Post-traumatic high-flow priapism: management by superselective transcatheter autologous clot embolization and duplex sonography-guided compression.

High-flow priapism is caused by uncontrolled arterial inflow into the penis, often from direct arterial trauma. We report a case of arterial or high-flow priapism that was treated with a combination of selective transcatheter autologous clot embolization and duplex sonography-guided compression therapy. Sonography showed a pulsatile, anechoic area at the base of the penis inside the left corpus cavernosum after blunt perineal trauma, and color Doppler examination revealed an arteriosinusoidal fistula. Autologous clot embolization was only partially successful, and 3 sessions of ultrasound-guided compression therapy were necessary to achieve complete thrombus formation in the fistulous tract, which became isoechoic a day after compression therapy.     

阴茎异常勃起15例诊疗体会

目的:提高阴茎异常勃起的诊治水平。方法:15例阴茎异常勃起患者,年龄20～66岁,平均46岁。持续勃起时间10～172h,平均28.4h。其中血管活性药物所致6例,膀胱癌转移至阴茎1例,白血病2例,有外伤史者3例,不明诱因者3例。对异常勃起分型,治疗及预后进行分析。结果:15例患者中,12例为低流量型,3例为高流量型。随访1～26个月,12例低流量型患者中,7例经阴茎海绵体根部注射间羟胺2～6mg,必要时在阴茎头及阴茎海绵体根部置9号针头灌注肝素化生理盐水对冲治愈,其中2例发生ED;2例行阴茎海绵体与阴茎头血管分流术治愈,其中1例术后出现ED。2例因白血病引起的阴茎异常勃起保守治疗后缓解,1例膀胱癌转移至阴茎,行阴茎全切。3例高流量型患者中1例行选择性阴部内动脉栓塞后治愈,未发生ED,2例行保守治疗出院,随访均出现ED。结论:详细的病史、海绵体血气分析和彩色双功能超声等检查有助于阴茎异常勃起正确及时的诊断。阴茎异常勃起如保守治疗无效,应立刻进行手术治疗。     

Clinical course linkage among different priapism subtypes: Dilemma in the management strategies

Objectives: Priapism is a rare condition whose management differs according to the etiology. We report the clinical course of three forms of priapism to assess the feasibility and safety of recent management strategies. Methods: The study included eight patients complaining of persistent erection for ≥4 h who were treated in our institution between January 1996 and July 2007. Results: Overall, we categorized 12 cases of priapism in eight patients divided as follows: five cases of ischemic priapism (IP), three of stuttering priapism (SP), and four of non‐ischemic priapism (NIP). Two of five IP patients needed a shunt procedure, which led to the subsequent erectile dysfunction. The other three were treated successfully with a corporal injection of sympathomimetic agents and subsequently suffered from SP. One of the three SP patients suffered from mimicked NIP with increased arterial blood flow during the initial treatment for IP. Four of the NIP patients including the mimicked one achieved complete detumescence, through arterial embolization in two and conservative management in two. Conclusions: Current management seems effective and safe in the short‐term. However, the long‐term outcome of the treatment for IP is still disappointing. Careful long‐term observation is needed for an appropriate management.     

藻酸双酯钠所致阴茎异常勃起发病机制的探讨

目的：分析藻酸双酯钠导致的阴茎异常勃起临床特点和发病机制。方法：分析我院收治的2例应用藻酸双酯钠后出现异常勃起患者临床表现、实验室检查及治疗。并检索文献,荟萃分析藻酸双酯钠导致的阴茎异常勃起的临床特点、治疗方法和发病机制。结果：CNKI《中国期刊全文数据库》1990年～2008年文献共报道12例静脉输注藻酸双酯钠后发生阴茎异常勃起,我院收治2例。14例均为缺血性阴茎异常勃起,我院的2例阴茎海绵体抽血检查DIC全项,D-Dimer分别为5320.73ng/mL、4752.45ng/mL。7例患者行海绵体抽血、灌洗并应用肾上腺素能药物有效,7例行阴茎头海绵体分流术。结论：静脉输注藻酸双酯钠可以导致缺血性阴茎异常勃起。输注藻酸双脂钠后患者阴茎海绵体局部血液高粘滞状态可能是其所致缺血性阴茎异常勃起的发生机制。保守治疗往往无效,应尽早行海绵体抽血、灌洗或阴茎头海绵体分流手术。     

A case of proximal partial priapism successfully treated with autologous clot embolisation

Partial priapism is a rare disorder in literature and generally described as a contusion or thrombosis of the cavernous body of the penis secondary to blunt trauma. Because of the rarity of disease, there is not much information about the treatment. Conservative management with nonsteroidal anti-inflammatory drug is often applied treatment. Here, we presented a proximal partial priapism treated successfully with autologous clot embolisation secondary to pelvic trauma.     

Secondary penile malignancies: the spectrum of presentation.

Secondary penile carcinoma is a rare disease with signs and symptoms covering a wide spectrum, from simple erythema to priapism. We report two cases of penile metastatic involvement that are illustrative of this spectrum.     

A CASE OF ARTERIAL PRIAPISM TREATED BY EMBOLIZATION

An 18-year-old unmarried man, who had shown arterial priapism caused by mild perineal trauma sustained during skate-boarding, has been successfully treated by autologous clot embolization at the common penile artery. He was able to have a normal erection and ejaculate 5 d after embolization.
