Chronic obstruction of pulmonary arteries can be due to a variety of disease processes, including chronic thromboembolic disease, fibrosing mediastinitis, or neoplasia. Large vessel arteritis is another unusual cause of pulmonary artery obstruction and can be difficult to distinguish from the above-listed etiologies. We present four patients referred to our institution with the provisional diag...

The aim of the study was to present the usefulness of one tube reverse transcriptase polymerase chain reaction assay (RT-PCR) in comparison to virus isolation test (VI) in the detection of equine arteritis virus. The group of 82 semen samples taken from different stallions was examined. Equine arteritis virus was isolated in RK-13 cell monolayers from the seminal plasma of 11 animals. The same ...

Fatal Foam Cell Arteritis of the Brain After Irradiation for Hodgkin's Disease: Angiography and Pathology • A case of foam cell arteritis of the brain following irradiation of the neighboring structures for Hodgkin's disease is described. A differential diagnosis of the unique angiographical findings is presented. The etiology of foam cell arteritis restricted to the brain is considered. It is ...

Large vessel vasculitides, such as Takayasu arteritis and giant cell arteritis, affect vital arteries and cause clinical complications by either luminal occlusion or vessel wall destruction. Inflammatory infiltrates, often with granulomatous arrangements, are distributed as a panarteritis throughout all of the artery's wall layers or cluster in the adventitia as a perivasculitis. Factors determ...

Thirty consecutive patients with severe scleritis or episcleritis were admitted as in-patients to the Medical Ophthalmology Unit and assessed for systemic disease. There were seventeen women and thirteen men. The mean age was 53 with a median of 57 (range 23-83). Eighteen of the patients had scleritis: eleven of these had evidence of connective tissue disease and three of them had temporal art...

OBJECTIVES The objectives of this study were to develop a scoring system with colour Doppler ultrasound (CDUS) in patients with Takayasu's arteritis, to correlate the CDUS score with the Indian Takayasu's Activity Score (ITAS) and to assess the degree of agreement between CDUS and angiogram in the diagnosis of Takayasu's arteritis. METHODS Nineteen angiographically confirmed Takayasu's arteri...

This article describes the case of a 68-year-old patient suffering from giant cell arteritis (also known as Horton's arteritis or temporal arteritis). The patient came to our attention due to a large and sudden visual loss caused by the occlusion of major retinal arteries. The patient had neuralgic pain in the face. The next day, for a thorough examination, the patient went to the day hospital ...

background & aim: takayasu’s arteritis is a rare, chronic vasculitis, affecting women of reproductive age. with disease progression, evidence of vascular involvement and insufficiency becomes clinically apparent due to the narrowing or occlusion of the proximal or distal branches of the aorta. therefore, pregnancy-related complications, such as superimposed preeclampsia, renal failure, and cong...

To explore the role of adhesion molecules in mediating mononuclear cell localisation, development of the granulomatous reaction, and cell mediated damage to the arterial wall in giant cell arteritis, 17 temporal artery biopsy specimens were examined. Eleven showed the histological features of giant cell arteritis and six showed no evidence of arteritis. All were examined for the expression of L...

INTRODUCTION Takayasu's Arteritis, formerly known as "pulseless disease", is a chronic idiopathic vasculitis which affects the large vessels in the body. First described in the 1800's, this rare condition is more commonly found in Asian women in their 40's. The aorta and its main branches are the primary vessels affected, with the most typical features reflected as ischemia or aneurysm formatio...
