Background Advances in diagnostic imaging technology have increased opportunities to discover unruptured intracranial aneurysms (UIA), and prior research has shown that UIA patients experience uncertainty both when making choices regarding treatment and after surgery.

Objectives The purpose of this study was to clarify the nature of the uncertainty experienced by UIA patients who elect to undergo endovascular surgery.

Methods Data from interviews with 31 subjects were synthesized with findings from previous research and then analyzed qualitatively and inductively.

Results Six categories were derived from the analysis to describe the uncertainty experienced by UIA patients who undergo intravascular surgery: Nature of the Disease, Treatment Characteristics, Information, Decision-making, Course of the Future, and Living with UIA.

Discussion The Treatment Characteristics and Decision-making categories reflect new aspects of uncertainty arising from advances in diagnostic imaging and appeared specific to patients with UIA. This suggests a need to select appropriate nursing methods adapted to the situation of each patient that can both reduce and manage their uncertainty. Developing an uncertainty scale for UIA patients based on the structural concepts clarified in this study and investigating reliability and validity of scores are topics for future research.
