BACKGROUND: Orbital infarction syndrome (OIS) is a rare entity defined as ischemia of all intraorbital and intra-occular structures including the optic nerve, extraocular muscles and orbital fat. This entity is rare due to rich anastomotic orbital vascularization from both the internal carotid artery and external carotid artery. We report a case of a patient who suffered ENT to the ophthalmic artery and external carotid artery which resulted in orbital infarction syndrome and describe techniques to avoid such complications...

BACKGROUND: Currently, acute ischemic stroke is still a leading cause of mortality and morbidity. Approximately 2 years ago, mechanical thrombectomy was proven beneficial as a revolutionary new therapy for stroke in the MR-CLEAN trial (A Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands). However, the mechanisms by which the thrombectomy device, or stent-retriever, interacts with the thrombus are largely unknown. A better understanding could lead to improved efficacy of mechanical thrombectomy devices...

BACKGROUND: Known complications of endoscopic retrograde cholangiopancreatography (ERCP) include pancreatitis, bleeding, duodenal perforation, and venous air embolism (VAE). The aim of this study was to determine the incidence of VAE during ERCP and be able to differentiate high-risk versus low-risk ERCP procedures. METHODS: This is a prospective cohort study consisting of patients who underwent ERCP and were monitored with a precordial Doppler ultrasound (PDU) for VAE...

BACKGROUND: Stent retriever thrombectomy (SRT) in acute thromboembolic stroke can result in post-thrombectomy subarachnoid hemorrhage (PTSAH). Intraprocedural findings associated with PTSAH are not well defined. OBJECTIVE: To identify angiographic findings and procedural factors during SRT that are associated with PTSAH. MATERIALS AND METHODS: This was a retrospective, observational cohort study of consecutive patients with middle cerebral artery (MCA) acute ischemic stroke treated with SRT...

Carotid artery free-floating thrombus (FFT) is a rare but clinically significant cause of embolic stroke. Treatment has historically been confined to carotid surgery or best medical therapy, with neither option proved to be superior. However, recent advancements in endovascular interventions have heralded a new age of innovative management strategies for vascular disease. We present three distinct cases of stroke secondary to carotid artery FFT, successfully treated with stent retriever endovascular thrombectomy...

BACKGROUND: A new complication, longitudinal stent deformation (LSD), is increasingly reported with recent intracoronary stent designs. We experienced unusual cases of distal LSD caused by entrapment of a Lacrosse® non-slip element (NSE) balloon (Goodman Co., Ltd., Nagoya, Japan), which comes with three flexible nylon elements to prevent slippage. Accordingly, the aim of this study is to report the clinical experience of distal LSD caused by the NSE in our center and to investigate the incidence and mechanisms involved...

BACKGROUND: Recent trials established the efficacy of mechanical stent-retriever thrombectomy for treatment of stroke patients with large vessel occlusion (LVO) in the anterior circulation. However, stent-retriever thrombectomy may not accomplish successful recanalization in all patients. The aim of this study is to report the role of bail-out permanent stenting after failure of mechanical thrombectomy. METHODS: Among 430 patients included in a prospectively maintained database, we analysed 325 cases of anterior circulation LVO...

BACKGROUND AND PURPOSE: Endovascular therapy is the standard of care for the treatment of proximal large vessel occlusion strokes. Its safety and efficacy in the treatment of distal intracranial occlusions has not been well studied. METHODS: The data that support the findings of this study are available from the corresponding author on reasonable request. Retrospective review of a prospectively collected endovascular database (2010-2015, n=949) for all patients with distal intracranial occlusions treated endovascularly...

PURPOSE:  Various stent retrievers differing in stent design and mechanical properties are currently available for the treatment of ischemic stroke. We conducted this in vitro study to compare the efficacy, embolism rate, and safety of commercially available stent retrievers and prototypes. MATERIALS AND METHODS:  Whole blood thrombi were produced in a Chandler loop. The thrombi were inserted into the curved M1 segment of a silicone model of the anterior cerebral circulation...

A neonatal ductal stent deployed in a straight short conical duct on second postnatal day migrated owing to inadequate ductal constriction. It was successfully retrieved using a larger balloon and redeployed in the duct again. Intravenous indomethacin prevented further stent migration. This is the first report of successful transcatheter retrieval and repositioning of a migrated expanded neonatal ductal stent.

Hemorrhagic transformation (HT) is one of the most feared complications of acute recanalization therapies. The aim of this study was to evaluate whether blood-brain barrier permeability (BBBP) imaging can predict HT in the setting of acute recanalization therapy and to determine the sensitivity and specificity of BBBP for the prediction of HT according to the type of reperfusion therapy. We assessed a total of 46 patients who received recanalization therapy (intravenous (IV) recombinant tissue plasminogen activator (tPA), mechanical thrombectomy with a stent retriever or both) for acute ischemic stroke within the internal carotid artery or middle cerebral artery...

INTRODUCTION: Debate continues about the optimal anesthetic management for patients undergoing endovascular treatment (ET) of acute ischemic stroke due to emergent large vessel occlusion. OBJECTIVE: To compare, using current evidence, the clinical outcomes and procedural characteristics among patients undergoing general anesthesia (GA) and local or monitored anesthesia (non-GA). METHODS: We performed a systematic review and meta-analysis of all available studies that involved the use of stent retrievers for ET (stentriever group)...

Hepatic artery thrombosis (HAT) is a major cause of morbidity and mortality after orthotopic liver transplantation, occurring in 5% of cases (Piardi et al, 2016). HAT is the second main cause of graft loss after primary nonfunction, the leading cause of graft failure in the immediate postoperative period (<1 month), and is associated with a mortality rate of up to 60% without intervention (Piardi et al, 2016; Pareja et al., 2010; Crossin et al., 2003). Although retransplantation is the preferred therapy, the limited availability of donor organs can necessitate urgent, alternative treatment...

A 40-year-old woman presented to our stroke center for a left middle cerebral artery embolic occlusion. This was successfully treated with mechanical thrombectomy using a stent retriever and balloon guide catheter aspiration. The patient was discharged home in good condition on clopidogrel but returned 2 months later with a contralateral right middle cerebral artery embolic occlusion. This was also successfully treated, this time with a stent retriever and local aspiration (Sol-Arc technique). She was once again discharged in good condition but with warfarin and an implanted loop recorder...

Thromboembolism is the most frequent complication in endovascular treatment of intracranial aneurysms, causing disability and death. As stent retrievers have achieved high rates of arterial recanalization in the management of ischemic stroke, these devices were tested as rescue therapy of thromboembolism during aneurysm embolization. We retrospectively analyzed 10 consecutive patients with transprocedural arterial occlusion, treated with mechanical thrombectomy at a single center. Good angiographic recanalization was achieved in eight cases, mTICI 3, 2b and 2a in five, three and two patients, respectively, without additional complications or any deaths...

PURPOSE: To evaluate the efficacy and safety of thrombectomy using myocardial biopsy forceps for the treatment of acute limb ischemia (ALI). MATERIALS AND METHODS: A retrospective review of 11 ALI patients (12 affected limbs, 18 affected vessels) who underwent thrombectomy using biopsy forceps between November 2011 and April 2016 was performed. Of the 12 affected limbs, 2 limbs had stent thrombosis, 1 limb had thrombotic occlusion at a de novo stenosis site, and 9 limbs had embolic ALI...
