We here report the case of a 52-year old hypertensive, obese woman (BMI 32,46 kg/m(2)) with a past history of smoking and without evidence-based risk factors of venous thromboembolism, hospitalized for left chest pain radiating to the dorsolumbar region associated with dyspnoea. Clinical examination on hopitalization showed left blood pressure 100/60 mmHg, tachycardia 100/min, oxygen desaturation index at 88% with the patient breathing ambient air, normal cardiopulmonary auscultation, peripheral pulses palpable and no symptoms of phlebitis of the lower limbs...

Introduction: The inadvertent or purposeful introduction of foreign bodies or substances can lead to cerebral infarction if they embolize to the brain. Individual reports of these events are uncommon but may increase with the increased occurrences of their risk factors, for example, intra-arterial procedures. Method: We searched EMBASE and MEDLINE for articles on embolic stroke of nontissue origin. 1889 articles were identified and screened and 216 articles were ultimately reviewed in full text and included in qualitative analysis...

Systemic air emboli occur as a rare complication of percutaneous needle biopsy of the lung and video-assisted thoracoscopic surgery (VATS) marking. Here we present four cases of systemic air emboli from single institution and the imaging findings and embolism' kinetics using contrast-enhanced media during VATS color marking with indocyanine green. We suggest that early detection using routine whole-lung CT is required for asymptomatic patients with abnormal air. If abnormal air is found, we should keep the patient to the appropriate posture in order to prevent moving the air until it dissipates...

PURPOSE: To compare image quality and radiation exposure between a new angiographic imaging system and the preceding generation system during uterine artery embolization (UAE). MATERIALS AND METHODS: In this retrospective, IRB-approved two-arm study, 54 patients with symptomatic uterine fibroids were treated with UAE on two different angiographic imaging systems. The new system includes optimized acquisition parameters and real-time image processing algorithms. Air kerma (AK), dose area product (DAP) and acquisition time for digital fluoroscopy (DF) and digital subtraction angiography (DSA) were recorded...

OBJECTIVE: To assess the current practice patterns of radiologists who perform transthoracic needle biopsy (TNB). MATERIALS AND METHODS: An email survey of 71 questions on TNB was sent to 240 members of the Korean Society of Thoracic Radiology. The answers to multiple-choice questions (n = 56) were analyzed. RESULTS: Of 60 respondents, 45% had 10 or more years of experience in chest radiology, and 70% had 5 or more years of experience in TNB...

A 54-year-old woman was found deceased with incised wounds of both sides of her neck and both wrists. Postmortem CT scanning revealed air in the heart and in the dural veins in continuity with air in the right jugular vein. Death was due to incised wounds of the wrist and neck with blood loss and air embolism. The manner of death was suicide. At autopsy, perfusion of the thoracic ascending aorta produced a fine stream of water emanating from an incised wound of the right ulnar artery with no significant leakage of water from the wound of the left wrist...

With the recent increase in the detection of small-sized lung nodules because of the widespread use of computed tomography (CT), limited resection and minimally invasive surgery are preferred by patients with these lesions. In particular, the detection of nodules that show ground-glass opacity during high-resolution CT has increased. Although lobectomy and lymph node dissection were the standard procedures used for treating lung cancer, limited wedge resection and segmentectomy have become acceptable for treating small-sized lung cancers with nodules showing ground-glass opacity...

BACKGROUND: Outflow control during laparoscopic liver resection necessitates the use of technically demanding procedures since the hepatic veins are fragile and vulnerable to damage during parenchymal transection. The liver hanging maneuver reduces venous backflow bleeding during deep parenchymal transection. The present report describes surgical outcomes and a technique to achieve outflow control during application of the modified liver hanging maneuver in patients undergoing laparoscopic left-sided hepatectomy...

BACKGROUND: Guide catheter extension systems have become one of the most powerful tools for addressing complex lesions during percutaneous coronary intervention (PCI), but data on a new-generation rapid exchange extension catheter - the Guidezilla catheter - are limited. Summarized herein reports on experience using the Guidezilla catheter for complex coronary lesions via a transradial approach at the documented institution an evaluation of its safety and efficacy. METHODS: A total of 25 patients (19 males and 6 females) who underwent PCI via the radial approach with the Guidezilla catheter for adequate back-up support and to facilitate equipment delivery were enrolled...

Diving air-breathing vertebrates have long been considered protected against decompression sickness (DCS) through anatomical, physiological, and behavioural adaptations. However, an acute systemic gas and fat embolic syndrome similar to DCS in human divers was described in beaked whales that stranded in temporal and spatial association with military exercises involving high-powered sonar. More recently, DCS has been diagnosed in bycaught sea turtles. Both cases were linked to human activities. Two Risso's dolphin (Grampus griseus) out of 493 necropsied cetaceans stranded in the Canary Islands in a 16-year period (2000-2015), had a severe acute decompression sickness supported by pathological findings and gas analysis...

OBJECTIVES: Oxygenator failure during cardiopulmonary bypass constitutes a life-threatening event, especially when perfusion is conducted under normothermia. An alternative solution to emergency oxygenator changeover is described. METHODS: A supplementary oxygenator is added in the venous line without interrupting perfusion. De-airing is achieved through the cardiotomy reservoir. Oxygen supply is adapted to ensure physiologic partial oxygen pressure. RESULTS: On 5 occasions in the past 4 years, Capiox Baby FX 05 oxygenator (n = 4) and Capiox FX15 (n = 1) failed to exchange blood gases after bypass run ranging from 290 min to 563 min...

Climate models predict greater increases in the frequency than in the amount of precipitation and a consequent rise in atmospheric humidity at high latitudes by the end of the century. We investigated the responses of hydraulic and relevant anatomical traits of xylem to elevated relative humidity of air on a 1-yr-old coppice of hybrid aspen (Populus×wettsteinii) growing in the experimental stand at the Free Air Humidity Manipulation site in Eastern Estonia. The hydraulic conductivity of stems was measured with a high pressure flow meter; artificial cavitation in the stem segments was induced by the air injection method...

The surface tension (γ) of xylem sap plays a key role in stabilizing air-water interfaces at the pits between water- and gas-filled conduits to avoid air seeding at low water potentials. We studied seasonal changes in xylem sap γ in Picea abies and Pinus mugo growing at the alpine timberline. We analyzed their vulnerability to drought-induced embolism using solutions of different γ and estimated the potential effect of seasonal changes in γ on hydraulic vulnerability. In both species, xylem sap γ showed distinct seasonal courses between about 50 and 68 mn m(-1) Solutions with low γ caused higher vulnerability to drought-induced xylem embolism...

BACKGROUND: Invasive fungal diseases (IFD) are an important cause of morbidity and mortality in immunocompromised patients, and early diagnosis and management are a challenge. We evaluated the clinical utility of computed tomography (CT)-guided percutaneous lung biopsies in diagnosing IFD. METHODS: Between 2003 and 2014, we analyzed 2671 CT-guided lung biopsies, from which 157 were IFD associated; we aimed to determine microbiological-based diagnostic accuracy of calcofluor white staining (CFWS), culture, Aspergillus antigen detection (GM), broad-range fungal PCR, and Aspergillus PCR per sample...

A Schoster
Intravenous catheterization is a necessity for continuous administration of intravenous fluids and for intermittent intravenous access to avoid discomfort and potential complications of repeated needle insertions into the vein. Intravenous catheterization is commonly performed and well tolerated in horses, but catheter associated complications have been reported. The most commonly reported complication is thrombophlebitis, but others such as venous air embolism, exsanguination and catheter fragmentation may also occur...
