Abstract
PURPOSE Endovascular therapy of erection-related arteries was shown to be a promising treatment option for patients with severe erectile dysfunction. Purpose of this study was to assess the longer-term safety and clinical success rate of endovascular revascularization of erection-related arteries with the Angiolite BTK stent in patients with arteriogenic erectile dysfunction. MATERIALS AND METHODS A total of 147 consecutive men (63.5±9.3 years) with erectile dysfunction due to 345 atherosclerotic lesions underwent endovascular revascularization. Patients received an International Index of Erectile Function (IIEF)-15 questionnaire at 30.3±7.2 months (follow-up [FU] period no less than 18 months) after stenting. An improvement by 4 points in the erectile function domain consisting of 6 questions (IIEF-6) was defined as minimal clinically important difference (MCID). RESULTS Technical success was achieved in 99% of lesions. One major adverse event occurred after endovascular revascularization. Sixty-eight (46%) patients completed their latest FU at least 18 months following the last intervention. Minimal clinically important difference was achieved in 54% (37/68) of patients. CONCLUSIONS In patients with arteriogenic erectile dysfunction not responding to phosphodiesterase-5-inhibitors (PDE-5-Is), endovascular therapy with a novel thin-strut sirolimus-eluting stent is a safe and effective treatment option during short- and longer-term FU. CLINICAL IMPACT Patients with severe erectile dysfunction profit greatly from endovascular therapy of erection-related arteries. Stable clinical outcomes are seen beyond a 1-year timeframe. It is proven that, the drug-eluting stent therapy for atherosclerotic ED in patients who have not responded to PDE-5-I therapy is safe and effective during longer-term follow-up.

Abstract
Erectile dysfunction (ED) is the inability to get and maintain an adequate penile erection for satisfactory sexual intercourse. Due to its negative impacts on men's life quality and increase during aging (40% of men between 40 and 70 years), ED has always attracted researchers of different disciplines, from urology, andrology and neuropharmacology to regenerative medicine, and vascular and prosthesis implant surgery. Locally and/or centrally acting drugs are used to treat ED, e.g., phosphodiesterase 5 inhibitors (first in the list) given orally, and phentolamine, prostaglandin E1 and papaverine injected intracavernously. Preclinical data also show that dopamine D4 receptor agonists, oxytocin and α-MSH analogues may have a role in ED treatment. However, since pro-erectile drugs are given on demand and are not always efficacious, new strategies are being tested for long lasting cures of ED. These include regenerative therapies, e.g., stem cells, plasma-enriched platelets and extracorporeal shock wave treatments to cure damaged erectile tissues. Although fascinating, these therapies are laborious, expensive and not easily reproducible. This leaves old vacuum erection devices and penile prostheses as the only way to get an artificial erection and sexual intercourse with intractable ED, with penile prosthesis used only by accurately selected patients.

Abstract
OBJECTIVES To explore the value of dual-energy computed tomography (DE-CT) angiography in diagnosis of arteriogenic erectile dysfunction (ED) patients and feasibility of new scanning area that excludes the testis. MATERIALS AND METHODS Ninety-three patients suspected of suffering arterial ED and 40 health volunteers underwent penile duplex Doppler ultrasound and DE-CT angiography (DE-CTA). The scanning range of DE-CTA covered whole arterial system of pelvis and testis was excluded. Two blinded investigators independently evaluated the arterial system that supplies the penis. RESULTS Finally, 1596 segments were evaluated and 470 segments were judged to be abnormal. The distribution was: 2 (0.4%) in common iliac artery, 7 (1.5%) in internal iliac artery, 82 (17.5%) in internal pudendal artery, 89 (18.9%) in penile artery, 120 (25.5%) in dorsal artery, and 170 (36.2%) in cavernosal artery. The specificity, sensitivity, positive predictive value, and negative predictive value of DE-CTA in diagnostic were 86.02%, 87.50%, 94.12%, and 72.92%. Besides, the new scan area allowed for effective evaluation of the arteries while excluding the testis. CONCLUSION DE-CTA can provide unbiased, safe evaluation of the vascular status of the penile bed in patients with ED.

The flow index provides a comprehensive assessment of erectile dysfunction by combining blood flow velocity and vascular diameter. Sci Rep 2022; 12:16099. [PMID: 36167958 PMCID: PMC9515177 DOI: 10.1038/s41598-022-19364-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 08/29/2022] [Indexed: 11/25/2022] Open
Abstract
Dynamic duplex sonography (DUS) is not comprehensive in the evaluation of arteriogenic erectile dysfunction (ED). We introduced a new parameter, the flow index (FI), into the assessment of arteriogenic ED. A retrospective review of a prospective database was conducted. Patients undergoing DUS and pelvic computed tomography angiography for the evaluation of ED were included. The FI was calculated from peak systolic velocity (PSV) and the percentages of pelvic arterial (PLA) stenosis. Correlations between PSV, PLA stenosis, the FI, and erectile function were calculated. Eighty-three patients were included. Compared with PSV, the FI had better correlations with the erection hardness score (EHS) (rs = 0.405, P < 0.001 for FI; rs = 0.294, P = 0.007 for PSV). For EHS < 3, the areas under the ROC curve of FI and PSV were 0.759 and 0.700, respectively. In patients with normal DUS but EHS < 3, PLA stenosis was more severe (62.5% vs. 10.0%, P = 0.015), and the FI was lower (8.35 vs. 57.78, P = 0.006), while PSV was not different. The FI is better than PSV in the evaluation of arteriogenic ED. On the other hand, assessment of the pelvic arterial system should be included in the evaluation of ED.

Abstract
Background Angioplasty and stenting have emerged as endovascular treatment options for arteriogenic erectile dysfunction over the past few years. Considerable anatomical variation of the erection related pelvic arteries can be challenging during these procedures, leading to time-consuming repetitive super-selective angiograms for navigation. Technique We report a novel technique of using C-arm Cone-Beam CT and vessel navigation software to facilitate super-selective catheterization. Conclusion Cone-Beam CT-guided navigation for vascular assessment of arteriogenic ED is an optional approach compared to exclusive angiographic assessment. Compared to CT angiography, C-arm Cone-Beam CT offers benefits regarding usage of contrast media and radiation exposure. It has the advantage to combine imaging with endovascular procedures in a single session, reduces time to target navigation in complex pelvic arteries anatomy and may increase therapy safety in endovascular treatment of ED.

Abstract
Background Erectile dysfunction (ED) is a prevalent health problem that seriously impacts men's quality of life. The potential treatment of ED by percutaneous approach has emerged with valid angiographic results and a significant improvement in symptoms and quality of life. In addition, cell-based regenerative therapies aiming at enhancing neovascularization have been successfully performed with peripheral blood mononuclear cells (PBMNCs) in diabetic patients affected by critical limb ischaemia. Case summary We report a case of a young insulin dependent (ID) diabetic patients who suffered of severe vasculogenic erectile dysfunction associated with a poor response for more than 1 year to oral phosphodiesterase-5 inhibitors (PDE5i) and intracavernous (IC) phosphodiesterase type 1 (PDE1) therapy. At selective angiography of the pelvic district, a severe atherosclerotic disease of the internal iliac and pudendal artery was evident with absence of distal vascularization of the cavernous bodies. The patient was treated by mechanical revascularization with drug-coated balloon and drug-eluting stent placement associated with IC injection of autologous PBMNCs. Immediate and 1-year clinical and angiographic follow-up are described. Discussion Percutaneous revascularization with drug-coated balloon and drug-eluting stent associated with IC autologous PBMNCs cells injection is a safe and effective procedure to restore normal erectile function in diabetic patients affected by severe vasculogenic ED not responding to conventional oral drug therapies.

Abstract
BACKGROUND Erectile dysfunction (ED) is a major health problem that affects a significant proportion of the general population, and its prevalence is even higher in patients with CV risk factors and/or disease. ED and cardiovascular (CV) disease share several common pathophysiological mechanisms, and thus, the potential role of ED as a predictor of CV events has emerged as a significant research aspect. OBJECTIVE The purpose of this review is to present and critically discuss data assessing the relation between ED and CV disease and the potential predictive value of ED for CV events. METHODS A comprehensive review of the literature has been performed to identify studies evaluating the association between ED and CV disease. RESULTS Several cross-sectional and prospective studies have examined the association between ED and CV disease and found an increased prevalence of ED in patients with CV disease. ED was shown to independently predict future CV events. Importantly, ED was found to precede the development of overt coronary artery disease (CAD) by 3 to 5 years, offering a "time window" to properly manage these patients before the clinical manifestation of CAD. Phosphodiesterase type 5 inhibitors are the first-line treatment option for ED and were shown to be safe in terms of CV events in patients with and without CV disease. CONCLUSION Accumulating evidence supports a strong predictive role of ED for CV events. Early identification of ED could allow for the optimal management of these patients to reduce the risk for a CV event to occur.

Abstract
BACKGROUND Arteriogenic erectile dysfunction is a common disease oftentimes not satisfactory treatable with medical therapy. AIM To assess the safety and clinical success rate of endovascular revascularization of erection-related arteries with the angiolite BTK stent in patients with arteriogenic erectile dysfunction. METHODS A total of 100 consecutive men (61.8 ± 10 years) with atherosclerotic lesions in erection-related arteries agreed to participate and were included into a single-center all-comers registry. Endovascular therapy with angiolite BTK drug-eluting stents was performed on a total of 211 lesions. Patients received a baseline International Index of Erectile Function (IIEF)-15 questionnaire at first presentation and 3 and 12 months after stenting. An improvement by 4 points in the erectile function domain consisting of 6 questions (IIEF-6) was defined as minimal clinically important difference. A total of 24 patients with 52 stented arterial lesions underwent angiographic follow-up of the initially treated arterial side during secondary revascularization of the contralateral side (angiographic sub-study). OUTCOME Clinical improvement of erections in 100 patients undergoing endovascular revascularization of erection-related arteries. RESULTS No major adverse events occurred during endovascular revascularization or within 30 days thereafter. Technical success was achieved in all lesions and procedural success in all patients. At 1 year, 55 of 97 patients (56.7%) improved by at least 4 points in IIEF-6 score and thus achieved a clinically relevant improvement of erectile function.In the angiographic sub-study, arterial patency and binary restenosis were observed in 46 of 52 (88.5%) and in 8 of 52 (15.4%), respectively, after a mean follow-up of 9.6 ± 5.8 months. CLINICAL IMPLICATIONS In patients with arteriogenic erectile dysfunction, endovascular therapy with a novel thin-strut sirolimus eluting stent is a safe and feasible treatment option. STRENGTHS & LIMITATIONS This real-world arterial revascularization registry included patients with a multitude of risk factors for ED, thereby representing the heterogeneity in patients in the clinical practice, which is one of its strengths but also one of its weaknesses. Another strength was the focus being laid on analyzing outcomes of patients with arteriogenic ED using only a single endovascular device. Further studies are warranted to better define subgroups of patients with impaired clinical outcomes. CONCLUSION Within the present all-comers registry, endovascular therapy of erectile dysfunction with the angiolite BTK stent was shown to be a safe and feasible treatment option resulting in clinical improvement rates comparable to earlier clinical trials although also showing that further research is warranted to define patient subgroups with particular benefits of endovascular therapy.

Abstract
The prevalence of erectile dysfunction (ED) is above 40% in both Asian and non-Asian male populations after the age of 40 years. The prevalence of ED among hypertensive patients is approximately double than that in normotensive population. Pelvic arterial insufficiency is the predominant cause of ED in men aged over 50 years. Stenosis in any segment of the iliac-pudendal-penile arterial system, which is considered an erectile-related arterial axis, could lead to ED. Pharmacotherapy with lifestyle modification is effective in alleviating sexual dysfunction, yet a substantial number of patients still develop ED. Given the established applicability of angioplasty for the entire iliac-pudendal-penile arterial system, penile duplex ultrasound, and pelvic computed tomography angiography could be considered as the routine screening tools in ED patients with poor response to phosphodiesterase-5 inhibitors. Endovascular therapy for pelvic arterial insufficiency-related ED has been shown to be a safe and effective treatment option in patients who have anatomically suitable vessels and functionally significant stenoses. Clinical improvement was achieved in over 60% of patients at one year following pelvic angioplasty in the PERFECT registry from Taiwan. A 30%-40% restenosis rate in distal internal pudendal and penile arteries remains a hurdle. Angioplasty for pelvic arterial occlusive disease could be considered as a viable approach to arteriogenic ED.

Abstract
Erectile dysfunction (ED) is defined as the inability to attain or maintain penile erection sufficient for successful sexual intercourse. ED carries a notable influence on quality of life, with significant implications for family and social relationships. Because atherosclerosis of penile arteries represents one of the most frequent causes of ED, patients presenting with it should always be investigated for potential coexistent coronary or peripheral disease. Up to 75% of patients with ED have a stenosis of the iliac-pudendal-penile arteries, supplying perfusion of the male genital organ. Recently the potential treatment of this pathological condition by percutaneous approaches has emerged with good angiographic results and with a significant improvement in symptoms and quality of life. This review will focus on the normal anatomy and physiology of erection, the pathophysiology of ED, the relation between ED and cardiovascular diseases and, lastly, on new treatment modalities aimed at restoration of normal erectile function.

Abstract
PURPOSE To report the 1-year outcomes of a single-center, all-comers registry aimed to assess effectiveness and safety of endovascular revascularization for atherosclerotic erectile dysfunction (ED) in an unselected patient cohort. MATERIALS AND METHODS Between April 2016 and October 2017, 50 consecutive patients (mean age 59.6±10.3 years) underwent endovascular revascularization for ED owing to >50% stenosis in 82 erection-related arteries. Patients were treated by means of standard balloon angioplasty (16%), drug-coated balloon angioplasty (27%), or drug-eluting stent (55%) implantation. The primary feasibility outcome measure was the incidence of a minimum clinically relevant improvement of ≥4 in the 6-question International Index of Erectile Function Questionnaire (IIEF-6) score at 12 months. Clinical effectiveness was improvement in erectile function as quantified in the mean difference (MD) of the IIEF-15 score at 3 and 12 months as well as the mean changes in IIEF-15 questions 3 and 4. RESULTS Procedure success was achieved in 49 (98%) of 50 patients. At 12 months, 30 (65%) of 46 patients achieved a minimum clinically relevant improvement in the IIEF-6 score. The overall IIEF-15 score, as well as scores for questions 3 and 4, improved in 32 (65%) of 49 patients, 28 (57%) of 49 patients, and 29 (60%) of 48 patients, respectively. Change in the overall IIEF-15 score at 12 months was consistent among subgroups, except for elderly patients [MD -5.0 (95% CI -9.7 to -0.2), p=0.041] and those with hypertension [MD -11.0 (95% CI -20.5 to -1.5), p=0.025], who showed less improvement. CONCLUSION Endovascular revascularization was safe and efficacious in the majority of ED patients through 1 year.

J Plast Reconstr Aesthet Surg 2018; 72:532-538. [PMID: 30765240 DOI: 10.1016/j.bjps.2018.12.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Revised: 11/10/2018] [Accepted: 12/09/2018] [Indexed: 01/17/2023]
Abstract
Erectile dysfunction (ED) is one of the most common causes of morbidity in male patients, with a prevalence of 50-60% in men aged 40-70 years. EDs may be caused by physical or psychological trauma, the former of which may be treatable through surgical intervention. Physical trauma may be further categorized as vasculogenic, neurogenic, or idiopathic in nature. Although many patients do not respond well to nonsurgical treatment options, few opt for surgical intervention. This is likely due to the difficulty of the procedures, as well as relatively low historical success rates. As such, a systematic review of the literature was performed to identify novel surgical interventions for ED. A total of 19 manuscripts were included in this review, representing data of three minimally invasive approaches to ED treatment and seven novel surgical techniques. The data revealed compelling evidence in support of microsurgical treatments for ED - namely, microvascular arterial bypass penile revascularization surgery (MABS) and cavernous nerve graft reconstruction. Nerve grafts varied, with the use of end-to-side ilioinguinal, genitofemoral, and sural grafts, all demonstrating high rates of success. Furthermore, minimally invasive botulinum toxin (BoNT-A) treatment and adipose-derived stem cell (ADSC) therapy have shown extreme promise in rat models; with BoNT-A treatment entering phase II human clinical trials this year. Many of the surgical methods investigated in this review are microsurgical interventions that demonstrate high rates of success in patients with neurogenic or vasculogenic ED. As such, microsurgeons are uniquely trained and positioned to be of value to ED treatment.

Abstract
Purpose: To evaluate the incidence of elastic recoil in patients presenting with erectile dysfunction (ED) undergoing endovascular revascularization of the pudendal or penile arteries. Methods: A consecutive series of 21 ED patients (mean age 58.3±9.3 years) undergoing minimally invasive revascularization of 31 arteries was analyzed. ED lesions included the pudendal arteries (n=27) and the penile artery (n=4). Mean lesion length was 20.6±13.9 mm. Minimal lumen diameter (MLD) measurements were assessed at baseline, immediately after balloon angioplasty, and 10 minutes thereafter. Early recoil was defined as an MLD reduction >10%. Elastic recoil with >10% lumen compromise was treated with drug-coated balloons, while severe elastic recoil (>30%) required drug-eluting stents (DES). The International Index of Erectile Function (IIEF-15) score was obtained prior to and 3 months after the procedure to obtain information on functional outcomes subsequent to angioplasty. Results: Mean MLD at baseline was 0.9±0.6 mm, which improved to 2.0±0.9 mm immediately after balloon dilation. At 10 minutes after dilation, the MLD was 1.7±1.0 mm. Elastic recoil was observed in all 31 lesions and resulted in a mean lumen compromise of 21.2%. Severe (>30%) recoil was observed in 14 arteries, which underwent DES therapy. The IIEF-15 score improved from 31.3±11.2 at baseline to 49.8±16.8 (p<0.001) at the 3-month follow-up. Conclusion: Endovascular revascularization constitutes a safe and feasible treatment modality to restore erectile function in patients with arteriogenic ED and ineffective conservative management. Early elastic recoil is very frequent subsequent to balloon dilation of small-caliber erection-related arteries. Thus, mechanical scaffolding with DES is required in a high subset of ED patients to provide favorable early angiographic and clinical results.

Abstract
Bioresorbable vascular scaffolds (BVS) have been designed to overcome long-term limitations of metallic drug-eluting stents including permanent metallic "caging" that might trigger late coronary adverse events. Here, we report for the first time a case of 72-year gentleman with previous coronary artery disease, treated by successful implantation of BVS (Absorb, Abbott Vascular) due to significant stenosis of internal pudenda artery and erectile dysfunction. After 2 years, BVS completely resorbed and there were no signs of pudendal artery restenosis on CT scan, whereas blood flow and sexual function improved.

Abstract
INTRODUCTION The field of sexual medicine is continuously advancing, with novel outcomes reported on a regular basis. Given the rapid evolution, updated guidelines are essential to inform practicing clinicians on best practices. AIM To summarize the current literature and provide clinical guidelines on penile traction therapy, vacuum erection devices, and penile revascularization. METHODS A consensus panel was held with leading sexual medicine experts during the 2015 International Consultation on Sexual Medicine (ICSM). Relevant literature was reviewed and graded based on Oxford criteria to develop evidence-based guideline and consensus statements. MAIN OUTCOME MEASURES The development of clinically relevant guidelines. RESULTS Penile traction therapy is a viable therapy to modestly improve penile length as a primary therapy, before penile prosthesis placement in men with decreased penile length or after surgery for Peyronie's disease. It also might have a role in the acute phase of Peyronie's disease but has inconsistent outcomes in the long-term phase. Vacuum erection devices are effective in creating an erection satisfactory for intercourse, even in difficult-to-treat populations. They also might be used in the post-prostatectomy setting to maintain penile length but have insufficient evidence as a penile rehabilitation therapy. For vasculogenic erectile dysfunction, men with suspected arterial insufficiency can be evaluated with penile Duplex Doppler ultrasonography and confirmatory angiography. Penile revascularization procedures have consistently demonstrated benefits in very select patient populations; however, inadequate data exists to suggest the superiority of one technique. Men with vascular risk factors are likely poor candidates for penile revascularization, although veno-occlusive dysfunction and age are less significant. Therapies for treating primary veno-occlusive dysfunction are not recommended and should be reserved for clinical trials. CONCLUSIONS Since the prior ICSM meeting, multiple developments have occurred in external mechanical devices and penile revascularization for the treatment of erectile and sexual dysfunction. Sexual medicine clinicians are encouraged to review and incorporate recommendations as applicable to their scope of practice.

Abstract
PURPOSE To assess the angiographic and clinical outcomes in patients with erectile dysfunction and isolated penile artery stenoses treated by balloon angioplasty. METHODS In this prospective study, 22 patients (mean age 61.0±7.6 years, range 50-79) with erectile dysfunction and 34 isolated penile artery stenoses (mean 74.9%±9.1%) were enrolled and underwent balloon angioplasty. The mean International Index for Erectile Function-5 (IIEF-5) score at baseline was 10.3±4.5. The mean lesion length was 11.1±9.0 mm (mean reference vessel diameter 1.7±0.4 mm). The primary endpoint was in-segment restenosis ≥50% by pelvic computed tomography angiography (CTA) at 8 months. The 1-year sustained clinical success (IIEF-5 score ≥22 or a ≥4-point change in the IIEF-5 score and no later decline by ≥4) was the secondary outcome measure. RESULTS Procedural success was achieved in 31 (91%) of 34 stenotic lesions; there was 1 flow-limiting dissection and 2 arteries with >30% residual stenosis. At 8 months, 14 of 34 lesions in 13 of 22 patients had CTA-documented binary restenosis. At 1 year, sustained clinical success was achieved in 11 of 22 patients. Of the 9 patients not developing binary restenosis, 8 achieved sustained clinical success. CONCLUSION Our findings establish the safety and efficacy of penile artery angioplasty for patients with erectile dysfunction and isolated penile artery stenoses. They also highlight the unmet need for a more enduring treatment strategy for penile artery stenotic disease.

Abstract
The treatment of erectile dysfunction (ED) has been a fascination involving multiple medical specialities over the past century with urologic, cardiac and surgical experts all contributing knowledge toward this multifactorial disease. With the well-described association between ED and cardiovascular disease, angiography has been utilized to identify vasculogenic impotence. Given the success of endovascular drug-eluting stent (DES) placement for the treatment of coronary artery disease, there has been interest in using this same technology for the treatment of vasculogenic ED. For men with inflow stenosis, DES placement to bypass arterial lesions has recently been reported with a high technical success rate. Comparatively, endovascular embolization as an approach to correct veno-occlusive dysfunction has produced astonishing procedural success rates as well. However, after a thorough literature review, arterial intervention is only recommended for younger patients with isolated vascular injuries, typically from previous traumatic experiences. Short-term functional outcomes are less than optimal with long-term results yet to be determined. In conclusion, the hope for a minimally invasive approach to ED persists but additional investigation is required prior to universal endorsement.

Abstract
Purpose: To determine the specific lesion pattern of supplying arteries in patients with cardiovascular risk factors suffering from treatment-refractory erectile dysfunction (ED). Methods: From May 2012 to August 2013, 26 men (median age 55 years) poorly responsive to phosphodiesterase-5 inhibitor therapy were evaluated for a possible vascular cause for their ED. The men were examined with penile duplex sonography and digital subtraction angiography (DSA). Arterial lesions in the common and internal iliac arteries and the internal pudendal arteries considered amenable to endovascular therapy were treated with angioplasty ± stents. Retrospectively, 2 blinded investigators independently evaluated the DSA images and categorized the vascular patterns of the erection-related arteries as normal, macroangiopathy (occlusive lesions of the internal pudendal arteries), or microangiopathy (smaller caliber arteries distal to the internal pudendal circulation with no distal arterial reconstitution). Results: Seventeen macroangiopathic lesions were successfully treated by angioplasty in 11 patients. The treated arterial lesions were mainly located in the internal (n=10) and common iliac arteries (n=2), whereas the internal pudendal artery were involved in 5 cases. Microangiopathic lesions lacking distal reconstitution were present in 7 patients, and the remaining 8 patients had normal vessels supplying the penis. Patients with macroangiopathy undergoing angioplasty had a higher prevalence of peripheral artery disease (63.6% vs 6.7%, p=0.003). Conclusion: In this preliminary series of ED patients with cardiovascular risk factors and pathologic duplex sonographic flow parameters, roughly 40% exhibited arterial lesions amenable to endovascular revascularization. In the patients with macroangiopathy, vessels upstream of the internal pudendal artery were most commonly affected. More studies are warranted to define the role of endovascular procedures in this ED subpopulation.
