Hypoglycaemia as a result of insulin secreting tumours can be treated effectively by surgery. However pre-operative localization is desirable as the majority of these tumours are small and in 20% of the cases may be multiple. We describe a 1 cm insulinoma being localized pre-operatively by selective arterial stimulation with calcium and venous sampling for insulin. This technique is sensitive and relatively non-invasive. We believe that it is potentially very valuable in pre-operative localization of occult insulinomas.
胰岛素分泌肿瘤所致低血糖可通过手术有效治疗。然而，术前定位是可取的，因为这些肿瘤大多数都很小，并且在20%的病例中可能是多发的。我们描述了一例1厘米的胰岛素瘤，通过选择性动脉钙刺激和胰岛素静脉采样在术前得以定位。该技术敏感且相对无创。我们认为它在隐匿性胰岛素瘤的术前定位中可能非常有价值。
