Chronic post-thrombotic obstruction of the inferior vena cava (IVC) or iliocaval junction is an uncommon complication of long indwelling IVC filter. When such an obstruction is symptomatic, endovascular treatment options include stent placement with or without filter retrieval. Filter retrieval becomes increasingly difficult with longer dwell times. We present a case of symptomatic post-thrombotic obstruction of the iliocaval junction related to Günther-Tulip IVC filter (Cook Medical Inc, Bloomington, IN) with dwell time of 4753 days, treated successfully with endovascular filter removal and stent reconstruction...

BACKGROUND AND PURPOSE: Thrombolysis in cerebral infarction (TICI) with 2b/3 (>50% of occluded territory/complete reperfusion) has been regarded as a successful angiographic outcome. To account for near-perfect angiographic results, the category TICI 2c (near-complete reperfusion) has been introduced. As the degree of inter-rater reliability for TICI with 2c category remains poorly studied, we strived to evaluate the agreement among stroke-treating specialists. METHODS: All consecutive patients, who underwent stent-retriever thrombectomy for acute ischemic stroke in the period between January 2014 and April 2016 at the Department of Neurointerventional Radiology, were analyzed...

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: Various techniques are described to facilitate stable stent implantation in aortic arch stenosis or coarctation. We describe an alternative technique, which due to its unique appearance during stent implantation, we have named "Dog Bone Technique" (DBT). TECHNIQUE: The stent/balloon assembly is placed across the stenosis, the long sheath is retrieved to uncover the distal 20-50% of the stent. The balloon is inflated with the pressure inflator just to expand slightly the stent...

BACKGROUND: One of the mechanisms for periprocedural neurologic events in carotid artery stenting (CAS) is catheter manipulation within the aorta and supraaortic arteries causing plaque embolization. Therefore, the present analysis sought to determine risk factors for embolic particle dimensions and their relationship with adverse clinical events after CAS. METHODS: Between 1999 and 2015 embolic protection devices (EPD) of a total of 944 CAS procedures were evaluated regarding the occurrence and size of captured particles...

Coronary stent dislodgement is a rare and serious complication of percutaneous coronary intervention and is associated with major adverse cardiac events. Successful retrieval of the stent is recommended in this situation because it is important for the prognosis. Recently, a patient was referred to our hospital with a dislodged coronary stent. When attempting to percutaneously extract the dislodged stent, a challenging situation was encountered, as the stent was entrapped and tightly entangled with another fully deployed coronary stent...

OBJECTIVES: We aimed to illustrate one of the mechanisms of rotational atherectomy burr entrapment in a coronary stent where the burr was rolled up in the stent's struts. METHODS: We report a case where the treatment of a mid right coronary artery (RCA) lesion using a rotational atherectomy device was attempted. During the procedure, the burr suddenly got stuck in a freshly implanted stent in the distal RCA. Despite several attempts and maneuvers, we were unable to pull back the burr...

INTRODUCTION: Cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. CASE PRESENTATION: We describe a case where the tumor originated on the mitral valve and extended through the left ventricular outflow tract and aortic valve and into the left main artery obstructing it. Due to the hemodynamic instability of the patient, we proceeded for cardiac catheterization with the intention to aspirate the mass but were forced to do percutaneous intervention to stabilize the patient and bridge him to surgery...

BACKGROUND AND AIMS: Stent retriever-based thrombectomy (SRT) may be beneficial in patients with large hemispheric stroke. Previous studies concluded that favorable outcomes are far less frequent after endovascular therapy in older patients but have not explored outcomes in the era of newer-generation stent retrievers. MATERIALS AND METHODS: Consecutive patients with large hemispheric stroke treated with SRT were included. We compared neurological and functional outcomes between patients younger and older than 80...
