Another option is endovascular coiling. This involves inserting a small tube into an artery in the leg. The tube is advanced up into the artery containing the aneurysm. Coils are then released. This causes clotting of the aneurysm and prevents blood from getting into it. #BBSAH

Over time the aneurysms weaken and can rupture. When it ruptures, the blood extravasates into the subarachnoid space. This is the space between the arachanoid membrane and the pia mater. This is why we call it a SAH.

There’s been a few cases of #intracerebral #haemorrhage (ICH) presenting to the #hospital recently. Causes of ICH include hypertension, trauma, AVM or rupture of an aneurysm. In one case I #scrubbed in for an #emergency #crantiomy and the #evacuation of #clot. Image:mayo clinic

The superficial temporal (artery A) has now been clipped. A clip has just been placed distally to stop blood flow. This prevents bleeding from the artery once it’s dissected.

The picture below is of a clipped aneurysm. It is just to demonstrate what a clipped artery looks like

An arteriovenous malformation (AVM) is a tangle of abnormal blood vessels between an artery and a vein. It is susceptible to bleeding leading to a hematoma.

Very proud of our @RlhNeurosurgery resident Tom and his talented wife Lauren for creating one of the winning BJNS art covers!
