调查了140侧成人旋髂深动脉,66％发自髂外动脉,34％发自股动脉,平均外径2.8mm。旋髂深动脉升支为一支的占91.4％,为二支的占3.4％,不发升支的占4.3％。升支外径平均1.4mm,升支长度平均9.2cm。升支的体表投影可用下列三点连线表示;A点为股动脉起始部搏动点外侧2.4cm:B点为McBurney氏点外侧一横指;C点为肋弓与腋前线交点。 140 deep adult iliac arteries were investigated, 66% from the external iliac artery, and 34% from the femoral artery with an average external diameter of 2.8 mm. The ascending branch of the deep iliac artery accounted for 91.4% of the total, 3.4% for the second branch and 4.3% for the non-ascending branch. Ascending diameter average 1.4mm, ascending length average 9.2cm. Ascending branch of the body surface projection can be used to represent the following three points connection; A point outside the beginning of the femoral artery beating point 2.4cm: B point McBurney point outside a horizontal; C point rib arch and axillary line intersection.
