Background: Flow diversion with the Pipeline embolization device (PED) is an effective neuro-endovascular method and increasingly accepted for the treatment of cerebral aneurysms. Acute in situ thrombosis is a known complication of PED procedures. There is limited experience in the flow diversion literature on the use of abciximab (ReoPro) for the management of acute thrombus formation in PED cases. Methods: Data were collected retrospectively on patients who received intra-arterial (IA) ReoPro with or without subsequent intravenous (IV) infusion during PED flow diversion treatment of intracranial aneurysms...

Kawasaki disease (KD), which is the leading cause of pediatric heart disease, is characterized by coronary vasculitis and subsequent aneurysm formation. Although intravenous immunoglobulin therapy is effective for reducing aneurysm formation, a certain number of patients are resistant to this therapy. Because interleukin-10 (IL-10) was identified as a negative regulator of cardiac inflammation in a murine model of KD induced by Candida albicans water-soluble fraction (CAWS), we investigated the effect of IL-10 supplementation in CAWS-induced vasculitis...

Here we present a 46-yr-old man with recurrent syncopal episodes thought to be of cardiac origin. He was eventually found to harbor a giant, partially thrombosed, saccular aneurysm arising from the A1/A2 segment of the right anterior cerebral artery with foramen of Monro obstruction and a trapped left-sided ventricular system. An azygous left A2 artery segment supplied both callosomarginal arteries. We performed an in situ side-to-side anastomosis between the distal left azygous anterior cerebral artery and the right pericallosal artery, which was previously supplied by the right A1...

BACKGROUND: Deep hypothermic circulatory arrest (DHCA) is often avoided in patients with concomitant ascending aortic pathology when treating other cardiac disease to avoid increased risk of morbidity and mortality. We hypothesized that the use of DHCA with retrograde cerebral perfusion (RCP) does not add incremental risk to ascending aortic replacement alone in the setting of concomitant cardiac surgery. METHODS: 408 ascending aortic ± hemiarch replacements and aortic (root)/mitral/tricuspid valve(s), CABG, or MAZE procedures were performed for concomitant cardiac disease...

Thrombospondin 4 (TSP-4) expression is induced in the heart and vasculature under pathological conditions, including myocardial infarction, myocardial pressure overload, and hypertension. TSP-4 is linked to remodelling processes, where it may affect extracellular matrix protein organization. In previous work, we studied the role of TSP-4 in small arteries during hypertension using Ang II-treated Thrombospondin 4 knockout (Thbs4-/- ) mice. We reported increased heart weight, as well as the occurrence of aortic aneurysms in the Ang II-treated Thbs4-/- animals...

Aortic dissection is characterized by a tear in the aortic wall resulting in blood from the aortic lumen penetrating into the media, which causes dissection. When aortic dissection does not cause rupture, it provokes localized dilation of the aorta or aneurism, also called dissecting aortic aneurism (DAA). This case report describes a DAA in a cat associated with systemic arterial hypertension (SAHT). A 10-year-old male Domestic shorthair cat was presented for cardiac evaluation. Anamnestic clinical complaints were a syncope associated with paraparesis and weak femoral pules...

INTRODUCTION: Surgical approach of multisegmental pathology of the thoracic aorta, namely aortic arch / descending aorta is challenging. The Frozen Elephant Trunk (FET) has good results, with acceptable risk. However, in the subgroup of patients (pts) older than 75 years and with important comorbidities, the surgical risk is very high. OBJECTIVES: Review short-term results of this original, simplified and potentially hybrid technique developed in our Department for this subgroup of patients...

INTRODUCTION: Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. The optimal treatment in this situation is still a matter of debate. The authors describe a case of late presentation of subclavian artery pseudoaneurysm after transjugular hepatic biopsy and discuss the several options for treatment...

This case describes an unusual presentation of prosthetic valve endocarditis: an acute coronary syndrome. A 67-year-old gentleman presented with cardiac sounding chest pain on a background of a short history of night sweats, weight loss and general malaise. Four months previously he had undergone bio-prosthetic aortic valve replacement for severe aortic stenosis and single vessel bypass grafting of the obtuse marginal. Whilst having chest pain his ECG showed infero-lateral ST depression. Early coronary angiography revealed a new right coronary artery lesion that was not present prior to his cardiac surgery...

Aims: Using non-invasive 3D ultrasound, peak wall stress (PWS) and aortic stiffness can be evaluated, which may provide additional criteria in abdominal aortic aneurysm (AAA) risk assessment. In this study, these measures were determined in both young and age-matched individuals, and AAA patients while its relation to age, maximum diameter, and growth was assessed statistically. Methods and results: Time-resolved 3D-US data were acquired for 30 volunteers and 65 AAA patients...

Early intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease (KD) to reduce the incidence of coronary aneurysms. Patients with atypical presentation or who live in a rural area are less likely to receive treatment in the early stage of presentation and are more likely to develop severe complications. There is little consensus on how to treat coronary aneurysms effectively in the acute or subacute stage especially when giant aneurysms develop that compromise cardiac function. This case study is of a 19-month-old girl who initially was not treated as KD and developed multivessel giant coronary artery aneurysms (CAAs) (>8 mm), acute myocardial infarction, and complete heart block despite late intravenous IVIG administration...

OBJECTIVE: Percutaneous endovascular aneurysm repair (EVAR) can be performed with general anesthesia (GA) or local anesthesia (LA). Our goal was to assess perioperative outcomes comparing anesthesia type in percutaneous EVAR. METHODS: The Vascular Quality Initiative database was queried for all exclusively percutaneous EVAR procedures. Univariable analysis was used to compare which patients were offered LA. Multivariable analysis was used to determine the independent effect of anesthesia type...

PURPOSE OF REVIEW: The effects of statin loading before, during or after vascular interventions on cardiovascular and renal outcomes are discussed. Furthermore, the selection of optimal statin type and dose, according to current evidence or guidelines, is considered. The importance of treating statin intolerance and avoiding statin discontinuation is also discussed. RECENT FINDINGS: Statin loading has been shown to beneficially affect cardiovascular outcomes, total mortality and/or contrast-induced acute kidney injury, in patients undergoing vascular procedures such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), carotid endarterectomy (CEA), carotid artery stenting, endovascular aneurysm repair, open abdominal aortic aneurysms (AAA) repair and lower extremities vascular interventions...

Marc-Alexander Ohlow
Congenital left ventricular aneurysm or diverticulum are rare cardiac malformations described in 809 cases since the first description in 1816, being associated with other cardiac, vascular or thoraco-abdominal abnormalities in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. In an experimental study, targeted knockdown of cardiac troponin T in the chick was performed at day 3, after the heart tube has formed. Morpholino treatment of gene TNNT2 at this stage led to the development of left ventricular diverticula (LVD) in the primitive left ventricular wall...

OBJECTIVE: This study investigated the outcomes of a current series of patients treated with fenestrated and branched endovascular aneurysm repair (F-BEVAR) or open surgical repair (OSR) for pararenal abdominal aortic aneurysms (pr-AAAs), including juxtarenal, suprarenal, and type IV thoracoabdominal aneurysms. This study compares the outcomes of these procedures from two high-volume centers without the bias induced by a learning curve. METHODS: All patients with pr-AAAs undergoing repair at two centers between January 2010 and June 2016 were included in a prospective database...

BACKGROUND: Coronary fistulae are occasionally detected using echocardiography or coronary angiography. We report a patient with cardiac tamponade because of a ruptured aneurysm of a coronary artery fistula. CASE PRESENTATION: A 60-year-old man was referred to our hospital with sudden onset of chest pain and unconsciousness. He was initially diagnosed with cardiac tamponade for type A acute aortic dissection, and an emergency operation was performed. A large amount of bleeding was seen in the pericardium, but aortic dissection around the arch was not observed...
