BACKGROUND: Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and to clarify the sustained long-term effects of surgery by comparing preoperative, postoperative, and long-term follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for a mean (median) period of 6.8±5.4 years (4.2 years). METHODS: We retrospectively reviewed 27 surgical embolectomy cases for massive or submassive acute PTE from 2003 to 2016. Immediate and long-term follow-up outcomes of surgical embolectomy were assessed on the basis of 30-day mortality, long-term mortality, postoperative complications, right ventricular systolic pressure, and tricuspid regurgitation grade. RESULTS: The 30-day and long-term mortality rates were 14.8% (4 of 27) and 4.3% (1 of 23), respectively. Three patients had major postoperative complications, including hypoxic brain damage, acute kidney injury, and endobronchial bleeding, respectively (3.7% each). Right ventricular systolic pressure (median [range], mm Hg) decreased from 62.0 (45.5–78.5) to 31.0 (25.7–37.0, p<0.001). The tricuspid valve regurgitation grade (median [range]) decreased from 1.5 (0.63–2.00) to 0.50 (0.50–1.00, p<0.05). The improvement lasted until the last echocardiographic follow-up. CONCLUSION: Surgical embolectomy revealed favorable mortality and morbidity rates in patients with acute massive or submassive PTE, with sustained long-term improvements in cardiac function.

Intraoperative pulmonary thromboembolism is a high mortality situation. Early mortality in patients with pulmonary thromboembolism varies from 2% in normotensive patients to 30% in patients with cardiogenic shock. The use of extracorporeal cardiopulmonary resuscitation can improve survival and neurologic outcomes of cardiac arrest. We report a case of intraoperative massive pulmonary thromboembolism with circulatory collapse and cardiac arrest during anesthesia for pelvic bone fracture surgery, which were rescued by extracorporeal membrane oxygenation.

“Thrombus-in-transit” in pulmonary embolism is associated with high mortality and refers to a free-floating clot in the right atrium or right ventricle, indicating that deep vein thrombosis is present en route to the pulmonary artery. Thrombus entrapped in a patent foramen ovale (PFO) is a rare condition and is associated with paradoxical systemic embolism. Here, we report a case of acute pulmonary embolism with thrombus-in-transit through a PFO in a 68-year-old woman with a diagnosis of metastatic pancreatic cancer undergoing palliative chemotherapy. She presented with syncope after acute onset of exertional dyspnea and was diagnosed with cardiogenic shock due to massive pulmonary embolism with thrombus-in-transit on admission to the emergency room. We treated her with systemic thrombolysis and anticoagulation therapy instead of surgical thrombectomy. We show that hemodynamically unstable pulmonary embolism with thrombus-in-transit entrapped by a PFO may be successfully treated with systemic thrombolysis without paradoxical embolism.

Mesenteric venous thrombosis has a low prevalence and nonspecific clinical symptoms, and it may cause bowel infarction and death. Early diagnosis and prompt surgical intervention with anticoagulants are important to patients. We examined a 27-year-old woman complaining of diffuse abdominal pain and hematochezia, and diagnosed extensive mesenteric venous thrombosis with intestinal infarction and pulmonary thromboembolism. In light of the patient's symptoms, an operation seemed necessary. However, because of the high risk of mortality, we decided to look for another option. The patient was successfully treated with intensive medical care and a radiological procedure in spite of intestinal infarction.

BACKGROUND: The treatment of malignant pleural mesothelioma (MPM) is challenging, and multimodal treatment including surgery is recommended; however, the role of surgery is debated. The treatment outcomes of MPM in Korea have not been reported. We analyzed the outcomes of MPM in the context of multimodal treatment, including surgery. METHODS: The records of 29 patients with pathologically proven MPM from April 1998 to July 2015 were retrospectively reviewed. The treatment outcomes of the surgery and non-surgery groups were compared. RESULTS: The overall median survival time was 10.6 months, and the overall 3-year survival rate was 25%. No postoperative 30-day or in-hospital mortality occurred in the surgery group. Postoperative complications included tachyarrhythmia (n=4), pulmonary thromboembolism (n=1), pneumonia (n=1), chylothorax (n=1), and wound complications (n=3). The treatment outcomes between the surgery and non-surgery groups were not significantly different (3-year survival rate: 31.3% vs. 16.7%, respectively; p=0.47). In a subgroup analysis, there was no significant difference in the treatment outcomes between the extrapleural pneumonectomy group and the non-surgery group (3-year survival rate: 45.5% vs. 16.7%, respectively; p=0.23). CONCLUSION: Multimodal treatment incorporating surgery did not show better outcomes than non-surgical treatment. A nationwide multicenter data registry and prospective randomized controlled studies are necessary to optimize the treatment of MPM.

Diffuse alveolar hemorrhage (DAH) is a rare manifestation of trauma or long bone fracture. A relationship between fat embolism and DAH has been reported. A 73-year-old female developed sudden cardiac arrest during a femur fracture operation. Cardiopulmonary resuscitation (CPR) was repeated for about 130 minutes. During CPR, blood was detected in the endotracheal tube. Diffuse patch ground glass opacity appearance and increased pulmonary artery with bulging of interventricular septum toward the left ventricle were detected on a chest computed tomography scan. After full supportive care including ventilator therapy, the patient's condition became stabilized and she was extubated after 7 days. We report a case of DAH in the course of a suspected fat embolism during femur fracture operation. Although DAH is a rare manifestation of fat embolism, early diagnosis and aggressive treatment likely can decrease morbidity and mortality.

Idiopathic venous thromboembolism (VTE) and pulmonary embolism (PE) are relatively infrequent in the pediatric population but are almost always associated with an underlying disease or risk factors, such as congenital or acquired coagulation abnormalities, autoimmune disorders, or malignancies. In the pediatric emergency department, VTE, and particularly, PE, are often less considered in differential diagnoses because of their low incidence. On the other hand, a delayed diagnosis can result in serious morbidity and mortality. Therefore, even if there are no well-known risk factors, it is important to consider the possibility of PE, whenever there are suspicious symptoms and signs. The transposition of the inferior vena cava (IVC) is one of the major anatomical variants among the spectrum of IVC malformations. Although most IVC malformations are clinically silent and are discovered incidentally on radiographs, they are associated with PE in rare cases. In the pediatric population, no cases of transposition of the IVC that was discovered by acute PE have been reported. We report a case of acute PE associated with a transposition of the IVC in a 14-year-old boy without intra-cardiac anomalies or coagulation abnormalities.

BACKGROUND/AIMS: Despite increasing interest in pulmonary thromboembolism (PTE), data on recent trends in PTE incidence are limited. This study evaluated the recent incidence rate of PTE. METHODS: We performed a retrospective chart review of patients with PTE admitted to Chung-Ang University Hospital during the 10-year period from 2006 to 2015. Age-standardized incidence and mortality rates were calculated by the direct method per 100,000 populations. To analyze the trend of risk factor, we also calculated the proportions of cancer, major operation, and recent major fracture over that time. RESULTS: Total crude incidence rate of PTE per 100,000 was 229.36 and the age-sex adjusted standardized incidence rate was 151.28 (95% confidence interval [CI], 127.88 to 177.10). The incidence rate have been significantly increased 1.083 times annually from 2006 (105.96 per 100,000) to 2015 (320.02 per 100,000) (95% CI, 1.049 to 1.118; p < 0.001). These incidences also increased annually in age group of 35 to 54, 55 to 74, and ≥ 75 years, and in both males (odds ratio [OR], 1.071; 95% CI, 1.019 to 1.127; p = 0.007) and females (OR, 1.091; 95% CI, 1.047 to 1.136; p < 0.001). Cancer accounted for most of the increase from 20.0% at 2006 to 2007 to 42.8% at 2014 to 2015 (OR, 1.154; 95% CI, 1.074 to 1.240; p < 0.001), while the proportions of recent fracture and major operation remained constant. CONCLUSIONS: The incidence of pulmonary embolism has gradually increased over the 10 years. The increase of PTE incidence was mainly due to increased proportion of cancer patients.

BACKGROUND: Deep vein thrombosis (DVT) and pulmonary embolism (PE) are conditions with significant morbidity and mortality. Proximal DVT has a significant association with PE and possible fatal outcomes. Traditionally, PE is subdivided into symptomatic PE and asymptomatic PE, which have different treatments, preventions and prognoses. The growing utilization of computed tomography pulmonary angiography has led to increased detection of PE in DVT patients. This study examined the clinical characteristics and compared symptomatic PE and asymptomatic PE following proximal DVT. METHODS: The medical records of 258 DVT inpatients from July, 2012 to June, 2015 were reviewed retrospectively. After excluding the patients who did not performed PE evaluation and were not diagnosed with PE, 95 patients diagnosed with PE following proximal DVT were enrolled in this study. They were divided into the symptomatic PE group and asymptomatic PE group. RESULTS: The body weight, body mass index, thrombus size, thrombus length and location were similar in the two groups. The symptomatic PE following proximal DVT group showed an older age, higher incidence of emergency department access (85.0% vs. 38.7%, p < 0.001) and preceding infection (25.0% vs. 1.3%, p < 0.001) as well as a higher incidence of immobilization (45.0% vs 13.3%, p=0.016). In the multivariate logistic regression study, preceding infection and emergency department access showed significant association with symptomatic PE. CONCLUSION: In proximal DVT inpatients, symptomatic PE was associated with emergency department access and preceding infection. The possibility of a symptomatic PE event should be considered in proximal DVT patients, especially those who were admitted through the emergency department and had preceding infection.
