Abstract:
A 74-year-old man developed a giant wide-necked pulmonary artery pseudoaneurysm. To prevent life-threatening haemoptysis, we performed percutaneous transcatheter coil embolization for the pulmonary artery pseudoaneurysm. To effectively isolate the pseudoaneurysm with the minimal number of coils, we used a steering microcatheter. With intentional folding using the bendable tip of the steerable microcatheter, we achieved compact coil packing for the target vessels, thus avoiding coil deviations and non-target embolization.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
