Background
Pericardial effusion is a common entity which may have important implications in patient’s prognosis. In several cases, pericardiocentesis is indicated for diagnostic and/or therapeutic purposes.
Case presentation
A blind pericardiocentesis failed in a 95-year-old woman admitted to the emergency department with a large pericardial effusion incidentally diagnosed in the ambulatory setting. Ultrasound-guided pericardiocentesis aided in easily accessing to the pericardial cavity, without periprocedural complications.
Conclusions
Ultrasound-guided pericardiocentesis is simple, safe and effective, and should replace the blind technique. This procedure should be part of the armamentarium of ultrasound-guided practices of emergency or critical care physicians.
Background
Traumatic vascular injury of the limbs has the potential to cause substantial patient morbidity and mortality, and therefore, early recognition and treatment are crucial to improve outcomes. While patients with hard signs of arterial injury mandate for an immediate surgical intervention, patients presenting with soft signs of arterial injury need further diagnostic evaluation.
Case presentation
A 24-year-old male was admitted to the emergency department after suffering a stab wound in the anterolateral aspect of his left upper thigh. Entry wound measures approximately 3 cm × 0.7 cm; no exit wound was observed. On examination of the injured limb, the thigh was swollen and painful. Skin color was mildly pale and skin temperature was slightly diminished in his leg; leg numbness was also pointed out by the patient. Common femoral artery pulse was normal, while distal pulses were diminished. Point-of-care Doppler ultrasound (DUS) showed a subfascial hematoma in the thigh, which filled on color Doppler, corresponding to a pseudoaneurysm. On spectral Doppler, signs of distal low blood supply were noted. The patient was immediately transferred to the operating room where a 1-cm laceration was found in the anterior aspect of the superficial femoral artery. The involved artery was successfully repaired and distal flow was reestablished, as assessed by clinical examination, pulse palpation and DUS.
Conclusions
Based on its several advantages, DUS should be considered as the first-line diagnostic tool in the diagnostic workup of patients with soft signs of arterial injury.
Background
Infective endocarditis carries a high morbidity and mortality; therefore, a rapid diagnosis and timely treatment is crucial to improve outcomes. Diagnosis of infective endocarditis is supported on echocardiogram findings.
Case presentation
An adult male with history of long-term hemodialysis, presented with embolic manifestations (cerebral, skin) and fever. A large vegetation in the mitral valve and other in the tricuspid valve were detected by point-of-care transthoracic echocardiogram, while blood cultures subsequently resulted positive for methicillin-resistant Staphylococcus aureus. Despite therapeutic efforts, the patient developed into an irreversible shock and died.
Conclusions
Point-of-care echocardiogram has a pivotal role in diagnosis and decision-making of infective endocarditis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
