BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...

Stroke prevention is the main priority in the management cascade of atrial fibrillation. Most patients require long-term oral anticoagulation (OAC) and may require percutaneous coronary intervention. Prevention of recurrent cardiac ischemia and stent thrombosis necessitate dual antiplatelet therapy (DAPT) for up to 12 months. Triple antithrombotic therapy with OAC plus DAPT of shortest feasible duration is warranted, followed by dual antithrombotic therapy of OAC and antiplatelet agent, and OAC alone after 12 months...

The management of disconnected pancreatic duct syndrome is complex and is increasingly approached using emerging endoscopic techniques. Here, we present a case of recurrent pancreatitis in an elderly woman complicated by pseudocyst formation and complete pancreatic duct disruption. Her condition was treated with a novel combination of transpapillary stenting and cystduodenostomy in which a pancreatic duct stent was placed into an opening in the pseudocyst wall via lumen-apposing metal stent. This allowed for effective drainage into the gastrointestinal tract and resolution of duct disruption...

Surgical voice rehabilitation is an essential dimension of treatment following total laryngectomy. The gold standard is tracheo-oesophageal puncture and speaking valve placement. Whilst offering excellent phonation in many patients, there is a well-documented risk of valve associated fistula formation, the incidence of which varies from 1 to 21% (1) . Risk factors for delayed valve associated tracheo-oesophageal fistula include post chemo-radiotherapy (salvage laryngectomy), oesophageal stricture, persistent fungal infection and poor patient compliance in managing their speaking valve(2) ...

Carotid artery stenting performed with distal embolic protection devices continues to show elevated rates of periprocedural stroke, in particular with high-risk groups. This article discusses the factors associated with protection devices that may contribute to this complication, performs a literature review to assess outcomes of carotid stenting with proximal occlusion devices, and assesses the role of proximal occlusion devices in the management of patients with carotid artery stenosis.

BACKGROUND: Bare metal stents may cause complications like fibrous encapsulation, granulation and tracheal stenosis. We investigated the behavior of three commercially available stents in vivo (rabbits) and in vitro (co-culture of those stents with epithelial and fibroblast cell lines). Also, we investigated whether development of tracheal stenosis could be predicted by any biological marker. METHODS: The tracheae of 30 rabbits were implanted with either nitinol stents, with or without paclitaxel elution, or a cobalt-based stent...

Stroke, which is defined as a neurologic deficit caused by sudden impaired blood supply, has been considered as a common cause of death and disability for decades. The World Health Organization has declared that almost every 5 seconds a new stroke occurs, placing immense socioeconomic burdens. However, the effective and available treatment strategies are still limited. Additionally, the most effective therapy, such as thrombolysis and stenting for ischemic stroke, generally requires a narrow therapeutic time window after the event...

BACKGROUND: Little is known about the micro-debris captured in filter-type distal embolic protection devices (EPD) used for carotid stenting (CAS). This study aimed to determine the histological and immunohistochemical characteristics of such debris by using a new liquid-based cytology (LBC) technique. METHODS: Fifteen patients who underwent CAS using a filter-type distal EPD (FilterWire EZ; Boston Scientific, Marlborough, MA, USA) were included in the study. After gross inspection of each recovered filter device, micro-debris were collected using a new LBC technique (SurePath; TriPath Imaging, Inc...

Renal artery stenosis (RAS) is the most common vascular complication following renal transplantation. Percutaneous endovascular transluminal angioplasty with stenting is the treatment of choice for clinically significant RAS. We present a case describing a novel combined trans-renal parenchyma and trans-femoral approach to repairing a disrupted transplant renal artery stent. Our patient's allograft RAS was initially managed by standard percutaneous approach, but during follow-up the stent became disrupted and crushed causing partial occlusion of the renal artery...

INTRODUCTION: Carotid artery stenting (CAS) is typically performed using embolic protection devices (EPDs) as a means to reduce the risk of procedure-related stroke. In this study, we compared procedural morbidity and mortality associated with distal (D-EPD) vs. proximal (P-EPD) protection. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were queried from January 1998 through May 2015. Only studies comparing (D-EPD) and (P-EPD) were included...

Ureteral stent (UrSt) placement has been shown to be a significant independent risk factor for BK viruria, viremia and BK virus nephropathy. We assessed if this observation could be validated at our high volume kidney transplant center that has had a strong historical focus on BK virus nephropathy detection. We performed a retrospective case-control study of adults receiving a kidney-only transplant and followed for one year between 2004 and 2011 with uniform immunosuppression and use of blood BK virus PCR screening protocol...

Mirizzi syndrome is the compressive blockage of the cystic or choledochal duct caused by a biliary stone occupying the cystic canal or Hartmann's pouch. This occurrence is rare and, in English literature, three cases defined in children have been observed. In order to draw attention to this rare occurrence, we preferred a 14-year-old male patient with Mirizzi syndrome. In this case, ERCP was performed preoperatively and the diagnosis was carried out with the help of clear visualisation and identification of the tissue structures as well as the stent placed in bile duct; so we protected the patient from the possible iatrogenic injury occurring during surgery...

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...

Endovascular aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysm (AAA). However, persistent AAA sac endoleak following EVAR can result in sac diameter increase requiring re-intervention in up to one-third of cases and even result in aneurysm rupture. In this case review, we summarize and detail endovascular re-interventions for each type of endoleak. We also detail specific options including stent-graft relining for indeterminate, Type III, and Type IV endoleaks and perigraft arterial sac embolization to induce thrombosis and resolve acute Type I, II, or III endoleaks...
