|December 20, 1976
Resumen
Una nueva prótesis de vena del cordón umbilical demuestra una permeabilidad temprana y tasas de rescate de extremidades comparables a los injertos tradicionales. Este injerto vascular ofrece un tiempo operativo y una morbilidad reducidos, con potencial para mejorar la durabilidad a largo plazo.
Área de la Ciencia:
- Cirugía vascular Cirugía vascular.
- Ciencia de los Biomateriales Ciencia de los Biomateriales.
- La Medicina Regenerativa es una Medicina Regenerativa.
Sus antecedentes:
- Las venas safenales autógenas son el estándar actual para la reconstrucción arterial.
- Los desafíos con los trasplantes automáticos incluyen disponibilidad limitada y morbilidad en el sitio del donante.
- Los injertos alternativos sintéticos o biológicos a menudo se enfrentan a problemas de permeabilidad y degradación.
Objetivo del estudio:
- Evaluar la eficacia de una prótesis de vena del cordón umbilical humano modificada para la reconstrucción arterial.
- Para comparar los primeros resultados de este nuevo injerto con los métodos establecidos.
- Evaluar los beneficios potenciales con respecto al tiempo operativo, la morbilidad y la supervivencia del injerto a largo plazo.
Principales métodos:
- Las venas del cordón umbilical se obtuvieron de cordones humanos y se procesaron utilizando el curtido con glutaraldehído.
- La prótesis modificada se utilizó para reconstrucciones de las arterias poplítea, tibial y peroneal.
- Se registraron tasas de permeabilidad temprana y de rescate de extremidades y se compararon con datos históricos.
Principales resultados:
- La prótesis de la vena del cordón umbilical logró una permeabilidad temprana y tasas de rescate de extremidades equivalentes a las venas safenas autógenas.
- Se observaron reducciones significativas en el tiempo operativo y la morbilidad del paciente.
- El injerto muestra una promesa de resistencia a la biodegradación, lo que podría mitigar las causas de fallas tardías.
Conclusiones:

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

01:25Abdominal Aorta
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:15Veins of Lower Limbs
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
