About this study

Delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH) was long thought to be caused by subarachnoid blood-induced vasospasm. Experimental and clinical evidence suggest activation of several pathophysiological pathways, affecting the cerebral microcirculation. Recently, lower in-hospital mortality and less non-home discharge was reported in patients treated with therapeutic low-molecular weight heparin (LMWH), compared to patients with standard, prophylactic LMWH, pointing towards a potential benefit of higher doses of LMWH in the acute course after aSAH. Treatment with therapeutic LMWH might improve clinical outcome in endovascularly treated aSAH patients. The primary objective is to evaluate whether aSAH patients treated with therapeutic LMWH have a lower 30-day mortality rate compared to patients treated with prophylactic LMWH. Secondary objectives are to evaluate whether there are significant differences between patients treated with therapeutic and prophylactic LMWH in development of DCI, (hemorrhagic) complications during admission, hydrocephalus, non-home discharge location, quality of life, clinical outcome and cognitive functioning at three and six months, total health care costs. A single center, prospective, phase II randomized clinical trial in aneurysmal SAH patients ≥18 years old, in whom the causative aneurysm is treated with endovascular coiling less than 72 hours after initial SAH. Patients are randomized into 2 groups: (1) Therape…
