- W2070150616 abstract "Guglielmi detachable coil (GDC) embolization may be used to prevent early rebleeding after aneurysmal subarachnoid hemorrhage, but anticoagulation and induced hypertension may increase this risk. We sought to determine retrospectively the relationship between levels of induced hypertension and anticoagulation and incidence of rebleeding in GDC-treated patients.Twenty-five consecutive patients with acute (<14 days) subarachnoid hemorrhage who underwent GDC embolization were retrospectively analyzed with regard to percent obliteration of an aneurysm on postprocedure angiogram, the duration and intensity of anticoagulation, the duration and level of induced hypertension, and the frequency of thromboembolic and rebleeding complications.Complete angiographic obliteration of the aneurysm was achieved in five cases (20%). In some cases (n = 2), only the dome of the aneurysm was coiled to allow eventual surgical clipping. Heparin was given to 23 patients (92%) for an average of 6 days (range, 8 hrs to 22 days); the mean dose was 588 units/hr, and the mean partial thromboplastin time was 37 secs. Seven patients (28%) were treated with vasopressors for symptomatic vasospasm for a mean duration of 5 days (range, 8 hrs to 9 days); mean arterial blood pressure averaged 118 mm Hg, and peak systolic blood pressures ranged from 195 to 250 mm Hg. There were no episodes of aneurysm rebleeding. Three patients (12%) suffered intraoperative thromboembolic complications, which in one instance was fatal; two of these cases were associated with subtherapeutic partial thromboplastin time values.Induced hypertension (mean arterial blood pressure, 120 mm Hg) and heparinization do not appear to increase the risk of early rebleeding after GDC embolization. In a select group of patients, use of anticoagulation in the immediate perioperative period to prevent thromboembolic complications appears to be safe." @default.
