    Management problems in aneurysmal subarachnoid haemorrhage.
    (1988) Golek, Jerzy.; van Dellen, James Rikus.; Bullock, Malcolm Ross.; Kennedy, W. F. C.
    A retrospective review was made of the case records, angiograms and computed tomography (CT) relating to a total of 263 patients with subarachnoid haemorrhage (SAH) due to ruptured berry aneurysms who were admitted to the Department of Neurosurgery, Wentworth Hospital during the four years 1983-1986. The part of the thesis concerning vasospasm (VS) includes two independent studies on calcium blocker Nimodipine (NO) in the prevention and treatment of VS done by the author. The aim of the thesis is to analyse the management problems of aneurysmal SAH, and investigate factors influencing outcome in order to establish the best possible management policy. The results are discussed and related to the recent data from literature. The main factors influencing outcome were: clinical condition of the patient, the timing of admission and surgery, hypertension and hyperglycaemia on admission, presence of vasospasm and related CT appearance of a thick layer of blood or clot in subarachnoid haemorrhage (CT-Fisher 3). The systemic administration of the calcium blocker nimodipine did not reverse or prevent delayed vasospasm and caused serious adverse effects i.e. hypotension and hyperglycaemia. The results of the thesis suggest a change in management policy and timing of surgery should depend. on clinical condition of the patient on admission (Hunt & Hess grading)(HH I/II grade (HH as possible regardless of timing of admission and results of radiological investigations (CT, angiography). Early surgery (1-3 days) should be the aim of the effort including referral, transport and hospital organisation. III grade (HH surgery should be performed soon after day 10 post-SAH. Particular attention should be paid to the careful preparation and selection of patients for angiography. IV/V grade (HH in specialised units as s000n as possible, preferably neurological or neurosurgical wards, and operated on as soon as their grade improves or, in selected (by surgeon, radiologist and anaesthetist) cases by delayed surgery ( after day 10 post-SAH).
