Reports on an association between body mass index and aortic disease, which remains controversial. This study investigated the association between body mass index and mortality from aortic disease.
METHODS
We conducted the Japan Collaborative Cohort Study, a prospective study of 103,972 Japanese men and women aged 40-79 years. Body mass index was calculated on the basis of self-reported height and weight, and the participants were followed up from 1988-89 through 2009. Sex-specific hazard ratios (95% confidence intervals) of mortality from aortic disease according to quintiles of body mass index were analyzed using the Cox proportional hazards model.
RESULTS
During the median 18.8 years of follow-up, we documented 139 deaths due to aortic aneurysm (including 51 thoracic and 74 abdominal aortic aneurysms) and 134 deaths due to aortic dissection. We observed positive associations of body mass index with mortality from aortic aneurysm among men: the multivariable hazard ratios (95% confidence intervals) for highest versus lowest quintiles of body mass index were 4.48 (2.10-9.58), P for trend <0.0001 for aortic aneurysm; 6.52 (1.33-32.02), P=0.005 for thoracic aortic aneurysm; 3.81 (1.39-10.49), P=0.01 for abdominal aortic aneurysm; and 2.71 (1.59-4.62), P=0.001 for total aortic disease. No association was found for aortic dissection. Among ever-smokers (men ≥ 90%) but not never-smokers (women ≥ 84%), an association between body mass index and aortic disease mortality was observed regardless of sex, which may explain the sex difference (P for sex-interaction=0.046).
CONCLUSIONS
We found a positive association between body mass index and mortality from aortic aneurysm among Japanese men and smokers.

Journal of the American College of... Feb 2022High plasma lipoprotein(a) and high body mass index are both causal risk factors for calcific aortic valve disease.
BACKGROUND
High plasma lipoprotein(a) and high body mass index are both causal risk factors for calcific aortic valve disease.
OBJECTIVES
This study sought to test the hypothesis that risk of calcific aortic valve disease is the highest when both plasma lipoprotein(a) and body mass index are extremely high.
METHODS
From the Copenhagen General Population Study, we used information on 69,988 randomly selected individuals recruited from 2003 to 2015 (median follow-up 7.4 years) to evaluate the association between high lipoprotein(a) and high body mass index with risk of calcific aortic valve disease.
RESULTS
Compared with individuals in the 1st to 49th percentiles for both lipoprotein(a) and body mass index, the multivariable adjusted HRs for calcific aortic valve disease were 1.6 (95% CI: 1.3-1.9) for the 50th to 89th percentiles of both (16% of all individuals) and 3.5 (95% CI: 2.5-5.1) for the 90th to 100th percentiles of both (1.1%) (P for interaction = 0.92). The 10-year absolute risk of calcific aortic valve disease increased with higher lipoprotein(a), body mass index, and age, and was higher in men than in women. For women and men 70-79 years of age with body mass index ≥30.0 kg/m, 10-year absolute risks were 5% and 8% for lipoprotein(a) ≤42 mg/dL (88 nmol/L), 7% and 11% for 42-79 mg/dL (89-169 nmol/L), and 9% and 14% for lipoprotein(a) ≥80 mg/dL (170 nmol/L), respectively.
CONCLUSIONS
Extremely high lipoprotein(a) levels and extremely high body mass index together conferred a 3.5-fold risk of calcific aortic valve disease. Ten-year absolute risk of calcific aortic valve disease by categories of lipoprotein(a) levels, body mass index, age, and sex ranged from 0.4% to 14%.

Review
While rare, abdominal aortic infections remain one of the most technically and emotionally challenging cases that a vascular surgeon may face. Secondary infections of either endovascular, or open aortic reconstructions range from 0.2% to 8%. Primary aortic infections are much more rare. Diagnosis can be elusive, depending upon the virulence of the causative microbes, and extent of the infection. Patients are often brittle, with immunocompromise and malnutrition prevalent in this patient population. The gold standard diagnostic test remains a computed tomographic angiogram. The mainstay of management requires vascular control, and wide debridement of all infected materials and revascularization. Multiple methods exist to reconstruct the vascular supply. The neo-aortoiliac system (NAIS) is attractive as it utilizes the patient's own femoral veins to reconstruct the vascular supply after the infection has been extirpated. The procedure is demanding upon the patient and surgeons alike. Also, the rarity of aortic infections limit experiences the literature to centers of excellence. However, the NAIS resists infection well, leaving the patient without any remaining foreign bodies. No further costs for conduit are incurred. Moreover, multiple experiences show excellent durability. While comparative effectiveness literature remains sparse, we believe the NAIS to be the optimal method of revascularization for select patients. In this article, we will review the use of NAIS for primary and secondary aortic infections. In particular, we will emphasize procedural details to help enable the reader to apply this procedure most effectively to their own patients.

AIMS
Aortic diseases (ADs), including aortic dissection, aortic aneurysm, and aortic rupture, are fatal, with extremely high mortality rates. A body shape index (ABSI), an anthropometric measure calculated as waist circumference adjusted by height and weight, improves the predictive capacity for mortality. However, whether ABSI is a risk factor for AD-related mortality in the general population remains unclear.
METHODS
We used a nationwide database of 630,842 individuals (aged 40-75 years) who participated in the annual "Specific Health Check and Guidance in Japan" between 2008 and 2010.
RESULTS
During the follow-up period of 3.8 years, 159 AD-related deaths occurred, including 105 aortic dissections and 54 aortic aneurysm ruptures. The subjects were divided into three groups based on ABSI tertiles. Kaplan-Meier analysis demonstrated that the 3 tertile (with the highest ABSI) had the greatest risk among the three groups. Multivariate Cox proportional hazard regression analysis demonstrated that ABSI was significantly associated with AD-related death after adjusting for confounding risk factors. Neither waist circumference nor body mass index consistently predicted AD-related death in the multivariate model. The prediction capacity was significantly improved by the addition of ABSI to the confounding risk factors.
CONCLUSIONS
We demonstrated for the first time that ABSI, a surrogate marker for abdominal visceral fat tissue, was associated with AD-related deaths in the general population, suggesting the importance of central adiposity in the development of AD.

BACKGROUND
In open thoracoabdominal aortic aneurysm (TAAA) repair, we have been performing vascular reconstruction under moderate to deep hypothermia and assisted circulation using simultaneous upper and lower body perfusion. This method is effective for protecting the spinal cord and the brain, heart, and abdominal organs and for avoiding lung damage.
METHODS
TAAA repair was performed under hypothermia at 20-28 °C in 18 cases (Crawford type I in 0 cases, type II in 5, type III in 3, type IV in 4, and Safi V in 6) between October 2014 and January 2023. Cardiopulmonary bypass was conducted by combined upper and lower body perfusion, with perfusion both via the femoral artery and either transapically or via the descending aorta or the left brachial artery.
RESULTS
The ischemic time for the artery of Adamkiewicz and the main segmental arteries was 40-124 min (75 ± 33 min). No spinal cord ischemic injury or brain or heart complications occurred. One patient with postoperative right renal artery occlusion and one with an infected aneurysm required tracheostomy, but the intubation time for the other 16 was 32 ± 33 h. The duration of postoperative intensive care unit stay was 6.5 ± 6.2 days, the length of hospital stay was 29 ± 15 days, and no in-hospital deaths occurred.
CONCLUSIONS
Simultaneous upper and lower body perfusion under moderate to deep hypothermia during thoracoabdominal aortic surgery may avoid not only spinal cord injury, but also cardiac and brain complications.

Journal of Atherosclerosis and... Feb 2023We aimed to examine the impact of overweight and obesity on mortality from nonrheumatic aortic valve disease.
AIM
We aimed to examine the impact of overweight and obesity on mortality from nonrheumatic aortic valve disease.
METHODS
In the Japan Collaborative Cohort Study, we analyzed data of 98,378 participants aged 40-79 years, with no history of coronary heart disease, stroke, or cancer at baseline (1988-1990) and who completed a lifestyle questionnaire including height and body weight; they were followed for mortality until the end of 2009. The Cox proportional hazards model was used to calculate the multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) of nonrheumatic aortic valve disease mortality according to body mass index (BMI) after adjusting for potential confounding factors.
RESULTS
During the median 19.2 years follow-up, 60 deaths from nonrheumatic aortic valve disease were reported. BMI was positively associated with the risk of mortality from nonrheumatic aortic valve disease; the multivariable HRs (95% CIs) were 0.90 (0.40-2.06) for persons with BMI <21 kg/m, 1.71 (0.81-3.58) for BMI 23-24.9 kg/m, 1.65 (0.69-3.94) for BMI 25-26.9 kg/m, and 2.83 (1.20-6.65) for BMI ≥ 27 kg/m (p for trend=0.006), compared with persons with BMI 21-22.9 kg/m. Similar associations were observed between men and women (p for interaction=0.56). Excluding those who died during the first ten years of follow-up or a competing risk analysis with other causes of death as competing risk events did not change the association materially.
CONCLUSIONS
Overweight and obesity may be independent risk factors for nonrheumatic aortic valve disease mortality in Asian populations.

Review
Lipomembranous fat necrosis (LFN) is an uncommon but distinct form of fat necrosis, which is characterized by eosinophilic, crenulated and/or serpiginous membranes. LFN exhibits macrocystic, microcystic and/or crushed features. LFN is routinely detectable on hematoxylin and eosin (H&E)-stained sections, and is present both in the acute phase and in the later or fibrous stage of necrotic fatty lesions. Smaller crushed LFN embedded within fibrous tissues may be difficult to recognize on H&E-stained sections, but can be highlighted by some staining techniques, including Masson trichrome, periodic acid-Schiff, orcein, long Ziehl-Neelsen stain, silver impregnation, phosphotungstic acid-hematoxylin and luxol fast blue staining. LFN was initially considered a specific feature of Nasu-Hakola disease, but has since been identified in various subcutaneous or intraabdominal lesions related to ischemic conditions or venous insufficiency. In addition, LFN is detectable in intra-articular loose bodies and aortic valves with or without dysfunction, suggesting that LFN is also associated with ischemia-like hypoxic conditions or malnutrition. LFN is considered to be a histological hallmark of hidden ischemic or hypoxic/malnourished conditions in various diseases; however, the exact mechanisms of LFN remain poorly understood. The present review described the clinicopathological features of this interesting, but poorly characterized, condition.

Aortic body tumors, specifically chemodectomas, are the second most common type of canine cardiac tumor; however, information about treatment is currently lacking. This study included dogs with a presumptive or definitive diagnosis of an aortic body chemodectoma that underwent treatment with toceranib phosphate. Cases were solicited via the American College of Veterinary Internal Medicine Cardiology, Internal Medicine, and Oncology listservs using an electronic survey. Cox multivariate analysis of factors potentially impacting survival time was completed. Twenty-seven (27) cases were included in analysis. The clinical benefit rate (complete remission, partial remission, or stable disease >10 weeks) was 89%. A median survival time of 478 days was found for those receiving toceranib alone ( = 14), which was not statistically different from those treated with additional modalities (521 days). No factors evaluated statistically impacted outcome. Further, prospective studies are warranted to evaluate the use of toceranib for the treatment of canine aortic body chemodectomas.
