AIMS To evaluate the role of magnetic resonance imaging (MRI) in the assessment of children with suspected extrinsic tracheobronchial compression due to vascular anomalies. METHODS Retrospective case note review in a tertiary referral centre. Twenty nine children who underwent dynamic laryngotracheobronchoscopy (DLTB) and were found to have a clinical suspicion of extrinsic tracheobronchial c...

OBJECTIVE Since the unexpected results from the Women's Health Initiative, the possible protective role of estrogen in preventing heart disease in perimenopausal and postmenopausal women is uncertain. This study examined atherosclerotic lesion development in ovariectomized versus follicle-depleted ovary-intact cholesterol-fed female low-density lipoprotein (LDL) receptor-deficient mice. METHO...

OBJECTIVES Direct aortic deployment of a transcatheter aortic valve eliminates the need to traverse the aortic arch with the valve delivery system, enables placement of large sheaths in the aorta and innominate artery, provides maximal precision during deployment and ensures a safe, conventional surgical aortotomy closure. We describe the initial experience with the Suprasternal Aortic Access S...

Tracheo-innominate artery fistula (TIAF) is rare, yet the most fatal complication after tracheostomy. In the absence of immediate diagnosis and surgical management, the mortality rate is very high, because the complication can lead to sudden massive tracheal hemorrhage. Tracheal obstruction and hypovolemic shock are the major life threatening conditions. The 46-year-old woman received tracheost...
