Introduction: The aim of this study is to evaluate the outcome of Omniflow II biosynthetic vascular grafts as compared to synthetic expanded polytetrafluoroethylene (ePTFE) grafts in infrainguinal bypass surgery. Methods: A single-center, retrospective, observational study was performed reviewing patients with critical limb ischemia who underwent infrainguinal bypass surgery between 2014 and 2018. Patients characteristics, graft characteristics, and treatment outcomes were collected. Patency rates were compared using Kaplan–Meier estimates. Results: Sixty bypasses were performed in 57 patients. For above-knee surgery, six were Omniflow and 13 were synthetic. For below-knee surgery, 19 were Omniflow and 22 were synthetic. Patient characteristics between groups were similar. However, American Society of Anesthesiologists (ASA) classification scores were higher in the Omniflow group as compared to ePTFE (88% was ASA 3 or higher versus 60%; p = 0.018). Furthermore, wound, ischemia, and foot infection (WIfI) composite scores were higher in the Omniflow group ( p = 0.0001). There was a trend toward more active infection at time of surgery in the Omniflow group (40 vs 22.9%, p = 0.15). At 1 year, primary patency rates were 60.0% versus 46.9% for above-knee Omniflow versus ePTFE grafts, respectively ( p = 0.72). Secondary patency rates were 80.0% versus 82.5% ( p = 0.89), and limb salvage rates were 83.3% versus 100% ( p = 0.14). For below-knee surgery, 1- and 2-year primary patency rates in Omniflow versus ePTFE grafts were 36.0% versus 41.8% ( p = 0.60) and 36.0% versus 31.1% ( p = 0.87). Secondary patency rates were 66.8% versus 75.2% at 1 year ( p = 0.53) and 58.8% versus 48.3% ( p = 0.77) at 2 years. Below-knee limb salvage rates for Omniflow versus ePTFE after 2 years were 88.0% versus 68.3% ( p = 0.28), respectively. Aneurysmal degeneration occurred in 2/25 (8%) in the Omniflow group and 0/35 (0%) in the ePTFE group. Bypass infections occurred in 2/25 (8%) in the Omniflow group and 0/35 (0%) in the ePTFE group ( p = 0.09). Conclusion: Omniflow bypasses were more commonly implanted in patients with higher limb infection rate as confirmed with a higher adapted WIfI score. A trend toward a higher infection rate of Omniflow grafts was observed but not statistically significant. Graft infection rates were relatively low and treatable with antibiotics. No significant difference in graft performance was observed. The choice between the two studied grafts remains based on surgeon’s preference.

Aim. A critical analysis of modern scientific publications on the application in complex treatment program of patients with acute bleeding from esophageal varices endoscopic hemostasis with self-expanding nitinol Danish stents.Methods. Literature data are presented on the results of treating patients at the height of esophageal bleeding or with a high risk of recurrence by installing self-expanding nitinol Danish stents.Results. The advantages of Danish stent include low trauma; good tolerance; physiological saliva drainage and the possibility of receiving fluid and food through the mouth; repeated endoscopic examination of the esophagus and stomach after the introduction of the stent; reducing the risk of aspiration pneumonia; the impossibility of removal or displacement by the patient in a state of excitement. The disadvantages of self-expanding nitinol Danish stents, in addition to the risk of migration from the esophagus to the stomach with loss of its plugging function, include the limitation of the therapeutic effect only to varicose veins of the esophagus, the development of small erosions or ulcers on the mucous membrane of the esophagus after stent removal.Conclusion. The extent to which endoscopic hemostasis with self-expanding nitinol Danish stents will take a strong place in the treatment of patients with variceal bleeding is not clear. In the recommendations of the Baveno VI Consensus the method is considered as an attractive alternative to Sengstaken–Blackmore balloon tamponade, however, the need for confirmation of the initial clinical results by further comparative randomized controlled trials is indicated.

✓ The importance of hemodynamic factors in the pathogenesis and treatment of cerebrovascular disease remains uncertain. The extracranial-intracranial (EC-IC) bypass trial has been criticized for failing to identify and separately analyze those patients with chronic reduction in regional cerebral perfusion pressure (rCPP) who might be most likely to benefit from surgery. Positron emission tomography (PET) measurements of regional cerebral blood flow (rCBF) and blood volume (rCBV) were performed on 29 patients with symptomatic occlusion or intracranial stenosis of the carotid arterial system prior to undergoing EC-IC bypass surgery. Twenty-four patients had evidence of reduced rCPP (increased rCBV/rCBF ratio) distal to the arterial lesion. Of 21 patients who survived surgery without stroke, three suffered ipsilateral ischemic strokes during the 1st postoperative year. A nonrandomized control group of 23 nonsurgical patients with similar clinical, arterio-graphic, and PET characteristics experienced no ipsilateral ischemic strokes during the 1st year following PET. Based on these results in 44 patients, the probability that successful surgery reduces the occurrence of ipsilateral ischemic stroke 1 year later was calculated. This probability ranged from 0.045 for a 50% reduction to 0.168 for a 10% reduction. Thus, there was little evidence to suggest that measurements of cerebral hemodynamics can identify a group of patients who would benefit from EC-IC bypass surgery.
