Results: The diameter of the metatarsal nutrient artery was 0.24~ 0.30 mm. 结果:跖骨滋养动脉的直径为0.24~0.30mm。
Methods: Radionuclide imaging was used to survey the change of the femoral or tibial blood supply after ligating nutrient artery in rabbits. 方法:采用放射性核素显像法,观察滋养动脉结扎后兔股骨或胫骨血供的变化。
The periosteum near linea aspera should not be stripped during operation on super medial femur fracture to avoid damage on superior nutrient artery. 股骨中、上段骨折手术时,应避免剥离近粗线的骨膜,以免损伤上滋养动脉。
Results: Sixty percent of the femurs had 2 nutrient arteries and 40% of them had only 1 nutrient artery. 结果:①60%股骨有上、下2条滋养动脉,40%仅有1条上滋养动脉,其中上滋养动脉为主要动脉。
The nutrient artery to fibula is relatively small and short, and all originate from the fibular artery. 腓骨滋养动脉均起自腓动脉,但起始高度则多变。腓骨滋养动脉的口径细小,行程亦短,其平均长度为1.1厘米,起始段外径平均0.9毫米;
Our results indicate that original artery of the nutrient artery, supplying the superficial branch of the radial nerve, is ideal for a free vascularized nerve graft. 观察结果表明,以来源动脉为蒂,作为桡神经浅支移植的吻接血管是可行的。
The nutrient artery of the metatarsal bone of fetus 胎儿跖骨的滋养动脉
Observation of the metatarsal nutrient artery 跖骨滋养动脉的观察
Results: Nutrient artery of the trigeminal nerve root mainly came from pontine branches of basilar artery and from branches of internal carotid. 结果:三叉神经根的动脉主要来源于基底动脉的脑桥支和颈内动脉的分支。
Methods: The origin of nutrient artery of the abducent nerve root, and neurovascular relationships were observed on 18 brain stems. 方法:选取18例脑干,观测展神经根池段的滋养动脉来源及其与邻近血管的关系。
Results: ( 1) The position and external diameter of peroneal artery, its accompanying vein and the dis-tribution of fibular nutrient artery were observed. 结果:(1)观测了腓动脉及其伴行静脉起点的位置和外径及腓骨滋养动脉的分布。
The nutrient artery of tibia from posterior tibial artery is 90%, the nutrient artery goes down through deep popliteal muscle and long flexor of digits, clinging to tibial back and sending off bone skin branch and nutrient branch. 胫骨滋养动脉来自胫后动脉占90%,滋养动脉起始后行经腘肌下部深面和趾长屈肌深面,紧贴胫骨后面,分出骨皮支和滋养支。
The blood supply of the metatarsals is derived from the nutrient artery, the periosteal arteries, the epiphyseo-metaphyseal arteries and the pseudoepiphyseal arteries. 分布于跖骨的动脉来自滋养动脉、骨膜动脉、骺-干骺动脉和假骺动脉。
Anatomical study of nutrient artery of spinal cord on the thoracic and lumbar region in canine 成年家犬胸腰段脊髓营养动脉的解剖学研究
Results The sural nerve nutrient artery has 2 to 4 branches with constant three branches and the vessel network is formed in an anastomosis way. 结果腓肠神经营养动脉2~4支,各营养动脉形成血管网相互吻合,其中三支发出较为恒定。
Objectives: To provide the anatomical basis of transplantation of pedicled pisiform bone to replace carpal bone with necrosis by observing the source of blood supply and the distribution character of nutrient arteries of pisiform, and by measuring caliber and length of every nutrient artery. 目的:观察豌豆骨的血供来源和滋养动脉的分布特点,并测量各滋养动脉的管径和长度,为以带血管蒂豌豆骨转移替代其他腕骨坏死提供解剖学依据。
The main nutrient artery of the trapezius muscle is the transverse cervical artery. Its trunk is 41.03 mm in length, and 2.31 mm in outer diameter on the average. 斜方肌的主要营养动脉是颈横动脉,其干的平均长度为41.03毫米,平均外径为2.31毫米。
It is a general practice of the orthopaedic surgeons to strip the periosteum, to ream the medullary cavity etc, which may easily cause injury of the nutrient artery of the long bones. 骨膜剥离和髓腔扩大是骨科手术中常用的操作方法,滋养动脉在手术中受到损伤时也需结扎。
