OBJECTThe objective of this study was to investigate epidemiology and outcome after surgical treatment for spinal injuries in Ethiopia.METHODSMedical records of patients who underwent surgery for spine injuries at Myungsung Christian Medical Center in Addis Ababa, Ethiopia, between January 2008 and September 2012 were reviewed retrospectively. Assessment of outcome and complications was determined from patient consultations and phone interviews.RESULTSA total of 146 patients were included (129 males, 17 females). Their mean age was 31.7 years (range 15–81 years). The leading cause of injury was motor vehicle accidents (54.1%), and this was followed by falls (26.7%). The most common injury sites were lumbar (41.1%) and cervical (34.2%) regions of the spine. In 21.2% of patients, no neurological deficit was present before surgery, 46.6% had incomplete spinal cord injury (American Spinal Injury Association [ASIA] Impairment Scale [AIS] Grade B-D), and 32.2% had complete spinal cord injury (AIS Grade A). Follow-up was hampered by suboptimal infrastructure, but information regarding outcome was successfully obtained for 110 patients (75.3%). At follow-up (mean 22.9 months; range 2–57 months), 25 patients (17.1%) were confirmed dead and 85 patients (58.2%) were alive; 49 patients (33.6%) underwent physical examination. At least 8 of the 47 patients (17.0%) with a complete injury and 29 of the 68 patients (42.6%) with an incomplete injury showed neurological improvement. The reported incidences of pressure wounds, recurrent urinary tract infections, pneumonia, and thromboembolic events were 22.5%, 13.5%, 5.6%, and 1.1%, respectively.CONCLUSIONSPatients showed surprisingly good recovery considering the limited resources. Surgical treatment for spine injuries in Ethiopia is considered beneficial.
Introduction: Delayed cerebral ischemia (DCI) is a major cause of disability and death after aneurysmal subarachnoid hemorrhage. The literature suggests that impaired cerebrovascular reactivity (CVR) may be a predictor for DCI; still no CVR based prediction model has been developed. Increased knowledge about possible predictors of DCI can improve patient management in high-risk patients and allow for shorter hospital stay in low-risk patients. Method: CVR was examined in 42 patients with aneurysmal subarachnoid hemorrhage and 37 patients treated for unruptured intracranial aneurysm, using acetazolamide test with transcranial Doppler monitoring of blood flow velocities. Patients were followed for development of DCI, separated into clinical deterioration and radiographic infarction. Results: For all patients, regardless of aneurysm rupture status, CVR was on average 5.5 percentage points lower on the ipsilateral side of aneurysm treatment. Patients with clinical deterioration due to DCI had lower CVR than patients without DCI, and the difference was larger on the contralateral side (33.9% vs. 49.2%). Two prediction models were constructed for clinical deterioration due to DCI. The area under the receiver operating characteristic curve was 0.82 in the model using established predictors, and 0.86 in the model that also included CVR.
Conclusion:Our findings support the hypothesis that impaired CVR may be an independent predictor of clinical deterioration due to DCI, and may assist in identifying patients at risk after aneurysmal subarachnoid hemorrhage. Ipsilateral CVR reduction occurs in all patients after aneurysm treatment, regardless of DCI development, thus highlighting the need to evaluate ipsi-and contralateral CVR separately.
