Septic pulmonary emboli rarely cause respiratory failure that requires mechanical ventilation. The most common causes of septic pulmonary emboli are related to intravenous drug abuse, indwelling intravenous catheters, endocarditis and septic pelvic thrombophlebitis. In addition, soft tissue injury-related thrombophlebitis rarely causes septic pulmonary emboli. We describe a unique case of a 43-year-old man who developed septic thrombophlebitis of the femoral vein following soft tissue injury from trauma to the shin with ensuing septic pulmonary emboli which necessitated endotracheal intubation and mechanical ventilation. The patient required mechanical ventilation for eleven days, developed empyema and grew out methicillin-resistant Staphylococcus aureus on blood cultures. A transesophageal echocardiogram was normal, and there was no indication of bacterial endocarditis. In addition to eleven days of mechanical ventilation, the patient was treated with intravenous heparin, cefepime and clindamycin. These medications were then discontinued and the patient was treated with weight-adjusted vancomycin. Following the return of cultures, the patient was treated for six weeks with ceftaroline 600 mg IV twice a day. In addition, the patient received bilateral thoracentesis followed by chest tube drainage until resolution of the pleural effusions. The patient made a complete recovery. We describe this case and the implications for differential diagnosis and treatment of these two uncommon conditions.

Background, Motivation and Objective Neurologic complications, such as transient ischemic attack, stroke and cognitive decline, are common complications after cardiac surgery. They can not only disable patient or take away patient’s life but also cause heavy financial and mental burden upon the patients and their family. The reason of neurologic complications is related to gaseous and solid emboli of head blood vessel which are generated in extracorporeal circulation and surgical operation. Therefore, it is very meaningful to block gaseous and solid emboli from flowing into head from the right common carotid artery. Ultrasound field can generate ultrasonic radiation force acting on embolic and may block emboli from flowing into some blood vessels. This study is aimed to evaluate the blocking effect of the phased array ultrasound on emboli. Statement of Contribution/Methods We did experiments on eight pigs(40kg). After opening thorax, we positioned ultrasound transducer between aorta ascendens and truncus brachiocephalicus. And emboli were detected by PHILIPS CX50 on the right common carotid artery. Air embolic used every time were created by mixing 1 ml air with 9 ml normal saline and polystyrene particles(Duke Corp) dissolved in normal saline as the solid emboli. Both kinds of emboli were injected in the left auricle 8 times on each pig. 4 times with ultrasound transducer off and 4 times with ultrasound transducer on. The emboli which flowed into the right common carotid artery were detected and analyzed. At the end of the experiment, the sonicated tissue was cut for histopathology test. Results The histopathology test showed that the sonicated tissue was not injured. The use of phased array ultrasound significantly reduced the number of emboli which flowed into the right common carotid artery. The gaseous emboli reduced by 69% and the solid emboli reduced by 61%. Discussion and Conclusions The research revealed that use of phased array ultrasound is a safe way to

Monitoring the Sequelae of Coronary Microembolization on Myocardium Using Noninvasive Imaging (Review)

引用

World Journal of Cardiovascular Diseases 2014年第12期4卷 601-622页

Acute myocardial infarction (AMI) is a leading cause of death worldwide. It has been clinically classified into 1) ischemic from a primary coronary event (e.g., plaque rupture or thrombotic occlusion), 2) ischemic from a supply-and-demand mismatch and c) ischemic from a percutaneous coronary interventions (PCI). Catheter-based PCI has been frequently used as an alternative to conventional bypass surgery for patients at high risk. However, this method of treatment is associated with microvascular obstruction (MVO) by dislodged microemboli that results in left ventricular (LV) dysfunction/remodeling, perfusion deficits, microinfarction and arrhythmia. The contributions of microemboli after revascularization of AMI have been acknowledged by major cardiac and interventional societies. Recent studies showed that emboli Detection and Classification (EDAC) Quantifier offers increased sensitivity and capability for detecting dislodged coronary microemboli during PCI. Coronary microembolization can be detected directly by monitoring intra-myocardial contrast opacification on contrast echocardiography, increasing F-18 fluorodeoxyglucose (FDG) uptake on positron emission tomography, loss/diminution of signal on first pass perfusion and hypoenhanced zone on contrast enhanced magnetic resonance imaging (MRI) and multidetector computed tomography (MDCT) and indirectly by ST-segment elevation on electro-cardiography (ECG). The relations between volumes/sizes of microemboli, visibility of microinfarct, myocardial perfusion and LV function are still under intensive discussions. Non-invasive imaging can play important role in assessing these parameters. This review shed the light on the techniques used for detecting coronary microemboli, microvascular obstruction and microinfarct and the short- and long-term effects of microemboli on LV function, structure and perfusion.

Microembolic signal detection by transcranial Doppler: Old method with a new indication

World Journal of Methodology 2018年第3期8卷 40-43页

作者： Sombat Muengtaweepongsa Charturong Tantibundhit Department of Internal Medicine Faculty of Medicine Thammasat University

Transcranial Doppler(TCD) is useful for investigation of intracranial arterial blood flow and can be used to detect a real-time embolic signal. Unfortunately, artefacts can mimic the embolic signal, complicating interpretation and necessitating expert-level opinion to distinguish the two. Resolving this situation is critical to achieve improved accuracy and utility of TCD for patients with disrupted intracranial arterial blood flow, such as stroke victims. A common type of stroke encountered in the clinic is cryptogenic stroke(or stroke with undetermined etiology), and patent foramen ovale(PFO) has been associated with the condition. An early clinical trial of PFO closure effect on secondary stroke prevention failed to demonstrate any benefit for the therapy, and research into the PFO therapy generally diminished. However, the recent publication of large randomized control trials with demonstrated benefit of PFO closure for recurrent stroke prevention has rekindled the interest in PFO in patients with cryptogenic stroke. To confirm that emboli across the PFO can reach the brain, TCD should be applied to detect the air embolic signal after injection of agitated saline bubbles at the antecubital vein. In addition, the automated embolic signal detection method should further facilitate use of TCD for air embolic signal detection after the agitated saline bubbles injection in patients with cryptogenic stroke and PFO.

Hydrogen peroxide ingestion with injury to upper gastrointestinal tract

World Journal of Clinical Cases 2017年第10期5卷 378-380页

作者： Jonathan V Martin Choichi Sugawa Michael and Marian Ilitch Department of Surgery 6-C University Health Center

Hydrogen peroxide is a common over-the-counter solution that has developed a growing body of literature regarding toxic ingestion. Intentional ingestion of high concentration hydrogen peroxide for health purposes has gained popularity in certain patient populations; purported benefits are due to the increased oxygen released into the blood stream. We present for evaluation one such case with associated imaging that presented to our urban medical center. A brief review of the literature was also performed noting current recommendations regarding both outcomes and indications for endoscopy as well as hyperbaric oxygen therapy following ingestion of hydrogen peroxide. Our patient was a 51-year-old white female who presented with foamy hematemesis after ingesting 10 drops of 35% hydrogen peroxide as part of a home remedy to cleanse her colon and improve blood oxygenation. In addition to hematemesis,she also reported diffuse abdominal pain with sore throat and hoarse voice. Her imaging demonstrated portal venous gas and gastric edema. She was admitted for hyperbaric oxygen therapy and underwent upper endoscopy demonstrating diffuse esophagitis and gastritis with white exudate and multiple petechiae. She was later discharged home in stable condition and was lost to follow-up.
