BACKGROUND Infantile hemangioma is the most common benign, self-limiting tumour of childhood. Treatment is reserved for hemangiomas that obstruct vital structures or cause significant disfigurement. Traditionally, corticosteroids have been the medical treatment of choice. Since 2008, however, propranolol has been rapidly adopted as an effective pharmacological treatment for infantile hemangioma...

Bronchial artery embolization is an effective nonsurgical therapy for massive hemoptysis. Routine selection of the bronchial arteries from the aorta usually enables the interventionalist full interrogation and embolization of the culprit vascular abnormality. In problematic cases where bronchial artery access is difficult, a systemic-to-pulmonary arterial shunt can be exploited as a retrograde ...

1. Analysis of relationships between blood volume, vascular capacitance, cardiopulmonary and peripheral blood volumes, labelled albumin disappearance rate, plasma renin activity, blood pressure and age was performed in essential hypertensive males. 2. The results indicate that capacitance bed constriction probably occurs with age in essential hypertension leading to an increase in the product b...

vascular endothelial growth factor (vegf) is a multifunctional cytokine with distinct functions in angiogenesis, lymphangiogenesis, vascular permeability, and hematopoiesis. vegf is a highly conserved, disulfide-bonded dimeric glycoprotein of 34 to 45 kda produced by several cell types including fibroblasts, neutrophils, endothelial cells, and peripheral blood mononuclear cells, particularly t ...

purpose : to determine the association between retinal vascular diameter and its branching angles with diabetic retinopathy (dr) stages in diabetic patients methods : a descriptive analytic cross-sectional study was conducted in 62 diabetic patients (120 eyes) referred to farabi eye hospital between june 2008 and december 2009. digital fundus photography pictures were imported into photoshop so...

PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...

Neonates with pulmonary atresia and intact interventricular septum (PAIVS) do not have pulmonary vascular disease secondary to their heart abnormality. Persistent pulmonary hypertension of the newborn has not been described in association with this condition. The case is reported of a female neonate born with PAIVS, who preoperatively had no clinical evidence or any risk factors for persistent ...

A well defined lung mass with clear margins and no other signs such as lymphadenopathy, pulmonary infiltration, consolidation, collapse or bone involvement usually indicates a benign lesion, whether a tumour such as an adenoma (carcinoid), cyst or vascular abnormality. Bronchogenic, pericardial and hydatid cysts do not show contrast enhancement, adenomas do enhance but not as significantly as v...

non‑recurrent laryngeal nerve (nrln) is a rare anomaly which is reported in 0.3%‑0.8% of people on the right side and in 0.004% (extremely rare) on the left side. damage to this nerve during the surgical procedure may lead to severe iatrogenic morbidity and should therefore be prevented from being damaged. the best way to avoid this damage to the nerve is to identify the nerve with a systematic...

A generalised vasoconstriction, for almost a century believed to be the basis of all types of human hypertension, was disproved by recent haemodynamic studies. In our investigation of hypertension in chronic parenchymatous non-uraemic, non-anaemic renal disease, we have established that the earliest haemodynamic abnormality in subjects, of whom over 90% later develop high blood pressure, has ac...
