BACKGROUND: Thromboembolic occlusion of distal branches in anterior and posterior circulation may produce severe clinical deficits. The ADAPT technique is a simple, fast method for achieving good angiographic and clinical outcomes using large bore catheters in large vessel occlusions. OBJECTIVE: We present our results using the ADAPT technique with distal cerebral artery occlusions. METHODS: Thirty-five patients with acute ischemic stroke with thrombus in the distal MCA, ACA, or PCA were treated with the ADAPT technique...

BACKGROUND: Our initial experience using the two-stage aspiration technique (TSAT) with proximal flow arrest by a balloon guiding catheter is presented. In TSAT, aspiration is applied with the 5MAX ACE and also with the 3MAX catheter with a Penumbra aspiration pump, while arresting proximal flow by balloon inflation. METHODS: In patients treated with TSAT, clinical data including National Institutes of Health Stroke Scale (NIHSS) score at admission and the modified Rankin Scale (mRS) score at discharge, as well as procedural data including the Thrombolysis in Cerebral Infarction (TICI) score, procedural time, and complications were analyzed...

Endovascular management of acute ischemic stroke secondary to septic emboli from bacterial endocarditis is case-specific and outside established guidelines. We report three new cases of an acute ischemic stroke secondary to septic embolus from two different centers. All cases reported here were large vessel occlusions of the middle cerebral artery in anticoagulated patients. In one case the embolus was noted to be firm and aspiration thrombectomy was attempted in lieu of stent retrieval. Thrombolysis in Cerebral Ischemia (TICI) 3 recanalization was achieved and the patient experienced a good outcome with resolution of deficits...

Background. Insufficient data are available on the potential benefit of selective aspiration and clinical predictors for no-reflow in STEMI patients undergoing primary percutaneous coronary intervention (PPCI) adjunct with aspiration thrombectomy. Objective. The aim of our study was to investigate clinical predictors for insufficient reperfusion in patients with high thrombus burden treated with PPCI and manual aspiration thrombectomy. Methods. From January 2011 till December 2015, 277 STEMI patients undergoing manual aspiration thrombectomy and PPCI were selected and 202 patients with a Thrombolysis in Myocardial Infarction (TIMI) thrombus grade 4~5 were eventually involved in our study...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

OBJECTIVE: Current percutaneous thromboembolectomy techniques may obviate surgical intervention in high-risk patients with iliocaval thrombus or thrombus of the right side of the heart, but typically require thrombus fragmentation and thrombolysis with associated bleeding and thromboembolic complications. The AngioVac (Angiodynamics, Latham, NY USA) device uses a percutaneous venovenous bypass circuit to aspirate intact thrombus. A review of the literature was performed with regard to the AngioVac device to determine the factors correlating with successful thrombus extraction...

OBJECTIVES: Hepcidin-25 serves as a key peptide in the regulation of iron homeostasis and inflammation. It remains unknown whether hepcidin-25 plays an adverse role in atherosclerotic diseases. The aim of this study was to investigate whether hepcidin-25 is involved in the pathophysiology of coronary plaque vulnerability. METHODS AND RESULTS: Serum hepcidin-25 levels were quantitatively determined by the LC-MS/MS assay system. Peripheral blood was collected from patients with acute myocardial infarction (MI, n=33) and patients with stable angina pectoris (sCAD, n=19)...

With the recent advent of suction catheters, the use of manual aspiration thrombectomy (MAT) for patients with acute ischemic stroke with large vessel occlusion has increased. Although contrast leakage and subarachnoid hemorrhage have been reported during MAT procedures, pseudoaneurysm formation due to vessel injury by suction catheters has not been. We discuss the case of a 60-year-old woman who presented to our emergency room with dysarthria and left-sided weakness. She underwent suction thrombectomy 5 times for acute middle cerebral artery occlusion and significant contrast leakage occurred during the procedure...

Limited data exist on the association between breast cancer treatments and coronary artery disease anatomy, particularly in males. We describe an unusual case of diffuse coronary ectasia in a man with breast cancer presenting with acute coronary syndrome (ACS). A 66-year-old man with breast cancer on paclitaxel, tamoxifen, and carboplatin chemotherapy regimen, presents with new onset chest pain. Electrocardiogram reveals anterolateral ST-segment depressions and elevated troponin I level. Emergent angiography revealed grossly ectatic coronary arteries with a total thrombotic occlusion of the mid right coronary artery...

BACKGROUND: The benefits of mechanical thrombectomy for emergent large vessel occlusion (ELVO) have been established. Combined mechanical/aspiration (Solumbra) and a direct aspiration as a first pass technique (ADAPT) are valid procedures requiring an intermediate catheter for clot suction. Recently, SOFIA (Soft torqueable catheter Optimized For Intracranial Access) was developed as a single lumen flexible catheter with coil and braid reinforcement, but its suitability for mechanical thrombectomy had not been evaluated...

INTRODUCTION: Tandem occlusion resulting in acute ischemic stroke (AIS) is associated with high morbidity and mortality and a poor response to thrombolytic therapy. The use of endovascular strategies for tandem stroke cases results in an improved outcome for this subgroup of patients. We present two cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques...

OBJECTIVES: The aim of this study was to evaluate if residual thrombus burden after aspiration thrombectomy affects the outcomes of primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Recent studies failed to show clinical benefit of aspiration thrombectomy in STEMI patients. This might be due to insufficient removal of thrombus at the culprit lesion. METHODS: A total of 109 STEMI patients who underwent aspiration thrombectomy followed by stenting within 24 h from symptom onset were included...

OBJECTIVE: The incidence of thrombus was investigated within retrievable filters placed in trauma patients with confirmed DVT at the time of retrieval and the optimal treatment for this clinical scenario was assessed. A technique called "filter retrieval with manual negative pressure aspiration thrombectomy" for management of filter thrombus was introduced and assessed. METHODS: The retrievable filters referred for retrieval between January 2008 and December 2015 were retrospectively reviewed to determine the incidence of filter thrombus on a pre-retrieval cavogram...

BACKGROUND: Vessel perforation during stent retriever thrombectomy is a rare complication; typically only single instances have been reported. OBJECTIVE: To report on a series of patients whose stent retriever thrombectomy was complicated by intraprocedural vessel perforation and discuss its potential mechanisms, rescue treatment strategies, and clinical significance. METHODS: Cases with intraprocedural vessel perforation, where a stent retriever was used either as a primary treatment approach or as a part of a direct aspiration first pass technique (ADAPT), were included in the final analysis...

The use of balloon guide catheters in acute ischemic stroke intervention has been associated with improved reperfusion rates and clinical outcomes. This technique acts by promoting flow arrest and subsequent reversal to capture the thrombus debris that may be generated during the clot retrieval process. However, to the best of our knowledge, the use of BGC to remotely aspirate and remove intracranial thrombus has not been previously described. We report a three case series of patients with acute ischemic stroke from supraclinoidal internal carotid artery occlusions treated with remote aspiration thrombectomy through a BGC placed at the cervical internal carotid artery, leading to complete reperfusion without the need for intracranial catheterization...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

Currently, the treatment of thromboembolic ischemia of the lower extremities includes percutaneous rotational thrombectomy and aspiration devices. However, the standard approach for endovascular treatment requires the administration of iodine contrast agents, which is problematic in patients with pre-existing renal disease and diabetes. Herein, we describe a case of a CO2 angiography guided endovascular thrombectomy of the superficial femoral artery (SFA) in a young patient with critical limb ischemia. Mechanical thrombectomy using the Rotarex system, catheter aided aspiration and subsequent stent placement in the SFA was entirely guided using CO2 angiography...
