BACKGROUND: Cardiac magnetic resonance (CMR) has promise of being able to provide frequent cardiac morphology and function evaluations noninvasively for repeated follow-ups of pulmonary arterial hypertension (PAH) patients after the initial right heart catheterization (RHC) diagnosis. By using the noninvasive CMR indices, the present study aimed to formulate and validate a prediction model of mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR). METHODS: Both Derivation Cohort (N=25) and Validation Cohort (N=25) of PAH patients underwent CMR and RHC within one week...

BACKGROUND: Prevalent hemodialysis patients with vascular access consisting of a central venous catheter (CVC) are continuously increasing over the years. Improvement in evolution and CVC placement procedures represents therefore an essential tool to enhance performance and reduce intraoperative and long-term CVC complications. Internal jugular vein (IJV) catheterization techniques are different according to ultrasound probe position in relation to vein axis and to needle direction in relation to ultrasound beam...

BACKGROUND: Accurate assessment of cardiac output (CO) is essential for the hemodynamic assessment of aortic valve area (AVA). Estimation of oxygen consumption (VO2) and Thermodilution (TD) is employed in many cardiac catheterization laboratories (CCL) given the historically cumbersome nature of direct continuous VO2 measurement, the "gold standard" for this technique. A portable facemask device simplifies the direct continuous measurement of VO2, allowing for relatively rapid and continuous assessment of CO and AVA...

Femoral artery injuries are a rare complication of blunt trauma in children that require expeditious diagnosis and treatment to prevent permanent limb dysfunction. Point-of-care ultrasonography of femoral vessels is a well-established emergency physician technique for ruling out deep vein thrombosis and guiding femoral vessel catheterization. We present the first report of a pediatric emergency physician diagnosing a traumatic femoral artery thrombus using point-of-care ultrasonography.

An emergency thoracotomy may be life-saving by achieving four goals: (i) releasing cardiac tamponade, (ii) controlling haemorrhage, (iii) allowing access for internal cardiac massage and (iv) clamping the descending aorta to isolate circulation to the upper torso in damage control surgery. We theorize that a new goal should be achieving rapid, large-volume fluid resuscitation and we describe a technique to achieve this.

BACKGROUND: Procedural teaching and the ability to detect and correct errors are important components of surgical education. This study evaluates whether review of an instructional video will improve residents' ability to detect errors. We hypothesized that clinical experience and confidence do not correlate with ability to detect errors. METHODS: Participants were randomized to 2 groups: the study group viewed an instructional video demonstrating correct technique, whereas the control group did not view the instructional video...

Inadvertent complications of jugular vein catheterization are not uncommon, however, a persistent symptomatic carotid-jugular fistula has been rarely reported. A 72-year-old male with infected surgical wound after coxofemoral disarticulation for sarcoma presented with symptoms of acute right heart failure. A fistula between the right common carotid artery (CCA) and the internal jugular vein was demonstrated on Doppler ultrasound and confirmed on computed tomography angiogram. Catheterization of the right CCA seemed not possible using a conventional femoral approach due to the tortuosity and elongation of the brachiocephalic artery...

BACKGROUND: Continuous epidural analgesia with catheterization is a useful technique, because it has a wide adaptation range and provides prolonged analgesia. Problems that may arise from long-term epidural analgesia are changes in the analgesic area, duration of analgesia and catheter-related problems. Few articles have evaluated gradual changes of long-term epidural analgesia. In the animal models used in those studies, the catheter was inserted by an invasive surgical procedure. In the present study, we evaluated changes in a canine model in which the catheter was inserted by a minimally invasive procedure...

BACKGROUND: There has been an increasing use of transpedal arterial access (TPA) for evaluation and treatment of peripheral arterial disease (PAD) over a transfemoral approach (TFA). TPA, it is expected to be associated with better patient comfort, less recovery time and possibly less access site complications compared to standard TFA. Access site complications and pseudoaneurysm (PSA) associated with the TPA have not been previously reported. OBJECTIVE: Here we report a series of pedal artery PSA related to access site complicating TPA catheterization...

Automated blood sampling through a vascular catheter is a frequently utilized technique in laboratory mice. The potential immunological and physiological implications associated with this technique have, however, not been investigated in detail. The present study compared plasma levels of the cytokines IL-1β, IL-2, IL-6, IL-10, IL-17A, GM-CSF, IFN-γ and TNF-α in male NMRI mice that had been subjected to carotid artery catheterization and subsequent automated blood sampling with age-matched control mice. Body weight and histopathological changes in the surgical area, including the salivary glands, the heart, brain, spleen, liver, kidneys and lungs were compared...

BACKGROUND: The external jugular vein (EJV) approach for totally implantable venous access devices (TIVADs) is safe. However, the success rate is unsatisfactory because of the difficulty in catheterization due to the acute angle between the EJV and the subclavian vein (SCV). A novel "shrug technique" to overcome this difficulty was developed, and its efficacy was assessed in a consecutive case series. METHODS: TIVAD placement was performed via the EJV cut-down approach...

BACKGROUND: Laboratory analysis of coagulation is often important in emergencies. If vascular access is challenging, intraosseous catheterization may be necessary for treatment. We studied the analysis of coagulation parameters in intraosseous aspirate during stable conditions and after major haemorrhage in a porcine model. METHODS: Ten anesthetized pigs received central venous and intraosseous catheters and samples were taken for analysis of thromboelastography (TEG), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen concentration...
