. Coronary angiography showed complete thrombotic occlusion of the left circumflex with a large thrombus burden in the setting of diffuse aneurysmal enlargement of the coronary arteries consistent with antecedent Kawasaki disease. Manual thrombectomy with adjunctive intracoronary tirofiban was performed utilizing the GuideLiner catheter. Stent implantation was deferred. Follow-up imaging 48 h later showed preserved coronary flow and decreased thrombus burden...

Venous thromboembolism (VTE) is an extremely common form of vascular disease and impacts a great number of patients worldwide. Acute deep vein thrombosis (DVT) is a subset of VTE and is traditionally been treated with anticoagulation. There is good quality data which suggests the use of catheter directed interventions for the treatment of acute DVT with the aim of reducing post-thrombotic syndrome (PTS). The present review will discuss the various therapies available for acute DVT, focusing on catheter directed interventions, ranging from traditional anticoagulation to the most novel forms of aspiration thrombectomy...

RATIONALE: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. CAE is often associated with the presence of slow coronary flow and may lead to acute myocardial infarction (AMI), even without total occlusion. PATIENT CONCERNS AND DIAGNOSIS: We report a case of a 24-year-old male patient with CAE suffering from AMI. INTERVENTIONS: Percutaneous coronary intervention with aspiration thrombectomy failed to restore adequate blood flow...

PURPOSE: We report a combined technique consisting of thrombectomy and thromboaspiration for the treatment of acute embolic occlusion of the superior mesenteric artery (SMA) at the origin. CASE: A 90-year-old female with chronic atrial fibrillation had a sudden onset of abdominal pain and hematochezia due to acute embolic occlusion at the origin of the SMA. Computed tomographic findings showed reversible bowel wall ischemia. We performed mechanical thrombectomy using the Solitaire FR revascularization device, a self-expanding and fully retrievable stent-based thrombectomy system for acute intracranial large artery occlusion, combined with manual aspiration through a 6F guiding sheath placed at the SMA origin via a right brachial approach...

Modern, minimally invasive techniques used to treat deep venous thrombosis, such as percutaneous mechanical thrombectomy (PMT) and catheter-directed thrombolysis, have gained worldwide acceptance. PMT has the advantage of speed and is also associated with improved outcomes, shortened hospital stays, and low complication rates. The main complications associated with PMT have been primarily due to iatrogenic vascular damage resulting in perforation, embolic occlusion, and arteriovenous fistula formation; to date, there has been no publication in the literature describing complications resulting from device failure...
