OBJECTIVE: Pulmonary artery sarcoma is an exceedingly rare malignancy. There is a lack of consensus regarding its diagnosis and treatment. We reviewed our experience in the surgical management of pulmonary artery sarcoma over an 11-year period. METHODS: From January 2005 to February 2016, 12 patients with pulmonary artery sarcoma (age 51 ± 14 years, 5 male) underwent surgical treatment at our center. Nine patients (75%) exhibited pulmonary trunk involvement on computed tomography angiography...

BACKGROUND: Patent foramen ovale (PFO) in patients with acute pulmonary embolism (PE) represents a risk factor for mortality, but this has not been evaluated for CT pulmonary angiography (CTPA). The purpose of the present study was to assess the relationship between PFO and mortality in patients with acute PE diagnosed on CTPA. MATERIALS AND METHODS: This retrospective study included 268 adults [173 women, mean age 61 (range 22-98) years] diagnosed with acute PE on non-ECG-gated 64-slice CTPA in 2012 at our medical center...

PURPOSE: In this study, we describe our experience of lesion marking with fiducial markers (FM) and microcoils (MC) facilitating same-day surgical wedge resection, including success rates, pathology outcomes, and complications. We also explored patient/nodular characteristics associated with developing complications. MATERIALS AND METHODS: An IRB-approved single-institutional retrospective study of 136 patients who had 148 pulmonary nodules was conducted. All patients had CT-guided pulmonary nodule labeling with either FM (121) or MC (15) patients with plan for same-day fluoroscopic-guided wedge resection...

Risk assessment for pulmonary embolism (PE) currently relies on physician judgment, clinical decision rules (CDR), and D-dimer testing. There is still controversy regarding the role of D-dimer testing in low or intermediate risk patients. The objective of the study was to define the role of clinical decision rules and D-dimer testing in patients suspected of having a PE. Records of 894 patients referred for computed tomography pulmonary angiography (CTPA) at a University medical center were analyzed. The clinical decision rules overall had an ROC of approximately 0...

BACKGROUND: Right ventricular (RV) dysfunction caused by acute pulmonary embolism (PE) is associated with poor short- and long-term prognosis. RV dilatation as a proxy for RV dysfunction can be assessed by calculating the right-to-left ventricle diameter (RV/LV) ratio on standard computed tomography pulmonary angiography (CTPA) images. It is unknown whether dedicated training is required to accurately and reproducibly measure RV/LV ratio therefore we aimed to assess these parameters in residents in internal medicine without experience in CTPA reading...

Necrosis of the fat adjacent to the heart, referred to as pericardial fat necrosis, epipericardial fat necrosis, and mediastinal fat necrosis, is a rare, self-limited condition. It presents as a sudden onset of severe chest pain that mimics symptoms of pulmonary embolism and acute coronary syndrome. Computed tomography (CT) findings are quite typical and consist of a round- or oval-shaped mass-like lesion containing soft tissue and fat density components in the cardiophrenic space. Lack of familiarity with this condition has led in the past to surgical interventions to remove the mass-like mediastinal fat necrosis...

BACKGROUND: Bolus tracking is commonly applied in computed tomography pulmonary angiography. The time that it takes for contrast to reach a predefined threshold in the pulmonary artery is called time to threshold (TTT). TTT could be associated with the circulatory state, and ultimately with prognosis in patients with PE. AIM: The purpose of the present study was to examine the correlation of TTT with embolus burden, radiological and clinical parameters of circulatory state, and ultimately with 30-day mortality...

OBJECTIVES: To assess the effects of submassive pulmonary embolism (SMPE) on right atrial (RA) anatomy and function. BACKGROUND: Right ventricular dysfunction (RVD) is associated with adverse outcomes in SMPE. However, the effects of SMPE on the structure and function of the RA have received much less attention. METHODS: Fifty patients with SMPE documented by CT angiography (SMPE group) and evidence of RVD on two-dimensional echocardiography were retrospectively identified and compared to 50 controls (control group)...

A 40-year-old male patient underwent radiofrequency catheter ablation for symptomatic paroxysmal atrial fibrillation (AF). Although pulmonary vein (PV) isolation was successfully completed without acute complications, the patient began complaining of sustained retrosternal pain. Seventeen days after ablation, the patient visited the emergency room with fever and severe chest pain with pericarditis-like features. Chest computed tomography (CT) revealed clustered air bubbles in the pericardial space. Esophagography confirmed leakage of contrast agent into the pericardial space but not into the left atrium...

BACKGROUND: Rates of total hip arthroplasty (THA) are projected to increase in the coming decades. Multiple studies have focused on identifying risk factors for adverse events after joint arthroplasty, and recent attention has been directed toward cancer. Very limited data have been published examining the effects of history of malignancy on outcomes after THA. With a concomitant increase in breast cancer diagnosis and treatments in recent years, it is expected that orthopedic surgeons will likely see more breast cancer survivors in clinic...

BACKGROUND: Guidelines suggest anticoagulation of patients with high pretest probability of pulmonary embolism (PE) while awaiting diagnostic test results (preemptive anticoagulation). Data relevant to the practice of preemptive anticoagulation are not available. METHODS: We reviewed 3,500 consecutive patients who underwent CT pulmonary angiography (CTPA) at 2 emergency departments (ED). We classified the pretest probability for PE using the Revised Geneva Score (RGS) as low (RGS 0-3), intermediate (RGS 4-10), or high (RGS 11-18)...

Mortality associated with high-risk pulmonary embolism (PE) remains high. Extra-corporeal membrane oxygenation (ECMO) allows for acute hemodynamic stabilization and potentially for administration of other disease process altering therapies. We sought to compare two eras: pre-ECMO and post-ECMO in relation to high-risk PE treatment and mortality. A single-center retrospective chart review was conducted of high-risk PE patients. High-risk PE was defined as acute PE and cardiac arrest or shock. A total of 60 patients were identified, 31 in the pre-ECMO era and 29 in the post-ECMO era...
