Transarterial chemoembolization (TACE) is an effective palliative intervention that is widely accepted for the management of hepatocellular carcinoma (HCC). Post-TACE pulmonary complications resulting in acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) are rare events. Pulmonary complications after TACE are thought to be related to chemical injury subsequent to the migration of the infused ethiodized oil or chemotherapeutic agent to the lung vasculature, facilitated by arteriovenous (AV) shunts within the hyper-vascular HCC...

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery...

BACKGROUND AND OBJECTIVE: Dyspnoea in pulmonary embolism (PE) remains poorly characterized. Little is known about how to measure intensity or about the underlying mechanisms that may be related to ventilatory abnormalities, alveolar dead space ventilation or modulating factors such as psychological modulate. We hypothesized that dyspnoea would mainly be associated with pulmonary vascular obstruction and its pathophysiological consequences, while the sensory-affective domain of dyspnoea would be influenced by other factors...

Subclavian vein puncture is a relatively fast and safe technique to access the right heart for placement of pacemaker leads. Hemothorax related to injury of the pulmonary artery (PA) is a rare complication of subclavian vein access but can be life-threatening. We report a case of hemothorax occurring after subclavian vein puncture for pacemaker implantation. No cases of transcatheter arterial embolization for PA injury secondary to pacemaker implantation have been reported. Understanding of this rare complication after pacemaker implantation along with its specific clinical presentation may lead to early diagnosis and intervention...

BACKGROUND: Whether the localization of non-massive pulmonary embolism (PE) is associated with the short and long-term prognosis of patients remains unknown. Our aim is to characterize associations of non-massive PE localization with risks of recurrent venous thromboembolism (VTE), major bleeding and mortality during and after anticoagulation. METHODS: Among participants of the RIETE registry with an incident symptomatic non-massive PE diagnosed by computerized tomography (CT), we compared risks of recurrent VTE, major bleeding and mortality during and after anticoagulation period between central PE (main pulmonary artery) and non-central PE (more peripheral arteries), using Cox proportional hazard adjusted models...

OBJECTIVE: To test the hypothesis that more cardiovascular emergencies occur at low rather than at high temperatures under moderate climatic conditions. METHODS: This was a prospective observational study performed in a prehospital setting. Data from the Emergency Medical Service in Hamburg (Germany) and from the local weather station were evaluated over a 5-year period. Temperature data were matched with the associated rescue mission data. Lowess-Regression analysis was performed to assess the relationship between the temperature and the frequency of individual cardiovascular emergencies...

Cardiac catheterization is commonly performed in patients being supported by extracorporeal membrane oxygenation (ECMO). We aimed to evaluate the safety, benefit, and outcomes of catheterization in pediatric patients supported by ECMO. Retrospective review of cardiac catheterizations performed in patients ≤18 years of age while on ECMO at a large tertiary care center between January 2000 and May 2015. A total of 55 catheterizations were performed on 51 patients during 53 unique ECMO courses. Indications for ECMO include ventricular dysfunction (22), cardiac arrest (20), inability to wean from cardiopulmonary bypass (7), and persistent cyanosis (4)...

AIMS: To present our experience with the Amplatzer Duct Occluder Type II Additional Sizes (ADOIIAS) for the closure of different types of the patent ductus arteriosus (PDA) in patients of various age groups. METHODS AND RESULTS: A group of 103 patients were analyzed, in whom the PDA (diameter below 3,5 mm) was closed using the ADOIIAS. The median age of treated patients was 3,0 years (from 0,1 until 24 years), and 55 patients (53,4%) were older than 3 years. Ductal anatomy defined by angiography showed type A in 42 patients (40,8%), type C in 6 patients (5,8%), type D in 21 patients (20,5%), and type E in 34 patients (33,0%)...

Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery...

OBJECTIVE: We report our recent experience with the new Occlutech(®) PDA Occluder, which seems suitable especially for closure of large patent ductus arteriosus (PDA) sizes with elevated pulmonary artery pressure (PAH). BACKGROUND: Although considered a standard procedure in pediatric cath labs, closure of very large PDA (PDA/Aorta ratio > 0.5) and PAH remains a challenge. METHODS/RESULTS: The Occlutech(®) PDA occluder was used in eight children and adolescents (age 4-16, median 10...

PURPOSE: Occlusion time (OT) is an important factor in the treatment of pulmonary arteriovenous malformations (PAVMs) since it can lead to serious complications. The purpose of our study is to calculate the OT of Amplatzer vascular plug (AVP, St Jude Medical), and correlate it to the type of the device used (AVP or AVP 2) and the percent of device oversizing. Technical success rates and complications were also recorded. METHODS: We retrospectively studied a total of 19 patients with 47 PAVMs who received percutaneous transcatheter embolization therapy using either AVP or AVP 2...

Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and/or pulmonary embolism (PE). Many surgeons and clinicians believe that VTE after coronary artery bypass grafting (CABG) has little clinical significance because it is seldom diagnosed. This study aimed to identify VTE after CABG, independent of clinical suspicion. In this prospective, observational, single-center study, 100 patients underwent computed tomographic pulmonary angiography (multidetector-64) and lower extremity venous compressive ultrasound after elective CABG...

BACKGROUND: Cemented total hip arthroplasty (THA) is a safe and common procedure. In rare cases life threatening bone cement implantation syndrome (BCIS) may occur, which is commonly caused by pulmonary embolism (PE). CASE PRESENTATION: We describe the rare case of a 70-year old patient who underwent an elective total hip replacement. Before surgery he was diagnosed with underlying systemic indolent mastocytosis, a rare pathological disorder that may result in anaphylaxis after massive systemic mast cell activation...
