摘　　要：目的探讨ED患者CA解剖变异及其对阴茎血流动力学的影响。方法应用CDUS检测45例ED患者阴茎CA及其解剖变异。结果单一CA伴DA分支供应同侧阴茎海绵体12条;CA分叉12条;一侧阴茎海绵体内两支CA并存8条。双侧CA间出现交通支2例。3例ED患者阴茎海绵体ICI后勃起正常,其双侧CA阴茎基底部PSV>30 cm/s,而中部PSV<30 cm/s;另外3例ED患者基底部及中部CA的PSV均<30 cm/s,但ICI后勃起良好。结论CA变异广泛存存并影响阴茎血流动力学状态,对其充分认识有助于ED性质的判定。Objective To explore the cavernosal arterial anatomic variation and its impact on penile hemodynamic status. Methods Forty-five patients with ED were examined by CDUS. The CA anatomic variation and its hemodynamic status were measured. Results Bifurcated CA in 12, a single CA with branches arose from dorsal arteries in 12, 2 cavernosal arteries in 8. Communicating branches between the bilateral CA were found in 2cases. In 3 patients, the erection of penis was normal after intra-cavernous injection vasoactive agents and the PSV of CA〉30 cm/s at the base of penis, but the PSV〈30 cm/s at the mid-shaft. The PSV of CA 〈30 cm/s at both the base and the mid-shaft of penis in another 3 patients, but the erection of their penis was well, Conclusion The anatomical variations of the CA occur widely and affect the hemodynamic status of penis. It is helpful for the evaluation of ED to learn about the type of anatomical variation of the CA and its impact on penile hemodynamics.
