Arteriosclerosis obliterans is an occlusive arterial disease most prominently affecting the abdominal aorta and the small- and medium-sized arteries of the lower extremities.
It is characterized by fibrosis of the tunica intima and calcification of the tunica media. Then the arteries in the body become thickened and narrowed, ultimately leading to less blood flowing through the arteries to get to the cells and muscles.
Treatment for arteriosclerosis obliterans involves both medication and surgery. The symptoms can be relived by diet, exercise , quitting smoking and drug therapy. But not only effective in relieving symptoms, but also in reducing the incidence of vascular events and death. Surgeries for arteriosclerosis obliterans include angioplasty, bypass therapy, endarterectomy and omentuml transplantatin , which can be performed depending on the location and severity of the narrow, or blocked, artery.
Angioplasty, in which a catheter is used to stretch the artery and a stent is put in place to hold the artery open. Study shows that angioplasty is encouraged because of high success rate and low complication. It is better than bypass surgery for its have minimal invasion and high patency rate.
We Trandomed can 3D print artery models with Arteriosclerosis obliteran based on patients'CT/MRI data. Surgeons can analyse the hardening artery wall from any angle virtually or physically by these models. They will reach a much more comprehensive understanding of their patient’s injuries and to determine the optimal treatment for each diagnosis. By practicing on the models before performing surgery, surgeons can decrease the chance of error and reduce the rate of complications and infections. They also can be used to show patients what exactly is wrong with their artery and what is best treatment for their situations.
