For the improvement in the clinical results of open stent-grafting, the development of a device system and prevention of spinal cord injury are important. For that reasons, we devised 2 methods for the open stent-grafting with the Matsui-Kitamura (MK) stent. First, the applicator using transesophagial echo transducer cover made insertion of the stent-graft system easy and safe. Next, to prevent ischemic spinal injury and protect major abdominal organ, blood return to lower body was established from femoral artery with occluding the stent graft by balloon. However, these procedures might need to examine whether it really contributes to the improvement in the clinical results.

Long-term results of open stent-grafting using a Matsui-Kitamura stent to treat thoracic aortic aneurysm.

Purpose: We describe a retrospective study of initial and long-term outcomes with an open stent grafting (OSG) with a Matsui-Kitamura stent for treating thoracic aortic aneurysm.
Methods: Between August 2005 and September 2013, 50 patients with aortic arch disease extending to the descending aorta underwent OSG. Circulatory arrest with total cardiopulmonary bypass and selective cerebral perfusion were used, and the aorta was transected between the brachiocephalic and left subclavian artery.

We report the initial and long-term results of open stent-grafting (OSG) applied with a Matsui-Kitamura (MK) stent in the treatment of thoracic aortic aneurysm (TAA). From August 2005 to March 2013, OSG for TAA was applied in 46 cases( male/female, 36/10, 54-86 years old, mean age 71). During deep hypothermic circulatory arrest with antegrade selective cerebral perfusion, stent graft was delivered through the transected proximal aortic arch, followed by arch replacement with a 4-branched prosthesis.

Open stent grafting is an alternative treatment for extensive thoracic aortic replacement. However, this procedure is associated with a high incidence of spinal cord injury, which has limited its application. Multiple factors have been suggested to explain the risk of spinal cord injury, including deep delivery of the stent graft, history of operation of the downstream aorta, and postoperative low blood pressure.

Objective: Our purpose was to examine the use of fully supported open stent grafting (OSG) with a Matsui-Kitamura (MK) stent for treatment of distal arch aneurysm (DAA).
Methods: Surgery was performed using a newly developed device in seven DAA patients (six men and one woman) from 58 to 86 years of age (mean, 73 years old) from August 2005 to June 2007. The aorta was transected at the arch between bracheocephalic artery and left subclavian artery under circulatory arrest with total cardiopulmonary bypass and selective cerebral perfusion; then the stent grafting (SG) system was inserted and positioned with a 14 Fr.
