“…Even so, the decrease in the total number of runs in DARCA group compared with CCA group, may explain the overall reduction in the amount of radiation to the patient. These findings are consistent with all previous studies, with reductions ranging from 32% to 62% and 50.4% in the current study. Although the current and previous studies have not evaluated operator radiation dose, the reduction of radiation exposure to the operator may be even more significant since the moments of greater radiation exposure are well concentrated in both rotations, when the operator can easily walk away from the X‐ray tube.…”

“…This demographic peculiarity in our patients having an increased resistance to intracoronary flow of contrast led us to modify the injection protocol suggested by the manufacturer from LCA 15 ml at 2.5 ml/s to 24 ml at 4 ml/s and for the RCA from 9 ml at 1.5 ml/s to 12 ml at 4 ml/s, in addition to using 6‐F transfemoral sheaths. Even so, a significant 21% reduction in the amount of contrast medium used was noted in the DARCA group, which represents a smaller decrease than that seen in recent studies, ranging from 41% to 49% . The correlation between contrast media volume, the risk of contrast‐induced acute kidney injury (AKI), and impact on the prognosis of patients has been documented in several studies .…”

“…41 Characteristic for such angiography is that vessels branch off large primary vessels to subsequently smaller ones, and typically without collaterals. 42 The outflow tract of the eyes is different and has a much more diffuse and connected nexus of vessels with variable caliber. 7 The drainage system just distal to the outer wall of the SC is more similar to the honeycomb pattern of a capillary network, 7,43 but its vessels are larger and collapsible depending on the perfusion pressure.…”

PurposeTo quantify regional changes of conventional outflow caused by ab interno trabeculectomy (AIT).MethodsGonioscopic, plasma-mediated AIT was established in enucleated pig eyes. We developed a program to automatically quantify outflow changes (R, package eye-canalogram, github.com) using a fluorescent tracer reperfusion technique. Trabecular meshwork (TM) ablation was demonstrated with fluorescent spheres in six eyes before formal outflow quantification with two-dye reperfusion canalograms in six additional eyes. Eyes were perfused with a central, intracameral needle at 15 mm Hg. Canalograms and histology were correlated for each eye.ResultsThe pig eye provided a model with high similarity to AIT in human patients. Histology indicated ablation of TM and unroofing of most Schlemm's canal segments. Spheres highlighted additional circumferential and radial outflow beyond the immediate area of ablation. Differential canalograms showed that AIT caused an increase of outflow of 17 ± 5-fold inferonasally, 14 ± 3-fold superonasally, and also an increase in the opposite quadrants with a 2 ± 1-fold increase superotemporally, and 3 ± 3 inferotemporally. Perilimbal specific flow image analysis showed an accelerated nasal filling with an additional perilimbal flow direction into adjacent quadrants.ConclusionsA quantitative, differential canalography technique was developed that allows us to quantify supraphysiological outflow enhancement by AIT.

The incidence of acute kidney failure remains high, due to the multiplication of interventional procedures on subjects at risk. It increases both morbi-mortality in hospitals and in the long term. The identification of patients atriskis primordial in order to implement the preventiv emeasures, whose expansion remains the 'gold standard'. The realization of a coronary angiography in ambulatory care in this type of patient at risk is possible without increasing renal morbidity, under the cover of a good hydration.Introduction: Acute renal failure is a complication that remains common after injection of contrast agent. It increases both morbidity and hospital mortality in the long term. We wanted to carry out a prospective observational study to evaluate the incidence of renal complications (acute renal failure, dialysis) of patients referred as an outpatient in our center for coronary angiography and who have benefited from measures of prevention of renal toxicity as recommended by learned societies. Methodology:We conducted a prospective study at the Yves Le Foll hospital in Saint Brieuc over a period of 4 months from November 2015 to February 2016, in patients admitted on an outpatient basis for coronary angiography who had previously suspended all drugs with nephrotoxic potential and with hydration surrounding the examination. A survey card was developed to collect, after informed consent, sociodemographic data, risk factors, comorbidities, clinical and paraclinical data. All data was entered and analyzed using SPSS software version 18.0.Results: Ninety-eight patients had an ambulatory coronary angiogram during this period. The sex ratio was 3.66 in favor of the male genus with an average age of 65 years. Three-quarters of the population (71%) had at least one risk factor for contrast-induced nephropathy. The mean clearance values before and after coronary angiography were almost similar (80 μmol/l) without significant variation. No impairment of renal function was observed in patients at risk regardless of the amount of contrast injected (range: between 30 and 277 ml). When patients accumulate risk factors for induced nephropathy in the contrast medium, there is an increase in the blood creatinine level with the number of factors but no significant change (p: 0.24) of renal function after iodine injection. Conclusion:The incidence of acute kidney injury remains high, due to the increase of intervention procedures in subjects at risk. The identification of these patients at risk is paramount in order to implement the preventive measures of which volume expansion remains the gold standard. The realization of an outpatient coronary angiography in this type of patient at risk is feasible without increasing renal morbidity with a good hydration.
