### input:
I had a bypass operation an aneurysm in the right leg..... today my check-up gives a 100% flow and am now back from Acanocoumarol to Ascal the latter being OK for scubadiving (it says..). In the left leg there s a smaller aneurysm which even got smaller over the last 10months and is said to be stable (that s why I m allowed Ascal now). I would like to pick up my favo hobby again... which is scubadiving. Do you think I ll be safe doing so??? A depth restriction could be an idea?? Your reply will be much appreciated, Thx in advance, Rob Maller (The Netherlands)

### output:

Hello! Thank you for asking on Chat Doctor! I read your question carefully and understand your concern. Scuba diving is a stressful activity for your body, but besides the physical activity, it imposes a severe pressure change to your anatomical structures, increasing even more the risk of bleeding from an aneurysm rupture. Taking Pascal, may be safe for a normal situation, but may increase the risk of aneurysm rupture during scuba diving stress. There are not many studies related to scuba diving and aneurysms. Unruptured aneurysms, when in small diameters, have shown good results even when not treated with surgery (they have a low probability or bleeding, when unruptured). This is not a brain aneurysm, and I think that you can perform this activity with some restrictions regarding the depth of the diving, to avoid extreme pressure changes. (I would not recommend this activity in case of brain aneurysm, because the devastating consequences of possible intracranial hemorrhage). I recommend monitoring closely your blood pressure, before and after this activity and treat possible high blood pressure. Hope to have been of help! Greetings!
