Quality of life assessment in patients undergoing endovascular or conventional AAA repair

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.

Towards Patient Centred Outcomes for Elective Abdominal Aortic Aneurysm Repair: A Scoping Review of Quality of Life Scales

OBJECTIVE

In order to better incorporate the patient's perspective in medical decision making, core outcome sets (COS) are being defined. In the field of abdominal aortic aneurysm (AAA), efforts to capture the patient's perspective focus on generic quantitative quality of life (QoL) scales. The question arises whether these quantitative scales adequately reflect the patient's perspective on QoL, and whether they can be included in the QoL aspect of COS. A scoping review of QoL assessment in the context of elective AAA repair was undertaken.

DATA SOURCES

PubMed, Embase, Web of Science, and the Cochrane Library.

REVIEW METHODS

A scoping review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Articles reporting QoL assessment in the context of elective AAA repair were identified. Quantitative studies (i.e., traditional QoL scales) were aligned (triangulation approach) with qualitative studies (i.e., patient perspective) to identify parallels and discrepancies. Mean Short Form 36 item survey (SF-36) scores were pooled using a random effects model to evaluate sensitivity to change.

RESULTS

Thirty-three studies were identified, of which 29 (88%) were quantitative and four (12%) qualitative. The 33 studies reported a total of 54 quantitative QoL scales; the most frequently used were the generic SF-36 (16 studies) and five dimension EuroQol (EQ-5D; eight studies). Aneurysm specific scales were reported by one study. The generic quantitative scales showed poor alignment with the patient's perspective. The aneurysm specific scales better aligned but missed "concerns regarding symptoms" and "the impact of possible outcomes/complications". "Self control and decision making", which was brought forward by patients in qualitative studies, was not captured in any of the current scales.

CONCLUSION

There is no established tool that fully captures all aspects of the patient's perspective appropriate for a COS for elective AAA repair. In order to fulfil the need for a COS for the management of^, AAA disease, a more comprehensive overview of the patient's perspective is required.

Life is about so much more: Patients' experiences of health, well-being, and recovery after operation of abdominal aortic aneurysm with open and endovascular treatment-A prospective study

Different surgical treatments for abdominal aortic aneurysm can lead to different perceptions of health and well-being. The aim of this study was to describe patients' well-being, sense of coherence (SOC), and experiences of surgery after open and endovascular treatment one month and one and 2 years after the procedure. Seventy six patients participated (40 open repair; 36 endovascular aneurysm repair). The study was conducted using the SOC questionnaire, and specific questions about patients' experiences of the surgical treatment and well-being. After 2 years, no patient regretted the operation or considered it to be the most difficult experience they had ever had. Twenty percent of the patients were worried about complications one month after the operation. Both groups experienced difficulty in returning to normal activity after surgery at one month. At one and 2 years after the surgery, patients in both groups stated that it was other things in life that affected their well-being. The endovascular aneurysm repair group reported a significant decrease in SOC from baseline until one year (P = .012) and 2 years (P = .033). The open repair group reported a significant decrease after one year (0.033). The operation did not affect patients' way of thinking about the disease. Patients in both groups stated that it was other circumstances in life that affected their well-being one and 2 years after the treatment, which could indicate that long-term follow-up would not be necessary from a patient perspective. The operation affects patients' well-being a short time after the operation.

Quality of life from a randomized trial of open and endovascular repair for abdominal aortic aneurysm

Background

Long-term survival is similar after open or endovascular repair of abdominal aortic aneurysm. Few data exist on the effect of either procedure on long-term health-related quality of life (HRQoL) and health status.

Methods

Patients enrolled in a multicentre randomized clinical trial (DREAM trial; 2000–2003) in Europe of open repair versus endovascular repair (EVAR) of abdominal aortic aneurysm were asked to complete questionnaires on health status and HRQoL. HRQoL scores were assessed at baseline and at 13 time points thereafter, using generic tools, the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36®) and EuroQol 5D (EQ-5D™). Physical (PCS) and mental component summary scores were also calculated. Follow-up was 5 years.

Results

Some 332 of 351 patients enrolled in the trial returned questionnaires. More than 70 per cent of questionnaires were returned at each time point. Both surgical interventions had a short-term negative effect on HRQoL and health status. This was less severe in the EVAR group than in the open repair group. In the longer term the physical domains of SF-36® favoured open repair: mean difference in PCS score between open repair and EVAR −1·98 (95 per cent c.i. −3·56 to −0·41). EQ-5D™ descriptive and EQ-5D™ visual analogue scale scores for open repair were also superior to those for EVAR after the initial 6-week interval: mean difference −0·06 (−0·10 to −0·02) and −4·09 (−6·91 to −1·27) respectively.

Conclusion

In this study EVAR appeared to be associated with less severe disruption to HRQoL and health status in the short term. However, during longer-term follow-up to 5 years, patients receiving open repair appeared to have improved quality of life and health status.

Construct domain analysis of patient health-related quality of life: physical and mental trajectory profiles following open versus endovascular repair of abdominal aortic aneurysm

Purpose

Many clinical trials comparing the outcomes of open surgical repair (OSR) versus endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) have been conducted, with varying results. Surprisingly, few outcomes studies have closely examined perceived physical and mental health-related quality of life (HRQOL) factors through a validated survey tool. The purpose of this prospective observational study was to describe the trajectory of HRQOL measures, from baseline to 1 year after surgery, in patients undergoing OSR or EVAR for AAA, and to explore for differences in physical and mental composite scores and their construct domains (subscales) using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36^®) tool.

Patients and methods

Over an 18-month period, a small sample of patients undergoing elective AAA repair in a community hospital setting were prospectively enrolled. Fifteen patients undergoing OSR and twenty patients undergoing EVAR were studied. Physical and mental HRQOL parameters were assessed using the SF-36.

Results

No significant differences in demographic and clinical variables were found between the OSR and EVAR groups. In the multivariable linear models with repeated measures, both groups showed a significant decline in physical health composite scores 30 days after the surgical procedure (P < 0.01). However, although the OSR group showed a statistically significant decline in three of the four physical health domains, the EVAR group declined in only one physical health domain. Only the OSR group showed a significant decline in three of the four mental health domains at 30 days; however, the decline of these domains was not reflected in the group’s mental health composite scores. By 90 days after surgery, both groups were not significantly different from their baseline in physical or mental health composite scores, or in any of their respective physical health domains.

Conclusion

In this small sample of patients undergoing AAA repair, EVAR resulted in less physical and emotional decline than OSR in the early postoperative period. However, patients in both groups may return to near baseline status at 90 days.

Meta-analysis of prospective trials determining the short- and mid-term effect of elective open and endovascular repair of abdominal aortic aneurysms on quality of life

Background

Repair of an abdominal aortic aneurysm (AAA) is undertaken to prevent rupture. Intervention is by either open repair (OR) or a more minimally invasive endovascular repair (EVAR). Quality-of-life (QoL) analysis is an important health outcome and a number of single studies have assessed QoL following OR and EVAR. This was a meta-analysis of published studies to assess the effect of an intervention on QoL in patients with an AAA.

Methods

A systematic literature search was undertaken for studies prospectively reporting QoL analysis in patients with an AAA undergoing elective intervention. A multivariable meta-analysis model was developed in which the outcomes were mean changes in QoL scores over time, both for all AAA repairs (OR and EVAR) and comparing OR with EVAR.

Results

Data were collated from 16 studies (14 OR, 12 EVAR). The results suggested that treating an AAA had an effect on patient-reported QoL, evident from the statistically significant changes predominantly in domains assessing physical ability and pain. QoL was affected most within the first 3 months after any form of intervention, and was more pronounced following OR. Furthermore, a deterioration in the Physical Component Summary score following an AAA repair (either OR or EVAR) was evident at 12 months after intervention.

Conclusion

Treating an AAA deleteriously affects patient-reported QoL over the first year following intervention.

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.

The Impact of Hospital Volume on the Development of Infectious Complications After Elective Abdominal Aortic Surgery in the Medicare Population

Objective: A relationship exists between higher hospital volume and lower mortality, yet the impact of hospital volume on infectious complications after elective abdominal aortic aneurysm (AAA) repair is unknown. Methods: The Medicare database (2005-2007) was utilized. Top 10% for volume were categorized as high-volume (HV) and compared to low-volume (LV) centers for infectious complications and utilization. Results: A total of 42 155 endovascular aneurysm repair (EVAR) and 17 210 open AAA were identified. Mortality in HV was significantly lower than in LV after EVAR and open AAA. After EVAR, HV had lower than LV rates of overall infection (3.10% vs 3.51%; P = .021), PNA (0.94% vs 1.27%, P = .002), and sepsis (0.31% vs 0.45%; P = .03). Length of stay (LOS) and total hospital charges were significantly lower at HV compared to LV after both EVAR and open AAA. Conclusion: For Medicare beneficiaries, undergoing elective AAA repair at hospitals performing higher volume significantly reduced postoperative infectious complications and hospital resource utilization. Further analysis identifying systematic reasons for disparities may offer cost savings and improve outcomes.

Age stratified, perioperative, and one-year mortality after abdominal aortic aneurysm repair: a statewide experience

OBJECTIVE

The purpose of this study was to determine the in-hospital, 30-day, and 365-day mortality for the open repair of abdominal aortic aneurysms (AAAs), when stratified by age, in the general population. Age stratification could provide clinicians with information more applicable to an individual patient than overall mortality figures.

METHODS

In a retrospective analysis, data were obtained from the California Office of Statewide Health Planning and Development (OSHPD) for the years 1995 to 1999. Out-of-hospital mortality was determined via linkage to the state death registry. All patients undergoing AAA repair as coded by International Classification of Diseases, 9th Revision (ICD-9) procedure code 38.44 and diagnosis codes 441.4 (intact) and 441.3/441.5 (ruptured) in California were identified. Patients <50 years of age were excluded. We determined in-hospital, 30-day, and 365-day mortality, and stratified our findings by patient age. Multivariate logistic regression was used to determine predictors of mortality in the intact and ruptured AAA cohorts.

RESULTS

We identified 12,406 patients (9,778 intact, 2,628 ruptured). Mean patient age was 72.4 +/- 7.2 years (intact) and 73.9 +/- 8.2 (ruptured). Men comprised 80.9% of patients, and 90.8% of patients were white. Overall, intact AAA patient mortality was 3.8% in-hospital, 4% at 30 days, and 8.5% at 365 days. There was a steep increase in mortality with increasing age, such that 365-day mortality increased from 2.9% for patients 51 to 60 years old to 15% for patients 81 to 90 years old. Mortality from day 31 to 365 was greater than both in-hospital and 30-day mortality for all but the youngest intact AAA patients. Perioperative (in-hospital and 30-day) mortality for ruptured cases was 45%, and mortality at 1 year was 54%.

CONCLUSIONS

There is continued mortality after the open repair of AAAs during postoperative days 31 to 365 that, for many patients, is greater than the perioperative death rate. This mortality increases dramatically with age for both intact and ruptured AAA repair.

Health-related quality of life in survivors of open ruptured abdominal aortic aneurysm repair: A matched, controlled cohort study

OBJECTIVE

The objective of this study was to document the health-related quality of life (HRQOL) for patients who survived operative repair of a ruptured abdominal aortic aneurysm (RAAA) and to compare this with a matched group of patients who survived elective operative repair of an abdominal aortic aneurysm (EAAA).

METHODS

A matched, controlled cohort study of HRQOL was used to compare patients surviving RAAA with an EAAA control group. The study was conducted at two university-affiliated vascular tertiary care referral centers. Survivors of RAAA and EAAA during an 8.5-year period were identified and followed up. The RAAA and EAAA control patients were matched for age, serum creatinine concentration, gender, and duration of follow-up since surgery. HRQOL was measured with the Medical Outcomes Study Short Form-36 Health Survey (SF-36). Scores for the EAAA and RAAA cohorts were also compared with age-corrected SF-36 population scores.

RESULTS

Of 267 patients operated for RAAA during the study period, 130 (49%) survived to hospital discharge. Death after discharge was documented in 35 patients, leaving a potential study population of 95 RAAA survivors. Thirteen were lost to follow-up, seven refused to participate, and four patients were not able to participate. The SF-36 was completed by 71 RAAA patients (75% of surviving RAAA patients). The 71 RAAA survivors and 189 EAAA control patients were similar for seven of eight domains of the SF-36: Physical Function, Role-Physical, Bodily Pain, General Health, Vitality, Mental Health, and Role-Emotional. There was also no difference in the Physical Health Summary and Mental Health Summary scores. The social function component of the SF-36 demonstrated a statistically significant decline in the EAAA group. Both the EAAA and RAAA SF-36 individual and summary scores compared favorably with population norms that were adjusted only for age.

CONCLUSION

Long-term survivors of RAAA enjoy a HRQOL that does not differ significantly from EAAA survivors. Scores for both groups compare favorably with population scores adjusted only for age.

Challenges associated with the integration of endovascular repair of abdominal aortic aneurysms in a community hospital

PURPOSE

There has been considerable debate regarding the proper place for endovascular repair (ER) of abdominal aortic aneurysms (AAAs) versus traditional open repair (OR). Our study compared preoperative patient demographics and outcomes for elective, asymptomatic AAA repairs performed at our center over a 33-month period.

METHODS

For this study, we selected 342 consecutive elective infrarenal AAA repairs performed between July 1, 2000, and March 31, 2003, at Riverside Methodist Hospital. The patients underwent either ER or OR, depending on patient and surgeon collaborative determinations. Ruptured and symptomatic AAAs were excluded from our study. Preoperative demographics, anesthesia, complications, and discharge status for the 2 groups were analyzed, and statistical analysis was done to determine statistically significant differences.

RESULTS

The preoperative status of the ER and OR patient groups were essentially similar. There were only 3 significant differences between the 2 groups: alcohol use was higher for the OR group than for the ER group (12.0% versus 5.2%; P = .04), and the incidence of type II diabetes mellitus and peripheral vascular disease were lower for the OR group compared with the ER group (6.7% versus 13.4% [P = .04] and 18.3% versus 30.6% [P = .008], respectively). The OR group used more general anesthesia than the ER group (99% versus 86%; P < .001) and had more complications, including dysrhythmia (8.65% versus 1.59%; P = .005), ileus (13.94% versus 0.79%; P < .0001), infection (8.17% versus 0.0%; P = .0007), respiratory complications (12.50% versus 1.59%; P = .0003), and renal complications (5.29% versus 0.79%; P = .032). The ER group had a higher rate of wound hematoma (4.76% versus 0.48%; P = .007). ER patients also had significantly less blood loss (379 mL versus 1930 mL; P < .001), a better independent discharge status (P < .0001), a shorter length of stay (1.8 days versus 8.2 days; P < .001), and a lower mortality rate (0.75% versus 3.85%; P = .0954).

CONCLUSIONS

From our study we cautiously continue to encourage the consideration of the ER of AAAs in our patient population while being mindful of its limitations.

Patient-reported quality of life after abdominal aortic aneurysm surgery: A prospective comparison of endovascular and open repair

PURPOSE

This study evaluated and compared changes over time in health-related quality of life reported by patients with infrarenal abdominal aortic aneurysm (AAA) undergoing elective endovascular (EVAR) and open aneurysm (OR) repair.

METHODS

A prospective, nonrandomized cohort of 76 patients (62 men, 14 women; age range, 42 to 89 years) undergoing elective, infrarenal AAA repair (EVAR, n = 43; OR, n = 33) at two university teaching hospitals during a 15-month period were administered the Medical Outcomes Study Short-Form 36-item (SF-36) health survey preoperatively and then 1 week, 1 month, and 6 months postoperatively. Patient demographics, procedural details, postoperative follow-up data, and SF-36 scores were compared between groups.

RESULTS

Both groups had total SF-36 scores that were significantly lower than preoperative scores at 1 week and 1 month after surgery but were not significantly different from the preoperative scores at 6 months (OR 66.2 +/- 21.1 to 72.3 +/- 19.8, P > .1; and EVAR 61.0 +/- 17.7 to 58.7 +/- 19.4, P > .1). Six-month total SF-36 scores were significantly higher in the OR group compared with the EVAR group (mean 72.3 +/- 19.8 OR vs 58.7 +/- 19.4 EVAR; P = .009). In the postoperative period, a significant drop occurred in mean scores in six of the eight domains of the SF-36 in the OR patients (physical function, PF; role physical, RP; bodily pain, BP; vitality, VT; social function, SF; role emotional, RE) and five domains for EVAR patients (PF, RP, BP, SF, RE). In two domains, RE and PF, scores returned to baseline values significantly sooner in EVAR patients than in OR patients (RE, EVAR 1 month vs OR 6 months; and PF, EVAR 1 month vs OR 6 months). In the VT domain, no significant postoperative drop occurred in the EVAR group, but in the OR group, mean scores were significantly lower at 1 week and 1 month compared with preoperative values. In the domains of general health and mental health, no significant drop occurred in SF-36 score postoperatively in either group.

CONCLUSIONS

Patient reported health-related quality of life after infrarenal AAA repair is significantly impaired in the early postoperative period but returns to baseline by 6 months in patients treated with EVAR and OR. Patients having EVAR had significantly more rapid return to preoperative scores in selected domains of the SF-36. Even though EVAR is associated with shorter and less invasive perioperative hospital course and fewer postoperative complications, EVAR patients had lower quality of life scores 6 months after surgery than OR patients.

Pilot study of sexual dysfunction following abdominal aortic aneurysm surgery

INTRODUCTION

The complication of sexual dysfunction as a quality of life (QoL) component after abdominal aortic aneurysm (AAA) surgery in men is poorly studied.

AIMS

To investigate the prevalence of sexual dysfunction and to highlight the importance of discussing this issue with patients undergoing AAA repair.

MAIN OUTCOME MEASURES

The self-reported sexual dysfunction prevalence pre- and postoperatively, the effects on sexual QoL, and the postoperative Sexual Health Inventory for Men (SHIM) scores.

METHODS

Between April 1999 and July 2002, a questionnaire-based study, including the SHIM, was conducted on male patients 1-2 years after their elective open (EO) and rupture open (RO) or endovascular repair (EVAR) AAA repair. Demographics, risk factors for sexual dysfunction, sexual history, and postoperative sexual QoL data were obtained.

RESULTS

Out of 142 alive male patients surveyed, 56 (40%) patients responded (26 EO, 21 EVAR, and 9 RO repair). The mean age was 69, 73, and 70 years, respectively, and 65%, 66%, and 66%, respectively, admitted to be sexually active postoperatively. The self-reported sexual dysfunction prevalence preoperatively was 27% (EO), 63% (EVAR), and 45% (RO); and postoperatively was 58%, 76%, and 67%, respectively. Detection using SHIM was higher at 70%, 95%, and 78%, respectively. There was a significantly greater increase in the postoperative prevalence of sexual dysfunction in the EO group than in the EVAR group (P < 0.05, chi(2)). The sexual QoL was worsened postoperatively in all groups: 53% (EO), 75% (EVAR), and 50% (RO); but only one-third of EO and EVAR patients, and none in RO patients, would seek treatment for their sexual dysfunction.

CONCLUSION

There was a negative impact on the sexual QoL in all groups after surgery, and a significantly higher proportion of patients experienced deterioration in sexual QoL following EO surgical repair. Our results demonstrate the need for a prospective study.

Trends, complications, and mortality in peripheral vascular surgery

BACKGROUND

The recent evolution in treatments for peripheral vascular disease has dated available mortality statistics for vascular intervention. Moreover, many of our current mortality statistics are derived from single-institution studies that are often not reflective of outcomes in general practice. To provide current and generalizable data regarding mortality and trends for peripheral vascular interventions, we examined two national data sets (Nationwide Inpatient Sample, 1998-2003, and National Hospital Discharge Survey, 1979-2003) and four states (New York, California, Florida, and New Jersey, 1998-2003).

METHODS

Four procedures--abdominal aortic aneurysm repair (nonruptured), lower extremity revascularization, amputation, and carotid revascularization--were selected by cross-referencing International Classification of Diseases, 9th Revision, diagnostic and procedural codes. For significance, the t test was used for continuous variables, the chi2 test was used for dichotomous variables, and the chi2 test was used for mortality trends.

RESULTS

From 1998 to 2003, there was a progressive decrease in the national per capita rate of amputations: 13.2% overall and 21.2% for major amputations (P < .0001). Nationally and regionally, mortality has only slightly declined. For lower extremity revascularization, after a sharp increase during the 1980s to 100,000 open procedures, the volume remained constant for 10 years and began to decline in 1998, reaching 70,000 cases in 2003. In contrast, since 1996, endovascular interventions have increased 40%. Mortality during the 1998 to 2003 period remained virtually stable at 1.5% to 2% for endovascular procedures and 3% to 4% for open procedures. The overall volume of abdominal aortic aneurysm repair has not changed substantially for the past 6 years; however, endovascular repair is now used for nearly half the cases (46.5% regional and 43.0% national). Mortality for open repair has not changed, remaining at approximately 5%, whereas for endovascular repair, mortality has declined from 2.6% in 2000 to less than 1.5% in 2003. After the rapid increase in open carotid revascularization in the early 1990s, the total volume has declined 5% nationally from 1998 to 2003. Regional data demonstrated an overall 12% reduction in carotid revascularization volume since 1998; this reduction was due to a 16% decline in open carotid revascularization. During this same period, the use of angioplasty-stent carotid revascularization doubled. Mortality for the open procedures is 0.5% and is significantly higher (2%-3%) for endovascular carotid revascularization. Stroke rates for endovascular carotid revascularization are also higher: 2.13% vs 1.28% for open procedures (P < .0001).

CONCLUSIONS

Dramatic shifts in the management of peripheral vascular disease have occurred together with an overall decline in mortality. There seems to be a significant mortality advantage for endovascular as compared with traditional surgery except for carotid endarterectomy. The increasing safety of vascular interventions should be considered when deciding which patients to treat but with the caveat that endovascular interventions are not always safer than open repair.

Health-Related Quality of Life Outcomes Following Elective Open or Endovascular AAA Repair:A Randomized Controlled Trial

PURPOSE

To assess health-related quality of life outcomes after endovascular versus open abdominal aortic aneurysm repair.

METHODS

Participants were randomly assigned to receive either endovascular or open abdominal aortic aneurysm (AAA) surgery according to a rate of 3 endovascular patients to 1 with open repair. Data on patient characteristics, operative aspects, and procedural and device-related complications were compiled at a single center. Health-related quality of life was assessed before treatment and 1 and 3 months following operation using the Medical Outcomes Study Short-Form 36-item Health Survey (SF-36) and the EuroQol questionnaire.

RESULTS

Between 1996 and 1999, 57 patients (54 men; mean age 69 years, range 52-82) underwent endovascular and 19 patients (16 men; mean age 68 years, range 52-81) underwent open AAA repairs. Preoperatively, comparable scores were recorded in both treatment groups. One month after operation, patients of both groups scored significantly lower on the SF-36 domains of Role Limitations due to physical problems and Pain compared to preoperative scores. Three months after operation, both groups had scores in all domains comparable to preoperative levels of functioning. There was a significant benefit for the endovascular group 1 month after operation in the SF-36 domains of Physical Functioning, Role Limitations due to physical problems, Vitality, and Pain; their score on the EuroQol Usual Activities item was also significantly better. After 3 months, there were no longer differences between groups.

CONCLUSIONS

Short-term health-related quality of life benefits were found after endovascular repair compared with standard open surgery.

Quality of life before and after endovascular and retroperitoneal abdominal aortic aneurysm repair

PURPOSE

This study was undertaken to evaluate changes in quality of life and to compare conventional outcomes in patients undergoing endovascular and open retroperitoneal abdominal aortic aneurysm (AAA) repair.

METHODS

Between October 2000 and May 2003, 129 patients underwent elective AAA repair, endovascular repair in 22 patients and open retroperitoneal repair in 107 patients. The Short-Form Health Survey, 12 items (SF-12) was administered preoperatively and at 3 weeks, 4 months, and 1 year after discharge. Quality of life, hospital and intensive care unit stay, perioperative complications, discharge disposition, readmission, and hospital cost were statistically evaluated.

RESULTS

For the total group, significant differences were observed for both Physical Component Summary scores (P<.001) and Mental Component Summary scores (P=.001) between time points. There were no significant differences for either Component Summary score between open and endovascular procedures for any time period. Number of weeks required to return to baseline functional status was similar after either open or endovascular repair (7.22 vs 5.47 weeks, respectively; P=.09). Mean hospital and intensive care unit stay was 4.4 and 1 days, respectively, for open repair versus 1.9 and 0 days, respectively, for endovascular repair (P<.0001). No significant difference between groups was observed in terms of perioperative complications, discharge disposition, or hospital readmission (P> or =.54). Mean total hospital cost for endovascular repair was 1.60 times that for open repair (mean difference, $11,662; P<.0001; 95% confidence interval, $17,799-$5525).

CONCLUSIONS

Hospital stay is significantly shorter after endovascular AAA repair. However, hospital cost is almost twice that for open retroperitoneal repair. Perioperative complications, discharge disposition, and hospital readmission are not statistically different between the two groups. Effect on health-related quality of life is similar after either open retroperitoneal or endovascular AAA repair.

Quality of Life after Endovascular and Open AAA Repair. Results of a Randomised Triala

AIM

To compare the quality of life (QoL) in the first postoperative year after elective endovascular abdominal aortic aneurysm repair (EVAR) and open repair (OR) in a randomised study.

METHODS

In the Dutch Randomised Endovascular Aneurysm Management (DREAM) trial, patients are randomly allocated to EVAR or OR. QoL questionnaires (SF-36 and EuroQoL-5D) were sent to all patients preoperatively (PREOP) and at five time points in the first postoperative year (3W, 6W, 3M, 6M and 12M). Between November 1999 and August 2002, 153 patients (141 male; 12 female) were randomised (78 EVAR and 75 OR; one crossover from OR to EVAR). The EuroQoL-5D scores and the eight domains of the SF-36 for the two groups were compared using the Mann-Whitney test. Changes over time were analysed using the Wilcoxon sign test.

RESULTS

There were no statistically significant differences in baseline characteristics (age, gender and SVS risk factors). The preoperative QoL scores of the study group were similar to the QoL scores of the general population of the same age. After 3W the OR group showed a significant decrease on the EuroQol-5D (p=0.022) and in six of the eight SF-36 domains. The EVAR group also showed a significant decrease on the EuroQol-5D (p=0.004) and in 5 of the 8 domains of the SF-36. At 6W the EuroQol-5D had recovered to baseline in the OR group and the decreased domains of the SF-36 had partially recovered. In the EVAR group the EuroQol-5D and three of the five decreased SF-36 domains, had returned to baseline. From 6M on, the OR group reported a significantly higher score on the EuroQoL-5D than the EVAR group (p=0.045 (6M) and p=0.001 (12M)).

CONCLUSION

In the early postoperative period there is a small, yet significant QoL advantage for EVAR compared to OR. At 6 months and beyond, patients reported better QoL after OR than after EVAR.

A statewide experience with endovascular abdominal aortic aneurysm repair: Rapid diffusion with excellent early results

OBJECTIVE

The purpose of this study was to compare survival and outcomes of endovascular versus open repair of abdominal aortic aneurysms (AAAs) in New York State (NYS).

METHODS

We used the NYS discharge dataset Statewide Planning and Research Cooperative System (SPARCS) to analyze the outcomes of elective admission for nonruptured (International Classification of Diseases-9th revision [ICD-9] 441.4) open aneurysm repair (38.44) and endovascular aneurysm repair (39.71) during the years 2000-2002. The ICD-9 code for endovascular repair was introduced in late 2000, thus capturing 3 months of empiric data for 2000.

RESULTS

There has been a significant increase in the number of AAA procedures performed in NYS (comparing before and after 2000: average, 1419 vs 1701; P =.0001), temporally coinciding with the implementation of training programs after US Food and Drug Administration approval of endovascular grafts and the new payment code. From 2000 to 2002 the number of NYS hospitals performing endovascular repairs increased from 24 to 60. By 2002 there were more endovascular repairs being performed than open repairs (871 vs 783). The target population for these surgical interventions showed interesting differences. In 2002, women had a 43% chance of receiving an endograft, whereas men had a 55% probability. The use of endovascular repair over the observation period was relatively constant in patients younger than 65 years. In patients older than 65 years, and especially those older than 75 years, endovascular use increased substantially, so that by 2002 older patients were more likely to undergo endovascular repair than open repair. Patients who underwent endovascular repair had significantly more hypertension, coronary artery disease, diabetes, and hyperlipidemia than did patients who underwent open repair. Yet the mean length of stay for endovascular procedures was approximately 3.6 days, and for open procedures was about 10.3 days, across all 3 years (P = <.0001). Moreover, patients who underwent endovascular repair had statistically fewer postoperative complications and significantly lower mortality. In-hospital mortality in 2001 was 3.55% for open repair and 1.14% for endovascular repair (P =.0018), and in 2002 these rates were 4.21% versus 0.8% (P <.0001), respectively.

CONCLUSION

This dataset suggests that endovascular AAA repairs are being performed in a patient population with a higher frequency of comorbidities. However, endovascular repairs still are associated with significantly lower in-hospital mortality, fewer postoperative complications, and a dramatically shorter length of stay. These results suggest that, despite the rapid diffusion of this new technique, early perioperative outcomes may be superior to those with conventional open repair. However, prospective clinical studies are needed to confirm these insights, and such studies may require the infrastructure of consortia of hospitals or society-based registries.

Changes in TH1/TH2 immunity after endovascular and conventional infrarenal aortic aneurysm repair: its relevance for clinical practice

OBJECTIVE

to evaluate local surgical trauma induced by endovascular (TPEG) and conventional infrarenal aortic aneurysm repair (AAA-C), the inflammatory response and changes in cell-mediated and antibody-mediated immunity as illustrated by the type-1/type-2 T-helper (TH1/TH2) cell balance were investigated.

DESIGN

prospective study.

PATIENTS AND METHODS

sixteen patients were included, eight patients underwent AAA-C and eight TPEG. Venous peripheral blood samples were collected 24h preoperatively and 24, 48, 72h, 5 and 7 days postoperatively. Besides the WBC, intracellular TH1/TH2 cytokines (IFN-gamma/IL-4) and the cell surface markers HLA-DR on monocytes and CD23 on B cells were measured by four colour flow cytometry.

RESULTS

statistically significant higher values in the AAA-C group were demonstrated for neutrophiles. The TH1/TH2 immunobalance (expressed by forming the ratio of IFN-(gamma/IL-4 producing T cells as well as by the ratio of HLA-DR(pos) monocytes/CD23(pos) B-cells) showed a significant shift towards TH2 immunity in the AAA-C group whereas TPEG led to a significant lesser shift 24-72h after surgery (p < 0.05).

CONCLUSIONS

TPEG leads to a minor distortion of the TH1/TH2 immunobalance. This implies that TPEG is a less stressing procedure, that is especially beneficial in patients whose conditions are considered less suitable for AAA-C due to age and serious comorbidity.

Early and late functional outcome assessments following endovascular and open aneurysm repair

PURPOSE

To compare early and late functional outcomes, as well as survival and recovery, following endovascular or open repair of abdominal aortic aneurysm (AAA).

METHODS

Between 1996 and 2000, 294 patients underwent AAA repair (141 open and 153 endovascular); 57 patients from each group had 12-month follow-up for functional outcome assessment. Recovery was measured as hospital length of stay, skilled nursing requirement, and hospital readmission within 1 year to determine cumulative hospital utilization. Early (<6 months) functional outcomes were measured by activity level and convalescence days following surgery. Late (>6 months) functional outcomes were measured as ambulation, independent living, and employment status pre- and postoperatively.

RESULTS

Operative mortality for open repair was 5 (3.5%) compared to 1 (0.6%) after an endovascular procedure (p<0.05). The endovascular group had a shorter hospital stay (2.8+/-2.8 versus 8.3+/-4.5 days) and fewer skilled nursing requirements (0% versus 26%; p<0.001). Cumulative hospital utilization over 12 months was 3.8 days for endovascular patients and 13.8 days for open repair (p<0.001). Recovery time was 99.3+/-84.1 days (range 14-365) in conventionally treated patients and 32.1+/-43.5 days (range 7-180) in the stent-graft group (p<0.001). At 6 months, 43 (75%) open and 54 (95%) endovascular patients had full recovery (p<0.01). Activity levels decreased in 13 (23%) open and 3 (5%) endovascular patients after surgery (p<0.01). There were no differences in ambulation, independent living, or employment status before and after treatment.

CONCLUSIONS

Periprocedural survival following aneurysm repair is improved with endovascular grafting compared to open surgery, and recovery is more rapid, with a 78% reduction in total hospital days. Early functional outcomes are markedly improved with endovascular repair, while there is no difference in late functional outcomes between the procedures.
