Quality of life, symptoms and treatment satisfaction in patients with aortic aneurysm using new abdominal aortic aneurysm-specific patient-reported outcome measures.

BACKGROUND: The aim of this study was to present preliminary data on quality of life (QoL), symptoms and treatment satisfaction gathered using three new abdominal aortic aneurysm (AAA)-specific patient-reported outcome measures (PROMs). METHODS: Patients with AAA were recruited from five National Health Service Trusts to complete the three new PROMs: the AneurysmDQoL, AneurysmSRQ and AneurysmTSQ. Patients were either under surveillance or had undergone AAA repair (open or endovascular) during the preceding 24 months. Data were initially collected as part of a study assessing the psychometric properties of the new measures, before being used in the observational analysis of outcomes presented here. RESULTS: Results, although largely non-significant, showed interesting trends. The impact of AAA repair on QoL appeared to worsen progressively after open repair (OR) and improve progressively after endovascular aneurysm repair (EVAR). Conversely, symptoms seemed to become progressively worse after EVAR and progressively better after OR. Information and understanding were key sources of dissatisfaction before the intervention, whereas postoperative dissatisfaction was related to bother from symptoms, follow-up and feedback about scan results. CONCLUSION: Although a larger, prospective data set is necessary to explore outcomes more fully with the new AAA-specific PROMs, the observational data presented here suggest there may be clinically important differences in the symptoms, impact on QoL and treatment satisfaction associated with OR and EVAR.

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.

The shortfall in long-term survival of patients with repaired thoracic or abdominal aortic aneurysms: retrospective case-control analysis of hospital episode statistics.

OBJECTIVE: To report the contemporary life expectancy of patients undergoing abdominal (AAA) or thoracic aortic aneurysm (TAA) repair in England, relative to a healthy control population. METHODS: A retrospective observational case-control study was carried out of Hospital Episode Statistics (HES) data, an administrative dataset covering the entire English National Health Service. Patients undergoing elective repair of an abdominal or thoracic aortic aneurysm in an English NHS hospital between April 2006 and March 2011 were included. Outcome measures were 5-year all-cause mortality (in- and out-of-hospital) and adverse cardiovascular events (myocardial infarction, stroke, emergency amputation or limb revascularisation). RESULTS: 19,505 AAA and 730 TAA repairs were identified, with 75,260 and 2,721 control participants, respectively, and 27.5 (1.0-60.0) months' median (range) follow-up. Five-year survival was 67.4% for AAA against 81.1% for control participants, and 65.3% for TAA against 89.1% for control participants (p < .001). Freedom from adverse cardiovascular events was 86.1% for AAA against 93% for control participants and 89.1% for TAA against 94.4% for control participants (p < .001). CONCLUSION: Long-term survival remains poor after aneurysm repair and adverse cardiovascular events are common relative to the wider population. Further research is required to characterise and optimise cardiovascular risk prevention in patients with aortic aneurysms.

Measures of health-related quality of life in diabetes-related foot disease: a systematic review.

AIMS/HYPOTHESIS: Patient-reported outcome measures (PROMs) are increasingly used as key performance indicators in chronic illness. We sought to review the value of these tools in assessing health-related quality of life (HRQOL) in patients with diabetes-related foot disease and identify the impact of each foot problem on life quality. METHODS: A systematic review of literature on HRQOL PROMs in diabetes-related foot disease was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The quality of eligible studies was evaluated within pre-existing criteria. RESULTS: 53 studies written between 1995 and 2010 met the inclusion criteria. A variety of HRQOL PROMs were used. Disease-specific tools were better than generic at quantifying temporal changes in life quality and showed greater sensitivity to ulcer/neuropathic severity. No studies have simultaneously evaluated disease-specific tools. Generic and utility HRQOL PROMs are frequently used as secondary outcome measures in randomised trials and cost-utility analysis. HRQOL is depressed in diabetes, further impaired by the presence of foot disease. Ulcer healing is associated with improvements in HRQOL. Patients with active ulceration report poorer HRQOL than those whom have undergone successful minor lower extremity amputation (LEA) but there is a paucity of quality data on HRQOL outcomes for diabetes-related LEA. CONCLUSIONS/INTERPRETATION: No one PROM was identified as a 'gold standard' for assessing HRQOL in diabetes-related foot disease. Specific areas for further development include the most valid HRQOL PROM with disease-specific content; HRQOL outcomes in minor and major amputations and the role of HRQOL tools in routine clinical care.

Endofibrosis and kinking of the iliac arteries in athletes: a systematic review.

INTRODUCTION: Kinking and endofibrosis of the iliac arteries are uncommon and poorly recognized conditions affecting young endurance athletes. Deformation or progressive stenosis of the iliac artery may reduce blood flow to the lower limb and adversely affect performance. The aim of this review was to examine the existing literature relating to these flow-limiting phenomena and identify a clear, unifying strategy for the assessment and management of affected patients. METHODS: A systematic review of the literature was performed. A comprehensive search was carried out using Medline, Embase and The Cochrane Database to identify relevant articles published between 1950 and 2011 (last search date 05/08/2011). This search (and additional bibliography review) identified 413 articles, of which 367 were excluded. 46 articles were then studied in detail. Methodological quality of studies was assessed according to Scottish Intercollegiate Guideline Network criteria. RESULTS: Focussed history and examination can successfully identify nearly 80% of patients with iliac flow limitation. However, both provocative exercise tests and detailed imaging are also necessary to identify those in need of intervention and establish most appropriate treatment. Provocative exercise tests and duplex imaging can then be used to confirm flow limitation before detailed assessment of abnormal anatomy with MRA and DSA. These multiple imaging modalities are necessary to identify those most likely to benefit from surgery and clarify whether each patient should undergo arterial release, vessel shortening, endofibrosectomy or interposition grafting. CONCLUSION: We present a systematic review of the literature together with a proposed algorithm for diagnosis and management of these iliac flow limitations in endurance athletes.

Operator-controlled imaging significantly reduces radiation exposure during EVAR.

INTRODUCTION: Adoption of endovascular aneurysm repair (EVAR) has led to significant reductions in the short-term morbidity and mortality associated with abdominal aortic aneurysm (AAA) repair. However, EVAR may expose both patient and interventionalist to potentially harmful levels of radiation, particularly as more complex procedures are undertaken. The aim of this study was to assess whether changing from radiographer-controlled imaging to a system of operator-controlled imaging (OCI) would influence radiation exposure, screening time or contrast dose during EVAR. METHOD: Retrospective analysis identified patients that had undergone elective EVAR for infra-renal AAA before or after the change to operator-controlled imaging. Data were collected for radiation dose (measured as dose area product; DAP), screening time, total delivered contrast volume and operative duration. Data were also collected for maximum aneurysm diameter, patient age, gender and body mass index. RESULTS: 122 patients underwent EVAR for infra-renal AAA at a single centre between January 2011 and December 2011. 57 of these were prior to installation of OCI and 65 after installation. Median DAP was significantly lower after installation of OCI (4.9 mGy m(2); range 1.25-13.3) than it had been before installation (6.9 mGy m(2); range 1.91-95.0) (p = 0.005). Median screening times before and after installation of OCI were 20.0 min and 16.2 min respectively (p = 0.027) and median contrast volumes before and after the change to OCI were 100 ml and 90 ml respectively (p = 0.21). CONCLUSION: Introduction of operator-controlled imaging can significantly reduce radiation exposure during EVAR, with particular reduction in the number of 'higher-dose' cases.

Prognostic significance of circulating tumour cells following surgical resection of colorectal cancers: a systematic review.

BACKGROUND: The role of adjuvant chemotherapy after resection of colorectal cancers (CRCs) is well understood for patients with stage-I or stage-III disease. Its efficacy for those with stage-II disease remains much less clear. Many investigators have sought to identify prognostic markers that might clarify which patients have the highest risk of recurrence and would, therefore, be most likely to benefit from chemotherapy. This systematic review examines evidence for the use of peripherally sampled, circulating tumour cells (CTCs) as such a prognostic marker. METHODS: A comprehensive literature search was used to identify studies reporting on the significance of CTCs in the postoperative blood of CRC patients. RESULTS: Fourteen studies satisfied the inclusion criteria. Six of the nine studies that took blood samples 24 h or more postoperatively found detection of postoperative CTCs to be an independent predictor of cancer recurrence. CONCLUSION: The presence of CTCs in peripheral blood at least 24 h after resection of CRCs is an independent prognostic marker of recurrence. Further studies are needed to clarify the optimal time point for blood sampling and determine the benefit of chemotherapy in CTC-positive patients with stage-II disease.

Small bowel obstruction and perforation due to a displaced spiral tacker: a rare complication of laparoscopic inguinal hernia repair.

Laparoscopic techniques are now commonly used for the repair of inguinal hernias, since they offer rapid postoperative recovery and low complication rates. These methods usually involve the use of sutures, staples or titanium spiral tackers for safe, secure mesh fixation. We report a rare case of obstruction and perforation of the small bowel resulting from a band adhesion caused by a displaced spiral tacker.

Hyperbaric oxygen and the reflex sympathetic dystrophy syndrome: a case report.

A patient suffering from acute smoke inhalation also had a long medical history that included reflex sympathetic dystrophy syndrome of the left foot and ankle. The entire foot and ankle were tender and cool to palpation; range of motion was severely reduced. She was referred for hyperbaric oxygen therapy, and 15 min into the the first treatment (46 min at 60 fsw) she reported a lessening of the pain in her foot; moreover, the foot was less cyanotic and warmer to the touch. Subsequent treatments continued to improve her conditions and for longer periods of time.

Traumatic arterial spasm causing transient limb ischaemia: a genuine clinical entity.

Traumatic arterial spasm is a phenomenon that has long been questioned by clinicians. Indeed, some would argue that surgical exploration is mandatory whenever there are signs of distal ischaemia following limb trauma. We present a case of angiographically demonstrated tibial artery spasm following gunshot injury. Exploration was unnecessary and distal perfusion was reestablished spontaneously. This case demonstrates the existence of traumatic arterial spasm as a genuine clinical entity and suggests that immediate surgical exploration may not be necessary in all cases.
