Only capillaries have permeable walls; veins and arteries are not permeable.
Capillaries.
The smallest type of blood vessel is the capillary. Its walls are one cell thick and permeable, for substances to transfer out of the capillary and into the cells (and vice versa).
Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.Dilation of a blood vessel means widening of the vessel.

Aorta
Yes. It depends on the blood vessel and where it is, but yes a rupture to a blood vessel can kill you. A blood vessel is more likely to "pop" or rupture if it has an aneurysm, which is a local weakness where the blood vessel has stretched from the pressure of the blood. This is more likely to result in death if it is in a large blood vessel or in a critical location, such as the aorta or a vessel in the brain.
