Systemic versus Pulmonary Bleeding in Lung Infection: Value of CT in Two Cases.

Bronchial and pulmonary artery aneurysms are rare causes of hemoptysis in the course of lung infection, for which early diagnosis and treatment are essential to prevent fatal bleeding. Depending on patient condition, these occurrences are amenable to computed tomography (CT) to determine both the cause of hemoptysis and the bleeding site in order to plan the most effective bleeding-control procedure. In this report, we illustrate the importance of the bleeding site identification using CT in two cases of infection-related hemoptysis.

Multicenter, Randomized Trial of Conventional Balloon Angioplasty versus Paclitaxel-Coated Balloon Angioplasty for the Treatment of Dysfunctioning Autologous Dialysis Fistulae.

PURPOSE: To investigate the potential added value of paclitaxel-coated balloon (PCB) angioplasty to reduce fistula dysfunction related to recurrent stenoses in patients undergoing hemodialysis. MATERIALS AND METHODS: A prospective, randomized study was conducted in 3 dialysis referral centers. From January 2013 to October 2015, 64 patients (22 female, 42 male) with dysfunctional autologous dialysis fistulae were randomized to undergo conventional percutaneous balloon angioplasty (n = 31) or PCB angioplasty (n = 33). Procedural and postprocedural data were assessed. Primary patency of the fistula was evaluated at 3, 6, and 12 months following the procedure. Statistical analysis was based on the Fisher exact test and independent t test. RESULTS: There were no procedural or postprocedural complications. After 3, 6, and 12 months of follow-up, primary patency rates after PCB angioplasty and percutaneous transluminal angioplasty (PTA) were 88% and 80% (P = .43), 67% and 65% (P = .76), and 42% and 39% (P = .95), respectively. CONCLUSIONS: Although primary patency rates after PCB angioplasty in autologous dialysis fistulae at 3, 6, and 12 months of follow-up are slightly better than those after PTA, the difference is not statistically significant.

Paclitaxel-Coated Balloon Angioplasty of Venous Stenoses in Native Dialysis Fistulas: Primary and Secondary Patencies at 6 and 12 Months.

PURPOSE: When dialysis access stenoses are dilated by noncoated balloons, respective primary and secondary patencies hardly reach 50 per cent and 85 per cent at one year. This study determines the primary and secondary patency rates at 6 and 12 months for venous stenoses treated by paclitaxel-coated balloon (PCB) angioplasty in native hemodialysis accesses. MATERIALS AND METHODS: From 2012 to 2014, 70 venous stenoses in 41 patients benefited from PCB angioplasties. The patients' mean age was 62.5 ± 13.8 years' standard deviation (SD) with 75 per cent male gender, 31.7 per cent diabetes, and 65.9 per cent arterial hypertension. There were 58.5 per cent forearm fistulas and 41.5 per cent arm fistulas. Primary and secondary patency rates were prospectively established by using the Kaplan-Meier technique and tested by using the log-rank test. RESULTS: The primary patency rates ± SD were 81.4 ± 4.6 per cent and 60 ± 5.9 per cent at 6 and 12 months, respectively. The secondary patency rates ± SD reached 94.3 ± 2.8 per cent at 6 months and 91.4 ± 3.3 per cent at 12 months. CONCLUSION: This study shows an improvement of the primary and secondary patency rates at 6 and 12 months when venous stenoses of native dialysis fistulas are treated by PCB. The indications for PCB, however, remain to be established by larger randomized studies.

Intragastric Rupture of a Splenic Artery Aneurysm Associated with a Pancreatic Cancer.

Acute upper digestive tract hemorrhage most often arises from gastric and esophageal vessels located in the mucosa or the submucosa. Rupture in the upper gastrointestinal tract is a classical but uncommon complication of arterial (mainly the abdominal aorta) aneurysms. Splenic artery aneurysm usually ruptures in the peritoneum, unless it is associated with a disease eroding the gastrointestinal wall. We present and describe the management of the rare occurrence of an intragastric rupture of a splenic aneurysm associated with a pancreatic cancer.
