Venous thrombosis, resulting from a hypercoagulable state, is a vascular complication of AP. AP complicated by pulmonary embolism(PE) is very rare, and the combined use of extracorporeal membrane oxygenation(ECMO) with a vascular interventional procedure for AP complicated by PE is even rarer.CASE SUMMARY A 32-year-old man with a history of obesity developed rapidly worsening AP secondary to hypertriglyceridemia. During treatment, the patient developed chest tightness, shortness of breath, and cardiac arrest. Computed tomography(CT) scans of his upper abdomen were consistent with pancreatitis. PE was identified by chest CT angiography involving the right main pulmonary artery and multiple lobar pulmonary arteries. The patient’s D-dime level was significantly elevated(> 20 mg/L). The patient received high-frequency oxygen inhalation, continuous renal replacement therapies, anti-infective therapy, inhibition of pancreatic secretion, emergent endotracheal intubation, and advanced cardiac life support with cardiopulmonary resuscitation. Following both ECMO and a vascular interventional procedure, the patient recovered and was discharged.CONCLUSION PE is a rare but potentially lethal complication of AP. The early diagnosis of PE is important because an accurate diagnosis and timely interventional procedures can reduce mortality. The combined use of ECMO with a vascular interventional procedure for AP complicated by PE can be considered a feasible treatment method. A collaborative effort between multiple teams is also vital.展开更多

The legalization of marijuana in an increasing number of states has also resulted in an increase in a number of complications related not just to marijuana, but in particular, to SC. As a result, there have been recent increased reports of acute pulmonary injury related to inhaled SC products. We describe that rarely endotracheal intubation with mechanical ventilation has been required to treat the acute respiratory distress syndrome (ARDS) and the diffuse alveolar hemorrhage (DAH) associated with the acute toxicity of SC inhalation. We describe the second reported case of successful utilization of mechanical ventilation and extracorporeal membrane oxygenation (ECMO) in order to treat acute pulmonary toxicity caused by SC inhalation by a water pipe. While the exact pathophysiology of these interesting and recent pulmonary complications is unknown, the recent increase in exposure to SC via water pipe systems and vaping suggests that there will be many more cases of patients that will require ECMO as a form of life-saving therapy.展开更多

In patients undergoing cardiac surgery, the incidence of TRALI is high;however, the detailed clinical course is unknown.

However, no report has mentioned the potential risks of systemic air embolism through a BVF in patients undergoing extracorporeal membrane oxygenation(ECMO). Positive-pressure ventilation and ECMO support in patients with lung injury can increase the risk of systemic air embolism through a BVF. Increased alveolar pressure, decreased pulmonary venous pressure, and anticoagulation are thought to be the factors that contribute to this complication. Here, we present a case of systemic air embolism in a patient with ECMO and mechanical ventilator support.展开更多

文摘Systemic air embolism through a bronchovenous fistu-la(BVF) has been described in patients undergoing positive-pressure ventilation. However, no report has mentioned the potential risks of systemic air embolism through a BVF in patients undergoing extracorporeal membrane oxygenation(ECMO). Positive-pressure ventilation and ECMO support in patients with lung injury can increase the risk of systemic air embolism through a BVF. Increased alveolar pressure, decreased pulmonary venous pressure, and anticoagulation are thought to be the factors that contribute to this complication.
