With regard to the causes of non-traumatic hemoperitoneum, one must consider diseases that cause vascular lesions [1,2] some of which are systemic or multifocal [1-3]. Here, we describe a non-traumatic hemoperitoneum case in which the presence of dissection of splenic artery led to the finding of systemic vascular lesions. In the diagnosis and treatment of non-traumatic hemoperitoneum, this ins...

PURPOSE To characterize the MR appearance of the common hemangioma of infancy as well as low- and high-flow vascular malformations of the head and neck. PATIENTS AND METHODS Twenty patients with vascular lesions of the head and neck proved either by pathology, angiography, and/or unequivocal clinical diagnosis were included. Vascular lesions included 15 low-flow lesions (four hemangiomas, 10 ...

Background and study aims  Polypoid lesions found during upper gastrointestinal endoscopy (UGIE) are occasionally found in patients with portal hypertension (PH). This study aimed to assess the true nature of such polypoid lesions using endoscopic ultrasound (EUS) and determine the accuracy of UGIE in differentiating between vascular and non-vascular lesions in PH. Patients and methods  We re...

OBJECTIVE Enhanced endothelial permeability leading to intimal accumulation of low-density lipoproteins (LDL) stimulates the formation of atherosclerotic lesions. Histamine is known to increase vascular permeability. Whether this affects the formation of atherosclerotic lesions, however, remains elusive. METHODS AND RESULTS Apolipoprotein E-null (ApoE(-/-)) mice treated with a histamine H1 re...

BACKGROUND Conventional therapies for deep cutaneous vascular anomalies have demonstrated poor efficacy and many side effects. New laser systems offer greater potential to treat these difficult lesions, but the lack of specific treatment guidelines has restricted consistent success. OBJECTIVE To establish a rational, user-friendly algorithm that incorporates basic components of deep vascular ...

Two cases of mitral insufficiency are reported. In 1 case the lesion was produced by rupture of the chordae tendineae of the posterior leaflet of the mitral valve. In the other case it was produced by fibrous adhesion of the posterior leaflet of the mitral valve to the underlying left ventricular wall, which occurred during healing of subacute bacterial endocarditis. Changes occurred in the pul...

V lesions are of principal importance in the progression of various primary and secondary kidney diseases (1). In the majority of individuals with kidney diseases, vascular component, is involved secondarily in the disease process affecting primarily the glomeruli. Indeed, in IgAN as a common and progressive glomerulopathy, impaired kidney function, hypertension, proteinuria and interstitial fi...

The aim of this study was to explore the correlation between different degrees of renal vascular lesions in children with Henoch-Schönlein purpura nephritis (HSPN) and changes in progenitor cell number and function in peripheral blood. Forty-eight HSPN patients were divided into three groups, mild, moderate and severe, according to the degree of renal vascular lesions. Peripheral blood mononucl...

Vascular lesions were reviewed in 13 autopsied infants with congenital defects of maternal rubella. The characteristic finding was intimal fibromuscular proliferation. The internal elastic lamella and media were almost always unchanged, even in the presence of a greatly thickened intima. These arterial changes appeared to be unlike other vascular lesions described in infancy. Severe and extensi...

In the past, necrotizing vasculitis has been considered to be one of the dominant intrarenal vascular abnormalities in systemic lupus erythematosus (SLE). To test the validity of this statement, 70 consecutive renal biopsies from patients with SLE were reviewed. Light microscopy (LM) and immunofluorescence (IF) studies documented abnormalities, including thrombosis and nephrosclerosis, in 30 pa...
