Acute severe headache indicative of subarachnoid haemorrhage (SAH), but without the requisite proof, is defined as thunderclap. A special pathophysiological mechanism for the development of this headache is not known as yet. This retrospective study comprised 84 patients. ⋯ Thunderclap headache has no diagnostic or prognostic specificity and therefore we recommend use of this term only as a description of the headache characteristic. Thunderclap headache is not a predictor of a future SAH. Cerebral angiography should be restricted to cases with neurological deficits.

To present clinical manifestations of Terson's syndrome and the results of treatment of vitreous hemorrhages with the use of intravitreous injections of anti-Rh serum. ⋯ Intravitreous injections of anti-Rh serum can be the method of choice in the treatment of vitreous hemorrhages in Terson's syndrome with no tendency for spontaneous resorption and without proliferative vitreoretinopathy.

Hypertensive hypervolemic therapy has been shown to reverse delayed ischemic deficits after aneurysmal subarachnoid hemorrhage. Concern has been raised about systemic complications of therapy, including pulmonary edema and myocardial ischemia, especially when high doses of vasopressors are used. Patients in whom delayed ischemic deficits were treated with hypervolemia and phenylephrine were prospectively evaluated for signs of systemic toxicity. ⋯ Hypertensive hypervolemic therapy with the use of high-dose phenylephrine can be administered with acceptable systemic toxicity, even in patients with previous cardiac disease, provided that close monitoring is performed. To minimize risk, aggressive treatment should probably be reserved for patients with signs of delayed ischemia rather than administered prophylactically.

Prognostic value of the amount of post-traumatic subarachnoid haemorrhage in a six month follow up period.
Clinical and radiological patterns from 148 patients with post-traumatic subarachnoid haemorrhage (TSAH) were analysed with specific regard for the amount and distribution of blood in subarachnoid spaces to verify if these variables have any influence on overall outcome. The degree and extent of TSAH were classified according to Fisher's criteria: in 93 patients it was grade 1, in 36 grade 2, in 13 grade 3, and in six grade 4. ⋯ The results of the present study confirm that TSAH is a negative prognostic factor. Whereas the degree of TSAH is mainly related to clinical conditions at admission, the presence of subarachnoid blood clots both in basal cisterns and over the cerebral convexity indicates a poor outcome.
