Twenty-one patients were submitted to investigate serum complements (CH50, C3, C4) after aneurysmal subarachnoid hemorrhage during a 2 to 3-week period. As for the control, the same examination was carried out in patients with non-subarachnoid hemorrhage such as hypertensive intracerebral hemorrhage. There was no remarkable changes of serum complements in the control patients. ⋯ Ce and C4 level of the patients without symptomatic vasospasm did not change markedly after subarachnoid hemorrhage during the investigation, while they decreased severely in patients with severe vasospasm and major neurological deficit. The patients with mild symptomatic vasospasm without major neurological deficit showed transient decrease of C3 and C4 level in the period of 5 to 10 days after subarachnoid hemorrhage. These data show that sequential determinations of serum complements (C3 and C4) level after subarachnoid hemorrhage is a useful method for the choice of therapy, and for the prognosis of aneurysmal patients after subarachnoid hemorrhage.

Fifty patients with subarachnoid hemorrhage (SAH) were evaluated, with attention to past history, age, sex, time from the onset of symptoms to hospital admission, etiology of SAH, diagnostic procedures, therapy and outcome. Of these, 16 who showed ventricular dilatation in the CT during their evolution were analyzed. ⋯ Ten patients required definitive shunt; in 7 of them, SAH had been caused by arterial aneurysm. All had a grade higher than 3 in Hunt and Hess' scale and only one half received fibrinolytic drugs during their treatment.

Subarachnoid hemorrhage occurs in 1%-2% of patients with neurological complications from sickle cell disease. The authors report a case of subarachnoid hemorrhage in a 13-year-old black girl with sickle cell disease. ⋯ Angiography revealed no evidence of aneurysm but multiple stenosis and/or occlusions of the distal branches of the anterior and middle cerebral arteries bilaterally. Rupture of leptomeningeal collateral vessels is a possible cause of subarachnoid hemorrhage in our patient.

Two cases of spinal subarachnoid haematoma occurring after spinal anaesthesia are reported. In the first case, lumbar puncture was attempted three times in a 81-year-old man; spinal anaesthesia trial was than abandoned, and the patient given a general anaesthetic. He was given prophylactic calcium heparinate soon after surgery. ⋯ The patient died on the following day. Both these cases are similar to those previously reported and point out the role played by anticoagulants. Because early diagnosis of spinal cord compression is difficult, the prognosis is poor, especially in case of paraplegia.
