The purpose of this investigation was to evaluate the functional relationship between the volume and the size of the orifice of small saccular aneurysms such as those found intracranially. There is reason to believe that the relationship between those individual values plays an important,though as yet undefined, part in intra-aneurysmal hemodynamics. Little note is made in the literature of interior aneurysmal measurements save as depicted in drawings or arteriographically. While arteriorgraphy is of value in estimating aneurysmal volume in the functioning state, it has been somewhat less effective in outlining the orifice. An experimental entry to the problem seemed advisable, and this is a report of experience with 21 experimental aneurysms, each of which had a different chamber-volume to orifice-area relationship as expressed mathematically by V/A. Their patency or subsequent thrombosis was evaluated with reference to that quotient.

Closed intratendinous ruptures of flexor tendons are uncommon. Two such cases that occurred within the lumbrical origin are reported. Accurate history taking and clinical examination usually enable the site of rupture to be determined. Ultrasound examination can also help to localize the site. The role of the lumbrical, extrinsic flexors and trauma in the aetiology of the rupture are discussed. Acute suppurative tenosynovitis of the hand Diagnosis with ultrasound. Radwlogv 162,741-2. 13.
