indigo-carmine and Acute-Disease

This study sought to prospectively evaluate the safety and efficacy of the Indigo aspiration system in submassive acute pulmonary embolism (PE).. PE treatment with thrombolytics has bleeding risks. Aspiration thrombectomy can remove thrombus without thrombolytics, but data are lacking.. This study was a prospective, single-arm, multicenter study that enrolled patients with symptomatic acute PE ≤14 days, systolic blood pressure ≥90 mm Hg, and right ventricular-to-left ventricular (RV/LV) ratio >0.9. The primary efficacy endpoint was change in RV/LV ratio from baseline to 48 h post-procedure on core lab-adjudicated computed tomography angiography. The primary safety endpoint was a composite of 48-h major adverse events: device-related death, major bleeding, and device-related serious adverse events (clinical deterioration, pulmonary vascular, or cardiac injury). All sites received Institutional Review Board approval.. A total of 119 patients (mean age 59.8 ± 15.0 years) were enrolled at 22 U.S. sites between November 2017 and March 2019. Median device insertion to removal time was 37.0 (interquartile range: 23.5 to 60.0) min. Two (1.7%) patients received intraprocedural thrombolytics. Mean RV/LV ratio reduction from baseline to 48 h post-procedure was 0.43 (95% confidence interval: 0.38 to 0.47; p < 0.0001). Two (1.7%) patients experienced 3 major adverse events. Rates of cardiac injury, pulmonary vascular injury, clinical deterioration, major bleeding, and device-related death at 48 h were 0%, 1.7%, 1.7%, 1.7%, and 0.8%, respectively.. In this prospective, multicenter study the Indigo aspiration system was associated with a significant reduction in the RV/LV ratio and a low major adverse event rate in submassive PE patients. Intraprocedural thrombolytic drugs were avoided in 98.3% of patients. (Evaluating the Safety and Efficacy of the Indigo aspiration system in Acute Pulmonary Embolism [EXTRACT-PE]; NCT03218566).

The accessory pancreatic duct (APD) is the smaller and less constant pancreatic duct. The patency of the APD was investigated clinically in an effort to determine its role in pancreatic pathophysiology. Dye-injection endoscopic retrograde pancreatography (ERP) was performed in 190 cases. In the patients who exhibited filling of the fine branches of the ducts on ERP, contrast medium with indigo carmine was injected into the major duodenal papilla. The patency of the APD was determined by observing the excretion of the dye from the minor duodenal papilla. Of the 123 control cases studied, 41% had a patent APD. According to the shape of the terminal portion of the APD on accessory pancreatogram, it was classified as either the stick type (n = 63), branch type (n = 15), saccular type (n = 15), spindle type (n = 11), or cudgel type (n = 8). In these groups, 49, 0, 27, 82, and 87% of the APD were patent, respectively. The patency of the APD in the patients with acute pancreatitis was 6% (1 of 17). The difference in patency between this group and the control group was significant (p < 0.01). The patency of the APD varies with the shape of the terminal portion of the APD. A patent APD may prevent acute pancreatitis by lowering the pressure in the main pancreatic ducts.

The objective of this study was to evaluate the function of the minor duodenal papilla and to investigate the relationship between the history of acute pancreatitis and individual dorsal pancreatogram findings and the minor papilla function in pancreas divisum.. Eight of the 21 patients with PD diagnosed by endoscopic retrograde cholangiopancreatography had a history of acute pancreatitis (group A), and 13 patients did not (group B). The reaction of pancreatic juice excreted via the minor papilla was evaluated after intravenous administration of secretin, by observing the repulsion of indigo carmine dye scattered on the surface of the minor papilla.. The function of the minor papilla was classified into two types. In 12 patients, all of the pigment on the minor papilla was repelled within 5 min of secretin administration (type I), and in the remaining nine patients it was not (type II). After secretin administration, the pH of the minor papilla surface in type I was significantly higher than that in type II. There was no significant difference between the type I and type II patients in exocrine pancreatic function, as evaluated by a BT-PABA test. In the group A patients, the rate of occurrence of dorsal duct dilation (including changes of the terminal shape) was significantly greater than in the group B patients. The function of the minor papilla in the group A patients was significantly worse than in the group B patients. Outflow obstruction of pancreatic group B patients. Outflow obstruction of pancreatic juice, i.e., "relative stenosis of the minor papilla," was considered to be present in the patients with type II papilla, and, therefore, the patients with type II papilla might suffer from acute pancreatitis resulting from poor drainage of pancreatic juice and excessive pressure in the dorsal duct.. The finding that patients with PD have one of two types of minor papilla will be useful for understanding the condition and selecting the therapeutic plan for individual patients.

In the experiment on mongrel dogs, the absorption of indigo carmine dye after its retroperitoneal administration with 10% dimexide solution into the lymphatic and venous systems was studied. More rapid delivery of a dye into the portal system, including the cases with portal hypertension, and into the lymphatic system was established. A method for retroperitoneal administration of antibiotics with 10% dimexide solution for prevention and treatment of purulent-septic complications in patients with acute appendicitis has been developed. The method was used in 120 patients, the result of treatment is good.
