Prospective follow-up of sexual function after elective repair of abdominal aortic aneurysms using open and endovascular techniques

Sexual dysfunction after open abdominal aortic aneurysm repair: 16 years' experience in a quaternary center and literature review

Background

Open abdominal aortic aneurysm (AAA) repair can lead to sexual dysfunction (SD) in men.

Objectives

To determine the prevalence of SD following open AAA repair, explore whether surgical techniques for aortic reconstruction can have a differential impact on the occurrence of SD, and summarize current knowledge in this field.

Methods

Retrospective review of 100 patients submitted to open AAA repair between 1995 and 2010 in a quaternary center. Sexual dysfunction was assessed according to questions from the modified International Index of Erectile Function (IIEF), considering the condition before surgical repair and 3 months after surgery. The chi-square test, Fisher's exact test, and Student's t test were used for statistical analyses.

Results

100 patients were included (mean age = 66.4 years old). Normal sexual activity, no sexual activity, erectile dysfunction, and retrograde ejaculation with preserved erectile function were found in 36%, 21%, 18%, and 24% of patients, respectively. The group of patients with no sexual activity was older (mean age = 72.3 years old vs 64.5 years old, p < 0.001). Erectile dysfunction prevalence was higher in patients submitted to an aorto-bifemoral bypass (p = 0.032). Retrograde ejaculation was more frequent in patients submitted to an aorto-aortic bypass (p = 0.007).

Conclusions

Sexual function is a frequent condition intimately associated with the aortic reconstruction technique. The literature review found contradictory results regarding whether the endovascular approach is protective compared with open repair, but clearly demonstrated the importance of techniques targeting preservation of the internal iliac artery and the superior hypogastric plexus.

Analysis of Repair Type and Hypogastric Artery Antegrade Perfusion and Erectile Function Following Repair of Abdominal Aortic Aneurysms

OBJECTIVES

Published reports suggest that exclusion of antegrade hypogastric artery flow may have deleterious effects on erectile function after abdominal aortic aneurysm repair. Off-label and open surgical hybrid procedures and, more recently, purpose-built branched devices have been developed to maintain antegrade pelvic perfusion in patients undergoing endovascular repair. Maintaining antegrade perfusion may reduce a spectrum of risks, including buttock claudication, colorectal ischemia, spinal cord ischemia when patients undergo subsequent thoracic aortic procedures, as well as erectile dysfunction. This project specifically focuses on erectile function, and analyzes baseline associations and relationships of hypogastric artery exclusion on changes in erectile function following aneurysm repair.

METHODS

Male patients in the Veterans Affairs Open Versus Endovascular Repair (CSP#498; OVER) Trial had erectile function assessed pre- and postoperatively by administration of the International Index of Erectile Function-5 questionnaire. Bayesian mixed-effects regression models were created with the outcome variable (erectile function) treated as a latent variable. Primary effects of differences in erectile function between groups with and without preservation of bilateral antegrade hypogastric flow were compared.

RESULTS

876 men (442 randomized to endovascular repair) were enrolled in the trial and included in the analysis comparing treatment assignment. There is significant erectile dysfunction in elderly men with aortic aneurysm at baseline. Over five years of follow up, there is modest decrease in erectile function and the endovascular group has improved function compared to open repair (0.082; 95% credible interval 0.008 and 0.155). A fifth of patients did not have bilateral preservation of antegrade hypogastric artery perfusion, with no difference in erectile function by univariate analysis. A more detailed regression analysis was applied--and after adjustment for baseline score, age, beta blocker use, diabetes, activity level, ejection fraction, preoperative ABIs and time--preservation of both antegrade hypogastric arteries' perfusion showed transient improvement in survey scores compared to occlusion of at least one hypogastric artery at 6 months and 12 months after treatment, although this was not sustained at 60 months (score change: 0.046; 95% credible interval: -0.123, 0.215). Retesting this model in the cohort with complete data as a sensitivity analysis did not meaningfully change the conclusions.

CONCLUSIONS

In this large prospective aneurysm treatment trial with systematic measurement of erectile function with a validated instrument, endovascular repair is associated with improved erectile function. Preservation of antegrade hypogastric flow with any repair is associated with early improved erectile function; however, it is not a sustained benefit. There is limited benefit of maintaining bilateral hypogastric artery perfusion for this specific indication in unselected men undergoing AAA repair.

Adjunct internal iliac artery procedures in the context of endovascular abdominal aortic aneurysm repair: anything to stress on the consent form?

Adjunct internal iliac artery (IIA) procedures, such as preoperative embolisation or coverage with iliac branch extensions, are not infrequent in the context of endovascular repair of abdominal aortic aneurysms. Moreover, on many occasions, these procedures are performed in a multi-stage approach by interventional radiologists prior to the main operation. Bearing in mind the potential complications of IIA occlusion when revascularization is not initially deemed necessary, various issues arise spanning from appropriate patient counselling to medicolegal consequences. Herein, we aim to provide a roadmap regarding appropriate patient consenting, highlighting the need for multidisciplinary approach of these patients.

Quality of Life of Patients Treated for Abdominal Aortic Aneurysm: Open Surgery and Endoprosthesis

Objectives: To determine the degree of long-term health-related quality of life (HRQoL) of patients undergoing surgery for abdominal aortic aneurysm (AAA) and to analyze the results according to the type of treatment, namely, open abdominal repair (OAR) or endoprosthesis (EVAR). Patients and Methods: This was a prospective cross-sectional observational study. Patients receiving intervention for AAA between January 2013 and December 2020 were included. The Spanish version of the SF-36 questionnaire was used. A single survey was performed on all patients, and the time elapsed since the intervention was recorded. Results: On all health scales and in the two groups of patients, the highest scores were recorded at six months postoperatively. At that time, the EVAR and OAR groups had similar values. Between 13 and 16 months postoperatively, EVAR patients presented a transient but significant decrease in their scores for physical function (p = 0.016), vitality (p = 0.035) and social function (p = 0.041). From that moment, there were progressive decreases in the scores of the two groups of patients on all the scales of the SF-36 questionnaire, although this trend was less pronounced in the OAR group. At 60 months after the intervention, the latter group showed significantly higher values than EVAR for physical function (p = 0.01), vitality (p = 0.032) and mental health (p = 0.029). Additionally, at 60 months after the intervention, the Sum of the psychological component (MCS) and Sum of the physical component (PCS) scores were significantly higher in the OAR group (p = 0.040 and p = 0.039, respectively). Conclusions: In the short term, patients treated for AAA by EVAR or OAR showed similar results on the SF-36 questionnaire. In the long term, patients treated by EVAR had lower scores on the physical function, vitality and mental health scales.

Prevalence of Erectile Dysfunction in Patients With Abdominal Aortic Aneurysm: An Exploratory Study

Introduction

Erectile dysfunction (ED) is defined as the recurrent inability to achieve and maintain a satisfactory erection for sexual intercourse. Many studies have highlighted that ED shares common cardiovascular risk factors with cardiovascular disease. No data are reported about the prevalence of ED in patients with the abdominal aortic aneurysm (AAA). The aim of our study was to investigate the preoperative information given about sexual functions of patients undergoing endovascular aneurysm repair (EVAR) and to compare it with the presence and severity of steno-occlusive atherosclerotic lesions of the pelvic arterial tree at pre-operative Computed Tomography Angiography (CTA).

Methods

We prospectively enrolled all men patients who underwent elective EVAR from September to November 2021. Preoperative ED was evaluated using the International Index of Erectile Function (IIEF-5) questionnaire. Preoperative imaging was routinely performed with CTA scan of the abdominal aorta and iliac-pelvic district. An innovative score of pelvic arterial disease associated to AAA was defined, dividing the iliac district in 4 zones attributing a grading of severity for each zone bilaterally (score ranges 0–24). Linear regression analysis was used to correlate IIEF-5 score to anatomical score of pelvic arterial steno-occlusive disease.

Results

A total of 25 patients were enrolled. Median age was 74 ± 5.3 years. IIEF-5 average score was 14.8 ± 7.1. Eight cases (32%) had severe ED; one case (4%) had moderate, five patients (20%) had mild to moderate ED; five patients (20%) had mild ED, and 6 (24%) patients had no ED. CTA evaluation revealed an average anatomical score of 7.9 ± 4.5. Pelvic disease was considered moderate-severe in 20 cases (80%) and not significant in 20% (five cases). Linear regression analysis confirmed the hypothesis that a more diseased pelvic arterial tree was correlated to a more severe ED (Y = −1.531^* × + 26.35 [slope CI: −1.946 to −1.117, p < 0.0001]).

Conclusion

Although typically unreported, the prevalence of ED associated to AAA was found to be high. A vasculogenic origin of ED in patients with AAA is plausible and may be easily confirmed by the evaluation of pelvic arterial distribution at angio-CT performed for EVAR planning. Our proposed “MAPPING AND SCORING SHEET” may help to identify the vasculogenic origin of ED in AAA patients.

Sexual Dysfunction Before and after Treatment of Infrarenal Aortic Aneurysm Patients

OBJECTIVE

Sexual dysfunction is supposed to be one major complication after treatment of infrarenal aortic aneurysms. It is still controversial how many patients suffer from a sexual dysfunction already before their operation and if there are any procedure-specific differences in postoperative sexual function depending on the operative procedure performed, for example, open (OAR) or endovascular aortic repair (EVAR).

METHODS

To answer these questions we conducted this prospective unicentric study using the International Index of Erectile Function (IIEF) and analyzed the sexual function of 56 male patients with an infrarenal aortic aneurysm before as well as 3, 6, and 12 months after their operation. 23 patients (median age 66.5 years) were treated by OAR and 33 patients (median age 75.8 years) by EVAR.

RESULTS

We observed that the majority of the 56 patients analyzed (91.3% of the 23 OAR patients and 96.8% of the 33 EVAR patients) suffered from a sexual dysfunction already before their operation. A 56.5% of the OAR patients and 67.7% of the EVAR patients even disclaimed a severe sexual dysfunction prior to surgery. Age and operation method showed no significant influence on the IIEF score (P= 0.647 and P= 0.621, respectively). The change of the IIEF score over the 4 time points also did not significantly differ for age and operation method (P= 0.713 and P= 0.624, respectively). The IIEF scores were significantly different between time points T1 and T4 (P= 0.042), whereas between the other time points no significant differences were found.

CONCLUSIONS

Sexual dysfunction is very common in infrarenal aortic aneurysm patients even before their operation. OAR and EVAR do not cause a procedure-specific deterioration of the sexual function.

Outcomes Analysis of Surgical Conversion for Kissing-Stent Occlusion

BACKGROUND

We aimed to describe the operative outcomes following open aortoiliac/femoral graft reconstruction for bilateral kissing-stent (KS) occlusion.

METHODS

This is a bicentric, retrospective, observational cohort study. Between September 2007 and December 2019, 205 patients were treated with KS for aortoiliac reconstruction. Only those who had bilateral KS occlusion with subsequent aortoiliac/femoral graft replacement were included in this analysis. Primary outcomes were early (<30 days) and late survival, postoperative (<30 days) complications, and patency rates.

RESULTS

Nine patients (male, n = 7) were analyzed. The patient's mean age was 60 ± 5 years (range 55-62). Median delay from initial KS procedure was 36 months (interquartile range [IQR] 19-252). On admission, all patients presented with a worse Rutherford class compared to their initial pre-KS clinical presentation. Aortobifemoral bypass was performed in 5 patients, and aortobi-iliac reconstruction in 4 patients. There were no perioperative deaths and only 1 new case of erectile dysfunction occurred. At a median follow-up time of 24 months (IQR 12-54), primary patency rate was 88.9%.

CONCLUSIONS

Open aortic reconstruction after KS occlusion was feasible and effective. Endovascular repair for aortoiliac obstructive disease may be pursued as first-line treatment even in complex lesions.

Analysis of Sexual Disorders in Men with Infrarenal Abdominal Aortic Aneurysm Treated by Stent-Graft or Prosthesis Implantation-A Pilot Study

Background and objectives: Patients with obstruction or stenosis of the aorta and iliac arteries or with aortic aneurysm, often co-existing with iliac artery aneurysms, suffer from sexual disorders because of insufficient perfusion to the pelvic organs and penis. This is often the cause of visits to a medical doctor's office with reports of a difficult life situation and a problem with the satisfactory completion of sexual intercourse. A low percentage of vascular surgeons or angiologists are prepared to talk about issues related to the hereditary sphere with a patient who qualifies for the treatment of Leriche syndrome or abdominal aortic aneurysm. The aim of this study was to analyze sexual disorders in men with infrarenal abdominal aortic aneurysm treated by stent-graft or prosthesis implantation. Material and methods, Outcomes: 38 patients who completed the IIEF-5 (International Index of Erectile for Men) questionnaire are presented. Initially, 146 qualified for the study after meeting the study inclusion criteria for surgery (Group 1) or for endovascular treatment of abdominal aortic aneurysm (Group 2). Results: In the study, no negative impact of smoking was found; however, over 95% of respondents had been smoking for many years in both groups. Patients who qualified for vascular prosthesis implantation were subject to a more advanced atherosclerotic process involving the aorta and iliac arteries. Patients who qualified for stent-graft implantation were twice as often treated for coronary vessel stenosis. In Group 1, the percentage differences, as shown by questions 1 and 5, were statistically significant (58, i.e., 25%, and 40, i.e., 29%). Conclusions: Education should target medical personnel in terms of conversations with patients, as well as men who are directly affected by this problem, although their partners and families should not be neglected in these activities. The ability to communicate properly allows for an open dialogue on issues that the patient finds difficult, particularly in the field of sexology.

Sexual dysfunction after elective laparoscopic or endovascular abdominal aortic aneurysm repair in men

INTRODUCTION

Infrarenal abdominal aortic aneurysm (AAA) repair can lead to ejaculation and erection troubles in men. There are few studies on sexual dysfunction after endovascular repair (EVAR) but they suggest less retrograde ejaculation than after open repair. We assessed the sexual dysfunction and ejaculation troubles after elective laparoscopic repair or EVAR.

METHODS

We conducted a monocentric prospective study on 124 patients undergoing AAA repair between 2013 and 2015. Sexual function was evaluated using the IIEF-15 questionnaire and questions on ejaculation.

RESULTS

Only 45 patients (36.3%) accepted to complete the IIEF preoperatively with 20-37.8% having preoperative sexual dysfunction. Among them, 21 (46.7%) accepted to complete the questionnaire at 3, 6 and 12 months. Mean age at inclusion was 65±5.6 years in the laparoscopic group and 77±10.5 years in the EVAR group (P=0.003). Erectile and sexual function were slightly improved at 12 months in the laparoscopic group (+1.4 for erectile score and +4.6 for IIEF score) with no significant difference (P=0.83 and 0.74) whereas 8 patients (61.5%) had persistent ejaculation troubles at 3 months. In the EVAR group, patients had moderate sexual dysfunction at baseline without improvement at 12 months, but only one patient reported ejaculation troubles.

CONCLUSIONS

Most patients eligible for AAA repair present with baseline erectile and sexual dysfunction. Laparoscopic AAA repair provides no onset of erectile or sexual dysfunction but a global improvement after surgery. Ejaculation troubles are frequent and persistent at 1 year. However, EVAR treatment, doesn't allow recovering of sexual function at 1 year.

Design of new patient-reported outcome measures to assess quality of life, symptoms and treatment satisfaction in patients with abdominal aortic aneurysm

Background

No condition-specific patient-reported outcome measures exist for patients with abdominal aortic aneurysm (AAA). The aim of this work was to develop three questionnaires to assess quality of life (QoL), symptoms and treatment satisfaction in patients with AAA.

Methods

Semistructured interview techniques were used to explore patients' experiences of having an AAA in a series of focus groups and in-depth interviews. The information gathered was used to inform design and selection of items for the new tools; the overall structure of the new questionnaires was based on tools developed previously for patients with diabetes and other conditions.

Results

Fifty-four patients (51 men, 3 women; mean age 71·9 years) were recruited from four NHS Trusts to participate in focus groups or interviews, either while under surveillance, or following AAA repair (using open or endovascular techniques). The Aneurysm-Dependent Quality of Life Questionnaire (AneurysmDQoL) is an individualized measure of the impact of AAA on patients' QoL. Twenty-three domains were chosen specifically for their relevance to patients with AAA, with a further two overview items to assess overall QoL and the impact of AAA on QoL. The Aneurysm Symptom Rating Questionnaire (AneurysmSRQ) is a 44-item measure assessing physical and psychological symptoms reported by patients with AAA. The Aneurysm Treatment Satisfaction Questionnaire (AneurysmTSQ) contains 11 items, suitable for patients before and after surgical intervention.

Conclusion

The iterative development process reported here has confirmed that these three new tools have good face and content validity for patients with AAA.

Impairment of erectile function after elective repair of abdominal aortic aneurysm

The purpose of the present study was to compare the functional change of erectile dysfunction after endovascular repair (EVAR) and open repair (OR) of abdominal aortic aneurysm.

Between April 2009 and December 2011, male patients admitted for elective treatment of an asymptomatic infrarenal abdominal aortic aneurysm were included. The erectile function was evaluated by using a validated KEED questionnaire. All patients filled out the questionnaire preoperatively and postoperatively after one year.

The number of patients with an increase of erectile dysfunction was 8 (26.6%) to 16 (53.3%) in open repair group vs. 30 (42.6%) to 40 (58.8%) in endovascular aneurysm repair. There was no statistically significant difference between open repair and endovascular aneurysm repair groups in order of new incidence of erectile dysfunction ( p = 0.412). The study showed an increase in the mean value of Erectile Dysfunction -Score postoperatively in both the groups as well.

The present study showed an increase of erectile dysfunction postoperatively, but the difference between the two groups was not statistically significant.

Clinical impact of hypogastric artery occlusion in endovascular aneurysm repair

Purpose

To report the long-term results for patients treated with endovascular aneurysm repair and additional embolization and coverage of the hypogastric artery compared with patients treated with simple endovascular aneurysm repair.

Methods

A database of our endovascular aneurysm repair patient cohort was reviewed to find patients with iliac artery aneurysms. The baseline characteristics, the procedural data and the results for patients treated with endovascular aneurysm repair and concomitant hypogastric artery embolization were compared with those for patients treated with simple endovascular aneurysm repair. The results were analyzed for significant differences.

Results

Of 106 endovascular aneurysm repair patients treated at our vascular unit from 2001 to 2010, 24 had undergone additional hypogastric artery embolization. The complication rate was significantly increased in this group (12.5% vs. 2.4%; p = 0.041), and the long-term results were significantly poorer. Additional hypogastric artery embolization resulted in late rupture (1.2% vs. 12.5%; p = 0.036), buttock claudication (8.6% vs. 43.8%; p = 0.001) and new onset erectile dysfunction (17.3% vs. 42.9%; p = 0.043).

Conclusion

Endovascular aneurysm repair with extension of the stent graft to the external iliac artery and embolization of the hypogastric artery was associated with more complications and worse long-term results compared with simple endovascular aneurysm repair.

A systematic review of the correlates and management of nonpremature ejaculatory dysfunction in heterosexual men

INTRODUCTION

A better understanding of ejaculatory disorders has led to an increasing interest in nonpremature ejaculatory dysfunction (non-PE EjD). Current reviews on the subject use a symptom-based classification to describe ejaculatory dysfunction even when it is a single case report. While these reviews provide important information on the disorder, a clearer picture of the prevalence of non-PE EjD in relation to the community and various pathophysiologic states is needed.

OBJECTIVES

The objective of this study was to provide a systematic review of studies of non-PE EjD excluding single case reports.

METHODS

A systematic review of Medline for terms including ejaculation, orgasm or hematospermia. Association with terms delay, pain or headache was made. The search was restricted to male gender and articles written in English. Abstracts were reviewed and those mainly concerned with premature ejaculation were excluded.

RESULTS

A total of 333 articles on non-PE EjD were identified. The condition was reported in community-based studies. In certain patient populations, non-PE EjD was commonly reported in association with antidepressant and antipsychotic treatments, in patients with chronic prostatitis/chronic pelvic pain syndrome, patients with lower urinary tract symptoms particularly in association with medical or surgical treatment, patients with retroperitoneal surgery and in patients with neurological diseases. Few articles were concerned with treatment options.

CONCLUSION

There is a significant prevalence of non-PE EjD in the community and in association with particular disease states or as a side effect of medical or surgical interventions. There is a need to direct efforts to prevent and treat these conditions.

Questions remain about quality of life after abdominal aortic aneurysm repair

INTRODUCTION

Morbidity and mortality have traditionally been used as key markers of surgical outcome. However, as complication rates associated with abdominal aortic aneurysm (AAA) repair decrease, subjective measures, such as quality of life (QOL), are increasingly recognized as important indicators of treatment efficacy and quality of care. This review presents the existing evidence relating to QOL changes in patients undergoing AAA repair by open repair (OR) and endovascular techniques (EVAR) and challenges current misconceptions about the relative effect of these two procedures.

METHODS

A comprehensive literature search was performed to identify studies relating to QOL or health status in AAA repair. Quality of included studies was assessed according to Scottish Intercollegiate Guidelines Network methodology.

RESULTS

Twenty-three studies satisfied the inclusion criteria. Preoperative QOL in AAA patients has been previously suggested as being worse than that of the general population, that OR patients have a worse QOL in the early postoperative period, and that EVAR patients have a worse QOL in the longer term. None of these assertions is uniformly supported in the literature. From the existing evidence, no clear conclusions can be drawn about the relative QOL benefits of OR vs EVAR.

CONCLUSIONS

There are a paucity of good-quality data relating to health status and QOL in patients undergoing AAA repair. Little is known about the prevalence of preoperative or postoperative symptoms and the degree to which these influence patient well-being. Further investigation is needed to clarify health status and QOL changes in these patients and allow clinicians to make targeted improvements in practice.

Experience and outcomes after a decade of endovascular abdominal aortic aneurysm repair: a retrospective study from a community-based single center

BACKGROUND

The purpose of this study is to report the results of endovascular abdominal aortic aneurysm treatment based on the Zenith stent-graft from a community-based single center over a period of 9 years.

METHODS

We retrospectively analyzed immediate technical and clinical results as well as long-term outcomes in patients treated with endovascular aneurysm repair between 2001 and 2010. The study was performed in accordance with the recommendations of the ad hoc committee for standardized reporting practice in vascular surgery.

RESULTS

A total of 106 patients were treated in a period of 9 years. A Zenith stent-graft was used in 95% of cases. No deaths occurred during the first 30 days postsurgery. The complication rate was 4.7% (n = 5). The overall clinical and technical success rate at 30 days was 93.4%. After a mean follow-up period of 52 months (range, 13-112 months), the overall mortality rate was 25.4%. Aneurysm-related mortality was 2.1%. Rupture of the aneurysm occurred in four cases (4.3%). The final clinical failure rate was 13.8%. During the follow-up period, the mean diameter of the aneurysm decreased from 58.0 to 52.3 mm. However, expansion of the aneurysm was registered in 10 cases. Eleven patients had a primary endoleak, and another 11 secondary endoleaks occurred during the follow-up. The reintervention rate was 16.3%. The main reasons for repeat interventions were iliac limb occlusion (n = 5) and type 3 endoleak/limb disconnection (n = 4). Graft migration occurred in 3% of cases. A negative impact on sexual function after endovascular repair was reported by 20% of patients.

CONCLUSION

Endovascular repair is the treatment of choice for high-risk patients. A small but significant number of clinical failures were observed during the long-term follow-up.

The drama of being diagnosed with an aortic aneurysm and undergoing surgery for two different procedures: open repair and endovascular techniques

The purpose of this study is to describe and interpret what it means for patients to be diagnosed with an abdominal aortic aneurysm (AAA) and how they experience treatment. AAA is usually asymptomatic and often discovered coincidentally in conjunction with a diagnostic workup for other medical problems. Twenty patients who had undergone 2 different surgical procedures were sequentially invited for interviews 1 month following surgery. A hermeneutic approach was used. For all patients three themes emerged: an inability to come to terms with a life-threatening condition, a sense of living on borrowed time, and a sense of being granted a new lease on life. The theme that emerged for patients with open repair was that diagnosis with AAA was an ordeal to endure, while the theme for patients who underwent endovascular treatment was a sense of gratitude, security, and insecurity. Once the aneurysm was discovered patients were convinced that they were both blessed and saved, along with a sense of gratitude. Pre- and postoperative nursing care strategies can be developed based on the findings from this study.

Sexual dysfunction after elective endovascular or hand-assisted laparoscopic abdominal aneurysm repair

OBJECTIVE

To evaluate the incidence of sexual dysfunction and retrograde ejaculation after elective endovascular aneurysm repair (EVAR) and hand-assisted laparoscopic surgery (HALS) for abdominal aortic aneurysm (AAA).

METHODS

A total of 100 patients eligible for elective repair of infrarenal AAAs were randomised in two groups: EVAR and HALS. The quality of sexual function was evaluated using the International Index of Erectile Function (IIEF), a 15-item questionnaire. Patients completed the IIEF preoperatively and at 12 months. The incidence of retrograde ejaculation was also evaluated.

RESULTS

One- and 12-month mortality rates were zero. Three patients in the EVAR group (6%) and two patients in the HALS group (4%) reported an erectile dysfunction (p = NS). The quality of sexual function at 1 year was similar in both groups: total score of 66 in the EVAR group versus 68 in the HALS group (p = 0.66). Retrograde ejaculation was detected in three cases in the HALS group versus no case in the EVAR group.

CONCLUSIONS

The HALS technique could be a minimally invasive alternative for sexually active males unsuitable for EVAR repair.
