BACKGROUND AND PURPOSE: Flat panel catheter angiotomography performed during the selective injection of intersegmental arteries offers a multiplanar assessment of the intraforaminal course of the radicular arteries providing an anterior radiculomedullary artery. Injury of anterior radiculomedullary arteries during transforaminal epidural steroid injections can result in spinal cord damage. Evaluations of the intraforaminal location of these arteries have so far been limited to anteroposterior views or the examination of cadaveric material...

The anomalous origin of the entire coronary system from the right coronary sinus is a very rare anomaly. Here a patient with this rare anomaly, who developed acute coronary syndrome, requiring revascularization, is presented and treated successfully. His coronary angiographic findings are also discussed. We would like to highlight the rarity of the origin of all 3 coronary arteries from a single coronary trunk. The case also highlights the importance of using Amplantzer AR1 guiding catheter for such anatomical variations arising in the right coronary cusp...

Aortocoronary dissection is a rare but serious complication. We report the case of a 72-year-old female with angina. Percutaneous coronary intervention was performed for right coronary artery disease. Manipulation of the guiding catheter led to aortocoronary dissection. A drug-eluting stent was immediately implanted in the right coronary ostium to seal the entry of the dissection. Computed tomography (CT) showed ascending aortic dissection. The patient was observed without surgery. CT performed the following day and showed the contrast in the false lumen which had disappeared...

Mechanical ventilation is widely recommended for reptiles during anesthesia, and while it is well-known that their low ectothermic metabolism requires much lower ventilation than in mammals, very little is known about the influence of ventilation protocol on the recovery from anesthesia. Here, 15 ball pythons (Python regius) were induced and maintained with isoflurane for 60min at one of three ventilation protocols (30, 125, or 250ml min(-1)kg(-1) body mass) while an arterial catheter was inserted, and ventilation was then continued on 100% oxygen at the specified rate until voluntary extubation...

PURPOSE: Coronary artery disease involves the deposition of plaque along the walls of a coronary artery leading to narrowed or blocked vessels (stenosis) and is one of the main causes of death in developed countries. Percutaneous transluminal coronary angioplasty (PTCA) is used to reverse stenosis. Restenosis (renarrowing) of the treated vessel is a major complication of PTCA. A metal mesh tube (stent) can be placed inside the vessel to prevent restenosis. Tissue stress incurred during PTCA and stenting can provoke neointimal cell proliferation leading to in-stent restenosis (ISR)...

Calcification of the tunica media of the axial pulmonary arteries (PA) has been reported in a large proportion of racehorses. In humans, medial calcification is a significant cause of arterial stiffening and is implicated in the pathogenesis of cardiac, cerebral and renal microvascular diseases. Pulse wave velocity (PWV) provides a measure of arterial stiffness. This study aimed to develop a technique to determine PA-PWV in horses, and secondarily to investigate a potential association between PA-PWV and arterial fibro-calcification...

EDITORIAL

While oral anticoagulants (OACs) remains the main strategy of prevention of thromboembolic event in patients with atrial fibrillation (AF), left atrial appendage closure (LAAC) has become an alternative recently. The concept of this technique is based on the understanding that in more than 90% non-valvular AF patients, the thrombi form in the left atrial appendage (LAA), so excluding the LAA from the systemic circulation can prevent stroke or peripheral arterial embolization. To achieve this goal, novel trans-catheter techniques have been developed to either occlude the LAA endocardially or ligate the LAA epicardially...

The term nonthrombotic pulmonary embolism (NTPE) is defined as embolization of pulmonary arteries caused by foreign bodies (e. g. detached catheter fragments), biological substances (e. g. septic thrombus) or exogenous substances (e. g. gas). The frequency of NTPE is underestimated. Symptoms can cover the spectrum from undetectable to sudden death. In addition to mechanical obstruction of the pulmonary arteries, some NTPEs trigger an inflammatory cascade that causes deterioration of vascular, pulmonary and cardiac function...

Positron emission tomography with (15)O-labeled gases ((15)O-PET) is important for in vivo measurement of cerebral oxygen metabolism both in clinical and basic settings. However, there are currently no reports concerning (15)O-PET in mice. Here, we developed an (15)O-PET method applicable to mice with spontaneous respiration of (15)O-gas without a tracheotomy catheter. Sequential (15)O-PET was also performed in a mouse model of chronic cerebral hypoperfusion with bilateral common carotid artery stenosis (BCAS) induced by placement of microcoils...

Non-obstructive angioscopy (NOA) is used to visualize the surface of the coronary artery, and a clear visual field is obtained by injecting transparent fluid into the gap between the probing catheter and the fiber. This study examines visual field expansion by a dual infusion method, which involves an infusion from the probing and guiding catheters, and the relationships between visual grade and vessel characteristics. Thirty-two patients and thirty patients performed coronary plaque analysis with NOA using the conventional method and the novel dual infusion method, respectively...

BACKGROUND: Apnea testing is an essential step in the clinical diagnosis of brain death. Current international guidelines recommend placement of an oxygen (O2) insufflation catheter into the endotracheal tube to prevent hypoxemia, but use of a continuous positive airway pressure (CPAP) valve may be more effective at limiting arterial partial pressure of O2 (PO2) reduction. METHODS: We performed a multicenter study assessing consecutive apnea tests in 14 intensive care units (ICUs) in two cities utilizing differing protocols...
