Does heparin induce release of phospholipase A ( 2 ) into the splanchnic circulation?
Heparin, given in the dosage required for cardiopulmonary bypass, caused release of phospholipase A(2) into the splanchnic circulation.
Both methods did not show difference in efficacy of leg pain relief during follow-up (1.7--8.5 years). 16.7% of patients after fusion of more than 2 segments had pain above and below fusion area in long-term postoperative period. Such pain was not observed in group 2. One patient of the 1st group had fixation system destruction that required repeated intervention. Groups have not difference in back pain severity after surgery on 1 segment. Also less intraoperative blood loss and duration of surgery were established in group 2.
