在30具6～9月龄胎尸上,观测了胸腺的动脉来源、静脉回流和胸腺的体积。动脉为多源性,但以胸廓内动脉的胸腺支最为恒定。静脉多不与动脉相伴行。本文依据胸腺形态、体积和动脉来源,提出以胎儿作供体,设计单侧叶、双侧叶或单侧叶部分吻合血管移植,并就取材方法、供吻合的血管蒂进行了讨论。 Thirty-six 6-to-9-month-old fetal corpses examined the origin of thymus arteries, venous return, and thymus volume. Artery is multi-source, but the thymus branch of the thoracic artery is the most constant. More veins and arterial accompanying line. Based on the thymus morphology, volume and arterial origin, this paper presents a fetus as the donor, design of unilateral, bilateral or unilateral partial anastomosis of vascular graft, and the method of collection for the anastomosis of vascular pedicle were discussed.
