ABSTRACT
We report a 41-year-old man who presented with a ruptured dissecting aneurysm of the descending aorta. He had undergone aortic root replacement for an acute aortic dissection (Stanford type A) ; 8 months later, he had undergone total arch replacement with insertion of a frozen elephant trunk (FET) due to enlargement of the chronic dissecting aneurysm of the arch. FET-induced new entry and incomplete thrombosis occurred postoperatively. Three months after FET insertion, he developed an aortic rupture that required emergency replacement of the descending aorta. The patient tolerated the procedure well and was discharged 16 days after the operation.
ABSTRACT
Bleeding control during aortic surgery is one of the most important issue. The well-known fibrinogen-based hemostat contains the blood product, which means the potential risk of the blood-related infection. Recently, the newly-designed hemostat “Hydrofit”, which is assembled with urethane-based polymer without blood product (Matsudyte : Sanyo-chemical industry, Kyoto, Japan). Hydrofit is applicated for the hemostasis of thoracic aortic surgery. In sealing of the Hydrofit gel to the anastomosis site of aorta, water-contact initiation boosts the chemical change to the forming elastomer and adheres around anastomosis site rapidly. We experienced the extirpation of the Hydrofit which was used over 4 years ago. The patient is 42 year-old female who was operated aortic valve replacement and graft replacement of ascending aorta using a Hydrofit as a hemostat at 4 year 8 months ago due to the aortitis syndrome. Re-sternotomy and re-AVR was performed because of the prosthetic valve dehiscence due to the active aortitis syndrome. Hydrofit left around suture line without infection, and functioned very well as the elastic sealant for the long-term period.
