Acute lower extremity ischemia from septic emboli is a surgical emergency. Timely diagnosis and management are critical to improve patient outcome. However, traditional diagnostic modalities such as intraoperative angiogram are time-consuming, require special equipment and personnel, and introduce contrast exposure for critically ill patients. There are limited reports of utilization of point-of-care ultrasound to detect peripheral septic emboli. We present a case where femoral occlusive septic emboli were identified by point-of-care ultrasound after mitral valve replacement...

PURPOSE: To narratively review published information on prevention, detection, pathophysiology, and appropriate treatment of vascular air embolism (VAE). MATERIALS AND METHODS: MEDLINE, SCOPUS, Cochrane Central Register and Google Scholar databases were searched for data published through October 2016. The Manufacturer and User Facility Device Experience (MAUDE) database was queried for "air embolism" reports (years 2011-2016). RESULTS: VAE may be introduced through disruption in the integrity of the venous circulation that occurs during insertion, maintenance, or removal of intravenous or central venous catheters...

BACKGROUND AND PURPOSE: Thrombus composition has been postulated to affect the success of endovascular therapy. Calcified clots are composed of large amounts of calcium phosphate which influences their mechanical properties and may serve as a model for testing this hypothesis. The aim of this study was to evaluate the recanalization and complication rates of calcified thromboemboli in patients with acute ischemic stroke who underwent thrombectomy. MATERIAL AND METHODS: A retrospective analysis was performed of all calcified intracranial thromboemboli in patients suffering an acute ischemic stroke, referred for endovascular therapy at two centers between January 2013 and July 2016...

BACKGROUND: Many clinicians utilize the strategy of prophylactically placing an endovascular balloon prior to transvenous lead extraction, yet there is no data regarding this practice. OBJECTIVE: This study assesses long-term outcomes of prophylactic placement of an endovascular balloon in the venae cavae of patients during transvenous lead extraction. METHODS: From April 2016 to March 2017, data was prospectively collected at two international cardiovascular centers on patients who had the balloon prophylactically placed in the venae cavae...

Cerebrovascular complication is the one of the most dreadful complication after open heart surgery which leads to significant decrease of quality of life even if the patients survived. To decrease these complications, carotid doppler echo as one of the non-invasive carotid screening modalities is effective. Carotid artery stenosis is common in the patients with coronary artery disease, and it is more frequent in the patients with more complexed coronary artery lesions. The more the patients indicated for coronary artery bypass grafting has complexed lesions these days, the more the patients have carotid artery lesions...

Here, we present the case of a patient with the findings of an early intracardiac thrombus and a pulmonary embolus after major trauma. A large clot was identified extending from the inferior vena cava into the right atrium and ventricle in the setting of preserved right ventricular function. Post-traumatic intracardiac thrombus is extremely rare and no comparable cases have previously been described in the absence of a congenital heart defect and obvious myocardial injury. Best practice afterpost-traumatic intracardiac thrombus is not well established but we found that early inferior vena cava filter placement and treatment with therapeutic coagulation resulted in clinical improvement, resolution of the thrombus and no further emboli...

Successful implantation of a total artificial heart relies on multiple standardized procedures, primarily the resection of the native heart, and exacting preparation of the atrial and vascular conduits for pump implant and activation. Achieving secure pump connections to inflow/outflow conduits is critical to a successful outcome. During the connection process, however, air may be introduced into the circulation, traveling to the brain and multiple organs. Such air emboli block blood flow to these areas and are detrimental to long-term survival...

A case of the Budd Chiary Syndrome (BCS) in a 43-yr-old man with hydatid cyst (HC) in the liver is reported from Imam Ali Hospital, Kermanshah, western Iran in 2016. This case was complicated by inferior vena cava (IVC) thrombosis, right atrial clot and pulmonary emboli. Compression of IVC was the likely mechanism. Abdominal ultrasonography revealed a huge HC located in segments near IVC and caused compression of IVC. Transthoracic echocardiography (TTE) revealed IVC and right atrium thrombosis, however pulmonary emboli was not documented in TTE but intra operative exploration showed multiple clot in main and left pulmonary artery branch...

Over the past three decades, lubricious (hydrophobic and/or hydrophilic) polymer-coated devices have been increasingly adopted by interventional physicians and vascular surgeons to access and treat a wider range of clinical presentations. Recent clinical literature highlights the presence of polymer coating emboli within the anatomy - a result of coating separation from an intravascular device - and associates it with a range of adverse clinical sequelae. The 2015 U.S. Food and Drug Administration safety communication titled "Lubricious Coating Separation from Intravascular Medical Devices" acknowledges these concerns and concludes that it will work with stakeholders to develop nonclinical test methodologies, establish performance criteria, and identify gaps in current national and international device standards for coating integrity performance...

Fusobacterium necrophorum is the oropharyngeal pathogen usually associated with Lemierre's syndrome, a pharyngeal infection which evolves to sepsis, septic emboli and thrombophlebitis of the adjacent neck vessels. It is an uncommon causative bacteria of a liver abscess, and an extensive workup should, therefore, be performed in order to rule out potential sources of the infection. This case report describes the workup that led to the diagnosis of a colorectal carcinoma, which was deemed to be the source of the Fusobacterium bacteraemia...

BACKGROUND: Thoracic aortic mural thrombus (TAMT) of the descending aorta is rare but can result in dramatic embolic events. Early treatment is therefore crucial; however, there is not a consensus on ideal initial treatment. METHODS: A review of the literature using PubMed was conducted, and all relevant publications describing descending TAMT of the past 15 years were reviewed. Variables included for this analysis were presentation, initial treatment strategy employed, outcome measures of thrombus resolution or regression, recurrence of symptomatic emboli, and mortality...

BACKGROUND: The aorta is a significant source of cerebral thromboembolisms. Aortic complicated lesions (ACLs) are key findings on transesophageal echocardiography (TEE) for assessing aortic sources of emboli to the brain. TEE is sometimes avoided due to its invasiveness. However, few reports have examined alternative methods for predicting ACLs. We investigated relationships between aortic arch calcification (AAC) on chest X-ray and ACLs. METHODS: Participants comprised 300 patients with acute ischemic stroke or transient ischemic attack who underwent TEE for the evaluation of the aortic arch and heart...

Squamous cell carcinoma (SCC) is well documented in snow leopards ( Uncia uncia ) and most common locations are oral, facial, or pedal. These two cases illustrate an unusual auricular presentation, which is more often reported in white domestic cats. The animals were aged and presented clinical signs of otitis such as head shaking and ear scratching. Clinical examinations showed auricular canal masses with chronic purulent otitis. In both cases, clinical deterioration led to euthanasia and histology of the ear canal was consistent with SCC and showed numerous vascular emboli...

BACKGROUND: Uterine leiomyosarcomas are very rare and highly aggressive tumors that have a high rate of recurrence and poor prognosis, even when early diagnosed. Due to their relative rarity, there is limited research on optimal management strategies. CASE PRESENTATION: A 60-year-old woman with a history of an asymptomatic uterine leiomyoma presented in October 2015 with postmenopausal bleeding and a friable vaginal cyst that bled when palpated. A partial cystectomy was performed, and malignant-like cystic and solid components were identified...
