[Utility of arteriography with selective arterial calcium injection for the diagnosis of insulinoma].
BACKGROUND
Common preoperative imaging techniques for the diagnosis of insulinomas do not lead to an effective localization in 40% cases. We present here our experience with arteriography followed by selective arterial calcium injection (AACI).


METHODS
Retrospective review of AACIs and other techniques performed in patients with endogenous hyperinsulinism.


RESULTS
AACI either localized the tumor or at least conditional its surgical resection in nine out of 11 cases. In 2 out of 11 patients, the test yielded a negative result (factitious hypoglycemia). Only 4 tumors were identified by other techniques.


CONCLUSIONS
AACI is a first-choice technique for the preoperative localization of insulinomas. It may also help rule out other causes of hypoglycemia.
