Can sinus surgery cause brain abscess?

Condition analysis:
Thanks for your query.

Achromobacter is a bacteria. Achromobacter infection can spread all over the body, by the blood circulation, if not treated promptly with antibiotics to which this bacteria is sensitive to. Use of antibiotics- to which the bacteria is resistant- will not only delay recovery, but can also aggravate the infection.

Yes. It can extend to the base of the brain (and cause brain abscess) through direct extension or, spread also to the other organs of the body, through spread by blood circulation. However, since you are already on IV antibiotics, I am highly optimistic that you recover uneventfully.

The ideal course of action is to subject the bacteria to sensitivity test, which will short-list the MOST EFFECTIVE antibiotics. Use of one of them would facilitate early recovery. I am sure that your treating doctor has already sent the infected material for culture and sensitivity test.

Instructions:
Prognosis: If untreated, a brain abscess is almost always deadly. With treatment, the death rate is about 10% to 30%. The earlier treatment is received, the better.
Some people may have long-term nervous system problems after surgery.

Possible Complications
-- Brain damage
-- Meningitis that is severe and life threatening
-- Return (recurrence) of infection
-- Seizures
