Fatal carcinoid crisis after percutaneous fine-needle biopsy of hepatic metastasis: case report and literature review

Abstract

Immediately after a fine-needle aspiration biopsy (FNAB) was performed of a carcinoid liver metastasis, a patient had severe flushing, nausea, and faintness, followed by generalized seizure activity, profound hypotension, and cardiopulmonary arrest refractory to resuscitative efforts. This was considered due to massive release of vasoactive substances into the systemic circulation, caused by manipulation of the tumor at biopsy and aggravated by resuscitative efforts. Hypotensive crisis should be considered a potential, although unusual, complication of FNAB of liver metastases in patients with carcinoid syndrome. If biopsy is necessary, an intravenous access line should be established before biopsy is performed, and personnel should be prepared to administer emergency resuscitation. Medication with a somatostatin analogue before biopsy is performed is suggested. Catecholamine administration should be avoided.
