| dc.description.abstract | Techniques and materials for repair of dural defects following neurosurgical procedures vary. Given higher complication rates with nonautologous duraplasty materials, most authors strongly recommend autologous grafts. To expand the arsenal of possible materials available to the neurosurgeon, we propose the use of autologous clavipectoral fascia as an alternative donor for duraplasty. Eight embalmed adult cadavers underwent dissection of the pectoral region. A 12-cm curvilinear skin incision was made 2 cm inferior to the nipple in males and along the inferior breast edge in females. Dissection was continued until the clavipectoral fascia was encountered, and a tissue plane was developed between this fascia and the deeper pectoralis major muscle. Sections of clavipectoral fascia were used for duraplasty in the same specimens. In all specimens, removal of clavipectoral fascia was easily performed with tissue separation between the overlying fascia and underlying muscle. Only small adhesions were found between the fascia and underlying muscle, and these were easily transected. No obvious gross neurovascular injuries were identified. Large portions of clavipectoral fascia were available, and at least a 10 x 10-cm piece (average thickness, 1.2 mm) was easily harvested for all specimens. Clavipectoral fascia shares characteristics with materials such as pericranium and fascia lata that have been used successfully in duraplasty, and most importantly, it is autologous. Theoretically, using clavipectoral fascia would reduce the risk of muscle herniation. It offers an alternative source for autologous dural grafting when other sources are unavailable or exhausted. Clinical experience with this fascia is warranted. | |
