The transfemoral arterial approach is used to gain access for angiography, percutaneous coronary interventions, or various endovascular therapies. To decrease the risk of procedure-related vascular complications, it is recommended to puncture the common femoral artery in its middle segment. However, due to inadequate access or anatomical variability, various complications, including hematoma, pseudoaneurysm, arteriovenous fistula, thrombosis, or dissection, can occur after transfemoral arterial interventions...

Qing Zhai, Yun Wang, Ayong Tian
RATIONALE: The increasingly intraoperative use of indocyanine green (ICG) means that it is necessary to be aware of both its advantages and potential adverse effects. PATIENT CONCERNS: A 76-year-old woman developed symptoms of sudden severe hemodynamic instability while undergoing coronary artery bypass grafting with ICG injection to detect the patency of the graft. The main clinical manifestations were a sudden drop in blood pressure and increased heart rate. DIAGNOSES: Severe side effects or allergic reaction of ICG...

RATIONALE: Osteosarcoma is the most common malignant bone tumor in children and adolescents. Metastasis occurs early, the mortality rate is high, and the tumor results in a tremendous physical, mental, and economic burden on patients. Therefore, the treatment of osteosarcoma has been important for orthopedic surgeons. However, treatment has always been a difficult problem globally. PATIENT CONCERN: We present the case of a 22-year-old girl with increasing local pain in the distal left thigh...

In patients with abdominal aortic aneurysms (AAA) and complete iliac occlusion, endovascular aortic aneurysm repair (EVAR) using a bifurcated stent graft has clear advantages over aortouniiliac stent grafts. Bifurcated stent grafts had improved hemodynamic flow and increased primary and secondary patency rates compared with aortouniiliac stent grafts. The use of aortouniiliac stent grafts with femorofemoral crossover bypass is associated with complications including infection of the prosthesis, steal phenomenon, and the associated difficulties for further endovascular access at the site of the femoral anastomosis...

AIMS: To evaluate the relationship between overactive bladder (OAB) and systemic atherosclerosis in a cohort of women. METHODS: In this case-control study, we assessed atherosclerosis indicators, such as Framingham risk scores and carotid and femoral artery intima-media thickness, and evaluated possible bladder wall responses to atherosclerosis using endovaginal color Doppler ultrasound and the detection of urinary cytokines in women with OAB and in controls. Quantitative assessment of blood perfusion at the bladder neck was performed using a method that allows for the dynamic monitoring of flow in a predefined region of interest at every point of the cardiac cycle...

BACKGROUND/AIMS: Limb ischemia occurs in peripheral artery disease (PAD). Sympathetic nerve activity (SNA) that regulates blood flow directed to the ischemic limb is exaggerated during exercise in this disease, and transient receptor potential channel A1 (TRPA1) in thin-fiber muscle afferents contributes to the amplified sympathetic response. The purpose of the present study was to determine the role of proteinase-activated receptor-2 (PAR2) in regulating abnormal TRPA1 function and the TRPA1-mediated sympathetic component of the exercise pressor reflex...

OBJECTIVES: To assess the feasibility of axillary transcatheter aortic valve implantation (TAVI) using the Lotus valve. BACKGROUND: TAVI is used to treat patients with severe aortic stenosis, with transfemoral (TF) access being the safest and most widely used route. In patients unsuitable for this, there are reports that the axillary artery may be safest alternative access route. The Lotus device is a fully retrievable 2nd generation transcatheter heart valve which is licensed for femoral and transaortic access...

Hydrogen sulfide, a toxic gas, at low concentrations is also a biological mediator in animals. In the colon, hydrogen sulfide is produced by intestinal tissues and gut sulfur bacteria. Gut-derived molecules undergo liver metabolism. Portal hypertension is one of the most common complications contributing to the high mortality in liver cirrhosis. We hypothesized that the colon-derived hydrogen sulfide may affect portal blood pressure. Sprague-Dawley rats were maintained either on tap water (controls) or on water solution of thioacetamide to produce liver cirrhosis (CRH-R)...

Objectives: Regular exercise is known to reduce arterial stiffness (AS) in hemodialysis patients. However, the impact of a more realistic intradialytic form of exercise, such as pedaling, is unclear. We aimed to examine 1) the effect of intradialytic pedaling exercise on AS over 4 months, and 2) the longer-term effect of pedaling on AS 4 months after exercise cessation. Methods: Patients on stable in-center hemodialysis (3x/week) were randomly assigned 1:1 to either intradialytic pedaling exercise (EX) or to a control group receiving usual hemodialysis (nonEX) for 4 months...
