Arteriovenous malformations of the lung are rare pulmonary vascular disorders which can suddenly lead to life threatening complications. Haemothorax due to rupture of a pulmonary arteriovenous malformation (PAVM) is very rare. We report here a case of a 39 year-old lady who presented with an acute onset of shortness of breath due to right-sided massive haemothorax and was subsequently detected ...

OBJECT The appropriate management of unruptured intracranial arteriovenous malformations (AVMs) remains controversial. In the present study, the authors evaluate the radiographic and clinical outcomes of radiosurgery for a large cohort of patients with unruptured AVMs. METHODS From a prospective database of 1204 cases of AVMs involving patients treated with radiosurgery at their institution, ...

Brain arteriovenous malformation (AVM) is an important cause of hemorrhagic stroke. The etiology is largely unknown and the therapeutics are controversial. A review of AVM-associated animal models may be helpful in order to understand the up-to-date knowledge and promote further research about the disease. We searched PubMed till December 31, 2014, with the term "arteriovenous malformation," li...

Patients: 601 patients (mean age 64 y, 57% men) who were conscious, had a computed tomography–confirmed spontaneous lobar ICH (volume 10 to 100 mL) ≤ 1 cm from the cortical surface of the brain, and presented ≤ 48 hours after ictus. Exclusion criteria included hemorrhage that was intraventricular, due to arteriovenous malformation confirmed by angiography or an aneurysm, secondary to tumor or t...

A placental site trophoblastic tumor requires care in management and a prompt diagnosis. Placental site trophoblastic tumor is a rare type of gestational trophoblastic disease and displays non-specific presentations similar to those of uterine arteriovenous malformation and those of non-neoplastic gestational trophoblastic diseases such as placental polypoid tumor. Diagnosis from biopsy is extr...

Pulmonary arteriovenous malformation is an abnormal communication between artery and a vein, causing clinical manifestations, such as chronic hypoxemia embolic events. Arteriovenous malformations were treated surgically, with significant rate of complications. In the 1970 ́s, first percutaneous catheter embolization was performed coils. We describe three cases in which techniques effective to pr...

Cerebral Arteriovenous Malformation (CAVM) hemodynamic in disease condition results changes in the flow and pressure level in blood vessels. Cerebral Arteriovenous Malformation (CAVM) is an abnormal shunting of vessels between arteries and veins. It is one of the common Brain disorder. In general, the blood flows of cerebral region are from arteries to veins through capillary bed. This paper is...

A 29-yr-old patient with hereditary haemorrhagic telangiectasia was referred to the present authors' centre with progressive exertional dyspnoea. Pulmonary arterial hypertension (PAH) was suspected on Doppler echocardiography and confirmed by right heart catheterisation demonstrating severe PAH. Genetic analysis found an activin receptor-like kinase-1 gene missense mutation. Chest radiography a...

CONTEXT Although rare, a pancreatic arteriovenous malformation can have serious consequences. A diagnosis of arteriovenous malformation requires evidence of aberrant communication between the arterial and the venous systems. This report describes a case where the use of multi-detector row CT and specific post-processing methods provided a diagnosis of arteriovenous malformation. This minimally ...
