spi·der an·gi·o·ma

spider angioma

Etymology: ME, spithre + Gk, angeion, vessel, oma, tumor
a form of telangiectasis characterized by a central elevated red dot the size of a pinhead from which small blood vessels radiate. Spider angiomas are often associated with elevated estrogen levels, such as occur in pregnancy or when the liver is diseased and unable to detoxify estrogens. Also called spider nevus. See also telangiectasia.
A superficial spider-like cluster of capillaries composed of a central ‘feeder’ vessel and multiple minute tortuous and dilated radiating vessels with a peripheral erythaema; when the involved vessel is large, it may pulsate and blanch on pressure; while classically due to increased circulating oestrogens as seen in pregnancy and alcoholic cirrhosis, SAs may occur in chronic hepatic congestion 2º to constrictive pericarditis and may be a normal birthmark in children

We would like to emphasize on the importance of using less traumatic methods instead of an adhesive tape to fix the tube on patients with spider angioma or facial telangiectasia as well as indicate the possible mechanical harms of the Trendelenburg position during laparoscopic procedures in order to avoid similarly disheartening situations, albeit of no clinical importance.
