Chimney-and-periscope technique for thoraco-abdominal aneurysm repair is a valuable treatment option in selected patients. Acute renal artery occlusion is a serious complication after this technique. We report a case of acute right renal artery occlusion, consequent to a previous chimney-and-periscope technique that was treated urgently by mechanical aspiration thrombectomy.

OBJECTIVE: During thrombectomy, thromboembolic migration in previously unaffected territory may occur and is not systematically notified. We report our data on the incidence, predictors, and clinical outcome of anterior cerebral artery emboli (ACAE). METHODS: From a prospectively collected thrombectomy database of consecutive patients with anterior circulation stroke between January 2012 and December 2016, 690 angiographic images were analyzed to assess ACAE. The primary outcome was a favorable outcome, defined as a 3 month modified Rankin Scale score of 0-2 or equal to the pre-stroke score...

There is little guidance in the literature on which thrombectomy technique is preferred in patients with acute ischemic stroke and concomitant aneurysms. Here, we present the case of a 58-year-old female with an acute ischemic stroke requiring emergent thrombectomy that was complicated by the presence of multiple, nonruptured intracranial aneurysms. Imaging confirmed an occlusion of the right middle cerebral artery and multiple nonruptured intracranial aneurysms. The patient was administered intravenous recombinant tissue plasminogen activator and the thrombus was aspirated via a direct aspiration first pass technique (ADAPT)...

A saphenous vein graft chronic total occlusion intervention is uncommonly performed, partly due to the high risk of distal embolization. We described a strategy in which after successful wiring of a saphenous vein graft chronic total occlusion, balloon dilatation was performed to create a blind sac within the lesion, followed by aspiration thrombectomy to remove all the dislodged debris. Thereafter, balloon dilatation and stenting were safely performed in the distal occluded segment, to achieve complete recanalization...

Background: Endovascular treatment options for internal carotid artery (ICA) dissection with tandem intracranial occlusion are evolving. We report 2 cases of stent reconstruction of carotid loop dissections. Methods: Two patients with symptomatic ICA dissections of true 360° tonsillar loops and tandem intracranial occlusions were treated with manual aspiration thrombectomy (MAT) and telescoping Zilver self-expanding peripheral stents. Patient demographics, clinical presentations, endovascular techniques, and clinical outcomes were reviewed...

Background: Application of direct aspiration catheters has revolutionized acute stroke care and has led to significant improvement in clinical outcome with a good safety profile. Catheter fracture and retention is a rare but potentially devastating complication. Case Description: Here we present two cases of acute stroke complicated by aspiration catheter fracture and retention. Successful catheter retrieval and revascularization was achieved in both cases. The stenosis or tortuosity of vascular anatomy appears to be the probable contributor to catheter breakage by anchoring the catheter with resultant fracture at the constraint point from catheter withdrawal tensile stress...

Cerebral venous sinus thrombosis is sometimes fatal. We describe a case of sinus thrombosis in a 43-year-old woman presenting with generalized seizure, delirium, and a 2 week history of headache and nausea. The patient underwent mechanical thrombectomy using a novel combined approach, in which a Shouryu HR balloon catheter (Kaneka) was anchored in the right transverse sinus (TS), sigmoid sinus (SS), and superior sagittal sinus (SSS), while a Penumbra 5 MAX ACE (Penumbra) catheter was moved back and forth between the right TS, SS, and SSS...

Stent-retriever thrombectomy for atherosclerotic acute occlusion of cerebral arteries is difficult. We experienced three patients with middle cerebral artery atherosclerotic occlusion who achieved successful recanalization with the combined use of aspiration thrombectomy devices and cerebral angioplasty balloons. The combination is feasible in terms of smooth delivery of the balloon catheter.

Catheter-related arterial thrombosis (CAT) is increasingly recognized in children. Available data are scarce and based on expert opinions. This systematic review aimed to identify knowledge on paediatric CAT. Among 3,484 publications, 22 met inclusion criteria. Fourteen reported on CAT due to umbilical arterial catheter (UAC), two to extremity indwelling catheter (EIC), one to both and five to cardiac catheter (CC). The overall cumulative incidence of CAT was 21% (95% confidence interval [CI], 13-31) with a relative incidence of 20% (95% CI, 10-33) for UAC and 11% (95% CI, 3-21) for CC-related CAT...

Aims: Preliminary studies suggest that direct stenting (DS) during percutaneous coronary intervention (PCI) may reduce microvascular obstruction and improve clinical outcome. Thrombus aspiration may facilitate DS. We assessed the impact of DS on clinical outcome and myocardial reperfusion and its interaction with thrombus aspiration among ST-segment elevation myocardial infarction (STEMI) patients undergoing PCI. Methods and results: Patient-level data from the three largest randomized trials on routine manual thrombus aspiration vs...

Endovascular reconstruction for carotid artery dissection (CAD) involving a highly tortuous segment of the cervical internal carotid artery (ICA) is challenging because the tortuous ICA may preclude navigation of large-profile carotid stents. Successful recanalization using low-profile neurostents has been reported in small case series only. We herein describe two patients with CAD of a tortuous segment who were successfully treated with large-profile carotid stents after straightening the ICA with a stiff peripheral microguidewire...

INTRODUCTION: Completed randomized trials on endovascular thrombectomy (ET) did not independently assess the efficacy of ET in the elderly (≥80 years old) who were often excluded or under-represented in trials. There were also inconsistent criteria for patient selection in this population across the different trials. This work evaluates outcomes after ET for acute ischemic stroke (AIS) in the elderly at a high volume stroke center. METHODS: We reviewed all cases of AIS that underwent a direct aspiration first pass technique (ADAPT) thrombectomy for large vessel occlusions between March 2013 and October 2017 while comparing outcomes in the elderly with younger counterparts...

The dextro-transposition of great arteries (d-TGA) is a rare, congenital, cyanotic heart disease and there is a paucity of data regarding long-term cardiovascular outcomes. We present a rare case of non-ST-elevation myocardial infarction (NSTEMI) in a patient with surgically repaired d-TGA. A 43-year-old male who had previously undergone a Mustard atrial switch palliative procedure presented with chest pain and diaphoresis and was diagnosed with NSTEMI. A coronary angiogram revealed a small, underdeveloped, left anterior descending and a large, left circumflex coronary artery with an acute embolic lesion...

Background: Various techniques are used to enhance the results of mechanical thrombectomy with stent-retrievers, including proximal arrest with balloon guide catheter (BGC), conventional large bore proximal catheter (CGC), or in combination with local aspiration through a large-bore catheter positioned at the clot interface (Aspiration-Retriever Technique for Stroke [ARTS]). We evaluated the impact of ARTS in the North American Solitaire Acute Stroke (NASA) registry. Summary: Data on the use of the aspiration technique were available for 285 anterior circulation patients, of which 29 underwent ARTS technique, 131 CGC, and 125 BGC...

BACKGROUND AND PURPOSE: Although successful reperfusion is usually defined as a modified Thrombolysis in Cerebral Infarction (mTICI) 2B or 3 at the end of the procedure, studies have shown that mTICI 2B patients had poorer functional outcomes than TICI 3 patients. An mTICI 2C category has been recently introduced for patients with near-complete perfusion except for slow flow in a few distal cortical vessels or presence of small distal cortical emboli after mechanical thrombectomy. The purpose of this study was to evaluate the difference in functional outcome between patients achieving successful reperfusion (ie, mTICI 2B, mTICI 2C, and TICI 3 scores)...

BACKGROUND AND PURPOSE: Despite the recent technical evolution of the endovascular treatment of acute ischemic stroke, late and incomplete recanalization can be achieved after several maneuvers but with a potentially higher risk of futile reperfusion and complications, such as clot fragmentation. The aim of this article is to investigate the impact of the angiographic phenotype of M1-middle cerebral artery occlusions, classified as regular and irregular in aspect, on the results of treatment by stent retrievers (SRs) or contact aspiration (CA)...
