Torstein R Meling
Treatment of blood blister-like aneurysms (BBAs) of the supraclinoidal internal carotid artery (ICA) is challenging and the optimal treatment is yet to be defined. The treatment options for ICA BBAS are microsurgery, endovascular therapy, or a combination of the two. The microsurgical armamentarium consists mainly of direct aneurysm clipping with or without protective EC-IC bypass, clip-wrapping, or trap ligation with ICA sacrifice with or without EC-IC bypass. The endovascular treatment options are mainly endovascular ICA ligation, multiple overlapping stents (≥ 3) with or without coiling, covered stents, or flow diverters...

Carotid stent angioplasty (CAS) has been shown to protect patient from future stroke long-term efficacy similar to carotid endarterectomy (CEA). The risk of minor stroke in the perioperative period is higher than with CEA and not related to cerebral protection during the CAS procedure since a significant portion of the neurologic events occur between 1 and 30 days following stent deployment. This observation suggests mechanisms integral to the stent itself may be pertinent such as plaque embolization thru the stent struts may occur...

Prior clinical trials produced evidence-based treatment recommendations for patients with asymptomatic carotid stenosis that may not be appropriate for clinical decision-making today. High-quality patient outcomes data to allow informed decision making regarding the optimal management of high-grade asymptomatic internal carotid artery stenosis is lacking. The results of the Asymptomatic Carotid Atherosclerosis Study were published in 1995 based on a randomized patient enrollment in the 1990s. Outcomes after endarterectomy, stenting, and medical treatment for these patients have all improved in the subsequent 2 decades...

OBJECTIVE/BACKGROUND: The objective was to assess the mid-term results of pharmacomechanical catheter-directed thrombolysis (PCDT) for symptomatic acute and subacute inferior vena cava (IVC) thrombosis; the risk factors of early thrombosis recurrence and iliocaval patency were also evaluated. METHODS: From January 2010 to December 2015, 54 patients (33 men; mean age 47.1 years) with symptomatic acute and subacute IVC thrombosis were treated with PCDT. Primary technical success (clot lysis ≥ 50% after PCDT), stent-assisted technical success (residual stenosis < 30% after stenting), clinical success (freedom from thrombosis recurrence within 30 days), complications, frequency of post-thrombotic syndrome (PTS; Villalta score ≥ 5), and iliocaval patency were recorded at follow-up evaluation...

INTRODUCTION: Carotid artery stenting (CAS) is a promising alternative to surgery in high-risk patients. However, the impact of stent cell design on outcomes in CAS is a matter of continued debate. AIM: To compare the periprocedural and clinical outcomes of different stent designs for CAS with distal protection devices. MATERIAL AND METHODS: All CAS procedures with both closed- and hybrid-cell stents performed at our institution between February 2010 and December 2015 were analyzed retrospectively...

Selected from the family of self-designed biodegradable amino acid-based poly (ester urea urethane) (AA-PEUU) pseudo-protein biomaterials, arginine-leucine based poly (ester urea urethane)s (Arg-Leu-PEUUs) were used as protective and bio-functional coatings for bio-absorbable magnesium alloy MgZnYNd in cardiovascular stent applications. Comparing with poly (glycolide-co-lactide) (PLGA) coating, the Arg-Leu-PEUU coating had stronger bonding strength with the substrate; in vitro electrochemical and long-term immersion results verified a significantly better corrosion resistance...

Carotid artery stenting (CAS) has recently changed the status in the treatment of the extracranial carotid atheromasic disease. In recent years, evolution in both stents and protection devices as well as in carotid stenting techniques, has resulted in an important reduction in the rate of stroke in patients undergoing CAS procedures. Areas covered: The purpose of this article is reviewing the literature and summarizing the current evidence of the new available materials to underline the importance of the correct choice of the devices during the procedure...

Acute vascular injury occurs in a number of important clinical contexts, including spontaneous disease-related events (e.g. plaque rupture, thrombosis) and therapeutic interventions such as angioplasty, stenting, or bypass surgery. Endothelial cell (EC) disruption exposes the underlying matrix, leading to a rapid deposition of platelets, coagulation proteins, and leukocytes. A thrombo-inflammatory response ensues characterized by leukocyte recruitment, vascular smooth muscle cell (VSMC) activation, and the elaboration of cytokines, reactive oxygen species and growth factors within the vessel wall...

AIMS: The aim of this study was to identify the findings by optical coherence tomography (OCT) after carotid artery stenting (CAS) with two different types of new generation mesh- covered stents. METHODS AND RESULTS: Sixteen consecutive patients undergoing CAS with mesh-covered stents and high-definition OCT image acquisition were enrolled in the study. Cross-sectional OCT images for the presence of strut malapposition (SM) and plaque prolapse (PP) were evaluated under using the proximal or distal embolic protection device (EPD)...

A 77-year-old man underwent duodeno-cephalo-pancreatectomy with Roux-en-Y reconstruction for pancreatic head cancer. After two years developed recurrent cholangitis with obstructive jaundice. In suspicion of obstruction of biliary tree, a percutaneous transhepatic cholangiography (PTC) was attempted. Contrast dye injected troughs the catheter shower an intestinal stenosis about 10 centimeters above the bilio-enteric anastomosis. Following PET-CT scan showed no cancer recurrence.

INTRODUCTION: Coronary chronic total occlusions (CTOs) are commonly encountered during diagnostic angiograms. With recent advances, especially in experienced centers, success rates with CTO percutaneous coronary intervention (PCI) have approached 80% or higher. It is important to note that despite these advancements in techniques, CTOs remain difficult to treat. We present a case of a left circumflex artery (LCX) CTO that was successfully revascularized using a microcatheter balloon pinning technique that allowed additional wire support...

BACKGROUND: Few patients presenting with acute ischemic stroke (AIS) are eligible for alteplase, especially those receiving ongoing anticoagulation. We describe the first reported case of a patient receiving full-dose intravenous (IV) alteplase for AIS after heparin reversal with protamine. CASE: A 73-year-old male presented with AIS. He was treated with IV heparin, tirofiban, loading-dose prasugrel, and aspirin prior to percutaneous coronary intervention (PCI) for placement of a right coronary artery stent...

C Mel Wilcox
In this issue of the Journal, Professor Elmunzer provides an outstanding overview of the variable methods of prevention of post-ERCP pancreatitis (PEP) (1). We all recognize the importance of this topic given its morbidity for our patients. His review succinctly summarizes a wealth of both old and new data underscoring previously identified risk factors for PEP which have stood the test of time. In addition, newer interventions are appraised and placed in an appropriate context. This article is protected by copyright...

BACKGROUND: Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an very important role as alternative treatment modality, especially in patients with critical, symptomatic lesions. This study was single-centre study to evaluate the technical and clinical success of proximal protection devices as the first choice for embolic protection in symptomatic and asymptomatic carotid stenosis in patients with bilateral, advanced lesions of carotid arteries (bilateral stenoses or stenosis and occlusion)...

INTRODUCTION: The lens of the eye is extremely susceptible to radiation and long-term exposure can induce cataract formation. Our objective was to explore the risk of cataract formation for urologists at our institution. METHODS: A retrospective review of a multi-surgeon database of fluoroscopic cases between 10/2013 to 12/2014 was queried. Procedures were performed by different subspecialties and ranged from stent insertion/ureteroscopy to percutaneous nephrolithotomy...
