药物性阴茎双功能超声在诊断双干背深静脉漏中的价值

Value of pharmacopenile duplex ultrasonography in the diagnosis of leakage of double deep dorsal veins

目的:探讨药物性阴茎双功能超声(PPDU)在双干背深静脉漏性阴茎勃起功能障碍诊断中的价值。方法:回顾性分析经手术证实为双干背深静脉漏组患者32例和单干背深静脉漏组患者40例,对比分析两组患者PPDU的诊断结果、超声图像特征、背深静脉和海绵体动脉血流动力学参数,并与阴茎海绵体造影(CG)和手术结果对照。结果:PPDU对双干背深静脉变异的诊断准确性为81.3%。双干背深静脉漏组和单干背深静脉漏组患者的超声诊断准确率分别为75.0%和92.5%,二者比较差异有统计学意义(P<0.05);单干背深静脉的内径与双干背深静脉任意一支内径比较,差异无统计学意义(P>0.05),但明显小于双干背深静脉的两支静脉内径之和(P<0.05);双干背深静脉漏组与单干背深静脉漏组患者的背深静脉流速、海绵体动脉的收缩期血流峰值速度(PSV)、舒张末期血流峰值速度(EDV)及其阻力指数(RI)比较差异均无统计学意义(P>0.05)。72例患者CG诊断双干背深静脉漏4例,其余均表现为单支背深静脉漏。结论:PPDU对双干背深静脉变异的诊断较CG更有优势,能准确诊断背深静脉漏及受累支数,可作为双干背深静脉漏首选的影像学检查方法。

Objective:To explore the value of pharmacopenile duplex ultrasonography(PPDU)in the diagnosis of leakage of double deep dorsal veins in patients with erectile dysfunction(ED).Method:A retrospective analysis of 32 patients with leakage of double deep dorsal veins and 40 patients with leakage of single deep dorsal vein was performed.The diagnosis of PPDU,ultrasonographic features,flow dynamics parameters of deep venous and cavernous arterial blood were compared between the two groups,and were compared with radiography of corpus cavernosum(CG)and surgical outcomes.Result:It was found that 81.3%of all double deep dorsal venous malformation were diagnosed accurately by PPDU.Diagnostic accuracy of ultrasound for leakage of double deep dorsal veins and leakage of single deep dorsal vein were 75.0%and 92.5%,respectively,which the difference was statistically significant(P<0.05).The diameter of the single deep dorsal vein had no significant difference compared with either of the double deep dorsal deep vein(P>0.05),but significantly less than the diameter sum of these two veins(P<0.05).There was also no significant difference in the venous flow rate and the cavernous arterial parameters(PSV,EDV or RI)between the two groups(P>0.05).Seventy-two patients with leakage of double deep dorsal veins were performed by radiography of CG,but only 4 cases with bilateral leaks were described clearly,and the rest showed leakage of single deep dorsal vein.Conclusion:PPDU is more advantageous than radiography of CG in the diagnosis of double deep dorsal veins.It can accurately diagnose the deep dorsal venous leak and the number of affected branches.It can be used as the first choice for imaging examination of double deep dorsal venous leak.
