ABSTRACT
Objective To summarize the clinical experience of one stage hybrid operation for aortic arch replacement and explore the indication. Methods From July,2009 to March,2010, 22 consecutive patients received one stage hybrid operation in our hybrid suite for aortic dissection or aortic aneurysm involving aortic arch. Two operative methods are used. (1)Bypass from ascending aorta to brachiocephalic arteries using midstemotomy and normothermia with antegrade aortic arch endovascular stented graft implantation. (2) Ascending aorta replacement and/or aortic valve replacement and/or coronary artery bypass grafting using midstemotomy and cardiopulmonary bypass with antegrade aortic arch endovascular stented graft implantation. Results All patients were technically successful. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleak of the stents. One patient in the first group died on sixth day after operation due to distal dissection rupture. There was one case of mediastinal lymph effusion in the second group and one case of death due to renal failure and respiratory failure 12 days after operation in the second group. The ICU stay and hospital stay were obviously shorter in hybrid open chest group than that in traditional open chest operation group(P ＜0.05). The blood product consumption and expenditure were also obviously less in hybrid open chest group than that in traditional open chest operation group (P ＜0.05). All the patients were followed up with a mean period of (14.45 ±2.33) months (range: 12 -20 months). All other patients were recovered with normal social life. CT showed neither endoleak nor translocation of the stented grafts. Faulse lumen closure rate at stented-graft segment is 100%. There was no obvious change of distal part of the dissection three months after operation except some thrombosis formation in some of the false lumen. Conclusion One stage hybrid operation for aortic arch replacement is safe and effective in shortening the duration of the operation and reducing the surgical trauma and risk of interval between procedures, shortening the hospital stay and reducing the blood product consumption compared with conventional operation with satisfactory early results. The midterm and long term results are still needed to be followed up.
ABSTRACT
Open defect of the Achilles tendon with loss of overlying skin is very difficult to treat. This condition poses problems of combating infection, providing soft-tissue cover and bridging the gap in the tendon. This has been generally managed in multi-staged procedures. Once the infection is brought under control with debridement and antibiotics, skin cover is provided by the flap. The tendon itself is reconstructed later by a conventional technique. More recently, composite free-tissue transfers repairing the skin and tendon in a single stage have been reported. We describe a simple and very reliable one-stage procedure, using a lateral supramalleolar island flap, a fascia lata autograft and a peroneus brevis tendon transfer, which helps tendon units bridge the gap in the Achilles tendon, and thin and mobile skin to cover the defect in the skin. Our patient showed good result, so we report this case with a review of the literature.
