Selective coronary angiography to determine the prevalence of coronary artery disease (CAD) has been performed in patients with abdominal aortic aneurysm (AAA). Thirty patients in this series consisted of 26 men and 4 women with an age range of 48-87 years (mean +/- SD: 67.5 +/- 8.2 years). As the atherosclerotic risk factors, cigarette smoking was present in 19 patients (63.3%), hypertension was in 18 (60%), hypercholesteremia was in 10 (33.3%), and diabetes mellitus was in 2 (6.7%). Cerebral vascular disease was present in 11 patients (36.7%). Regarding CAD, angina pectoris or old myocardial infarction was found in 9 patients (30%), and abnormal electrocardiography (ECG) was in 16 patients (53.3%). Coronary angiography prior to operation of AAA was performed to 22 patients (73.3%), and 15 patients (68.2%) among them had significant coronary artery stenosis, and 9 patients underwent myocardial revascularization (4 CABG, 5 PTCA). CAD was frequently complicated both in patients without symptoms or ECG abnormalities and in less than 65-year patients. In order to prevent fatal myocardial infarction, we recommend routine coronary angiography to patients with AAA. And if necessary, myocardial revascularization must be indicated prior to aneurysmectomy. 相似文献

OBJECTIVE: In Japan, the incidence of both colorectal carcinoma and vascular disease is increasing. We screened preoperative patients with abdominal aortic aneurysm (AAA) or peripheral artery disease (PAD) for colorectal cancer. DESIGN OF STUDY: This study was retrospective and cross-sectional. MATERIALS: The subjects were 492 patients admitted for elective surgery of AAA or PAD. METHODS: The patients underwent immunochemical faecal occult blood tests (FOBT) before operation, and those with positive results underwent investigations for colorectal neoplasm. We compared the results with that of screening programmes performed on the general population. RESULTS: Of the 408 patients that underwent FOBT, 104 (25.5%) were positive. After colonoscopy, six (1.5%) had colorectal carcinoma and 16 (3.9%) had advanced adenoma. These values were several folds higher than that for the general population in Japan. CONCLUSIONS: Patients with AAA or PAD carry a high risk for colorectal neoplasm. 相似文献

Prevalence of abdominal aortic aneurysm in patients with occlusive peripheral vascular disease 总被引:2,自引:0,他引:2
Over a 1-year period, 242 patients with peripheral vascular disease underwent abdominal ultrasonography to detect the presence of an abdominal aortic aneurysm. In 34 (14 per cent) an abdominal aortic aneurysm was found; half of these aneurysms were greater than 4 cm in diameter. In addition, 16 patients had ectatic aortas. Abdominal aortic aneurysms were more common in men than in women (17 versus 8 per cent). Patients with claudication were as likely to have an abdominal aortic aneurysm as those with rest pain or gangrene. The presence of aortoiliac occlusive disease increased the chance of an aneurysm being present (P less than 0.02). Patients with occlusive peripheral vascular disease are a high-risk group with regard to the development of an abdominal aortic aneurysm. Patients with proximal occlusive disease represent a subgroup at even higher risk. 相似文献

Background: The Asian population is believed to have lower incidence of abdominal aortic aneurysm (AAA), and hence, the benefit of screening is uncertain. The size of native aorta in Asians, which shall affect the definition of AAA, has also never been reported. Our study investigated the prevalence of AAA and the infra‐renal aortic diameter (AD) in Chinese patients with severe coronary artery disease. Methods: This is a prospective observational study of infra‐renal aortic size for patients who had coronary artery bypass surgery by ultrasound. The patients' demographics, important co‐morbidities and maximum AD were recorded. Results: The study included 624 consecutive Chinese patients (mean age = 63.2 years). The mean maximum infra‐renal AD was 17.5 mm for men and 14.8 mm for women. The presence of AAA was defined as maximum AD greater than 30 mm. The result was also compared with an alternate definition that defines AAA as maximum AD of greater than 1.5 times of the group's mean. Eleven patients had an AD greater than 30 mm, and the prevalence of AAA was only 1.8%. With AAA defined as maximum AD of 1.5 times greater than the group's mean, 19 patients had AAA. The prevalence of AAA in this high‐risk group would become 3% overall. Conclusion: The prevalence of AAA in Chinese patients was low, and the result did not support routine screening. The smaller mean infra‐renal AD in Chinese merits validation by large‐scale study and consideration when deciding threshold for small AAA repair in our locality. 相似文献

OBJECTIVES: Complication due to coronary artery disease (CAD) is a major cause of mortality in the surgical treatment of abdominal aortic aneurysm (AAA). The purpose was to show 1) the incidence of patients who required coronary artery bypass grafting (CABG), and 2) risk factors for the necessity of CABG in patients with AAA. METHODS: Subjects were consecutive 159 patients (132 males and 27 females) undergoing elective repair of non-ruptured AAA between May 1993 and March 2002. Most patients (n=145) underwent routine preoperative coronary angiography (CAG) and received coronary revascularization when necessary. Clinical atherosclerotic risk factors were subjected to univariate and multivariate analysis to determine predictors for the necessity of CABG. RESULTS: Of 43 patients (27.0%) with significant coronary stenosis, 7 patients (4.4%) underwent CABG concomitantly (n=1) or prior to the AAA repair (n=6) in the same admission. Other patients received percutaneous transluminal coronary angioplasty (PTCA) (n=14) and isolated medical treatment (n=22). Overall mortality of 159 patients undergoing AAA repair was 2.5% and there were no deaths in 7 patients undergoing CABG. Univariate and multivariate analysis indicated only the history of angina as significant for the necessity of CABG in patients with AAA. Of 155 survivors, 5 patients underwent CABG later in the follow-up period. CONCLUSIONS: The incidence of patients who required CABG in the treatment of AAA was 4.4% in our institute. It was difficult to predict the necessity of CABG without conducting CAG in patients with asymptomatic myocardial ischemia. These results may justify the routine enforcement of preoperative CAG in patients with AAA. 相似文献

Coronary artery disease (CAD) is associated with abdominal aortic aneurysm in greater than 60% of cases. CAD continues to affect postoperative complication rates. Half of the deaths that follow resection of abdominal aortic aneurysms are due to perioperative myocardial infarctions. On evaluation for surgical resection of an abdominal aortic aneurysm, six patients were found to have significant CAD. Each underwent coronary artery bypass surgery prior to elective resection of the aneurysm. No deaths or myocardial infarctions occurred following any of the procedures. We restrict our indications for coronary angiography to the evaluation of patients with unstable angina (pain at rest or after minimal exertion) in whom noninvasive studies reveal evidence of CAD, and for patients who are unresponsive to medical management. 相似文献

The chief cause of operative mortality after abdominal aortic aneurysm (AAA) repair is myocardial infarction. For this reason, routine coronary angiography followed by prophylactic coronary artery bypass grafting (CABG) prior to AAA repair has been recommended by some surgeons. We report here the results of the selective use of a combined operation. Two hundred twenty-seven patients had elective or emergency repair of nonruptured AAA on our service from 1972 to 1983. Prior to surgery, all patients underwent careful clinical evaluation for the presence of coronary artery disease (CAD) and were classified into the following: group I (n = 121), no clinical evidence of CAD, 53%; group II (n = 96), clinical evidence of stable CAD, symptomatic or asymptomatic, 42%; group III (n = 10), unstable CAD, five per cent; Group IIIa (n = 4), asymptomatic AAA; and group IIIb (n = 6), symptomatic AAA. Seven patients ultimately assigned to group II underwent stress electrocardiogram (ECG) and eight group II patients had coronary angiography before surgery. All patients in groups I and II underwent elective or urgent repair of their AAA without CABG. Prior to surgery, these patients were managed with placement of a pulmonary artery catheter and incremental volume loading to construct a left ventricular performance curve as a guide to surgical fluid replacement. All were carefully monitored for at least 48 hours after surgery in an intensive care unit. Four patients (group IIIa) with unstable CAD and asymptomatic AAA underwent CABG followed by elective AAA repair within six months. Six patients (group IIIb) with unstable CAD and symptomatic AAA underwent combined open heart surgery (CABG and, in one patient, valve replacement) and AAA repair as a single operation. There was no operative mortality in group III patients. Thirty-day operative mortality for the entire group of 227 patients was 1.3% (three deaths), with only one death from a myocardial infarction (0.4%). While there is clearly a high incidence of CAD in patients with AAA, the present results indicate that these individuals can be managed with low risk by a selective approach based upon clinical assessment of their CAD. Our experience further demonstrates that patients with unstable CAD and symptomatic AAA may have both lesions safely repaired as a single operative procedure. 相似文献

Gallstones were detected in 42 of 865 patients with abdominal aortic aneurysm (4.9%). Eighteen patients underwent concomitant aneurysm resection and cholecystectomy. Eleven patients had aneurysmectomy without cholecystectomy. Thirteen patients underwent cholecystectomy alone. There were no significant increases in operative mortality, duration of operation, or length of hospital stay when cholecystectomy was added to aneurysm resection. However, there was one instance of prosthetic infection which occurred in a patient who did not have his graft retroperitonealized prior to cholecystectomy, and who also underwent gastrostomy and drainage of the liver bed. There have been no graft complications in the remaining 17 consecutive patients who had their graft retroperitonealized prior to cholecystectomy. Nine of 11 patients who underwent aneurysmectomy without cholecystectomy experienced an episode of acute cholecystitis during a mean follow-up period of 2.9 years. Two of these episodes occurred in the immediate postoperative period and one patient died of biliary sepsis. On the basis of these findings, concomitant aneurysmectomy and cholecystectomy is advised in those patients with cholelithiasis undergoing aortic aneurysm resection providing no contraindications exist. 相似文献

BACKGROUND: Isolated iliac artery aneurysms (IAA) in patients with or without previous abdominal aortic aneurysm (AAA) repair are rare. We wanted to compare the presentation, distribution, treatment, outcome and patterns of subsequent aneurysm formation in these patients. METHODS: We retrospectively reviewed patients with isolated IAA over a 10-year period. Patients with primary isolated IAA (group 1) were compared with patients who presented with IAA after previous AAA repair (group 2). RESULTS: There were 23 patients in each group. Demographics and comorbidities were similar. No aneurysms were detected outside of the iliac system in group 1; 22% of patients in group 2 had other aneurysms. The mean time after AAA repair to IAA diagnosis was 8.8 +/- 3.2 years for operated on patients. The in-hospital mortality was 0% for elective cases and 50% for emergency cases for both groups. Three patients in group 2 (13%) developed new aneurysms during follow-up, whereas the only new aneurysm in group 1 was a contralateral IAA. CONCLUSIONS: Patients with new IAA after AAA repair have a greater tendency to develop further aneurysms in other sites, synchronously or metachronously. The time to detection of new IAA after AAA repair is at least 5 years in most cases. In both groups, a quarter to a third of patients present with rupture, with a resultant mortality of 30% to 50%, whereas those operated on electively have minimal morbidity and almost no mortality. 相似文献

BACKGROUND: Patients undergoing abdominal aortic aneurysm (AAA) surgery are at increased risk of perioperative cardiovascular complications due to underlying coronary artery disease (CAD). We determined retrospectively the incidence of CAD and the influence of coronary revascularization and perioperative cardiovascular complications in patients for AAA surgery. METHODS: Routine coronary angiography (CAG) was performed in 159 patients prior to elective AAA surgery to estimate the presence of CAD. To compare risk factors and perioperative cardiovascular complications the patients were divided at the time of CAG into three groups: previously diagnosed CAD, newly diagnosed CAD and non-CAD. RESULTS: Preoperative CAG found 129 patients (81%) with CAD. Among newly diagnosed patients 82% were asymptomatic of CAD. Forty-four patients (28%) underwent coronary revascularization (17 percutaneous coronary intervention, 3 preoperative coronary artery bypass grafting, and 24 combined coronary artery bypass grafting). Perioperative cardiac complications occurred in 35 patients (22%). No significant difference was found among the three groups in the incidence of perioperative cardiovascular complications. Two patients with severe CAD not treated with coronary revascularization died of cardiac events. CONCLUSIONS: Perioperative management and coronary revascularization should be carried out with more cautions in AAA patients to reduce the incidence of cardiovascular complications after AAA surgery. 相似文献

BACKGROUND: The technique of hypotensive resuscitation in haemorrhagic shock involves resuscitation to below normotensive blood pressures achieving the minimum perfusion pressure that will adequately perfuse vital organs until definitive arrest of haemorrhage. AIM: To summarise the evidence for the use of hypotensive resuscitation in patients with uncontrolled haemorrhagic shock and ruptured abdominal aortic aneurysm (AAA). METHODS: A MEDLINE (1966-2004) and Cochrane library search for articles relating to hypotensive resuscitation was undertaken; see text for further details. RESULTS: Several animal studies exist using an abdominal aortotomy model of ruptured AAA. These have demonstrated improved tissue perfusion, decreased blood loss and improved survival associated with hypotensive resuscitation compared with aggressive resuscitation. There are several human studies advocating delayed rather than immediate resuscitation in trauma patients but careful review of the literature reveals no prospective studies of hypotensive resuscitation in patients with ruptured AAA. CONCLUSIONS: Animal studies demonstrate superiority of hypotensive resuscitation over aggressive resuscitation but further research is required to assess its efficacy in patients with ruptured AAA. 相似文献

Patients undergoing abdominal aortic aneurysm (AAA) are at increased risk for cardiovascular complications such as cardiac death and nonfatal myocardial infarction. Dobutamine stress echocardiography is an established, cost-effective technique for the detection of coronary artery disease (CAD). This review will focus on the additional prognostic value of dobutamine stress echocardiography for perioperative and late prognosis in patients with AAA and CAD. 相似文献

OBJECTIVE: Surgical treatment of thoracic aortic surgery in patients with coronary artery disease was investigated. METHODS: Between 1990 and April 2003, 330 patients underwent elective thoracic aortic surgery. Fifty-six patients who underwent aortic root reconstruction were excluded and 274 patients were examined. Fifty-four (20%) patients showed concomitant coronary artery disease. Ten had undergone coronary revascularization previously; and 3 underwent coronary revascularization [2 coronary artery bypass grafting (CABG), 1 percutaneous transluminal coronary angioplasty (PTCA)] before aortic surgery. Twenty-three patients underwent elective CABG simultaneously and 2 patients had additional coronary artery bypass because of cardiac ischemia during operation. The number of patients who underwent thoracic aortic surgery including Asc Ao+AVR was 2, hemi arch 1, total arch 15, distal arch 5, distal arch+LV aneurysmectomy 1, and thoracoabdominal Ao 1. Two patients underwent coronary revascularization with arterial grafts and the others with SVG grafts. RESULTS: There was one hospital death (4%). In patients without coronary bypass, 2 patients suffered cardiac ischemic events. CONCLUSION: Our thoracic aortic operations with concomitant CABG using SVG were overall successful. Our current strategies for thoracic aortic surgery in patients with concomitant coronary artery disease include conducting a dipyridamole myocardial perfusion-imaging test first in patients not at risk of coronary artery disease, and if the test is positive, coronary angiography is performed and aggressive coronary revascularization is conducted where possible. 相似文献

The role of coronary artery disease in complications of abdominal aortic aneurysm surgery 总被引:2,自引:0,他引:2

Coronary artery disease (CAD) is a major cause of morbidity and mortality after elective surgical repair of abdominal aortic aneurysm (AAA). The aim of this study was to determine the relationship between the extent of CAD observed in coronary angiograms (more than 50% stenosis) and the frequency of postoperative myocardial ischemic complications in a consecutive series of 84 patients who underwent elective AAA repair. Ninety-four percent of the patients with clinical evidence of CAD had significant disease as observed in coronary angiograms and eight patients had left main CAD. Seventy-two patients underwent AAA repair with a mortality rate of 1.4%; five patients had preliminary myocardial revascularization, and AAA surgery was not recommended for four patients because of severe cardiac disease. Postoperative myocardial ischemic complications occurred in 13.4% of the patients who had undergone surgery--almost exclusively in patients with clinical evidence of CAD. Both myocardial ischemia and preoperative intervention were more frequent in patients with double- or triple-vessel disease than in patients with less extensive disease. Patients with symptoms and with double- or triple-vessel CAD have a high risk of developing myocardial ischemia after AAA surgery. Preliminary myocardial revascularization may be beneficial in this group of patients. 相似文献

AIMS: Renal dysfunction occurs occasionally after the repair of abdominal aortic aneurysm (AAA), and preoperative renal function is considered as one of the potential causes. The present study was designed to evaluate and compare renal function and risk factors of AAA patients with those of hypertensive patients. METHODS: We prospectively examined 95 patients with AAA and 72 patients with essential hypertension (HT) without other cardiovascular diseases (CVD). Renal function, urinary albumin excretion (UAE) and renal scintigraphy were compared. Kidney size was calculated using ultrasonography. RESULTS: Serum creatinine and creatinine clearance in AAA patients was worse than in HT patients. Smoking status was more apparent in AAA patients. Renal artery stenosis occurred in 8 patients with AAA. Renal scintigraphy showed normal function in 19%, hypofunction in 69% and severe dysfunction in 12% of the AAA patients, and normal function in 42% and hypofunction in 58% of the HT patients (p < 0.0001). Multivariate linear regression analysis showed that renal function was related to age, UAE, CVD, smoking status and kidney size for all patients, UAE, CVD, smoking status and kidney size for AAA patients, and age and kidney size for HT patients. CONCLUSION: Renal function of AAA patients was worse than HT patients without other CVD. The risk factors for renal dysfunction were different between AAA and HT patients. These preoperative conditions may relate to the postoperative renal dysfunction seen in AAA patients. 相似文献

Factors determining the outcome for patients with abdominal aortic aneurysm (AAA) were analysed in a retrospective population-based study of 187 consecutively diagnosed AAAs at one hospital during a 9-year period. All aneurysms were diagnosed by ultrasound, and those cases that were not primarily operated upon, were followed by repeat ultrasound examinations. An expansion rate of more than 0.4 cm/year was seen in 27% of the aneurysms and a tendency towards a higher rate of expansion could be seen with larger lesions. The overall cumulative rupture rate was 12% at 5 years. For patients with small (less than 5 cm) aneurysms it was 2.5% at 7 years, and no aneurysm could definitively be shown to be smaller than 5 cm at the time of rupture. The rupture risk was significantly higher (28% at 3 years) for larger aneurysms (greater than or equal to 5 cm). The only reliable predictor for rupture was aneurysm size. The overall cumulative survival was 51% at 5 years. Patients with large aneurysms did not have a significantly shorter survival although a tendency for this to be the case was found. There was a significant difference between the proportion of deaths caused by aneurysm rupture in patients with small aneurysms when compared to those with large aneurysms, 5.5 and 53%, respectively. The expansion rate for AAA was highly individual and aneurysm diameter was the only recognisable predictor of rupture. The rupture rate for AAAs smaller than 5 cm was lower than previously reported. 相似文献

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
