Question: Can a capillary telangiectasia affect diving?


 AGUIGUI - Sat Sep 19, 2009 4:18 pm

Recently, a neurologist detected me a capilary tellangiectasia in the brain stem. I am a marine biology student and also a diver; my question is: will it affect the capilary telangiectasia in some way if I go diving?is there some treatment for this?. A doctor friend of the family suggested me the gamma knife treatment but i'm not sure if it is the correct procedure in my case?. I also present from time to time intermittent headaches in no specific location, they almost always last 1 or 2 minutes, sometimes even seconds. These headaches always come along with a sharp/stab pain in the place where they occur. I'm worried that because of this telangiectasia i can not continue diving. If you could please help me, I would be very grateful with all of you. Thanks, in advance.

User avatar Hi,
Brain capillary telangiectasia (BCT) are usually small, solitary, benign in disposition, or found incidentally at autopsy (diffuse BCT are rarely reported, which are said to be more symptomatic).Of late,most are being diagnosed incidentally while investigating for other conditions by imaging (perhaps that is what happened in your instance).

The incidence is difficult to estimate since most of them remain clinical silent.

They are most common seein in the 4th to 8th decade.
Spontaneous hemorrhage is extremely uncommon.

Occasionally, they become symptomatic (headaches,dizziness, vertigo,visual disturbances,confusion, tinnitus etc).

As they are a comparatively recent discovery,there are not enough studies(to the best of my recollection), to base an answer to your question regarding their possible adverse effects in deep sea divers with this condition.
Best wishes!
