[Omentomyelosynangiosis--a direct intraoperative observation].
The late outcome of implantation of the vascular omental pedicle on the injured spinal cord performed in 7 patients to improve functional recovery through revascularization of the injured cord tissue is reported. All the patients were reoperated at the same spinal level 2-5 years after the omental pedicle implantation for the treatment of chronic neuropathic spinal pain by employing DREZ (Dorsal Root Entry Zone lesion) surgery. From the technical standpoint it was necessary to mobilize the implanted omental pedicle from the cord surface to provide the access to dorsolateral cord sulcus for the DREZ operation. Mobilization of the omental pedicle provided unique opportunity to observe omental-cord contact surface (omentomielosinangiosis) that is believed to stimulate revascularization of the cord tissue. In our report particular attention was paid to the specificity of the omental-cord contact surface and the late tissue changes of the cord as well as omental tissue knowing the fact that the capacity of omental tissue to stimulate neoangiogenesis still represents the actual doubt in neurobiological theory and practice. Detailed analysis of the actual neurological condition of these patients compared to neurological condition assessed before the implantation of the pediculated-vascular omental graft revealed neither sensory nor motoric improvement (in the postimplantation period). The effect of DREZ surgery of the chronic neuropathic spinal pain was not a topic of this report.
