  • (17) After examining the cases reported in literature (Sacks, Barabas, Beighton Sykes), they point out that, contrary to what is generally believed, the syndrome is not rare and cases, sporadic or familial, of recurrent episodes of spontaneous rupture of the intestine and large vessels or peripheral arteries are frequent.

Villus


Definition:

  • (n.) One of the minute papillary processes on certain vascular membranes; a villosity; as, villi cover the lining of the small intestines of many animals and serve to increase the absorbing surface.
  • (n.) Fine hairs on plants, resembling the pile of velvet.
