Endovascular treatment of intracranial aneurysms in patients 65 years or older: clinical outcomes.

BACKGROUND AND PURPOSE: A controversial discussion concerning treatment of aneurysms in elderly patients exists. The aim of this study was to analyze clinical outcome in patients older than 65 years harboring intracranial aneurysms after endovascular treatment. MATERIALS AND METHODS: A total of 108 patients aged 65 years or older (mean age, 72 years, range, 65-87 years) were selected for endovascular treatment between 1997 and 2005. A total of 85 (78.7%) patients had an acute subarachnoid hemorrhage (SAH). SAH was classified according to Hunt and Hess (HH) grade: I (n = 16), II (n = 11), III (n = 33), IV (n = 19), and V (n = 6). There were 69 aneurysms that were small; 46, medium; 8, large; and 5, giant. Occlusion rate was categorized as complete (100%), subtotal (95% to 99%), and incomplete (<95%) obliteration according to the Raymond scale. RESULTS: Endovascular treatment was technically feasible in 108 of 113 aneurysms. Complete occlusion could be achieved in 80 patients; basal remnant was seen in 26 patients and a dog ear in 2 patients. Procedural complications included thrombotic vessel occlusion (n = 9), aneurysmal rupture (n = 4), and stenosis of the parent vessel (n = 2). The Glasgow Outcome Scale (GOS) for the patients with SAH after 6 months was good recovery (n = 43), moderate disability (n = 12), severe disability (n = 28), persistent vegetative state (n = 5), and death (n = 18). Outcome for the patients with unruptured aneurysms was good recovery in all 23 patients. On follow-up digital subtraction angiography (DSA) in 69 patients, complete aneurysmal occlusion was confirmed in 81% after 6 months. Five patients with recanalization were re-treated with coiling. CONCLUSION: Endovascular treatment of ruptured and unruptured intracranial aneurysms in this subgroup was safe and effective.

[Epidural haematoma after operative evacuation of an acute subdural haematoma. Discussion of primary treatment illustrated by an unusual case]. / Epiduralhämatom nach Entlastung eines akuten Subduralhämatoms. Diskussion der Primärversorgung anhand eines ungewöhnlichen Falles.

Subdural haematomas as a consequence of severe head injury often constitute the indication for operative evacuation. Despite intensive care management postoperative computed tomography scans are essential. This is illustrated by an unusual case report of a patient suffering from an epidural haematoma after operation of an subdural haematoma. In addition, the importance of the skull X-ray in the emergency setting and intracranial pressure monitoring are discussed.

[Cerebrospinal fluid penetration of ofloxacin (Tarivid) in non-inflamed meninges]. / Die Liquorgängigkeit von Ofloxacin (Tarivid) bei nicht entzündeten Meningen.

In 9 patients, who underwent lumbar drainage after transsphenoidal surgery for pituitary adenoma, we collected 69 samples of CSF and plasma, respectively. The concentration of ofloxacin was measured bacteriologically. Considering the ofloxacin CSF and plasma levels related to time some aspects of pharmacokinetics are discussed. With maximum CSF concentrations coming up to 40% of plasma levels liquor penetrability is quite good. Ofloxacin seems to be able to prevent (postoperative) meningitis, even with grampositive Cocci.

Palliative occipito-cervical stabilization in patients with malignant tumors of the occipito-cervical junction and the upper cervical spine.

BACKGROUND: Occipital-cervical stability may be impaired in patients with primary malignant or metastatic tumors of the cranio-cervical junction and the upper cervical spine. The purpose of this study was to evaluate occipital-cervical fixation with pre-bent titanium-loops and sublaminar wiring in order to achieve a rigid and safe stabilisation of the occipito-cervical region in this group of patients. METHOD: 20 patients with severe impairment of occipito-cervical stability due to primary malignant or metastatic cervical bone involvement were included in this study. For palliation of symptoms, resulting from destructive instability, a stabilization procedure using Ransford Loops with sublaminar cable fixation was used in these patients as a palliative therapeutic concept. FINDINGS: Pain which was the major symptom in all patients treated, showed good and immediate response to the stabilization procedures. All 20 patients were either pain free or had good improvement with less intake of analgesic drugs. Signs of spinal cord compression like spasticity and quadraparesis were less likely to improve after surgery. However in 3 of 5 patients neurological function improved after surgery whereas in 2 patients no improvement was achieved. INTERPRETATION: In all patients with impaired occipito-cervical stability due to primary malignant or metastatic tumors of the occipito-cervical junction and the upper cervical spine, immediate stabilization resulting in an improvement of pain was achieved. Occipito-cervical stabilization using contoured Ransford loops is a promising palliative therapeutic concept in this group of patients.
