Aim: We investigated retrospectively whether symptomatic vasospasm after SAH is associated with the duration of surgical exposure.
Methods: Between 2001 and 2003, 35 patients undergoing neck clipping surgery were reviewed retrospectively. The duration of surgical exposure was defined as the time from the dural incision to its closure. We compared baseline clinical data, duration of surgical exposure, intraoperative aneurysm rupture (IAR), temporary clip application and clinical outcome in patients with symptomatic vasospasm (Spasm) and without it (Nonspasm).
Results: Baseline clinical data was similar in the Spasm and Nonspasm groups. The duration of the surgical exposure was significantly greater in the Spasm group than the nonspasm group (spasm 211±68 min, nonspasm 165±47 min, P=0.02). The incidence of IAR and temporary clip application did not differ between the spasm and nonspasm groups.
Conclusion: Our retrospective analysis would raise the possibility that symptomatic vasospasm after SAH might be associated with longer surgical exposure.
