Background: Although coronarography is still the gold standard to evaluate coronary lesions, it remains a bidimensional representation of a tridimensional complex structure, which can represent a source of error in measurements.
Aims: to perform a correlation and concordance study between quantitative coronary angiography (QCA) and intravascular ultrasound measurements for intermediate and ambiguous lesions.
Methods: We analysed 40 patients' coronary arteries from March 2009 to November 2011 by both QCA and intravascular ultrasound to perform then a correlation and concordance study.
Background: Coronarography presents some limits in assessing intermediate stenosis. Intravascular ultrasound provides tridimensional measurements of the artery, with more reliable data guiding revascularization decision.
Aims: to evaluate the impact of intravascular ultrasound measurements on revascularization decision of intermediate and ambiguous coronary lesions.
Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands. It is usually a benign, slow-growing and well-circumscribed tumour. However, PA may occasionally give rise to metastases that usually occur after a previous recurrence.
