Tromboembolismo pulmonar masivo de alto riesgo asociado a foramen oval permeable High-risk massive pulmonary thromboembolism associated with patent foramen ovale. Directory of Open Access Journals Sweden. High mortality rate associated with massive pulmonary embolism requires an aggressive invasive approach including surgical pulmonary embolectomy when thrombolytic therapy has failed or is contraindicated. We describe a case of high-risk massive pulmonary embolism who underwent surgical treatment due to the presence of a mobile intracardiac clot in a patent foramen ovale , and the possible risk of paradoxical arterial embolism.

Tromboembolismo pulmonar masivo de alto riesgo asociado a foramen oval permeable. Perineural tumor extension through the foramen ovale. The third division of the trigeminal nerve exists through the foramen ovale and supplies extensive superficial and deep facial structures. As such, it is a common route of perineural spread of head and neck tumors.

Perineural tumor extension through basal foramina is well documented pathologically and has been described with multiple radiologic modalities. The authors present seven patients with transforaminal lesions evaluated with MR imaging.

Clinical findings referable to the two dimensions of V 3 are correlated with the images. This paper focuses on the normal anatomy and pathologic findings in and around the foramen ovale. Background and Purpose: A patent foramen ovale has been reported to be significantly more frequent in young stroke patients than in matched control subjects, and paradoxical embolism has been suggested as the main mechanism of stroke in-this situation.

The present study was designed to test this hypothesis. Methods: Sixty-eight consecutive patients under 55 years of age presenting with an ischemic stroke had an extensive workup, including transesophageal echocardiography with contrast.

We compared the prevalence of criteria for the diagnosis of paradoxical embolism in patients with and without a patent foramen ovale. Clinical evidence of deep vein thrombosis was present in one patient with a patent foramen ovale and in none of the others.

Our results do not support the hypothesis that paradoxical embolism is the primary mechanism of stroke in patients with a patent foramen ovale.

Patent foramen ovale and migraine attacks: a systematic review. Migraine headache and the presence of a patent foramen ovale have been associated with each other, although the precise pathophysiological mechanism s are uncertain. The purpose of this systematic review was to identify the extent of patent foramen ovale prevalence in migraineurs and to determine whether closure of a patent foramen ovale would improve migraine headache.

An electronic literature search was performed to select studies between January and February that were relevant to the prevalence of patent foramen ovale and migraine, and the effects of intervention s on migraine attacks.

Of the initial articles presented by the initial search, 20 satisfied the inclusion criteria assessing patent foramen ovale prevalence in migraineurs and 21 presented data on patent foramen ovale closure. In case series and cohort studies, patent foramen ovale prevalence in migraineurs ranged from Case-control studies reported a prevalence ranging from The extent of improvement or resolution of migraine headache attack symptoms was variable.

In case series, intervention ameliorated migraine headache attack in One single randomized trial did not show any benefit from patent foramen ovale closure.

The data overall do not exclude the possibility of a placebo effect for resolving migraine following patent foramen ovale closure. This systematic review demonstrates firstly that migraine headache attack is associated with a higher prevalence of patent foramen ovale than among the general population. Observational data suggest that some improvement of migraine would be observed if the patent foramen ovale were to be closed.

A proper assessment of any interventions for patent foramen ovale closure would require further large randomized trials to be conducted given uncertainties from existing trial data.

All rights reserved. Full Text Available Dyspnea accounts for more than one-fourth of the hospital admissions from Emergency Department. Less common etiologies include conditions such as valvular heart disease, pulmonary embolism, and right-to-left shunt RLS from patent foramen ovale PFO. RLS can also occur in absence of higher right atrium pressure.

We report one such case that highlights the importance of high clinical suspicion, thorough evaluation, and percutaneous closure of the PFO leading to significant improvement in the symptoms. Full Text Available Abstract We present a case of a year-old female with deep vein thrombosis after abdominal surgery.

The patient quickly developed severe pulmonary embolism and stroke representative of paradoxical embolism. Echocardiography showed a thrombus straddling a patent foramen ovale , which was confirmed intraoperatively. An accurate diagnosis and rapid treatment decisions are crucial for preventing patient deterioration in the form of new pulmonary embolisms or stroke. Percutaneous closure of patent foramen ovale in cryptogenic embolism.

The options for secondary prevention of cryptogenic embolism in patients with patent foramen ovale are administration of antithrombotic medications or percutaneous closure of the patent foramen ovale. We investigated whether closure is superior to medical therapy. We performed a multicenter, superiority trial in 29 centers in Europe, Canada, Brazil, and Australia in which the assessors of end points were unaware of the study-group assignments.

Patients with a patent foramen ovale and ischemic stroke, transient ischemic attack TIA , or a peripheral thromboembolic event were randomly assigned to undergo closure of the patent foramen ovale with the Amplatzer PFO Occluder or to receive medical therapy.

The primary end point was a composite of death, nonfatal stroke, TIA, or peripheral embolism. Analysis was performed on data for the intention-to-treat population. The mean duration of follow-up was 4. The primary end point occurred in 7 of the patients 3. Nonfatal stroke occurred in 1 patient 0.

Closure of a patent foramen ovale for secondary prevention of cryptogenic embolism did not result in a significant reduction in the risk of recurrent embolic events or death as compared with medical therapy. Funded by St. Jude Medical; ClinicalTrials. Transcatheter closure of a patent foramen ovale PFO reduces the risk of recurrent cryptogenic stroke compared with medical therapy.

PFO closure is a prophylactic procedure, and will not provide the patient with symptomatic improvement, except in cases of hypoxemia due to right-to-left shunt or possibly migraine headaches. Therefore, appropriate patient selection is critical, and procedural safety is paramount. Herein, we review key characteristics of the devices currently available for transcatheter PFO closure within the United States, and highlight key technical aspects of the PFO closure procedure that will maximize procedural success.

A thrombus in transit through a patent foramen ovale. Although many patients with PFO are asymptomatic and do not require treatment, paradoxical embolism can cause stroke or myocardial infarction.

The authors report an unusual case of PFO with a transversing thrombus in an year-old man. The patient's initial presentation appeared clinically as acute coronary syndrome, but he was subsequently diagnosed with a massive thrombus in transit via a PFO and pulmonary embolus leading to right-sided heart failure.

The aim of the present study was to evaluate the echocardiographic follow-up of patent foramen ovale , which is considered a potential etiological factor in various diseases, and to determine the factors affecting spontaneous closure.

Between January and June , records of patients with patent foramen ovale were retrospectively reviewed. Patency of less than 3 mm around the fossa ovalis is called patent foramen ovale. Patients with cyanotic congenital heart diseases, severe heart valve disorders and severe hemodynamic left to right shunts were excluded from the study. The patients were divided into three groups based on age; 1 day-1 month in group 1, 1 month months in group 2, and more than 12 months in group 3.

Of the patients, Defect was spontaneously closed in However, ventricular septal defect and spontaneous closure of patent foramen ovale had a positive correlation p closure rate of patent foramen ovale is high. Furthermore, a positive correlation was found between spontaneous closure of patent foramen ovale with early diagnosis and small defect size. Study of DSA-guided percutaneous puncture location of foramen oval. Objective: To study the technique of digital substraction angiography DSA -guided percutaneous puncture location of foramen oval.

Methods: 39 cases of trigeminal neuralgia were included in the study from Feb. The patients were punctured by the amending anterior position. The f0ramen oval was displayed by moving the tube tilted degree to the caudal and degree to the healthy side. The direction and depth of the needles was determined on the lateral view. Then, radio-frequency thermocoagulation therapy was performed.

Results: The needles were located in oval foramen in all the patients. Pain disappeared in 36 cases, alleviated in other cases, and no serious complication occurred during therapy.

Conclusions: Oval foramen locations by DSA can improve the successful rate of operation. The foramen oval can be clearly displayed by DSA-guided in amending position, with comfortable position for patients.

We investigated the effect of PFO closure combined with antiplatelet therapy versus antiplatelet therapy alone on the risks of recurrent stroke and new Imaging of the brain was performed at the baseline screening and at 24 months. The coprimary end points were freedom from clinical evidence of ischemic stroke reported here as the percentage of patients who had a recurrence of stroke through at least 24 months after randomization and the month Sex differences in cryptogenic stroke with patent foramen ovale.

Sex differences in patients with patent foramen ovale PFO and cryptogenic stroke have not been systematically analyzed. We aimed to determine sex influences on demographics, vascular risk factors, clinical manifestations, stroke location, and clinical outcome. One thousand two hundred eighty-eight consecutive patients with ischemic stroke or transient ischemic attack TIA were admitted to a single stroke center.

All patients underwent a complete stroke workup including clinical examination, standard blood tests, cerebral and vascular imaging, transesophageal echocardiography, and hour electrocardiography. Stroke severity and the prevalence of risk factors did not differ between the 2 sexes. There was an independent association between male sex and stroke location in the posterior cerebral circulation OR 3.

Men and women did not differ in respect to PFO grade, prevalence of right-to-left shunt at rest, or coexistence of atrial septal aneurysm. Clinical outcome at 3 months was similar in both sexes. Patent foramen ovale was more prevalent in men than in women with cryptogenic stroke.

There were no sex influences on age, risk factors, echocardiographic characteristics of PFO, or clinical outcome. Male sex was independently associated with stroke in the posterior cerebral circulation.

Establishment of a porcine model of patent foramen ovale. Objective: To investigate the feasibility of developing an animal model of patent foramen ovale PFO in piglets by percutaneous atrial septal puncture and balloon dilation.

Enfermedad arterial periférica (PAD)

Acute basilar artery thrombosis ABT has been largely considered a neurological catastrophe. An early presumptive diagnosis is essential to avoid treatment delay. Either multiparametric magnetic resonance imaging or computed tomography angiography source images may represent valid non-invasive tools to confirm ABT and evaluate ischemic tissue viability.. The main determinant of ABT outcome is early recanalization but the most effective therapeutic option remains to be clarified. Therefore, in the absence of contraindications, intravenous thrombolysis should be started as soon as possible and can be used as the main therapy when interventional procedures are not available.
