Traumatic Aneurysms of the Pericallosal Artery: Report of Two Cases

Two cases of the traumatic aneurysms of the pericallosal artery that occurred after closed head injury are reported. The mental deterioration, urinary in continence and crural-predominent hemiparesis are attributable to the delayed intracranial hemorrhage after rupture of the traumatic aneurysms of the pericallosal artery. As soon as the diagnosis has been confirmed by the cerebral angiography, surgical treatment is recommended to reduce the high mortality and morbidity and the procedure as in the congenital aneurysm.

Posterior Lumbar Interbody Fusion

The authors present 4 cases of spondylolisthesis, 1 case of spondylolysis and 2 cases of Tbc spondylitis of lower lumbar spine treated by posterior lumbar interbody fusion, with follow-up periods of 3 months to 2 years. All cases had severe low back pain. Other common manifestations were radiating pain to leg. All cases were treated with laminectomy, which included a mesial facetectomy followed by posterior lumbar interbody fusion. The spondylolisthesis was reduced to zero degrees in three cases by the use of vertebral spreader. The fusion rate of intervertebral space in radiological finding was 100%. On case become pain free, 4 cases had mild degree of pain, 1 case had moderate degree of pain and 1 case was not improved. The authors conclude that posterior lumbar interbody fusion is applicable as a surgical treatment of patient with spondylolisthesis and Tbc spondylitis.
