Purpose. The purpose of this study was to evaluate the feasibility of detecting pulmonary emboli utilizing noncontrast magnetic resonance imaging techniques in patients with known pulmonary embolism. Materials and Methods. Eleven patients were enrolled in a study to evaluate right ventricular function by cardiac MRI in patients diagnosed with acute pulmonary embolism on CT pulmonary angiogram. Cardiac MRI was performed as soon as possible following pulmonary embolism detection. Two independent observers reviewed the precontrast portion of each MRI, scoring right, left, and lobar arteries as positive or negative for PE. The CTs were reviewed and interpreted in the same manner. Results. MRI was obtained on average of 40 hours after the CT. Forty-eight vessels were affected by PE on CT, 69% of which were identified on MRI. All eight pulmonary emboli located in the right or left pulmonary arteries were detected on MRI. Of the 15 pulmonary emboli that were not detected on MRI, 7 were subsegmental, 6 were segmental, and 2 were located in a branch not included in the MRI field of view. Conclusions. Most pulmonary emboli detected on CT were identified on noncontrast MRI, even though our MRI protocol was not optimized for pulmonary artery visualization.

Primary pulmonary angiosarcoma is a rare type of malignant vascular tumour with poor prognosis. Diagnosis is often late due to non-specific symptoms and low clinical suspicion for angiosarcoma. A 72-year-old man presented to hospital with a 6-month history of mild progressive dyspnoea, with associated cough, episodes of presyncope and weight loss. CT pulmonary angiogram (CTPA) was reported as a large saddle pulmonary embolism extending into both the right and left pulmonary arteries. Further Multidisciplinary team meeting (MDM) discussion, and review of CTPA and subsequent investigations revealed a large primary pulmonary artery sarcoma which was later confirmed histology. The patient was referred to the cardiothoracic surgeons and underwent left radical pneumonectomy.

Bone cement implantation syndrome (BCIS) is a rare and potentially fatal perioperative complication of cemented orthopaedics surgery. A CT-pulmonary angiogram and echocardiogram images were acquired from an 88-year-old patient who had a perioperative collapse while undergoing a revision operation for a peri-implant fracture of the right femoral neck. Findings were suggestive of an intracardiac clot connected to a saddle pulmonary artery embolus. Patient also developed disseminated intravascular coagulation. Overall findings were suggestive of bone cement implantation syndrome.

Introduction. Sickle cell hemoglobin D disease (HbSD) is a rare variant of sickle cell disease (SCD). Incidence of pulmonary thromboembolism (PE) and deep venous thrombosis (DVT) in children with HbSD is unknown. PE and DVT are known complications of SCD in adults but have not been reported in the literature in children with HbSD.Case Report. We are reporting a case of a 12-year-old boy with HbSD with acute chest syndrome (ACS) complicated by complete thrombosis of the branch of the right pulmonary artery and multiple small pulmonary artery emboli seen on computed tomography (CT) pulmonary angiogram and thrombosis of the right brachial vein seen on Doppler ultrasound. Our patient responded to treatment with anticoagulant therapy.Conclusion. There are no cases reported in children with HbSD disease presenting as ACS with pulmonary thromboembolism. We suggest that PE should be suspected in patients presenting with ACS who do not show improvement with standard management. CT pulmonary angiogram should be utilized for early diagnosis and appropriate management as there is no current protocol for management of PE/DVT in pediatric patients with SCD.

Abstract Pulmonary embolism is one of the leading causes of maternal mortality despite a low incidence of during pregnancy. We present 32-year-old woman, in the 35 week of first pregnancy, admitted to the Intensive Care Unit with dyspnea, tachycardia, cyanosis. Echocardiography confirmed the presence of embolic material in the main trunk of pulmonary artery, spreading to the right pulmonary artery. D-dimer and troponin T level were elevated, BNP remained within the normal range. The risk in PESI scale was assumed as intermediate high. LMWH therapy was initiated, the patient was constantly monitored. Venous thrombotic disease in lower extremities was excluded by ultrasonography. The treatment was carried out under obstetric supervision. The clinical state gradually improved, the patient was hemodynamically stable. Serial echocardiographic testing, revealed gradual regression of changes in the pulmonary trunk. Normalization of troponins and lowering of BNP levels were observed. The pregnancy was terminated in 39 week, by cesarean section (obstetric indications). The LMWH was continued few days after delivery, as the patient started lactation. She decided to terminate lactation in a first week after delivery so the therapy was switched into rivaroxaban for at least 3 months. Echocardiography after 3 month confirmed lack of changes in pulmonary trunk, the risk of pulmonary hypertension was low. Echocardiography can be a method of choice for confirming and monitoring pulmonary embolism during pregnancy, in a situation of high or intermediate clinical risk and good visualization of changes in pulmonary arteries Abstract P701 Figure.

ObjectiveTo determine the prevalence of syncope or collapse in pulmonary embolism (PE).MethodsA retrospective cohort study was conducted. We examined the frequency with which syncope or collapse (presyncope) occurred alone or with other symptoms and signs in an unselected series of 224 patients presenting to a district general hospital with PE between September 2012 and March 2016. Confirmation of PE was by CT pulmonary angiogram in each case.ResultsOur cohort of 224 patients comprised 97 men and 127 women, average age 66 years with age range of 21–94 years. Syncope or collapse was one of several symptoms and signs that led to a diagnosis of PE in 22 patients (9.8%) but was never the sole presenting feature. In descending order, these other clinical features were hypoxaemia (17 patients), dyspnoea (12), chest pain (9), tachycardia (7) and tachypnoea (7). ECG abnormalities reported to occur more commonly in PE were found in 13/17 patients for whom ECGs were available. Patients with PE presenting with syncope or collapse were judged to have a large clot load in 15/22 (68%) cases.ConclusionSyncope was a frequent presenting symptom in our study of 224 consecutive patients with PE but was never the sole clinical feature. It would be difficult to justify routine testing for PE in patients presenting only with syncope or collapse.

Fatal embolic chondroblastic osteosarcoma to the lung is an extremely rare phenomenon. We report a case of a 15-year-old boy who developed bilateral pulmonary embolism shortly after resection of the right distal femur for chondroblastic osteosarcoma. The patient succumbed to right-sided heart failure 8 weeks later. An autopsy revealed extensive intravascular tumor emboli in the bilateral pulmonary arteries and their branches. No metastatic lesions were identified in the lungs. We review the clinical, radiologic, and pathologic findings of this patient and the literature.

Vena Femoralis Superficialis

A 73-year-old man was admitted with progressive dyspnea; he also had benign prostatic hyperplasia (BPH). An angio computed tomography scan showed pulmonary embolism with thrombi in both main pulmonary arteries. By duplex ultrasonography, we detected a thrombus in the right vena femoralis superficialis and vena femoralis communis. Simultaneously, we also noticed a large diverticulum on the right side of the urinary bladder and urinary stasis II of the left kidney. We consider the BPH as the trigger for a secondary diverticulum of the urinary bladder. As a result of its large dimensions, mechanical compression of the deep right pelvic veins resulted in thrombosis which finally caused the pulmonary embolism. With respect to the urinary stasis II, surgical excavation of the diverticulum with infravesical desobstruction was planned. The potentially lethal course of large diverticula may require surgery.
