Eagle syndrome is defined by an elongated styloid process or a calcified stylohyoid ligament that impinges on surrounding structures and causes a variety of symptoms. Classically, Eagle syndrome presents as neck, throat, or ear pain. The vascular variant, stylocarotid syndrome, can present as headache, transient ischemic attack, or stroke. Carotid artery dissection is a rare complication of stylocarotid syndrome. We report a case of stylocarotid syndrome in a 60-year-old man who presented with a right internal carotid artery (ICA) dissection and focal neurological deficits...

Interventional radiology (IR) has become an integral part in the management of traumatic injuries. There is an ever-increasing role of IR in traumatic injuries of solid abdominal organs, pelvic and peripheral arteries to control active bleeding by therapeutic embolization or vascular reconstruction using stent grafts. Traditionally, these endovascular treatments have been offered to hemodynamically stable patients. However, in recent times endovascular approach has become preferable to surgery even in hemodynamically unstable patients with injury of surgically difficult-to-access sites...

EDITORIAL
Francesco Saia
Up to 15-23% of the patients with percutaneous coronary intervention (PCI) and drug-eluting stent (DES) implantation need a surgical procedure <12 months from PCI. Perioperative risk stratification in these patients is challenging and should take into account many individual clinical and anatomic variables, along with the intrinsic surgical risk for ischemic and bleeding events. The presence of DES has always been considered as a harbinger of doom. In fact, DES are associated with delayed vascular healing and require longer dual antiplatelet treatment...

OBJECTIVES: Using intravascular ultrasound (IVUS), the authors compared outcomes by observed wire position (intraplaque vs. subintimal) achieved during successful chronic total occlusion (CTO) lesion treatment. BACKGROUND: Recent successes in CTO percutaneous coronary intervention (PCI) have used both intraluminal and subintimal wire tracking to improve procedural success. IVUS may be used to determine the course of wire tracking after crossing a CTO. METHODS: From March 2014 to March 2016, data were collected into a single-center database from 219 patients undergoing CTO PCI with concomitant IVUS imaging...

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Dual origin of a circumflex from both sinuses is extremely rare among them. We report a case of a patient who underwent primary percutaneous coronary intervention for acute inferior wall myocardial infarction where left coronary injection demonstrated normal obtuse marginal and right coronary injection demonstrated normal right coronary artery (RCA). On further probing, an anomalous left circumflex (LCx) artery was seen arising from RCA ostium which was subsequently cannulated and revascularized by deployment of 2...

Ureteral injuries due to gunshots are tend to be misdiagnosed because of concomitant vascular and intraabdominal organ wounds. Our case is a 23-year-old man who was admitted to the hospital with multiple abdominal gunshot wounds. Laboratory findings showed worsening anemia, and the computed tomography (CT) scan showed multiple lead bullets inside the abdomen and retroperitoneum. Patient was then taken to the operation room for laparatomy. There were many intestinal injuries and also a stable retroperitoneal hematoma...

BACKGROUND Development of a true coronary aneurysm after percutaneous coronary intervention is a rare event, and a coronary aneurysm resulting in acute myocardial infarction is even rarer. Coronary aneurysm formation after bioresorbable vascular scaffold (BVS) implantation, eventually leading to thrombosis, embolization, and myocardial infarction, has never been reported before in the literature. CASE REPORT A 62-year-old man received an elective BVS for a proximal left anterior descending lesion. Two months later, he suffered from a non-ST-segment myocardial infarction...

PURPOSE: Most recent guidelines recommend the use of stent retriever devices in endovascular treatment of acute ischemic stroke with large vessel occlusion (LVO). Recently published data reported convincing results with thromboaspiration devices such as the Penumbra System (Penumbra, Alameda, CA, USA) combined with supple reperfusion catheters by using the ADAPT (A Direct Aspiration First-Pass Thrombectomy) technique. The aim of this study was to report our initial experience with the 3MAX (3...

For the last five years, invasive cardiology in Poland has developed extensively. Currently, 98% of the 161 Polish cathlabs operate in 24/7 mode, 37 of them supported by cardiac surgery departments on-site. A certification curriculum for interventional cardiology operators is supported by dedicated workshops and scientific meetings during national conferences. The rise in the number of coronary angiographies and PCIs was paralleled by an increased use of drug-eluting stents, bioresorbable vascular scaffolds and physiologic assessment of coronary arteries...

The aim of this report is to analyse trends in Italian cathlab activity between 2010 and 2015. Data were obtained from the national database of the Italian Society of Interventional Cardiology (GISE), which includes 97% of Italian cardiac catheterisation laboratories. The number of percutaneous coronary interventions (PCI) has remained relatively stable in the past five years. We have observed a significant increase in the number of primary PCI (pPCI) from 471.5 to 557.5 per million inhabitants with a consequent reduction of rescue primary PCI/fibrinolysis...

Anticancer drugs are commonly used as inhibitors of vascular smooth muscle cell (VSMC) proliferation in clinical treatments. This study aims to investigate how elemene affects the proliferation of VSMCs, the restenosis, and the reendothelialization after implanting the elemene-coated stents. VSMCs derived from rat aorta were used to test the cell proliferation, cell cycle, migration, apoptosis, cytoskeletal protein F-actin, intracellular Ca(2+), IncRNA chip and gene expression of PCNA, P53, and Cx43 when cultured with elemene...

REVIEW
Richard R Heuser
Even though cardiovascular disease (CVD) is still the leading cause of death in the United States, stroke is the second leading of global cause of death behind CVD . In the 21st Century, less than 40% of overall stroke patients are discharged to home and almost 25% of Medicare beneficiaries do not survive 90days. In spite of the fact that tissue plasminogen activator (TPA) has been approved for stroke care for 20years, only .75% of annual strokes are actually treated with intravenous (IV) TPA. Similar to how interventional cardiologists evolved from IV to catheter mechanical treatment for acute myocardial infarctions (AMI) over 30years ago, over the last few years, neurointerventionists now perform endovascular stroke therapy in many of these patients using stent retrievers...

MicroRNAs are key regulators of vascular smooth muscle cells (VSMCs) phenotypic switch, one of the main events responsible for bare metal stent restenosis (ISR) after percutaneous coronary intervention (PCI). miR-125a-5p is an important modulator of differentiation, proliferation and migration in different cell types; however, its role in VSMCs is still unknown. The aim of this study was to evaluate the role of miR-125a-5p in VSMCs phenotypic switch. Our results suggest that miR-125a-5p is highly expressed in VSMCs, but it is down-regulated after vascular injury in vivo...

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

PURPOSE: To present an easy and quick technique for embolization of the inferior mesenteric artery (IMA) during endovascular aneurysm repair (EVAR). TECHNIQUE: We performed IMA embolization using a conventional EVAR device alone with the femoral artery approach during EVAR, which has not been reported previously. First, a 16F or 18F DrySeal Sheath is inserted from the femoral artery into the site around the IMA. Second, cannulation is performed in the IMA with an angiography catheter having a 0...

BACKGROUND: Cell-based therapy that can rejuvenate the endothelium with stimulated adipose-derived mesenchymal stem cells (AMSCs) is a promising therapeutic strategy for the re-endothelialization of denuded arteries at the stenting site. Previously, we have shown that silencing of MMP-2 and MMP-14 inhibits vascular endothelial growth factor receptor type 2 (VEGFR2) cleavage, and induces differentiation of AMSCs toward the endothelial cell (EC) lineage. In this study, we examined the underlying signaling pathways that regulate differentiation of AMSCs to ECs in vitro through VEGFR2...

Binary Zn-Cu alloy system is developed as potential biodegradable materials for cardiovascular implant application. The microstructure, tensile properties, in vitro corrosion behavior, cytotoxicity and antibacterial property of as-extruded Zn-xCu (x=1, 2, 3, and 4wt%) alloys are investigated systematically. It shows that as Cu content increases more CuZn5 phase precipitates. After extrusion, the CuZn5 phases are broken and the grains of Zn-xCu alloys are refined. Tensile test shows that Cu addition could significantly improve the mechanical properties of Zn-xCu alloys...
