[Stenting of uncomplicated type B aortic dissection].

Conservative treatment of uncomplicated type B aortic dissection is associated with low short-term mortality. However long-term mortality and complication rates are high, suggesting the need for more aggressive treatment. Studies suggest that combining medical treatment with thoracic endovascular aortic repair (TEVAR) is associated with a better prognosis.

Perigraft seroma penetrating the aortic sac and rupturing into the intraperitoneal cavity.

We present a case of a 66-year-old woman who developed perigraft seroma after having undergone elective, open abdominal aortic aneurysm repair with a polytetrafluoroethylene graft 5 years previously. One year after graft implantation, she started to suffer from abdominal discomfort and was therefore offered surgical intervention, which she declined owing to the fear of postoperative complications. Instead, an observational strategy was used.

Current management of inguinal false aneurysms.

False aneurysms are formed as a result of bleeding causing a hematoma to compress the surrounding tissue. The majority of false aneurysms presenting to the vascular surgeon are caused by iatrogenic injury to an artery. Although anastomotic failure occurs, a much higher number is caused by bleeding from puncture sites after percutaneous intervention.

Mycotic aneurysm caused by Burkholderia pseudomallei in a previously healthy returning traveller.

Burkholderia pseudomallei is a common cause of serious, difficult to treat infections in South-East Asia and Northern Australia, but is a rare imported pathogen in the USA and Europe. We report a case of a patient with a mycotic aneurysm caused by B. pseudomallei in a previously healthy returning traveller.

Femoral vein repair of arterial infections: technical tips to reduce procedure time.

Introduction: Success with the neoaortoiliac system (NAIS) bypass has previously been reported. Drawbacks to this procedure include prolonged operative times and significant morbidity. The aim of this study was to evaluate whether a 2-team approach in addition to a consistent anastomosis technique reduces the operative time of the NAIS procedure.

Intermittent roxithromycin for preventing progression of small abdominal aortic aneurysms: long-term results of a small clinical trial.

Background: Antibodies against Chlamydia pneumoniae are associated with an increased rate of expansion of small abdominal aortic aneurysms (AAAs). Short-term follow-up trials have shown a transient reduction AAA growth rate, in macrolide treated compared with placebo. Therefore we analysed the influence of intermittent, long-term roxithromycin treatment on AAA expansion and referral for surgery.

[What are the direct costs of an abdominal aortic aneurysm repair in a Danish hospital?].

Introduction: The aim of the study was to estimate the direct cost of an abdominal aortic aneurysm (AAA) repair and to validate it against the national Diagnostic Related Group (DRG) costs.

Material: Over a three-year period, between January 1996 and December 1998, a total of 100 men were selected at random from a series of 197 patients treated with open surgery for (AAA) at the Department of Vascular Surgery, Viborg Hospital.

Results: The total cost of an AAA operation without complications was estimated to be 70,000 DKK, compared to the DRG price of 79,000 DKK.

[Optimal interval screening and observation of abdominal aortic aneurysms].

Introduction: Screening and observation of abdominal aortic aneurysms (AAA) produce psychological stress. Consequently, safe and optimal intervals of rescreening and observation must be developed.

Randomized double-blind controlled trial of roxithromycin for prevention of abdominal aortic aneurysm expansion.

Background: Macrolide treatment has been reported to lower the risk of recurrent ischaemic heart disease. The influence of macrolides on the expansion rate of abdominal aortic aneurysms (AAAs) remains unknown. The aim was to investigate the effect of roxithromycin on the expansion rate of small AAAs.

Antibodies against Chlamydia pneumoniae predict the need for elective surgical intervention on small abdominal aortic aneurysms.

Objective: to compare the ability of two independent Chlamydia pneumoniae antibody tests to predict need for small abdominal aortic aneurysm (AAA) repair.

Five-year results of elastin and collagen markers as predictive tools in the management of small abdominal aortic aneurysms.

Objective: small abdominal aortic aneurysms (AAAs) do rupture and only half of AAAs above 5 cm would have ruptured unoperated. Furthermore, conservative treatment of AAAs may cause psychological side effects and impaired quality of life. To optimise the indication and time for operation for AAAs, we analysed whether serum elastin peptides (EP), procollagen-IIIN-terminal propeptide (PIIINP), and the initial AAA size could predict operation for AAAs in initially conservatively treated AAA.

The relationship between abdominal aortic aneurysm distensibility and serum markers of elastin and collagen metabolism.

Background: abdominal aortic aneurysm (AAA) distensibility may be an independent predictor of growth and rupture, possibly because it reflects changes in aortic wall structure and composition.

Aim: to determine whether AAA distensibility is related to circulating markers of elastin and collagen metabolism.

Methods: sixty-two male patients of median age (IQR) 68 (65-72) years with asymptomatic AAA of median (IQR) diameter 42 (37-45) mm were prospectively studied.

Apolipoprotein E genotype is associated with differential expansion rates of small abdominal aortic aneurysms.

Background: The common polymorphism of the apolipoprotein E (APOE) gene is associated with differential risk of atherosclerosis; the gene could be a candidate gene in abdominal aortic aneurysms (AAA).

Methods: APOE genotypes were determined in 57 men aged 65-73 years with a small AAA (30-50 mm). The patients were included in a population ultrasonographic screening programme and were followed with at least two examinations during an interval of 2-4.
