RT Journal A1 INGRAHAM FD T1 LOcal morphologic changes following section of the thoracic sympathetic nerve trunk JF Archives of Surgery JO Archives of Surgery YR 1929 FD April 1 VO 18 IS 4 SP 1857 OP 1862 DO 10.1001/archsurg.1929.01140130959063 UL http://dx.doi.org/10.1001/archsurg.1929.01140130959063 AB The recently manifested interest in the surgery of the sympathetic nervous system has been stimulated largely by the work of Jonnesco (1922) concerning cervical sympathectomy for angina pectoris, of Leriche (1916) in regard to peri-arterial sympathectomy and of Hunter and Royle (1924) in their effort to relieve spastic paraplegia by ramisection. During the past two years, the division of a sympathetic trunk has been performed on a large scale, both experimentally and clinically, in an attempt to study and relieve various ill defined disorders. The following work was done with the purpose of determining the exact character of the local morphologic changes following simple section of such a trunk, especially with regard to neuroma formation.MATERIAL AND METHOD  The left thoracic sympathetic trunk was divided in thirty-two dogs and in seven cats. All the animals were full grown and in good health prior to operation, and their behavior after operation
