Nutritional Status Assessed with Objective Data Assessment Correlates with a High-Risk Foot in Patients with Type 2 Diabetes.

Malnutrition and diabetes are likely to co-occur. There are few reports on the association between nutritional status and foot risk in patients with type 2 diabetes (T2D). Therefore, we aimed to investigate this relationship in this cross-sectional study. We investigated the relationships between objective data assessment (ODA), especially Controlling Nutritional Status (CONUT) score and foot risk, evaluated by the International Working Group on the Diabetic Foot (IWGDF), in consecutive patients with T2D. Patients were divided into groups 0 to 3 by IWGDF, and groups 1 to 3 were defined as high-risk groups. Among 469 patients, 42.6% (n = 200) of them had high-risk foot. Patients with high-risk foot were significantly older (71.2 ± 11.3 vs. 64.2 ± 13.4 years, p < 0.001) and had a longer duration of diabetes (18.0 ± 12.0 vs. 11.5 ± 10.0 years, p < 0.001) than those in the low-risk group. In the high-risk group, serum albumin level, total lymphocyte count, hemoglobin, and CONUT score were significantly worse, especially in older patients (≥75 years). Multivariate logistic regression analysis showed that there was a positive correlation between CONUT score and high-risk foot in older patients (OR, 1.37; 95% CI, 1.05−1.86; p = 0.021). Our results indicated that nutritional status, assessed by ODA, correlated with high-risk foot, especially in older patients with T2D.

Trigger finger is associated with risk of incident cardiovascular disease in individuals with type 2 diabetes: a retrospective cohort study.

INTRODUCTION: Trigger finger is one of the complications affecting the upper extremity in patients with diabetes. Diabetes is also a well-known risk factor that predisposes individuals to cardiovascular diseases (CVDs). This retrospective cohort study aimed to establish the association between trigger finger and the patients with incident CVD with type 2 diabetes. MATERIALS AND METHODS: Trigger finger was diagnosed by palpating a thickened tendon during flexion or on the manifestation of a locking phenomenon during extension or flexion of either finger. The relationship between trigger finger and other clinical parameters or complications of diabetes was examined by a comparative analysis. Cox regression analysis was used to evaluate the association between trigger finger and incidence of CVD. We calculated the propensity scores using sex, body mass index, age, smoking status, duration of diabetes, estimated glomerular filtration rate, hypertension, dyslipidemia, and hemoglobin A1c as the number of patients with incident CVD during the follow-up period was low. RESULTS: Among the 399 patients with type 2 diabetes, 54 patients had trigger finger. Patients with trigger finger were significantly older in age and had been suffering from diabetes for a longer duration. They also displayed worse renal function and glycemic control, along with a higher incidence of hypertension, neuropathy and nephropathy. During the average 5.66±1.12 years of follow-up, a total of 18 incidents occurred. According to the Cox regression analysis, trigger finger was shown to be associated with enhanced risk of the incidence of CVD after adjustment for the covariates (adjusted HR=3.33 (95% CI 1.25 to 8.66), p=0.017). CONCLUSIONS: Trigger finger is associated with the risk of incident CVD in patients with type 2 diabetes. Thus, clinicians must consider these factors at the time of diagnosis of such patients.

Limited joint mobility of the hand correlates incident hospitalisation with infection in patients with type 2 diabetes.

AIM: Limited joint mobility (LJM) of the hand is one of the important complications of diabetes. Diabetes is a risk factor for hospitalisation with infection. This study investigated the relationship between LJM of the hand and the incidence of hospitalisation with infection in type 2 diabetic patients. MATERIALS AND METHODS: LJM of hand was defined as the 'prayer sign' or 'table test'. The association between LJM of the hand and incident hospitalisations was evaluated using Cox regression analysis. The number of incident hospitalisations was small over the course of the study, which we compensated for by calculating propensity scores using age, body mass index, sex, duration of diabetes, creatinine, smoking status, haemoglobin A1c and dyslipidaemia. RESULTS: In this retrospective cohort study of 502 patients with type 2 diabetes, 102 patients had LJM of the hand. These patients were, on average, older and had worse renal function and glycaemic control, and a higher proportion of microangiopathy significantly. During the study period, 56 patients were hospitalised with infection. A Cox regression analysis showed that LJM of the hand was associated with an increased probability of incident hospitalisation with infection after adjustment for covariates (HR = 1.65 [95% CI 1.60-1.70], p < 0.001). CONCLUSIONS: Our results reveal that LJM of the hand is associated with incident of hospitalisation with infection. A diagnosis of LJM of the hand might, therefore, be a useful indicator for assessing the risk of hospitalisation with infection in type 2 diabetic patients.

Malnutrition assessed by controlling nutritional status is correlated to carotid atherosclerosis in patients with type 2 diabetes.

Diabetes and malnutrition sometimes overlap. Little is known about the relationship between malnutrition and subclinical atherosclerosis in patients with type 2 diabetes. This cross-sectional study investigated this relationship in patients with type 2 diabetes. We evaluated the relationships between malnutrition assessed by controlling nutritional status (CONUT) score and subclinical atherosclerosis assessed by carotid intima-media thickness (IMT) and carotid plaque scores in 461 consecutive patients with type 2 diabetes. Nutritional assessment indicated that 38% of patients were malnourished (CONUT ≥3). Carotid IMT and carotid plaque scores were significantly higher in patients with malnutrition. Multivariate linear regression analyses revealed that a high CONUT score (CONUT ≥3) was correlated with mean IMT (ß = 0.196, p = 0.043) and max IMT (ß = 0.243, p = 0.011) in patients taking statins and was also correlated with mean IMT (ß = 0.287, p = 0.004), max IMT (ß = 0.308, p = 0.002), and plaque score (ß = 0.190, p = 0.044) in patients not taking statins after adjusting for age, sex, duration of diabetes, body mass index, hemoglobin A1c, creatine, smoking, and hypertension. Our results demonstrate a relationship between malnutrition and subclinical atherosclerosis in patients with type 2 diabetes.

Platelet to lymphocyte ratio correlates with diabetic foot risk and foot ulcer in patients with type 2 diabetes.

Diabetic foot ulcer is a major complication in patients with diabetes. Platelet-lymphocyte ratio (PLR) has been reported to have a predictive effect to some diabetic complications in recent years. However, it has not been fully elucidated about the relationship between diabetic foot risk or diabetic foot ulcer and PLR in patients with type 2 diabetes. Therefore, we aimed to evaluate this relationship. In this cross-sectional study, we evaluated the relationships between patient's diabetic foot risk with the criteria of the International Working Group on the Diabetic Foot (IWGDF) and prevalent foot ulcer, and PLR in 453 consecutive patients with type 2 diabetes. Propensity score analysis was used to adjust the difference of covariates; age, sex, duration of diabetes, body mass index (BMI), HbA1c, current smoking, hypertension, dyslipidemia, neuropathy, PAD, foot deformity and history of foot ulcers. PLR was higher in patients with high risk diabetic foot or foot ulcer (117 ± 40 vs. 107 ± 31, p = 0.003 and 148 ± 65 vs. 113 ± 56, p < 0.001). A receiver-operating characteristic curve demonstrated that PLR of 130.6 constitutes the cut-off value for prevalent foot ulcer with sensitivity 0.85 and specificity 0.70. Multivariate logistic regression analysis revealed that PLR was positively correlated with prevalent foot ulcer (odds ratio, 1.02; 95% confidence interval 1.01-1.04, p = 0.003) after adjusted for several variables with propensity score analysis. Our results demonstrated that PLR can be a marker for high risk diabetic foot and diabetic foot ulcer in patients with type 2 diabetes.

Neutrophil-lymphocyte ratio correlates with limited joint mobility of hand in patients with type 2 diabetes.

Limited joint mobility (LJM) of hand, which is one of the complications of diabetic hand, is associated with diabetic micro- and macroangiopathy although the precise pathogenesis is not completely understood. Neutrophil-lymphocyte ratio (NLR), a simple and novel inflammatory marker, has been reported to have a predictive effect to some diabetic complications in recent years. However, it is not elucidated about the relationship between LJM of hand and NLR in patients with type 2 diabetes. We evaluated the relationships between LJM of hand and NLR in 335 consecutive patients with type 2 diabetes in this cross-sectional study. LJM of hand was diagnosed by a 'prayer sign' or 'table test'. LJM of hand was present in 80 patients. The patients with LJM of hand had significantly older age, longer duration of diabetes, worse renal function, and higher proportion of diabetic neuropathy, retinopathy and nephropathy. NLR in patients with LJM of hand was higher than that in patients without LJM of hand (2.54 ± 1.46 vs. 2.11 ± 1.04, p = 0.004). Multivariate logistic regression analysis revealed that LJM of hand was positively correlated with NLR (odds ratio, 1.31; 95% confidence interval 1.03-1.69, p = 0.027) after adjustment for age, sex, duration of diabetes, body mass index, hemoglobin A1c, hypertension and dyslipidemia. Our results demonstrate a positive relation between LJM of hand and NLR in patients with type 2 diabetes.

Relationship between limited joint mobility of hand and carotid atherosclerosis in patients with type 2 diabetes.

AIM: Limited joint mobility (LJM) of hand, which is one of a complication of diabetic hand, has a close association with diabetic microangiopathy. However, it remains to be elucidated about the relationships between LJM of hand and subclinical atherosclerosis in patients with type 2 diabetes. Therefore, we conducted a cross-sectional study to evaluate the relationships between LJM of hand and carotid intima-media thickness (IMT) and plaque score in patients with type 2 diabetes. METHODS: We evaluated the relationships between LJM of hand, and carotid IMT and plaque score, evaluated by carotid ultrasound examination, in 341 consecutive patients with type 2 diabetes. LJM of hand was diagnosed using a 'prayer sign' or 'table test'. RESULTS: LJM of hand was present in 72 patients. Carotid IMT and plaque score were higher in patients with LJM of hand than those in patients without (1.45±0.66vs. 1.14±0.68mm, P=0.013 and 8.0±5.3vs. 5.4±4.8mm, P<0.001). Multivariate linear regression analysis revealed that LJM of hand was positively correlated with plaque score (ß=0.423, P=0.043) after adjusted for age, sex, durations of diabetes, body mass index, hemoglobin A1c, creatinine, uric acid, smoking, hypertension and dyslipidemia. CONCLUSIONS: Our results demonstrate a relation between LJM of hand and subclinical atherosclerosis, especially plaque score, in patients with type 2 diabetes. Diagnosis of diabetic hand is simple and non-invasive, and thus is a useful method for assessment of subclinical atherosclerosis in patients with type 2 diabetes.

Relationship between limited joint mobility of the hand and diabetic foot risk in patients with type 2 diabetes.

BACKGROUND: Foot ulceration is a serious problem for patients with type 2 diabetes (T2D), and the early detection of risks for this condition is important to prevent complications. The present cross-sectional study in T2D patients determined the relationship between limited joint mobility (LJM) of the hand and diabetic foot risk classified using the criteria of the International Working Group on the Diabetic Foot (IWGDF). METHODS: Relationships between LJM of the hand and foot risk according to IWGDF category, HbA1c, age, body mass index, blood pressure, estimated glomerular filtration (eGFR), and diabetic complications (including diabetic peripheral neuropathy [DPN] and peripheral arterial disease [PAD]) were evaluated in 528 consecutive T2D patients. Poor glycemic control was defined as HbA1c ≥ 7%. RESULTS: Patients with LJM of the hand were older and had a longer duration of diabetes, a higher prevalence of diabetic complications, including DPN and PAD, and a higher IWDGF category (all P < 0.001). Multivariate logistic regression analysis revealed that the foot risk assessed with IWDGF category was correlated with age (odds ratio [OR] 1.04; 95% confidence interval [CI] 1.01-1.06; P = 0.001), poor glycemic control (OR 1.66; 95% CI 1.00-2.77; P = 0.04), eGFR (OR 0.98; 95% CI 0.97-0.99; P = 0.02), and the presence of LJM of the hand (OR 3.86; 95% CI 2.21-6.86; P < 0.001). CONCLUSIONS: The results demonstrate a correlation between LJM of the hand and foot risk. Diagnosis of diabetic hand is simple and non-invasive, and is thus a useful method for assessing the risk of diabetic foot in T2D patients.

Visit-to-visit variability in systolic blood pressure is a novel risk factor for the progression of coronary artery calcification.

Recent studies have suggested that variability in the systolic blood pressure (SBP) is a risk factor for cardiovascular disease (CVD). The aim of this study was to investigate the relationship between variability in the SBP and the progression of coronary artery calcification (CAC), which is a useful marker for CVD. We measured SBP in 164 consecutive patients at every visit over the course of a year and calculated the coefficient of variation and s.d. of the SBP. We performed a follow-up study using multislice computed tomography to assess the progression of the CAC score, the mean interval of which was 3.93 ± 1.36 years. We then evaluated the relationship between variability in the SBP and progression of the CAC score. The coefficient of variation for the SBP correlated positively with the progression of the CAC score (r=0.4382, P<0.0001). Multiple regression analysis demonstrated that the coefficient of variation of the SBP (ß=0.3826, P<0.0001) was independently associated with the progression of the CAC score. The visit-to-visit variability in SBP could be a novel risk factor for the progression of CAC.

Morning pulse pressure is associated more strongly with elevated albuminuria than systolic blood pressure in patients with type 2 diabetes mellitus: post hoc analysis of a cross-sectional multicenter study.

AIMS: Recently, focus has been directed toward pulse pressure as a potentially independent risk factor for micro- and macrovascular disease. This study was designed to examine the relationship between pulse pressure taken at home and elevated albuminuria in patients with type 2 diabetes. METHODS: This study is a post hoc analysis of a cross-sectional multicenter study. Home blood pressure measurements were performed for 14 consecutive days in 858 patients with type 2 diabetes. We investigated the relationship between systolic blood pressure or pulse pressure in the morning or in the evening and urinary albumin excretion using univariate and multivariate analyses. Furthermore, we measured area under the receiver-operating characteristic curve (AUC) to compare the ability to identify elevated albuminuria, defined as urinary albumin excretion equal to or more than 30 mg/g creatinine, of systolic blood pressure or pulse pressure. RESULTS: Morning systolic blood pressure (ß=0.339, P<0.001) and morning pulse pressure (ß=0.378, P<0.001) were significantly associated with logarithm of urinary albumin excretion independent of other potential co-factors. AUC for elevated albuminuria in morning systolic blood pressure and morning pulse pressure were 0.668 (0.632-0.705; P<0.001) and 0.694 (0.659-0.730; P<0.001), respectively. AUC of morning pulse pressure was significantly greater than that of morning systolic blood pressure (P=0.040). CONCLUSIONS: Our findings implicate that morning pulse pressure is associated with elevated albuminuria in patients with type 2 diabetes, which suggests that lowering morning pulse pressure could prevent the development and progression of diabetic nephropathy.

Visit-to-visit blood pressure variability is a novel risk factor for the development and progression of diabetic nephropathy in patients with type 2 diabetes.

OBJECTIVE: Recent study has suggested that not only the presence of hypertension but also the variability in systolic blood pressure (SBP) are risk factors for vascular disease and organ damage. The aim of this study was to investigate the relationship between visit-to-visit variability in SBP and change in urinary albumin excretion (UAE) or development of albuminuria in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS: We measured SBP in 354 consecutive patients at every visit during 1 year and calculated the coefficient of variation (CV) of SBP. We performed a follow-up study to assess change in UAE or development of albuminuria, the mean interval of which was 3.76 ± 0.71 years. Then, we evaluated relationships of variability of SBP to diabetic nephropathy using multiple regression analysis and multiple Cox regression model. RESULTS: Multiple regression analysis demonstrated that CV of SBP was independently associated with change in UAE (ß = 0.1758; P = 0.0108). Adjusted Cox regression analyses demonstrated that CV of SBP was associated with an increased hazard of development of albuminuria; hazard ratio was 1.143 (95% CI 1.008-1.302). CONCLUSIONS: Visit-to-visit variability in SBP could be a novel risk factor for the development and progression of diabetic nephropathy in patients with type 2 diabetes.

Testosterone deficiency induces markedly decreased serum triglycerides, increased small dense LDL, and hepatic steatosis mediated by dysregulation of lipid assembly and secretion in mice fed a high-fat diet.

OBJECTIVE: Although low serum testosterone (T) is associated with metabolic disorders, the mechanism of this association is unclear. The objective of the present study was to investigate the combined effects of T deficiency and a high-fat diet (HFD) on hepatic lipid homeostasis in mice. MATERIALS/METHODS: Orchiectomized (ORX) mice and sham-operated (SHAM) mice were randomly divided into five groups: SHAM mice fed a standard diet (SD), SHAM mice fed HFD, ORX mice fed SD, ORX mice fed HFD, and ORX mice fed HFD with T supplementation. After 4weeks of treatment, we investigated the synthesis and secretion of lipids in the liver and detailed serum lipoprotein profiles in each group. RESULTS: ORX mice fed HFD showed increased hepatic steatosis, markedly decreased serum triglyceride (TG) and TG-VLDL content, and increased serum very small-LDL content. Gene expression analysis revealed that ORX mice fed HFD showed significantly decreased expression of microsomal triglyceride transfer protein, lipin-1, peroxisome proliferator-activated receptor (PPAR)-α and PPAR-γ coactivator 1-α, and significantly increased sterol regulatory element-binding protein-1, diacylglycerol acyltransferase-2 and fatty acid synthase. Reduction of hepatic AMPK phosphorylation was observed in ORX mice fed HFD. These perturbations in ORX mice fed HFD were normalized to the levels of SHAM mice fed HFD by T supplementation. CONCLUSION: T deficiency is associated with failure of lipid homeostasis mediated by altered expression of genes involved in hepatic assembly and secretion of lipids.

A difference in systolic blood pressure between arms and between lower limbs is a novel risk marker for diabetic nephropathy in patients with type 2 diabetes.

Recent studies have demonstrated that a difference in systolic blood pressure (SBP) between arms is associated with both vascular disease and mortality. The aim of this study was to investigate the relationship between a difference in SBP between arms and between lower limbs and the degree of albuminuria, which is an established marker for cardiovascular disease and diabetic nephropathy in patients with Type 2 diabetes. We measured blood pressure in the arms and lower limbs of 314 consecutive patients with Type 2 diabetes, and we calculated a difference in SBP between arms and between lower limbs. We then evaluated the relationship of the difference in SBP between arms and between lower limbs to the degree of urinary albumin excretion (UAE). The average difference in SBP between arms and between lower limbs was 3.52±3.94 and 9.66±14.1 mm Hg, respectively. Multiple regression analyses demonstrated that a difference in SBP between arms (ß=0.172, P=0.0239) and between lower limbs (ß=0.238, P=0.0033) independently correlated with the logarithm of the UAE. Multiple logistic regression analyses showed that a difference in SBP of 10 mm Hg between arms (odds ratio 12.23 (95% CI 1.130-132.35), P<0.0393) and a difference in SBP of 15 mm Hg between lower limbs (odds ratio 4.291 (95% CI 1.403-13.123), P<0.0106) correlated with the risk of albuminuria. A difference in SBP between arms and between lower limbs, therefore, could be a novel risk marker for diabetic nephropathy in patients with Type 2 diabetes.

Serum pepsinogen I/II ratio is correlated with albuminuria in patients with type 2 diabetes.

Helicobacter pylori infection, which is a common cause of atrophic gastritis, has been reported to represent a causal factor increasing the vascular damage and consequent albuminuria. On the other hand, decreased serum pepsinogen (PG) I/II ratio can be used to assess gastric mucosal atrophy. To the best of our knowledge, there are no studies investigating the correlation between PG I/II ratio and diabetic nephropathy. Therefore, we investigated a relationship between PG I/II ratio and degree of urinary albumin excretion (UAE) in patients with type 2 diabetes. We evaluated relationships between PG I/II ratio and degree of UAE or estimated glomerular filtration rate as well as various factors, including age, body mass index, blood pressure, hemoglobin A1c, serum lipid concentrations, uric acid or C-reactive protein in 333 consecutive patients with type 2 diabetes. PG I/II ratio correlated positively with logarithm of UAE in all patients (r = 0.174, P = 0.0016) and in patients without Helicobacter pylori infection (r = 0.352, P < 0.0001). Multiple regression analysis identified that PG I/II ratio correlated independently with logarithm of UAE in all patients (ß = 0.264, P = 0.0005) and in patients without Helicobacter pylori infection (ß = 0.295, P = 0.0022). These data suggest that serum PG I/II ratio is correlated with diabetic nephropathy.

Visit-to-visit variability in systolic blood pressure is correlated with diabetic nephropathy and atherosclerosis in patients with type 2 diabetes.

OBJECTIVE: Recent studies make remarks on the effect of variability in systolic blood pressure (SBP) on the development of cardiovascular disease. The aim of this study was to investigate the relationship between the variability in SBP and the degree of diabetic nephropathy and atherosclerosis in patients with type 2 diabetes. METHODS: We measured SBP in 422 consecutive patients with type 2 diabetes at every visit during a year, and we calculated the coefficient of variation (CV) of SBP. Then, we evaluated relationships of variability of SBP to degree of urinary albumin excretion (UAE), which is a useful marker for cardiovascular disease as well as diabetic nephropathy, ankle-brachial index (ABI) and pulse wave velocity (PWV). RESULTS: CV of SBP positively correlated with logUAE (r=0.210, P<0.0001) or PWV (r=0.409, P<0.0001), whereas CV of SBP inversely correlated with ABI (r=-0.098, P=0.0463). Multiple regression analysis demonstrated that CV of SBP independently correlated with logUAE (ß=0.149, P=0.0072), PWV (ß=0.337, P<0.0001) or ABI (ß=-0.162, P=0.0101). CONCLUSIONS: Not only average SBP but also variability in SBP is correlated with diabetic nephropathy and atherosclerosis in patients with type 2 diabetes.

Relationship between cardio-ankle vascular index (CAVI) and coronary artery calcification (CAC) in patients with type 2 diabetes mellitus.

Early detection of atherosclerosis is important for patients with type 2 diabetes mellitus because cardiovascular disease (CVD) is a main cause of death in these people. In this study, we investigated the relationship between an arterial stiffness parameter called cardio-ankle vascular index (CAVI) and coronary artery calcification (CAC). We performed a cross-sectional study in 371 type 2 diabetic patients with clinical suspicion of coronary heart disease (CHD). We evaluated the relationships between CAVI and CAC score determined by multislice computed tomography as well as major cardiovascular risk factors, including age, body mass index, hemoglobinA1c and the Framingham CHD risk score. CAVI was correlated with age (r = 0.301, p < 0.0001), uric acid (r = 0.236, p < 0.0001), estimated glomerular filtration rate (r = -0.145, p = 0.0166), CHD risk score (r = 0.327, p < 0.0001) and log (CAC + 1) (r = 0.303, p < 0.0001). The area under the receiver operating characteristic curve for CAVI was higher than that of CHD risk score in predicting CAC >0, CAC >100, CAC >400, or CAC >1000. CAVI is positively correlated with CAC, and is considered to be a useful method to detect CAC.

Five-item version of the international index of erectile function correlated with albuminuria and subclinical atherosclerosis in men with type 2 diabetes.

AIM: There is increasing evidence of a strong link between erectile dysfunction and atherosclerosis. The aim of this study was to evaluate the relationships between the 5-item version of the International Index of Erectile Function (IIEF-5) score and albuminuria as well as markers of subclinical atherosclerosis in men with type 2 diabetes. METHODS: We evaluated the relationship of the IIEF-5 score with the degree of urinary albumin excretion, pulse wave velocity, ankle-brachial index or toe-brachial index (n = 125) as well as with major cardiovascular risk factors, including age, blood pressure, serum lipid concentration and hemoglobin A1c, body mass index, severity of diabetic retinopathy or nephropathy, and presence of neuropathy or cardiovascular disease in 197 men with type 2 diabetes. RESULTS: The mean IIEF-5 score was 10.0 ± 6.9. The IIEF-5 score was inversely correlated with age or duration of diabetes, and positively correlated with diastolic blood pressure or serum total cholesterol concentration. The IIEF-5 score inversely correlated with log (urinary albumin excretion; r =-0.190, p =0.0078) or pulse wave velocity (r =-0.255, p =0.0003), and positively correlated with the toe-brachial index (r = 0.379, p < 0.0001). The IIEF-5 score was lower in patients with proliferative diabetic retinopathy than in patients with no diabetic retinopathy, and in patients with macroalbuminuria than in patients with normoalbuminuria. The IIEF-5 score was also lower in patients with neuropathy or cardiovascular disease than without. CONCLUSIONS: The IIEF-5 score correlated with diabetic micro- and macroangiopathy in men with type 2 diabetes.

[A case of idiopathic omental bleeding treated successfully with transarterial embolization].

A 58-year-old man was brought to our hospital with left upper abdominal pain which suddenly appeared on the previous evening. An abdominal CT scan showed localized retention of ascites, a slightly high density mass under the left upper abdominal wall, with a high density area detected within the mass, which was suggestive of leakage of contrast medium from peripheral branches of the omental artery. From these findings intraperitoneal hemorrhage caused by bleeding from the greater omentum was suspected. Angiographic examination of the abdomen indicated extravasation of contrast medium from blood vessels of the right gastroepiploic artery. Transarterial embolization was carried out and permanent hemostasis was achieved. Injury, anticoagulant, neoplasms, varix, torsion of the omentum, and segmental arterial mediolysis (SAM) etc have been reported as causes of omental bleeding, but none of these were found in our case. We diagnosed the present case as idiopathic omental bleeding.
