Filter by:Vertebra is one of the most common site of metastatic disease, which may cause severe pain or neurological deficit. Debulking surgery usually has better local control and survival benefit as compared with decompression or radiotherapy. However, debulking surgery often accompany with massive blood loss, which may cause hemorrhagic shock or death. The major bleeding point during operation including tumor parenchyma, arteries that are difficult to ligate, and epidural venous plexus. Vascularity of tumor parenchyma had been associated with increased intraoperative blood loss, on the other hand, there is a lack in the literature regarding to evaluation of the size, flow and pressure of epidural venous plexus, and their changes after embolization.
The investigators aim to evaluate the utility of portal vein pulsatility as a predictor of the composite outcome of persistent organ dysfunction plus death in patients undergoing elective or urgent pulmonary endarterectomy for thromboembolic pulmonary hypertension. The investigators' hypothesis is that the portal vein pulsatility fraction, measured using transesophageal echocardiography immediately after weaning of cardiopulmonary bypass, is proportional to the risk of developing subsequent end-organ dysfunction in the postoperative setting.
The goal of this study is to test MUSTCOOL, a home-based self-monitoring and self-management ulcer prevention intervention for patients with newly healed chronic venous leg and diabetic foot ulcers. Almost 90% of ulcers recur within 3 months of healing. During the six-month randomized clinic trial, skin temperature will be monitored daily, a maintenance dose of cooling gel pack or placebo will be applied three times weekly to the affected skin, and a bolus dose of cooling will be applied for 5 consecutive days if skin temperature becomes elevated. Outcomes on the incidence of leg ulcer recurrence, pain, physical activity and quality of life will be measured.
