Main risk factors are age, cardiovascular disease, smoking, depression and diabetes mellitus. Therefore, ED might indicate an early manifestation of general disorders and should thus be an inherent part in raising a medical history.</p></span><span id="cesec20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle20">CASE REPORT</span><p id="para20" class="elsevierStylePara elsevierViewall">In May 2006, a 37-year-old man presented in our outpatient clinic with light ED that had prevailed since puberty. Penetration was possible only in a standing position, generally reaching nearly full erection. Lowering the upper part of the body caused the erection to become weaker and sexual intercourse was hardly possible. Self-administered phosphodiesterase type 5 inhibitors did not show any effect on the position dependence. The patient was distressed by this situation.</p><p id="para30" class="elsevierStylePara elsevierViewall">In other respects, he was healthy and there was no evidence of psychosomatic etiology. The only abnormal finding in routine diagnostic investigation for ED consisted of congenital penoscrotal cavernous hemangioma (<a class="elsevierStyleCrossRef" href="#fig1">Figure 1a</a>). As a vascular cause of the symptom was suspected, we performed MRI angiography after intracavernosal application of 10 μg alprostadil (<a class="elsevierStyleCrossRef" href="#fig1">Figure 1b</a>): a substantial arteriovenous malformation showed symmetrical draining towards the internal iliac veins. As a result, the penile arteries appeared rarefied.</p><elsevierMultimedia ident="fig1"></elsevierMultimedia><p id="para40" class="elsevierStylePara elsevierViewall">A surgical approach was judged not promising and too risky. Therefore, we recommended selective percutaneous retrograde venoocclusive therapy,<a class="elsevierStyleCrossRef" href="#bib2">2</a> which was performed successfully in two sessions (<a class="elsevierStyleCrossRef" href="#fig1">Figure 1c</a>). We assessed the International Index of Erectile Function (IIEF)<a class="elsevierStyleCrossRef" href="#bib3">3</a> and found a score of 18 at baseline, 21 at 3-months' follow-up and 18 at 24-months' follow-up (no ED at IIEF score >21). To objectify the functional changes we measured penis rigidity using RigiScan Plus® at baseline and 3-months' follow-up:<a class="elsevierStyleCrossRef" href="#bib4">4</a> after intracavernosal application of 10 μg alprostadil and achieving maximal erection, data were acquired continuously while the patient alternated between standing and lying positions with a minimum episode duration of 5 minutes. As rigidity on the penile tip has proved to be the best overall predictor of erectile dysfunction,<a class="elsevierStyleCrossRef" href="#bib4">4</a> we used this parameter as our main outcome criterion. Values for all useable lying and standing intervals were compared by applying a paired samples t-test (<a class="elsevierStyleCrossRef" href="#fig2">Figure 2</a>); p<0.05 was considered significant. At baseline, mean tip rigidity values differed significantly (p = 0.038) while at 3-months' follow-up differences were no longer significant (p = 0.676). Although observed differences were small and there were no data on long-term test-retest reliability for Rigiscan® measurements, these results are consistent with the patient's subjective view. Rigidity had improved, especially in the distal part of the penis and was less dependent on body position. At 24-months' follow-up, the patient rated therapeutic success to be very satisfying, although the IIEF score had returned to the baseline score of 18.</p><elsevierMultimedia ident="fig2"></elsevierMultimedia></span><span id="cesec30" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle30">DISCUSSION</span><p id="para50" class="elsevierStylePara elsevierViewall">We describe the diagnostic work-up and treatment outcome in a young patient with position-dependent ED due to an arteriovenous malformation. Hemangiomas are rarely found in the genitourinary tract<a class="elsevierStyleCrossRefs" href="#bib5">5–12</a> and cause ED in only a few cases, dependent on their hemodynamic properties.<a class="elsevierStyleCrossRef" href="#bib5">5</a> In this case, the congenital arteriovenous malformation drains arterious inflow directly to the internal iliac veins. Therefore, part of the arterial blood supply bypasses the corpora cavernosa and leads to a special form of venous leakage. However, the extent of the venous leakage and hence the erection rigidity depend on the intra-abdominal pressure, which alters with body position. For objectifying this anamnestic information and monitoring treatment outcome the Rigiscan® device proved helpful. It is one of the diagnostic measures recommended when cases remain ambiguous after basic investigation.<a class="elsevierStyleCrossRef" href="#bib1">1</a></p><p id="para60" class="elsevierStylePara elsevierViewall">Vascular conditions are the most common organic cause of ED.<a class="elsevierStyleCrossRef" href="#bib13">13</a> The vast majority of cases in this group result from metabolic changes, increasing with age owing to cardiovascular disease and diabetes mellitus. By far less common, but more important in younger men with ED are macroscopic arterial or venous pathologies, because once diagnosed, some of them can be treated causally. Patients with a history of pelvic or perineal trauma causing arteriogenic ED can benefit from vascular surgery with a 60-70% long-term success rate.<a class="elsevierStyleCrossRefs" href="#bib14">14,15</a> However, the results are entirely different concerning surgery for venous leakage. The various types of venous resection show discouraging long-term results and have therefore been abandoned in general.<a class="elsevierStyleCrossRef" href="#bib14">14</a> Only very occasionally, more durable improvements have been reported in highly selected patients.<a class="elsevierStyleCrossRef" href="#bib16">16</a> Because surgical treatment outcomes are limited, minimal invasive approaches like percutaneous embolization seem justified. This holds especially true as otherwise a penile prosthesis is the final option.<a class="elsevierStyleCrossRef" href="#bib17">17</a> After interventional venoablative treatment initial response rates are around 70-80%, while lasting treatment success is found in <30%. The latter is mainly due to venous collateralisation.<a class="elsevierStyleCrossRefs" href="#bib2">2,18,19</a></p><p id="para70" class="elsevierStylePara elsevierViewall">Limited long-term success has also been found in the reported case. Nevertheless, the subjective view of ED is not necessarily linked to objective measurements and our patient still feels satisfied.</p><p id="para80" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleBold">Ethics committee approval:</span> We performed all actions according to the “Declaration of Helsinki” in its latest version and respected usual data protection requirements. Ethics committee approval was not needed because the routine treatment of an individual patient is described. The patient is aware of the planned publication of his case. He agreed and documented his decision by signing a consent form after reading the manuscript including figures.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:4 [ 0 => array:2 [ "identificador" => "cesec10" "titulo" => "INTRODUCTION" ] 1 => array:2 [ "identificador" => "cesec20" "titulo" => "CASE REPORT" ] 2 => array:2 [ "identificador" => "cesec30" "titulo" => "DISCUSSION" ] 3 => array:1 [ "titulo" => "REFERENCES" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "multimedia" => array:2 [ 0 => array:7 [ "identificador" => "fig1" "etiqueta" => "Figure 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 188 "Ancho" => 661 "Tamanyo" => 21522 ] ] "descripcion" => array:1 [ "en" => "<p id="spara10" class="elsevierStyleSimplePara elsevierViewall">a, Penoscrotal hemangioma; b, 3D-view of MRI-angiography showing venous leakage*; c, state after radiologic intervention.</p>" ] ] 1 => array:7 [ "identificador" => "fig2" "etiqueta" => "Figure 2" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr2.jpeg" "Alto" => 308 "Ancho" => 425 "Tamanyo" => 21069 ] ] "descripcion" => array:1 [ "en" => "<p id="spara20" class="elsevierStyleSimplePara elsevierViewall">Penis mean tip rigidity at baseline and at 3-months' follow-up in lying (left bars) and standing (right bars) position.
