Bu raporun amacı, küçükbaş karotid arter ilgi implant Tevs güvenilir ve tekrarlanabilir prosedür sağlamaktır. Bu modelde kullanılan hayvan doğal karotid arterleri kalınlığında 0.5-0.75 mm ve dış çapı 4.5-5 mm idi. Burada anlatılan cerrahi teknik 3 aydır, amaçlanan son noktaya kadar etkili kanıtlayan kalınlığı 0,25-1 mm, dış çapı 4-5 mm ve büyük bir başarı ile uzunluğu 4 cm boyutlarında değişen geometrilerin Tevs yerleştirilmesi için başarılı olmuştur. Bu cerrahi tekniğin kul...

Tevs gelişimi için odak noktası otolog gemileri mevcut değilken otolog greft replasmanı için bir vekil sağlamak ve donör görüş morbidite sınırlamak için olmuştur. Örneğin, yılda koroner arter bypass ameliyatları sayısı ABD&#39;de 350.000 aştı ve uygun greft ideal kaynak koroner arter ve safen ven 1 inen sol internal meme arteri, sol ön kalır. Damar hastalıkları muzdarip birçok kişi otolog greft replasmanı için uygun arterler ve venler olmayabilir çünkü, Tevs gelişimi dolayısıyla yıllardır 1-6 araştırma yoğun bir alan haline gelmiştir. Yeni Tevs mühendislik ve optimizasyon kendileri gibi yoğun tartışma konusu olmamıştır Tevs implant kullanılan cerrahi teknikleri raporlama, birçok gelişmeler geçirmiş olsa. Aksine, hayvan modellerinde içine Tevs implantasyonu ile ilgili protokolleri büyük ölçüde terk edilmiştiraraştırmacılara araştırma kadar. Aşağıdaki yazının bir uçtan-uca anastomoz yaklaşımı kullanarak Tevs implant nasıl gösterir. Bu prosedür boyuna gerginlik ve in vivo izleme enstrümantasyon eklenmesini optimize, sütür tekniği stabilize, belirli bir anastomoz dikiş deseni kullanılarak optimize edilmiştir. Bu yöntem, daha önce kullanılmış olan birçok varyasyon bazı genellikle farklıdır. Ayrıca, bu işlem arteriyel kan basıncı, TEV çapı / uyum gibi parametrelerin elde ve eksplantasyonunun kadar ameliyat kadar sonra TEV aracılığıyla akış hızı açıklamaktadır. Bu biçimlenme sürecinde iken bu veri toplama TEV vazgeçilmez analizini sağlar.

surgical technique for the implantation of tissue engineered vascular grafts and subsequent in vivo monitoring

Doku mühendisliği Gemiler (Tevs) gelişmesi yeteneği ile ilerletilir büyük hayvan modelinde rutin olarak ve etkin bir şekilde implant Tevs (çapı 4-5 mm) arasındadır. TEV ve yerli karotid arterlerin TEV ve gerçek zamanlı dijital değerlendirmenin arası pozisyonel yerleştirilmesi için bir adım adım protokolü burada açıklanmıştır. In vivo izlenmesi mümkün hale akış sondaları, kateterler ve ultrasonik kristallerin implantasyonu (yeteneğine göre ameliyat sırasında implante Tevs ve yerli karotis arterler) dinamik çapı değişiklikleri kayıt. Bir kez araştırmacılar, nabız dalga hızı, güçlendirme indeksi, darbe basınçları ve uyum gibi parametrelerin elde arteriyel kan akımı desenleri, invaziv kan basıncı ve damar çapını hesaplayabilir, implante. Veri toplama deney süresi boyunca analiz için tek bir bilgisayar programı kullanılarak elde edilir. Böyle değerli veriler TEV matris yeniden görmemizi sağlar, onun resemblanyerli / sahte kontrolleri ve in vivo genel TEV performansına ce.
