Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a means of providing cardiopulmonary support that is being increasingly used in patients with acute heart failure. When ECMO cannulae are placed peripherally, their large diameters pose a risk of limb ischemia. Distal perfusion cannulae (DPC) have been proposed as means to reduce risk, but their use is not recommended by the most recent ECMO guidelines. We sought to establish their utility at our institution. ⋯ Limb ischemia portends a poor outcome in VA-ECMO patients, and prophylactic DPC placement significantly reduces the risk of limb ischemia. We propose prophylactic DPC placement be considered in patients requiring peripheral VA-ECMO.

Thirty-year experience of transaxillary resection of first rib for thoracic outlet syndrome.
Thoracic outlet syndrome is an important clinical entity, which usually affects young patients and working cohort, causing disability if unrecognized and untreated. Although treatment is commonly conservative, in patients with more severe disease, surgical treatment is often required for decompression. Purpose of this paper was to evaluate the surgical and clinical outcomes of patients who underwent first rib resection through transaxillary approach for thoracic outlet syndrome (TOS) during a period of 30 years. ⋯ In our experience first rib resection through the transaxillary approach is a safe and feasible procedure associated with an acceptable rate of peri-operative morbidity and satisfactory long-term relief of symptoms.

The purpose of the following research was to provide a systematic survey on the use of additive manufacturing in vascular surgery. The survey focuses on applications of 3D printing in endovascular surgery like endovascular aneurysm repair (EVAR), a quite unexplored application domain. 3D printing is an additive production process of three-dimensional objects starting from a three-dimensional digital model. This kind of manufacturing process is getting great attention in the medical field and new applications have emerged in recent years especially thanks to the combination of additive printing with 3D imaging techniques. The purpose of the study is to reflect on additive manufacturing and its potential as an inclusive manufacturing practice which can provide benefits at economic and societal level. ⋯ Different applications of the use of 3D printing and digital imaging in vascular surgery have been experimented with a different maturity level. Whilst the technology has increased its potential in the latest years, the number of studies documented in the literature is still quite narrow. Further research is necessary to fully test the potential of 3D printing, also in combination with other technologies (e.g. 3D imaging and CNC cutting). Early experimentations show that these technologies have the potential to radically change the vascular surgery practice in the near future, in particular in treatment like EVAR, to improve the planning and therefore the success of the surgery.

The aim of this study was to determine the level of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in patients with acute pulmonary embolism (APE) according to high and low risk for early mortality based on simplified Pulmonary Embolism Severity Index (sPESI). In addition, it was investigated the relationship between PLR and NLR with systolic pulmonary artery pressure (sPAP), cardiac markers, disease severity and hospital, 1th month, 3th month and 3-month total mortality. ⋯ PLR and NLR increased in patients with high risk, and PLR may have predicting value for 3-month mortality while NLR may have predicting value for hospital mortality, 3th month mortality and total 3-month mortality in patients with APE.

Lower extremity edema occurs in many conditions including congestive heart failure, lymphedema, diabetes-related, kidney and liver disease, chronic venous insufficiency with venous hypertension. Clinical edema assessment methods are often subjective and variable. Our goals were to introduce a simple noninvasive measurement procedure potentially useful to characterize lower extremity edema by providing normative values from which edema thresholds might emerge. ⋯ This assessment method together with the normative ratios and calculated thresholds may aid in rapid detection of lower extremity edema in patients and possibly as a way to quantitatively track changes in edema status with time or treatment. However, the suitability of these thresholds is subject to future validation in persons with clearly defined lower extremity edema for which this report's findings serve as an initial quantitative starting point.
