Acute lung injury associated with systemic inflammatory response syndrome following subarachnoid hemorrhage: a survey by the Shonan Neurosurgical Association.

Acute lung injury (ALI) associated with systemic inflammatory response syndrome (SIRS) is a systemic complication following subarachnoid hemorrhage (SAH), but the incidence and influence on prognosis are unclear. The incidences of SIRS and ALI were surveyed in a prospective multicenter study of 96 patients admitted for SAH between December 2004 and June 2007. Hunt and Hess grade and Glasgow Outcome Scale score were also investigated. Forty-eight patients were diagnosed with SIRS, and 26 developed ALI within 4 weeks of admission. Nineteen of the 26 patients with ALI were complicated by SIRS, and 7 developed only ALI. Thirteen of the 19 patients complicated by SIRS and ALI died, and this mortality was higher than for patients with only SIRS (3/29) and only ALI (1/7). Multivariate analysis of the development of SIRS and/or ALI and Hunt and Hess grade as risk factors associated with aggravation of the outcome showed that complication with SIRS and ALI had the highest risk. Half of the patients admitted for SAH developed SIRS, and more than 25% developed ALI. The prognosis for patients complicated by SIRS and ALI was poor, which indicates that prevention and active treatment of these two pathologies are important.

Lumboperitoneal shunt placement using computed tomography and fluoroscopy in conscious patients.

The authors have developed a minimally invasive lumboperitoneal shunt placement procedure conducted after administration of a local anesthetic. The procedure involves placing a guide wire and a peel-away sheath under fluoroscopic and CT guidance. Between June 2004 and August 2006, 40 patients (21 men and 19 women; mean age 72.5 years [range 33-86 years]) underwent surgery. A Codman Hakim programmable valve system (82-3844, Codman & Shurtleff, Inc.) was used for the procedure. The mean operating time was 53 minutes, and 7 patients (17.5%) developed shunt dysfunction complications. These complications comprised an infected shunt valve in 2 patients, postoperative lower-limb pain in 1 patient, and shunt obstruction (caused by debris and hemorrhage) at the ventral and lumbar ends in 2 patients each. This procedure is less invasive than conventional lumboperitoneal shunt insertion and could be performed as an outpatient surgery for treatment of idiopathic normal-pressure hydrocephalus.

[A case of idiopathic thoracic spinal cord herniation].

We report a case of idiopathic thoracic spinal cord herniation. A 63-year-old female came to our hospital complaining of a slowly progressive gait disturbance that began 5 years ago. She showed signs of a left dominant spastic paraparesis and sensory disturbance. Her left foot had already became a drop foot from 2 years ago. Magnetic resonance (MR) imaging and computed tomographic (CT) myelography demonstrated that the atrophic spinal cord had displaced to the ventral side with a dilated dorsal subarachnoid space at T2-3 level. Surgery was performed via T2-3 laminoplastic laminectomy. The ventral aspect of the spinal cord revealed a defect in the inner layer of the duplicated dura mater, into which the gliotic spinal cord herniated. The herniated spinal cord was repositioned and the dural defect was repaired using a GORE-TEX dura substitute. Postoperative course was uneventful. Although the patient showed marked improvement in the right lower limb, there was slight improvement in the left lower limb. The clinical symptoms of this disease are uncommon and progress slowly, and if left untreated will result in paraparesis. Therefore early diagnosis and operation is important to prevent the progression of symptoms and to achieve a satisfactory outcome.
