Presentation was in the form of a cerebrovascular accident (CVA). Clinical presentations and management strategies of PAVF with associated CAVM are broadly discussed along with a pertinent literature review. [ncbi.nlm.nih.gov]

  […] and suffered a seizure during a practice, leading to him being diagnosed with AVM. [19] Actor Ricardo Montalbán was born with spinal AVM. [20] During the filming of the 1951 film Across the Wide Missouri, Montalbán was thrown from his horse, knocked unconscious [en.wikipedia.org]

• Platypnea

  We describe a case of a rare clinical disorder, platypnea-orthodeoxia syndrome. A 57-year-old man was admitted with progressive dyspnea. [ncbi.nlm.nih.gov]

  In view of the platypnea-orthodeoxia and family history of PAVMs associated with HHT, a provisional diagnosis of PAVMs associated with HHT was made. [ispub.com]

  Approximately 1/3 of patients demonstrate orthodeoxia, but platypnea is seldom observed. Differential diagnosis Differential diagnoses include pulmonary artery aneurysms, pulmonary varices, bronchoceles and vascular tumors. [orpha.net]

  The signs and symptoms of Pulmonary Arteriovenous Fistula include: Shortness of breath: Increased shortness of breath in upright position (platypnea), relieved by lying down Chest pain, cough that may contain blood in phlegm (hemoptysis) Migraine headaches [dovemed.com]

  If the patient becomes significantly desaturated in the upright position, the patient also demonstrates platypnea, which is dyspnea in the upright position, although this symptom is seen only in advanced cases. [emedicine.medscape.com]

  Conclusion Pulmonary AV malformation is a rare disorder and a rare cause of hemoptysis caused by congenital or acquired lesions in the lungs. [jacpjournal.org]

  Resumen Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is an autosomal dominant vascular disease that can be associated with pulmonary arteriovenous fistulas. [repositorio.uchile.cl]

  Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is an autosomal dominant vascular disease that can be associated with pulmonary arteriovenous fistulas. [scienceopen.com]

  He had no history of smoking or thrombotic vascular diseases. In physical exam the patient had normal vital signs. He had left-side facial palsy and hemi paresis. He was dysarthric and complained of diplopia when looking to the right side. [advbiores.net]

Platypnea-orthodeoxia syndrome is rare, and patients with this syndrome require an extensive workup to determine its cause. [ncbi.nlm.nih.gov]

It is beyond the scope of this text to discuss the entire workup and management of an HHT patient. 8 Our goal is to provide a basic guide to performing PAVF embolization with the current embolic technology available. [radiologykey.com]

A PaO2 of > 90 mm Hg and a SO2 > 96.5% rule out any significant shunt, while a PaO2 < 85 mm Hg or a SO2 < 96% indicate a potential shunt fraction of > 5%. ( 9 ) Significant shunt fraction measurement of >5% necessitate workup by Contrast Echocardiography [ispub.com]

• X-Ray Abnormal

  Therefore, the presence of P-AVF in stroke patients who have normal physical findings and no chest x ray abnormalities cannot be excluded. [jnnp.bmj.com]

  Therefore, the presence of P-AVF in stroke patients who have normal physical findings and no chest x ray abnormalities cannot be excluded. [jnnp.bmj.com]

• Arterial Oxygen Saturation Decreased

  While breathing room air, arterial oxygen saturation decreased from 92% in a recumbent position to 83% in an upright position. [ncbi.nlm.nih.gov]

Large pulmonary arteriovenous fistula (PAVF) manifests as cyanosis and predisposes to serious complications of right-to-left shunt, and therefore necessitates early treatment. [ncbi.nlm.nih.gov]

Angiographic treatment has become the mainstay of therapy for most patients during the last decade. It is less invasive and can be repeated easily. [scienceopen.com]

In the same patient, both methods of treatment for PAVF were all satisfactory, and each has advantages and indications. [journalmc.org]

With the increased blood flow in pregnancy such fistulas enlarge, occasionally giving rise to haemothorax, which generally has a poor prognosis. [ncbi.nlm.nih.gov]

Prognosis With appropriate management and interventions, prognosis is generally very good with many patients reaching their 9th and 10th decades of life. During pregnancy, however, there is a 1% maternal death rate. [orpha.net]

Treatment and prognosis Treatment options include: trans-catheter coil embolization surgery (historically treated with surgery) Once successfully treated (embolotherapy, surgical resection), prognosis is generally good for an individual lesion. [radiopaedia.org]

[…] history with this disease Epistaxis common Telangiectasia of skin and mucus membrane GI bleeding TIA Stroke Cerebral abscess secondary to loss of pulmonary filter function Hemothorax 2° rupture of subpleural AVM Polycythemia Congestive heart failure Prognosis [learningradiology.com]

The analysis of a concomitant occurrence of these abnormalities may be useful in elucidating the etiology of pulmonary arteriovenous fistula. [ncbi.nlm.nih.gov]

Etiology The exact pathogenesis is still unknown. Although generally observed in the context of HHT, PAVMs may also be idiopathic. [orpha.net]

This implies that the pathophysiology of the arteriovenous malformations in these conditions is dilation of the normal capillary bed. [emedicine.medscape.com]

PATHOPHYSIOLOGY In contrast to systemic arteriovenous malformation, PAVMs do not affect cardiac haemodynamics. 12, 13, 16 Cardiac output, cardiac index, pulmonary capillary wedge pressure, heart rate, blood pressure, and the electrocardiogram are usually [pmj.bmj.com]

The major concern when operating on a patient with a neurologically symptomatic pulmonary arteriovenous fistula (PAVF) is how to prevent a thromboembolic event during surgery. [ncbi.nlm.nih.gov]
