Functional and quality of life evaluation after single level cervical discectomy and fusion or cervical artificial disc replacement.

PURPOSE: To evaluate and compare clinical, functional and quality of life (QOL) outcomes after two types of surgical approach for single level cervical disc herniation: anterior cervical discectomy andfusion (ACDF) with cage and cervical artificial disc replacement (C-ADR). METHOD: 119 patients with cervical disc herniation underwent surgery from January 2007 to December 2010; 55 patients were included in the study (27 ACDF, 28 C-ADR). We performed: a pre and postoperative clinical evaluation of cervicobrachial pain, motor and sensory deficit in the upper limbs; a functional and QOL evaluation with self assessment scales (VAS, NPNQ, SF-36); a postoperative instrumental evaluation of cervical ROM and pain. Mean follow-up period was 24 months. RESULTS: After surgery both groups showed clinical, functional and QOL improvement. No pre and postoperative differences were found between the groups. The postoperative instrumental evaluation showed a globally reduced cervical ROM and a decreased pain threshold in comparison with normal values in both groups. CONCLUSION: Our results demonstrate the clinical equivalence of the two surgical techniques and the satisfaction of the two groups of patients two years after surgery. Although functional changes persist after surgery they do not affect quality of life.

Functional assessment and quality of life before and after pulmonary endoarterectomy.

PURPOSE: The study investigates Quality of Life (QOL) and correlation with functional status of patients affected by Chronic Thromboembolic Pulmonary Hypertension who undergo Pulmonary Endoarterectomy. METHODS: We investigated with an observational design (before surgery, three and twelve months afterwards) the hemodynamic data (NYHA class, mean pulmonary arterial pressure, cardiac output and pulmonary vascular resistance), the functional status (using the 6-Minute Walk Test) and the QOL, using three questionnaires: Medical Outcome Study Short Form-36 (SF-36), Minnesota Living with Heart Failure Questionnaire (MLHFQ), Saint George Respiratory Questionnaire (SGRQ). We report the results of forty-nine patients. RESULTS: After surgery there was an improvement on functional and hemodynamic parameters and on QOL. The physical domain (PCS) of SF-36 was weakly but significantly associated with all functional parameters. There was no association between functional parameters and mental domain (MCS) of SF-36 or SGRQ. The improvement in 6-Minute Walk Distance was associated with an increase in MLHFQ. CONCLUSIONS: Both QOL and submaximal exercise tolerance improve after surgery. However only the physical domains of SF-36 appear to be significantly associated to the functional data.
