Hereditary Hemorrhagic Telangiectasia (HHT) may be associated with a variety of emergencies.
The most common complication is bleeding which may arise from:
(1) cerebral arteriovenous malformations
(2) pulmonary arteriovenous malformation
(3) hepatic arteriovenous malformations
(4) telangiectasias
(5) arteriovenous malformations in other organs
In addition, HHT may be associated with:
(1) vascular shunting or vasculr steal.
(2) ischemia
(3) thromboembolic events
Emergencies may arise due to:
(1) massive nosebleeds (epistaxis)
(2) hematemesis
(3) melena
(4) hematochezia
(5) hemothorax
(6) hemoptysis
(7) TIA, stroke, hemorrhagic stroke
(8) brain abscess
(9) ischemic hepatopathy with hepatic disintegration
(10) thromboembolic event
(11) acute heart failure
(12) sudden visual loss
(13) hematuria
(14) uterine bleeding
(15) ischemic cholangiopathy
(16) portosystemic encephalopathy
