Subarachnoid-Subarachnoid (S-S) Bypass Versus Adhesion Lysis in Spinal Arachnoiditis and Syringomyelia

Condition(s) studied

Investigational drug(s) / intervention(s)

Subarachnoid-Subarachnoid (S-S) Bypass: The dura was widely exposed beyond the level of trauma, and then a midline dural opening was made under an operative microscope. When dura and arachnoid were adhered because of an expansion of arachnoiditis, they had to be released with great care to place the bypass tubes. During this procedure, S-S bypass was not usually needed to performed arachnoid lysis. This exposure had to reach the normal arachnoid mater free from arachnoiditis and adhesion, with normal CSF circulation. After dissections of the normal arachnoid mater at the cephalic and caudal sites, 1 or 2 tubes made of medical grade silicone (ventricular drainage tube; internal diameter 1.5-2.0 mm, external diameter 2.5-3.3 mm) were inserted into the cephalic and caudal ends of the normal subarachnoid space. The part of the tube inserted into the subarachnoid space was approximately 2 cm long.

Intradural Adhesion Lysis: Intradural spinal cord Adhesion Lysis

Study summary

To determine whether Subarachnoid-Subarachnoid (S-S) Bypass results in better patient outcomes with fewer complications and improved quality of life compared to intradural adhesion lysis in individuals with Spinal Arachnoiditis and Syringomyelia.
