Origem da bandeira vermelha

DefiniçãoPheochromocytoma / paraganglioma surgery (adrenalectomy) is planned or imminent WITHOUT documented adequate preoperative alpha-adrenergic blockade (phenoxybenzamine or doxazosin). Adequate alpha-blockade is mandatory before surgery to prevent an intraoperative hypertensive crisis from catecholamine release during tumor manipulation (Endocrine Society 2014 PPGL guideline). This is a hard sequencing / safety gate, NOT a treatment-selection preference.

Notas

Models the narrative's hard requirement that "adequate preoperative alpha-blockade ... is MANDATORY before surgery to prevent intraoperative hypertensive crisis" as an explicit engine-visible safety gate (clinical_direction: hold) rather than free prose. Wired onto IND-PHEO-LOCALIZED-1L-ALPHA-BLOCKADE-ADRENALECTOMY via red_flags_triggering_alternative -- firing this RedFlag means surgery must be HELD, not redirected to a different regimen (the KB schema has no dedicated "required precondition" field on Indication, so red_flags_triggering_alternative is repurposed here for a hold-type gate, consistent with clinical_direction: hold already existing elsewhere in this KB for similar organ-readiness gates, e.g. RF-PDAC-BILIARY-OBSTRUCTION-CHOLANGITIS). No specific numeric duration or target BP/HR threshold is asserted -- "adequate" blockade is intentionally left as a clinical-judgment finding (preop_alpha_blockade_adequate), not an invented number, per CHARTER §8.3. draft:true pending clinical co-lead signoff (CHARTER §6.1, dev-mode-exempted).
