Aneurysms in the upper chest are operated on, whereas aneurysms in the
lower chest and below the stomach may not be life threatening and are
watched carefully. Aneurysms less than 5 centimeters (about 2 inches)
rarely rupture and do not require surgery, whereas aneurysms greater than
2½ inches may rupture and require surgery.
4 types of Surgery & Procedures for Aneurysms
3. Coil Embolization or Endovascular Coiling: In this procedure, a patients vascular system is visualized using real time X-ray technology called fluoroscopic imaging and a catheter guided from the femoral artery (i.e., artery in the leg) into aneurysm in the head. Tiny platinum coils threaded through a catheter are guided to the aneurysm with the help of fluoroscopic imaging, blocking the blood flow into the aneurysm and preventing rupture. This process of endovascular filling the aneurysm is called embolization (8).
4. Microvascular Clipping: In this procedure, a section of the skull is removed and aneurysm are located, along with the feeder artery, with the help of a microscope. Once this is done, a small, metal, clothespin-like clip is placed on the aneurysms neck halting the blood supply. The clip remains in place and prevents future bleeding. In a related procedure, a similar occlusion (blocking) is done and flow of blood rerouted away from the damaged artery (6).
