OBJECTIVES: Axillary artery cannulation is commonly used in thoracic aortic surgery, often utilizing a sidearm graft. Although our institutional preference is femoral cannulation, we use axillary cannulation in select cases with a 'dirty' aorta on computed tomography scan or intraoperative transoesophageal echocardiography. Since 2011, we have routinely used an open Seldinger-guided approach for axillary cannulation. Here, we report our experience with open Seldinger-guided technique, evaluating its safety and efficacy...

Pulmonary embolism is a common clinical entity related to high mortality. About 200,000 to 300,000 patients die every year due to pulmonary embolism. The purpose of this article is to describe a case of a patient who on the second postoperative day after undergoing thromboembolectomy of the left femoral artery, manifested a massive pulmonary embolism. Due to cardiorespiratory collapse a combined treatment via extracorporeal life support (ECLS) and parallel catheter thrombolysis was decided and performed. By cardiorespiratory improvement and final stabilization the patient was successfully weaned from ECLS and the system was successfully removed...

OBJECTIVES: Patients on venoarterial or venovenous extracorporeal membrane oxygenation (ECMO) support may require venoarterial-venous (VAV-ECMO) configuration during follow-up. We report 12 cases of VAV-ECMO with significant outflow steal. METHODS: Between October 2014 and November 2016, a total of 97 patients (56.6 ± 12.0 years; 59 men/38 women; body surface area 1.84 ± 0.36 m 2 ) were supported with venoarterial ECMO ( n  = 85) or venovenous ECMO ( n  = 12)...

Composite tumors of cardiac myxoma and malignant lymphoma are extremely rare, with 11 of such cases reported in the literature. A 44-year-old man presented to us with abrupt right lower leg pain. A computed tomography angiogram revealed segmental obstruction of the right common femoral artery, and embolectomy was performed. The embolectomy specimen contained several clusters of degenerated round/oval atypical cells in the fibrinous or myxoid background. Immunohistochemical examination revealed that these atypical cells were negative for cytokeratin and non-specifically expressed CD45...

Osteochondroma is the most common benign bone tumor, which can sometimes cause vascular complications. Here we report two rare cases (a 48-year-old woman and a 28-year-old woman) presenting with pain and a pulsatile mass in the popliteal region. Computed tomography revealed pseudoaneurysm in the popliteal artery, which was closely associated with a protrusion of a femoral osteochondroma. Surgical repairs were performed, and the patients remained asymptomatic during follow-up. Therefore, considering the potential risk of vascular complications, close observation is mandatory in patients with femoral osteochondroma...

Fetal/perinatal hypoxia is one of the most common causes of perinatal morbidity and mortality and is frequently accompannied by vascular dysfunction. However, the mechanisms involved have not been fully delineated. We hypothesized that exposure to acute hypoxia-reoxygenation induces alterations in vascular O2 sensing/signaling as well as in endothelial function in the chicken embryo pulmonary artery (PA), mesenteric artery (MA), femoral artery (FA), and ductus arteriosus (DA). Noninternally pipped 19-day embryos were exposed to 10% O2 for 30 min followed by reoxygenation with 21% O2 or 80% O2 Another group was constantly maintained at 21% O2 or at 21% O2 for 30 min and then exposed to 80% O2 Following treatment, responses of isolated blood vessels to hypoxia as well as endothelium-dependent (acetylcholine) and -independent (sodium nitroprusside and forskolin) relaxation were investigated in a wire myograph...

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...

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...

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: Ninety-five per cent of those operated on for popliteal artery aneurysm (PA) are men. Thus, PAs in women are difficult to investigate. The aim was to study the disease in women. METHODS: Women treated for PA in 1987-2012, prospectively registered in the Swedish vascular registry, Swedvasc, supplemented by case records, were compared with the larger male cohort. Survival was determined through cross linkage with the National Population Registry. RESULTS: 1509 patients (men and women), 1872 legs, were identified; of these 74 patients (4...

The ultimate goal of the present work is to aid in the development of tools to assist in the treatment of cardiovascular disease. Gaining an understanding of hemodynamic parameters for medical implants allow clinicians to have some patient-specific proposals for intervention planning. In the present work an experimental and digital computational fluid dynamics (CFD) arterial model consisting of a number of major arteries (aorta, carotid bifurcation, cranial, femoral, jejunal, and subclavian arteries) were fabricated to study: (1) the effects of local hemodynamics (flow parameters) on global hemodynamics (2) the effects of transition from bedrest to upright position (postural change) on hemodynamics, and (3) diffusion of dye (medical drug diffusion simulation) in the arterial system via experimental and numerical techniques...

Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

The development of formalin-free fixatives is an urgent issue in gross anatomy because of the health hazard and the tissue-hardening actions of formalin. We recently identified the fixative, antimicrobial, and preservative effects of N-vinyl-2-pyrrolidone (NVP), a precursor of the water-soluble macromolecular polymer polyvinylpyrrolidone, in animal experiments. The aim of the present study is to investigate whether NVP solution can be used as an alternative to formalin in human cadaveric dissection. Twelve donated cadavers were infused with NVP via the femoral and common carotid arteries using a peristaltic pump...

Background: Polyarteritis nodosa (PAN) is a medium vessel vasculitis which causes significant morbidity and mortality. Usually, it presents with constitutional symptoms with angiographic evidence of aneurysms or segmental stenosis of arteries of mesenteric or renal vasculature. It is exceedingly uncommon for PAN to present with symptomatic progressive intermittent claudication. Case Presentation: We describe a 60-year-old male who presented with rapidly progressive intermittent claudication of his right leg...

KEY POINTS: Intrauterine growth restriction (IUGR) increases offspring risk of chronic diseases later in life, including cardiovascular dysfunction. Our prior studies suggest biventricular cardiac dysfunction and vascular impairment in baboons who were IUGR at birth because of moderate maternal nutrient reduction. The current study reveals changes in artery sizes, distensibility, and blood flow pattern in young adult IUGR baboons, which may contribute to cardiac stress. The pattern of abnormality observed suggests that vascular redistribution seen with IUGR in fetal life may continue into adulthood...
