Question

___ can occur in the cerebral or systemic circulation due to septic embolization and localized vessel wall destruction as a complication of infective endocarditis.

___ can present as an expanding mass with focal neurologic findings or with aneurysm rupture and subarachnoid hemorrhage..

Answer 1

Septic embolization and myotic aneurysms are complications that can occur due to infective endocarditis. Septic emboli can lodge in cerebral or systemic vessels, leading to localized wall damage and formation of myotic aneurysms, which can cause neurologic symptoms or rupture.

Step-by-step explanation:

Septic embolization can occur in the cerebral or systemic circulation due to septic embolization and localized vessel wall destruction as a complication of infective endocarditis. Myotic aneurysms can present as an expanding mass with focal neurologic findings or with aneurysm rupture and subarachnoid hemorrhage.

In cases of infective endocarditis, bacteria can induce the formation of vegetations on the heart valves. These vegetations can dislodge and form septic emboli, which can travel through the bloodstream and lodge in cerebral arteries or systemic circulation. The emboli cause localized damage to the vessel walls, which may lead to the formation of mycotic aneurysms. Mycotic aneurysms can weaken the blood vessel walls, cause a mass effect that can result in focal neurologic symptoms, or rupture, which may result in a potentially life-threatening subarachnoid hemorrhage.
