The joining of parts or sticking together—which may occur unnaturally in organs or tissues so that discomfort is caused. Adhesions may develop during the healing process following surgery. A non-elastic, fibrous tissue forms and
clings to the surface of adjoining organs causing them to fuse together or to kink. Usually adhesions are painless but, occasionally those causing kinking of the small intestine may produce an intestinal obstruction that must be removed by surgery.
Adhesions also may be formed in the subarachnoid space in the brain following meningitis or severe hemorrhage. These adhesions interfere with movement of the cerebrospinal fluid. Hydrocephalus may result; this then, must be eliminated by surgery.
