Saccular Aneurysms

✓ The authors report a follow-up review of 1000 cases of intracranial definitive surgery for saccular aneurysms. The prognosis for such surgical cases is discussed. Postoperative results at least 6 months after discharge from the hospital were analyzed in 876 (93.3%) of the 939 surviving patients. The longest follow-up period was 14 years and 5 months, with an average of 3 years and 7 months. At the time of discharge, there were 543 excellent results, 186 good, 117 fair, 93 poor, and 61 deaths. The chief findings were as follows: 1) Most of the patients determined as “excellent” or “good” at discharge were able to return to normal life; most of the deaths or instances of worsened condition found in the follow-up study were due to new lesions. 2) Fully 62% of the cases determined as “fair” at discharge were found in an improved state at the follow-up study, having returned to normal life. 3) Only 19% of cases determined as “poor” at discharge had improved to the point where a return to normal life was possible, the majority having died or remaining in poor condition.

Csf Leaks

Object. Spontaneous spinal cerebrospinal fluid (CSF) leaks are an increasingly recognized cause of intracranial hypotension and may require neurosurgical intervention. In the present report the authors review their experience with the surgical management of spontaneous spinal CSF leaks. Methods. Between 1992 and 1997, 10 patients with spontaneous spinal CSF leaks and intracranial hypotension were treated surgically. The mean age of the seven women and three men was 42.3 years (range 22–61 years). Preoperative imaging showed a single meningeal diverticulum in two patients, a complex of diverticula in one patient, and a focal CSF leak alone in seven patients. Surgical exploration in these seven patients demonstrated meningeal diverticula in one patient; no clear source of CSF leakage could be identified in the remaining six patients. Treatment consisted of ligation of the diverticula or packing of the epidural space with muscle or Gelfoam. Multiple simultaneous spinal CSF leaks were identified in three patients. Conclusions. All patients experienced complete relief of their headaches postoperatively. There has been no recurrence of symptoms in any of the patients during a mean follow-up period of 19 months (range 3–58 months; 16 person-years of cumulative follow up). Complications consisted of transient intracranial hypertension in one patient and leg numbness in another patient. Although the disease is often self-limiting, surgical treatment has an important role in the management of spontaneous spinal CSF leaks. Surgery is effective in eliminating the headaches and the morbidity is generally low. Surgical exploration for a focal CSF leak, as demonstrated on radiographic studies, usually does not reveal a clear source of the leak. Some patients may have multiple simultaneous CSF leaks.

Object. The cause and indication for enlargement of chronic subdural hematomas (CSDHs) have remained unresolved. The authors observed a black band on the inner membrane of a CSDH on T2*-weighted magnetic resonance (MR) images obtained in patients with symptoms. After surgical treatment, the band disappeared. The T2*-weighted sequence of MR imaging is an excellent diagnostic tool for detecting ferromagnetic substances, but it is rarely performed in cases of a CSDH. The authors speculate that the black band may be associated with the development of CSDH. Methods. To investigate how the black band observed on T2*-weighted MR images contributes to the development of a CSDH, 59 lesions in 50 patients with CSDH (41 men and nine women, mean age 70 ± 11 years [range 48–93 years]) were investigated prospectively. The incidence of black bands on the first T2*-weighted MR image obtained in patients with symptomatic CSDH was 97% (31 of 32 CSDHs), which was significantly higher than that associated with asymptomatic CSDH (11% [three of 27 CSDHs], p < 0.001). The black bands associated with symptomatic CSDH disappeared soon after surgical treatment in 31 CSDHs and became fainter in another. In two instances the CSDH recurred with reappearance of the band. Twenty-four of 27 asymptomatic CSDHs had no accompanying black band. Follow-up MR images demonstrated a later formation of bands in two of 24 asymptomatic CSDHs that enlarged to symptomatic size. Logistic regression analysis revealed that the heterogeneity and thickness of the CSDH on computerized tomography scans were independently and significantly associated with the black band. Conclusions. The dynamics of the black band may depend on the enlargement or shrinkage of the CSDH.

✓ Two cases of dural arteriovenous malformation of the tentorial apex are presented. Both were treated surgically by means of a sinus skeletonization technique. The operative technique included a combined bioccipital and median suboccipital craniotomy in which the posterior third of the superior sagittal and the straight and bilateral transverse sinuses were skeletonized by incising the falx and the tentorium along the sinuses. Endovascular embolization was used prior to the surgical approach in one case. Clinical and angiographic cure was achieved in both patients, with a follow up of 4 years in the first case and 1 year in the second one. The surgical technique is described in detail.

Object. The surgical treatment of metastatic spinal tumors is an essential component of the comprehensive care of cancer patients. In most large series investigators have focused on the treatment of thoracic lesions because 70% of cases involve this region. The lumbar spine is less frequently involved (20% cases), and it is unclear whether its unique anatomical and biomechanical features affect surgery-related outcomes. The authors present a retrospective study of a large series of patients with lumbar metastatic lesions, assessing neurological and pain outcomes, complications, and survival. Methods. The authors retrospectively reviewed data obtained in 139 patients who underwent 166 surgical procedures for lumbar metastatic disease between August 1994 and April 2001. The impact of operative approach on outcomes was also analyzed. Among the wide variety of metastatic lesions, pain was the most common presenting symptom (96%), including local pain, radicular pain, and axial pain due to instability. Patients underwent anterior, posterior, and combined approaches depending on the anatomical distribution of disease. One month after surgery, complete or partial improvement in pain was demonstrated in 94% of the cases. The median survival duration for the entire population was 14.8 months. Conclusions. The surgical treatment of metastatic lesions in the lumbar spine improved neurological and ambulatory function, significantly reducing axial spinal pain; results were comparable with those for other spinal regions. Analysis of results obtained in the present study suggests that outcomes are similar when the operative approach mirrors the anatomical distribution of disease. When lumbar vertebrectomy is necessary, however, anterior approaches minimize blood loss and wound-related complications.

✓ A survey of 89 patients with subdural empyema was conducted to assess the incidence of late seizures and morbidity in this disease. Twenty-four patients died during the acute stage of the illness and, of the 65 survivors, 13 were lost or had incomplete follow-up review. Hemiparesis occurred in 48 of the survivors during the acute stage, and all but nine recovered completely. Thirteen patients had a visual field deficit and all recovered; in three of these 13 who had speech disorders the deficits persisted. Recovery from neurological morbidity was not related to the type of surgical treatment; however, the mortality rate was improved by craniotomy. The same incidence of early seizures occurred in those who died (62%) as in those who survived (63%). Of those who had no early seizures, 42% had late seizures, the majority appearing within 16 months. Of those who had early seizures, 71% did not have subsequent attacks. The highest incidence of seizures occurred in patients who had their empyema in the second and third decades of life. The incidence of late seizures was not influenced by the method of surgical treatment, the degree of deterioration of consciousness during the acute stage of the illness, nor by occurrence of early seizures. A significantly increased incidence of early seizures was associated with paranasal sepsis, but not with late seizures.
