ANALYSIS OF BLOOD LOSS AFTER VENTRAL AND POSTERIOR CORRECTIVE SPINAL FUSION IN PATIENT WITH IDIOPATHIC SCOLIOSIS

It was prospective analysis of 36 patients with idiopathic scoliosis in order to compare the intraoperative and early postoperative blood loss after ventral and posterior corrective spinal fusion. All patients were divided into two groups: group 1 ? 18 patients (14 females and 4 males) with a mean age of 17,2 ± 3,4 years treated with ventral corrective spinal fusion and group 2 ? 18 patients (17 females and 1 male) with a mean age of 15,9 ± 3,4 years with posterior corrective spinal fusion. Mean values and standard deviation of the time of surgery, intraoperative blood loss, transfusion volume, hemoglobin, blood volume loss and drainage loss and number of fused spinal levels were evaluated. The results were compared using the Mann-Whitney test (p ? 0,05). It was found that group 1 had a lower intraoperative blood loss, the average volume of blood transfusion and blood loss drain in the early postoperative period compared with group 2. It was concluded that ventral corrective spinal fusion is associated with less intraoperative and early postoperative blood loss which is probably due to the less traumatic access and length of the spine instrumentation.
