This prospective trial was designed to evaluate the incidence of Terson syndrome in patients suffering from subarachnoid hemorrhage, intracerebral hemorrhage, or traumatic brain injury and whether consequences necessarily derive from the intraocular hemorrhage itself. Two ophthalmologic examinations were performed to identify patients with Terson syndrome. Data on initial Glasgow Coma Scale, Hunt and Hess and Fisher grades, aneurysm site and diameter, and volume of hemorrhage in intracerebral hemorrhage patients were correlated to the location and course of Terson syndrome. Follow-up was performed after 3 months, including clinical and ophthalmologic investigations. The data showed that 16 of 83 subarachnoid hemorrhage patients (19.3%), 2 of 22 intracerebral hemorrhage patients (9.1%), and 1 of 32 traumatic brain injury patients (3.1%) suffered from Terson syndrome. Low Glasgow Coma Scale (p = 0.002), high Hunt and Hess grade (p < 0.001), and high Fisher grade (p = 0.002) were found to be associated with a higher incidence of Terson syndrome. The neurological outcome in subarachnoid hemorrhage patients suffering from Terson syndrome was worse compared with that of subarachnoid hemorrhage patients without Terson syndrome (p = 0.005), and vitrectomy was performed in seven eyes of six patients due to poor visual acuity. Terson syndrome is underestimated in patients with subarachnoid hemorrhage and a rare pathology in intracerebral hemorrhage as well as in traumatic brain injury patients. Spontaneous regression of the intraocular hemorrhage may be seen, but in half of the patients, vitrectomy is necessary to prevent permanent visual deterioration.
BackgroundPeripheral nerve injury (PNI) as an adjunct lesion in patients with upper extremity trauma has not been investigated in a Central European setting so far, despite of its devastating long-term consequences. This study evaluates a large multinational trauma registry for prevalence, mechanisms, injury severity and outcome characteristics of upper limb nerve lesions.MethodsAfter formal approval the TraumaRegister DGU® (TR-DGU) was searched for severely injured cases with upper extremity involvement between 2002 and 2015. Patients were separated into two cohorts with regard to presence of an accompanying nerve injury. For all cases demographic data, trauma mechanism, concomitant lesions, severity of injury and outcome characteristics were obtained and group comparisons performed.ResultsAbout 3,3% of all trauma patients with upper limb affection (n = 49,382) revealed additional nerve injuries. PNI cases were more likely of male gender (78,6% vs.73,2%) and tended to be significantly younger than their counterparts without nerve lesions (mean age 40,6 y vs. 47,2 y). Motorcycle accidents were the most frequently encountered single cause of injury in PNI patients (32,5%), whereas control cases primarily sustained their trauma from high or low falls (32,2%). Typical lesions recognized in PNI patients were fractures of the humerus (37,2%) or ulna (20,3%), vascular lacerations (arterial 10,9%; venous 2,4%) and extensive soft tissue damage (21,3%). Despite of similar average trauma severity in both groups patients with nerve affection had a longer primary hospital stay (30,6 d vs. 24,2 d) and required more subsequent inpatient rehabilitation (36,0% vs. 29,2%).ConclusionPNI complicating upper extremity trauma might be more commonly encountered in Central Europe than suggested by previous foreign studies. PNI typically affect males of young age who show significantly increased length of hospitalization and subsequent need for inpatient rehabilitation. Hence these lesions induce extraordinary high financial expenses besides their impact on health related quality of life for the individual patient. Further research is necessary to develop specific prevention strategies for this kind of trauma.
Background Aneurysmal subarachnoid hemorrhage (SAH) as a serious type of stroke is frequently accompanied by a so-called initial thunderclap headache. However, the occurrence of burdensome long-term headache following SAH has never been studied in detail so far. The aim of this study was to determine the prevalence and characteristics of long-term burdensome headache in good-grade SAH patients as well as its relation to health-related quality of life (HR-QOL). Methods All SAH cases treated between January 2014 and December 2016 with preserved consciousness at hospital discharge were prospectively interviewed regarding burdensome headache in 2018. Study participants were subsequently scrutinized by means of a standardized postal survey comprising validated pain and HR-QOL questionnaires. A retrospective chart review provided data on the initial treatment. Results A total of 93 out of 145 eligible SAH patients participated in the study (62 females). A total of 41% (38/93) of subjects indicated burdensome headache at follow-up (mean 32.6 ± 9.3 months). Comparison between patients with (HA+) and without long-term headache (HA-) revealed significantly younger mean age (47.9 ± 11.8 vs. 55.6 ± 10.3 years; p < .01) as well as more favorable neurological conditions (WFNS I/II: 95% vs. 75%; p = .03) in HA+ cases. The mean average headache of the HA+ group was 3.7 ± 2.3 (10-point numeric rating scale), and the mean maximum headache intensity was 5.7 ± 2.9. Pain and HR-QOL scores demonstrated profound alterations in HA+ compared to HA-patients. Conclusions Our results suggest that a considerable proportion of SAH patients suffers from burdensome headache even years after the hemorrhage. Moreover, long-term headache is associated with reduced HR-QOL in these cases. Keywords Headache. Intracranial aneurysm. Quality of life.

Blister-like internal carotid artery (ICA) aneurysms are known for their fragile and thin-walled morphology associated with a high risk of intraprocedural rupture. Neurosurgical and endovascular options are illustrated on three exemplary cases reviewing the diagnostic and therapeutic implications of these special aneurysms. A 49-year-old woman was admitted with subarachnoid hemorrhage (SAH) in which angiography showed a broad-based, small bulging ectasy of the terminal ICA segment. On the attempt of surgical clipping, the aneurysm ruptured leaving a tear in the ICA. After temporary clipping, the rims of the tear were approximated by sutures. Sufficient closure of the remaining leakage was achieved by circumferential wrapping which was secured by two clips. Postoperative angiography confirmed stenosis of the tightened ICA and patient recovered without neurological deficit. Surgical attempt on a second case with bulging of the C4-segment topped by a small aneurysm was fatal due to extensive laceration of the basal ICA intraoperatively. Endovascular stenting was the choice of treatment in a third SAH patient in which angiography was suspicious of a blister-like ICA aneurysm. Six-month follow-up was uneventful; the patient recovered well and further growth of bulging was not seen. Reviewing the literature, blister-like aneurysms tend to arise at uncommon sites not located at the arterial branches. Small and broad-based bulges with or without true saccular aneurysms have to be assessed as characteristic features of blister-like aneurysms. Rupture of the aneurysm involving the carrying artery has to be considered during therapeutic attempts, in which urgent strategies have to be kept in reserve preventing fatal outcome. Blister-like aneurysms is a hazardous affair for neurosurgeons and neuroradiologists as their fragile structure most likely will lead to intraoperative rupture. If endovascular treatment is not promising, wrapping and revascularization techniques come true to still be an important part of the neurosurgeons toolbox for reconstructing a vessel lumen and preserving a sufficient cerebral blood flow.
BackgroundNerve lesions are well known reasons for reduced functional capacity and diminished quality of life. By now only a few epidemiological studies focus on lower extremity trauma related nerve injuries. This study reveals frequency and characteristics of nerve damages in patients with leg trauma in the European context.MethodsSixty thousand four hundred twenty-two significant limb trauma cases were derived from the TraumaRegister DGU® between 2002 and 2015. The TR-DGU is a multi- centre database of severely injured patients. We compared patients with additional nerve injury to those with intact neural structures for demographic data, trauma mechanisms, concomitant injuries, treatment and outcome parameters.ResultsApproximately 1,8% of patients with injured lower extremities suffer from additional nerve trauma. These patients were younger (mean age 38,1 y) and more likely of male sex (80%) compared to the patients without nerve injury (mean age 46,7 y; 68,4% male). This study suggests the peroneal nerve to be the most frequently involved neural structure (50,9%). Patients with concomitant nerve lesions generally required a longer hospital stay and exhibited a higher rate for subsequent rehabilitation. Peripheral nerve damage was mainly a consequence of motorbike (31,2%) and car accidents (30,7%), whereas leg trauma without nerve lesion most frequently resulted from car collisions (29,6%) and falls (29,8%).ConclusionDespite of its low frequency nerve injury remains a main cause for reduced functional capacity and induces high socioeconomic expenditures due to prolonged rehabilitation and absenteeism of the mostly young trauma victims. Further research is necessary to get insight into management and long term outcome of peripheral nerve injuries.
The results suggest that lesions of the right insular cortex are associated with reduced sensitivity for the perception of dyspnea and pain, in particular for their perceived unpleasantness. This underlines the importance of the insular cortex for the perception of both sensations.
Improvement in pain seemed to be most important aspect in ACDF patients regarding the subjective SQ. Therefore, we strongly recommend focusing on pain-reducing therapies when choosing treatment for these patients during the postoperative period.
While meningiomas are known as slow-growing extracerebral neoplasms, the subgroup of secretory meningiomas with histologically benign characteristics tend to cause disproportional peritumoral edema, frequently leading to severe medical and neurological complications in postoperative management. Among 1,484 meningiomas that were resected at our institution between 1990 and 2007, 44 (3%) patients were found to have the histological diagnosis of a secretory meningioma. The clinical course, radiological appearance, and histopathological features were retrospectively analyzed to examine the specifics of these benign lesions. Meningiomas were located at the convexity (n = 14), the cranial base (18), and the sphenoid ridge (12). A severe, nearly hemispheric perifocal edema disproportional to tumor size was seen on preoperative MR imaging in 18 (41%) patients. Following surgical resection, the postoperative course was uneventful in 29 patients. In 15 patients, severe peritumoral edema continued or even increased on postoperative CT imaging. Six patients showed midline shift and clinical worsening necessitating respirator-assisted ventilation and intracranial pressure monitoring. An association between the extent of brain edema and number of periodic acid Schiff-positive pseudopsammomas was found (p < 0.02). Further, the size of the edema correlated with the number of immunohistochemically detected cells expressing carcinoembryonic antigen (CEA) and cytokeratin (CK) (p < 0.01). Mean MIB-1 (Ki-67 antigen) proliferation index was 3.0% (range, 0%-17%) and did not correlate with edema or tumor recurrence. Secretory meningiomas are frequently associated with severe peritumoral edema. The extent of edema correlates with immunohistochemically detected expression of CEA and CK. Extended perifocal edema in meningiomas is an unusual finding and should alert the neurosurgeon that surgery may aggravate edema excessively, leading to a life-threatening postoperative situation.
