Smaller incisions, less pain, quicker recovery — Endovascular Treatment
Coronary blood vessels are not the only ones that become narrowed or blocked. For example, buildups of plaque that adversely affect circulation can also happen in arteries in the legs. If not treated, gangrene may set in, and in the worst case, amputation may be required. In the past, peripheral arterial disease was treated with bypass surgery, which used other blood vessels to secure blood supply. Now, there is a new alternative. With the same procedures as those used in coronary arteries, balloon catheters and stents can widen affected arteries and improve circulation. Around the world, patients all hope the same thing: less pain, minimal invasive treatment, and swifter return to daily life.
Endovascular treatment, which is easier on patients, now extends to the entire body
The aging of populations and the prevalence of lifestyle-related diseases have caused significant increases in neuroendovascular and peripheral arterial diseases as well as in coronary diseases. Endovascular treatment, which relies on therapeutic intervention catheters inserted through wrist or thigh vessels can be accomplished via minimal incisions, a process much easier on patients than open surgery. Patients are also pleased that the scars of intravascular treatment are virtually invisible. With our long history of products for coronary intervention treatment, Terumo is ready to support vascular treatment in the rest of the body as well, helping patients return to life as quickly as possible.
Peripheral stent that conforms to the movement of legs
The peripheral stent produced by Terumo not only keeps the blood vessels open, bends and twists with the movement of the patient’s legs as well.
Neuroendovascular coil for the treatment of cerebral aneurysms
In neuroendovascular therapy, more and more aneurysms are being treated with endovascular coiling, which fills the aneurysm with platinum coils to prevent blood from entering it. Aneurysms located deep within the brain, which are difficult to treat surgically, can be treated with coiling. Hydrogel coils of MicroVention, Inc., a company of Terumo group, have gel in the spaces between the individual coils, which improves the impermeability of the packed coils within the aneurysm. Endovascular coiling now accounts for fully 50% of neuroendovascular aneurysm treatments in Western countries. Some 30% of cases in Japan are treated by coiling, a share that continues to increase.
We had the opportunity in our Vascular Center Berlin to implant the first peripheral stent of Terumo a couple of years ago.
Afterwards we achieved more experience, especially comparing normal ballooning with bail-out stenting with primary stenting, using Terumo’s peripheral stent in the superficial femoral and popliteal arteries.
Results using this flexible rapid-exchange stent with high radial force were excellent and it became our work horse for daily practice.
