The present study explored the correlation of coronary heart disease(CHD) with blood stasis syndrome in postmenopausal women with artery elasticity and endothelial function indexes and evaluated the diagnostic efficacy of the prediction model via logistic regression and receiver operating characteristic(ROC) curve model. A retrospective comparison was made between 366 postmenopausal CHD patients from August 1, 2020, to September 30, 2021, in the Department of Cardiology of Integrated Traditional Chinese and Western Medicine of China-Japan Friendship Hospital, who were divided into the blood stasis syndrome group(n=196) and the non-blood stasis syndrome group(n=170). General clinical characteristics of the two groups were compared. Multivariate logistic regression analysis was used to probe the correlation of CHD with blood stasis syndrome in postmenopausal women with brachial-ankle pulse wave velocity(baPWV), ankle-brachial index(ABI), and flow-mediated dilatation(FMD), and the ROC curve was drawn to evaluate the diagnostic efficiency of the prediction model. Multivariate logistic regression analysis showed that the correlation coefficients of CHD with blood stasis syndrome in postmenopausal women with baPWV, ABI, and FMD were 1.123, 0.109, and 0.719, respectively(P=0.004, P=0.005, P<0.001),and the regression equation for predicting probability P was P=1/[1+e~(-(3.131+0.116×baPWV-2.217×ABI-0.330×FMD))]. ROC curve analysis suggested that in the context of baPWV≥19.19 m·s~(-1) or ABI≤1.22 or FMD≤9.7%, it was of great significance to predict the diagnosis of CHD with blood stasis syndrome in postmenopausal women. The AUC of baPWV, ABI, FMD, and prediction probability P was 0.763, 0.607, 0.705, and 0.836, respectively. The AUC of prediction probability P was higher than that of each index alone(P<0.001), and the sensitivity and specificity were 0.888 and 0.647, respectively. The results demonstrate that baPWV, ABI, and FMD are independently correlated with CHD with blood stasis syndrome in postmenopausal women, and show certain independent predictive abilities(P<0.05). The combined evaluation of the three possesses the best diagnostic efficiency.

BACKGROUND/AIMS: The strategy of access care at out center involves the use of ultrasound (USG) in case of physical examination (PE) abnormality. USG determines the need of angiography. This study investigated the possible association between the need for percutaneous transluminal angioplasty (PTA) and hemodynamic parameters of USG. The study also assessed the effects of this monitoring strategy on outcomes in comparison with a historical control. METHODS: A retrospective study of the medical records of 127 patients (65 PTA, 62 non-PTA) was conducted. Data were analyzed using logistic regression analysis and receiver operating characteristic curve. Fistula outcomes and intervention rates were calculated and compared with 100 historic controls. RESULTS: Logistic regression analysis showed that brachial artery flow volume (FV) < 612.9 mL/min or brachial artery resistance index (RI) > 0.63 was independently associated with the need for PTA. This monitoring strategy showed an a reduction in thromboses (0.02 ± 0.11 events/arteriovenous fistula [AVF]-year vs. 0.07 ± 0.23 events/AVF-year, p = 0.046), reduction in central venous catheter placement (0.01 ± 0.05 events/AVF-year vs. 0.06 ± 0.22 events/AVF-year, p = 0.010), reduction in access loss (0.02 ± 0.13 events/AVF-year vs. 0.19 ± 0.34 events/AVF-year, p = 0.015), and increase in access selective repair (0.49 ± 0.66 events/AVF-year vs. 0.21 ± 0.69 events/AVF-year, p = 0.003), compared to historic control. CONCLUSIONS: There was significant stenosis if brachial artery FV was < 612.9 mL/min or RI was > 0.63 for PE abnormality. These parameters should be used as markers for assessing PTA risk in hemodialysis patients. Addition of USG to determine the need of angiography after detection of PE abnormality leads to decreases in access thrombosis, catheter placement, and access loss despite increasing access intervention rates compared to clinical monitoring.

The authors report a rare variation of the vasculature in the upper limbs of an 84-year-old male cadaver. A high bifurcation of the brachial artery occurred bilaterally at the proximal one-third of each arm. The radial arteries were larger than the ulnar arteries and gave origin to the common interosseous arteries. At the cubital fossa, the ulnar arteries traversed medial to the median nerves, continuing superficial to all forearm muscles except the palmaris longus tendon, characteristic of superficial brachioulnar arteries. The aforementioned variations have rarely been reported in previous literature and demonstrate important clinical significance in relation to accidental intra-arterial injections, errors in blood pressure readings, as well as orthopedic, plastic, and vascular surgeries of the upper limbs.

Antiphospholipid antibodies may be produced in cases involving autoimmune diseases and can sometimes be caused by infections, such as Mycoplasma pneumoniae infection. However, antiphospholipid antibodies causing thrombosis associated with M. pneumoniae pneumonia in children have rarely been reported. We report a case of an 8-year-old boy with M. pneumoniae pneumonia with antiphospholipid antibodies, complicated by brachial artery thrombosis. He was found to have antiphospholipid antibodies and low protein S levels. The brachial artery thrombus was removed via thrombectomy. The titers of antiphospholipid antibodies turned normal within 5 months. This is a rare case of M. pneumoniae infection with brachial artery thrombosis associated with transient antiphospholipid antibodies.

Entrapment neuropathies of the peripheral nervous system are frequently encountered due to anatomical variations. Median nerve is the most vulnerable nerve to undergo entrapment neuropathies. The clinical complications are mostly manifested by median nerve impingement in forearm and wrist areas. Median nerve entrapment could also occur at the arm, due to the presence of ligament of Struthers. Here we report a rare case of proximal entrapment of median nerve and brachial artery in the arm by an abnormally formed musculo-fascial tunnel. The tunnel was formed by the muscle fibers of brachialis and medial intermuscular septum in the lower part of arm. Due to this, the median nerve coursed deep, below the tunnel and continued distally into the forearm, underneath the pronator teres muscle and hence did not appear as a content of cubital fossa. The present entrapment of neurovascular structures in the tunnel might lead to pronator syndromes or other neurovascular compression syndromes.

8.Aortoiliac Occlusive Disease as a Cause of Allograft Kidney Dysfunction and Refractory Hypertension
Kosin Medical Journal 2019;34(2):168-172
Aortoiliac occlusive disease (AIOD), especially proximal to the transplant artery, in kidney transplant patient activates the renin-angiotensin-aldosterone system by limiting graft renal perfusion and causes symptoms that can occur with transplant renal artery stenosis (TRAS) such as refractory hypertension, water retention, and graft renal dysfunction. Immediate clinical suspicion is difficult due to the nature of the progressive disease unlike TRAS. Herein, we present an interesting case of bilateral common iliac artery occlusion (AIOD, TASC II, type C) that manifested as uncontrolled blood pressure and decreased allograft function in a patient who had kidney transplant 17 years ago. The patient was successfully diagnosed with duplex scan, ankle-brachial index (ABI) and computed tomography angiography and treated with percutaneous luminal angioplasty and stent graft insertion.

PURPOSE: Isometric handgrip exercise (IHE) is an easy and accessible form of exercise that has beneficial effects on blood pressure (BP). However, it remains unclear whether IHE is similar benefits on arterial stiffness and endothelial function compared with aerobic exercise (AE) in elderly hypertensive patients. The aim of this study was to compare the effects of IHE versus AE on arterial stiffness and endothelial function in elderly hypertensive patients.METHODS: We conducted a randomized controlled trial with a three-arm design. Fifty-four elderly hypertensive patients (15 men; mean age, 69±6 years; systolic blood pressure, 131.2±14.7; diastolic blood pressure, 80.2±7.9 mm Hg) were randomized to IHE training (n=18), AE training (n=21), or non-exercise control group (n=21) for 12 weeks. Bilateral IHE training was performed four times of 2 minutes at 30% of maximal voluntary contraction with three times per week. AE training was performed brisk walking for 30 minutes at moderate intensity with three times per week. Carotid-femoral pulse wave velocity (PWV), augmentation index heart rate corrected (AIx@75 bpm) and brachial artery flow-mediated vasodilation (FMD) as indices of arterial stiffness and endothelial function were measured at baseline and after the intervention.RESULTS: Following 12-week intervention, resting BP was significantly decreased in both IHE (p=0.001) and AE groups (p=0.002). AIx@75 bpm and FMD were unchanged in the all groups. However, PWV was significantly decreased in both IHE and AE groups (IHE, 10.9±2.3 to 9.9±2.1 m/s [p<0.001]; AE, 10.5±2.0 to 9.4±1.6 m/s [p=0.001]), without any change in the control group.CONCLUSION: These findings suggest that both IHE and AE trainings were comparable effect in improving arterial stiffness in elderly hypertensive patients.

PURPOSE: Although common femoral artery endarterectomy (CFAE) is regarded as the standard treatment modality for common femoral artery (CFA) disease, availability of advanced endovascular techniques has resulted in an increased number of CFA disease being treated. We evaluated clinical outcomes in a contemporary series of patients who were treated for CFA disease using endarterectomy alone or combined with endovascular treatment. MATERIALS AND METHODS: We retrospectively reviewed 46 patients from November 2001 through December 2007. The treated lesions were divided into 4 groups based on operative procedure: group I (n=11), CFAE alone; group II (n=15), CFAE and iliac artery (IA) endovascular treatment; group III (n=6), CFAE and superficial femoral artery (SFA) endovascular treatment; group IV (n=14), CFAE and IA and SFA endovascular treatment or bypass surgery. RESULTS: The degree of CFA steno-occlusion was not different among the groups. The 3-year primary patency rates of each group were 88.9±10.5%, 60.0±14.5%, 62.5±21.3%, and 83.9±10.4%, respectively. The 3-year primary assisted patency rates were 100%, 70.0±13.0%, 62.5±21.3%, and 89.3±10.4%, while 3-year secondary patency rates were 100%, 80.0±13.0%, 62.5±21.3%, and 92.3±7.4%, respectively. There was no procedure-related mortality. Significant improvement of ankle-brachial index was achieved in all groups. CONCLUSION: CFAE alone is the treatment of choice for excellent patency and clinical improvement in steno-occlusive lesions confined to the CFA. In multiple steno-occlusive diseases, this procedure could be combined with endovascular procedures to reduce the operative risk in conditions with high morbidity.
