Atherosclerosis and its complications are associated with high morbidity and mortality in the elderly. One of these complications is abdominal aortic aneurysm which may be prevented from rupturing if diagnosed early. Screening for aortic aneurysm was carried out in Jeddah, which is in the western region of Saudi Arabia, to identify the magnitude of this problem. Three groups were studied: patients with hypertension (n = 101), patients with peripheral vascular disease (n = 71) and a third group of controls (n = 220). The mean (range) age of the whole sample was 66.0 (60–80) years. Evidence of aortic aneurysm was found in seven participants: five in the peripheral vascular disease group (7.0%), one in the hypertensive group (1.0%) and one in the controls (0.5%). In view of the expected increase in the elderly population of Saudi Arabia, as a result of improvements in health care which have recently been achieved, it is expected that a similar increase in the incidence of abdominal aortic aneurysm may occur. Routine screening for abdominal aortic aneurysm in the elderly, especially in those with peripheral vascular disease, may be worthwhile. 相似文献

OBJECTIVE: Despite an increasing number of elective operations on abdominal aortic aneurysms (AAAs), the age- and sex-standardized mortality rate of ruptured AAA (RAAA) continues to increase. In the Pirkanmaa region, population 440,000, all aortic surgery is performed at Tampere University Hospital (TAUH). Procedures have been collected into the vascular registry. The purpose of this study was (1) to establish the incidence, modes of treatment, and mortality of RAAA in a defined geographic area; (2) to evaluate the prerupture history to determine if there are any ways to prevent rupture; and to make a forecast about the increase of RAAAs in the next decades. METHODS: Population and outcome data in the Pirkanmaa region and information on all patients who died of RAAA during 1990-1997 were provided by Statistics Finland. All operated RAAAs that underwent procedures during 1990 to 1999 were identified from the local vascular registry. To make a forecast for the next decades, an incidence of RAAA was calculated separately for each age group in 5-year intervals. RESULTS: From 1990 to 1997, 221 patients presented with RAAA. The mean incidence was 6.3/100,000 inhabitants. The incidence in the population over 65 years was 35.5/100,000. The total RAAA mortality was 76.9%. A total of 139 patients reached TAUH and 111 underwent emergency surgery. The overall hospital mortality in TAUH was 63.3%. The calculated annual number of RAAA will increase 49.6% in the next 2 decades, and the overall incidence will increase from 6.3 to 8.9/100,000 inhabitants. According to the vascular registry, 166 patients were operated on for RAAA during 1990 to 1999 in TAUH. The 30-day mortality was 50.6%. A minority of the patients (n = 18, 10.8%) had a previously documented AAA. The median diameter at the time of rupture was 7 cm. Seven (5.0%) men and six (24.0%) women had a diameter of less than 5.5 cm. CONCLUSION: The incidence of RAAA in the Pirkanmaa region in 1990s was the Finnish average. In the next two decades, the number of individuals with RAAA will increase significantly. One quarter of women had a diameter of AAA at the time of rupture that was under the current threshold indicator for elective operation. 相似文献

In order to evaluate the feasibility of a selective screening programme for abdominal aortic aneurysm (AAA) within an urban setting and assess its impact on the expected increase in workload for the local hospital(s), a population based, prospective study was performed. A total of 4823 men aged 65 years were invited for ultrasound examination of the abdominal aorta between January 1993 and April 1997 as part of a general practice-based aneurysm screening programme covering two districts with a general hospital each. All examinations were carried out by senior radiographers using a portable B mode grey scale machine and a 3.5 MHz curvi-linear array probe. Patients with a maximum aortic diameter of over 3 cm were annually recalled, those with over 4 cm were referred to hospital for an out-patient's appointment. Those with AAA greater than 5 cm were considered for surgery. Of those approached, 3497 (72.5%) took part in the study, 1206 (25%) did not attend and 120 (2.5%) were excluded by their general practitioners (GPs) on medical grounds. Of the men taking part, 3130 (89.5%) had an aortic diameter equal to or less than 2.5 cm, 196 (5.6%) between 2.6 and 3.0 cm, and 171 (4.9%) had aortic diameters greater than 3 cm--29 of whom had AAA greater than 5 cm with a mean diameter of 6.0 cm (range 5.1-9.0 cm). Of 127 men with an initial diameter of 3.1-4.0 cm (mean progression in size of 2.3 mm/year), 22 enlarged to > 4 cm and 3 to > 5 cm. Of 24 men with an initial diameter of 4.1-5.0 cm, 6 enlarged to > 5 cm. Some 69 (2%) patients were referred to hospital requiring a total of 125 consultations (1.8 consultations per patient); 21 underwent surgery and one died from rupture whilst awaiting surgery. Five patients refused their operation and two failed to attend the clinic (all > 5 cm) but remain well to date. No patient died following surgery. We conclude that, screening for AAA in men at age 65 years within an urban setting is feasible and well received by patients and GPs. Screening does not lead to a huge increase in terms of outpatient appointments and operations for AAA. 相似文献

Background
Based on randomized, population-based screening protocols, a single ultrasound examination reduces mortality from an abdominal aortic aneurysm (AAA) by facilitating elective surgical intervention before rupture. Ultrasound screening is accurate, noninvasive, inexpensive, and cost effective. By using a comprehensive electronic medical record, we inquired whether an age-prompted clinical reminder would facilitate the detection of AAA.Methods
The AAA risk screen was installed in May 2007 via a computerized patient record system prompt for male veterans ages 65 to 75 who ever smoked. This abbreviated ultrasound examination uses a 3.5- to 4-MHz scan head, measures anteroposterior and transverse planes, and reports the largest infrarenal aortic diameter.Results
Of 1437 examinations there were 73 AAAs of 3.0-cm diameter or larger (5.1%); 33 AAAs of 4.0-cm diameter or larger (2.3%); 15 AAAs of 5.0-cm diameter or larger (1.0%); and 11 AAAs of 5.5-cm diameter or larger (.77%). Fifty (68%) received counseling for abnormal findings.Conclusions
Recognition of newly diagnosed AAA compared favorably with that of previous screening studies. Electronic clinical reminders identify undiagnosed, life-threatening AAAs before rupture. Immediate counseling is available in the vascular setting. 相似文献8.

The level of blood lipids and apolipoproteins in subjects being screened for abdominal aortic aneurysms have been investigated. As part of an ultrasound screening programme in a population of 65- to 75-year-olds, blood samples were collected from 1460 of 1504 subjects with a normal aorta (97.1%) and 69 of 70 patients with an abdominal aortic aneurysm >29 mm (99%). Samples were also taken from 22 of 27 patients (81%) with an ectatic aorta (26–29 mm). Total cholesterol, HDL-cholesterol, LDL-cholesterol, Apo-AI and Apo-B levels were significantly higher in women than in men (P < 0.01). Levels of HDL-cholesterol and Apo-AI were significantly lower in patients with an abdominal aortic aneurysm than in normal subjects (P < 0.001). The mean (s.d.) body mass index was 25.1 (3.9) in women and 25.5(3.2) in men with aneurysms and not significantly greater than that of normal subjects (25.2(3.61) and 25.2(3.38) respectively).

Screening for abdominal aortic aneurysm and occlusive peripheral vascular disease in Japanese residents 总被引:1,自引:0,他引:1
Hiroyuki Takei Susumu Ishikawa Akio Otaki Kazuhiro Sakata Masahiro Aizaki Yasushi Sato Masao Suzuki Toshikazu Ishikita Yuichi Iino Takao Yokoe Yasuo Morishita 《Surgery today》1995,25(7):608-611
To evaluate the prevalence of abdominal aortic aneurysm (AAA) and occlusive peripheral vascular disease (PVD) in Japanese residents, and to examine the correlations between these diseases and the risk factors of atherosclerosis, 348 residents of a village in central Japan aged between 60 and 79 years were screened. The screening for AAA was performed using ultrasonography (US) and that for PVD was performed by palpation and Doppler US. No AAA was found, and a right common iliac arterial aneurysm was detected in a 79-year-old man (0.3%). The mean diameter of the infrarenal abdominal aorta was 18.7 mm and an abdominal aorta of 25 mm or greater in diameter was seen in 16 participants (4.6%), all of whom need to be followed up. PVD was suspected in two patients (0.6%) with a low ankle brachial pressure index. Of a total of five patients diagnosed or suspected of having a common iliac arterial aneurysm or PVD, four (80%) had at least one risk factor for atherosclerosis. Thus, we conclude that Japanese residents with risk factors predisposing them to atherosclerosis such as hypertension, obesity, abnormal serum lipid levels, and a history of smoking should be selectively screened for AAA and PVD due to the low prevalence of these diseases and from the viewpoint of cost-effectiveness. 相似文献
