Pulmonary Embolism and Pregnancy-Challenges in Diagnostic and Therapeutic Decisions in High-Risk Patients.

Front Cardiovasc Med 2022 8;9:856594. Epub 2022 Mar 8.

Department of Cardiology, University Medical Center of the Johannes Gutenberg-University, Mainz, Germany.

Diagnosis of acute PE in pregnant women with haemodynamic instability is following the general integrated risk-adapted diagnostic algorithm and starts with bedside echocardiography to assess RV function. If RV dysfunction is identified, a prompt and immediate reperfusion without further imaging should be initiated. Although pregnancy is listed as a relative contraindication of systemic thrombolysis, in pregnant women with acute PE and haemodynamic instability thrombolysis must be considered. Read More

Ultrasonographic evaluation of deep vein thrombosis related to the central catheter in hemodialytic patients.

Ultrasound J 2022 Jan 10;14(1). Epub 2022 Jan 10.

Barbacena Medical School, Minas Gerais, Brazil.

Background: Point of care ultrasound (PoCUS) is a useful tool for the early diagnosis of thrombosis related to the central venous catheter for dialysis (TR-CVCd). However, the application of PoCUS is still not common as a bedside imaging examination and TR-CVCd remains often underdiagnosed in the routine practice. The aim of this study was to investigate if a compression technique for the diagnosis of TR-CVCd blindly performed by PoCUS experts and medical students is accurate when compared to a Doppler study.

Vascular access management of hemodialysis patients at the bedside using point-of-care ultrasound.

J Med Ultrason (2001) 2021 Nov 26. Epub 2021 Nov 26.

Department of Urology, Sakaiheisei Hospital, Osaka, Japan.

When vascular access (VA) for hemodialysis is established using an autologous fistula or synthetic graft, repeated damage from needle insertion at each dialysis session can lead to thrombosis, resulting in vascular stenosis or occlusion that can cause poor blood removal, elevated venous pressure, and other impairments of blood flow. Compact, high-performance ultrasound devices have been developed in recent years. Such devices are used for point-of-care ultrasound (POCUS), which has been used on many occasions for emergency evaluation in the dialysis room and is becoming an important tool in VA management.

Labyrinthine haemorrhage secondary to cerebral venous thrombosis.

Eur J Neurol 2021 12;28(12):4258-4260

Neurology Department, Coimbra University and Hospital Centre, Coimbra, Portugal.

Cerebral venous thrombosis (CVT) can rarely present with acute ipsilateral cochlear and/or vestibular loss, to date always in the absence of a clear local otogenic process evidenced by magnetic resonance imaging (MRI). This association has been putatively attributed to inner ear anoxia due to blockage of inner ear venous drainage. We present a nonreported case of thrombosis of the left transverse and sigmoid sinuses presenting with acute unilateral vestibulopathy in which MRI disclosed concurrent ipsilateral labyrinthine haemorrhage.

Point-of-Care Ultrasound for Bedside Diagnosis of Lower Extremity DVT.

Chest 2021 11 13;160(5):1853-1863. Epub 2021 Jul 13.

Department of Medicine, Division of Pulmonary and Critical Care, Hospital of the University of Pennsylvania, Philadelphia, PA.

The point-of-care ultrasound DVT (POCUS DVT) examination can facilitate rapid bedside diagnosis and treatment of lower extremity DVT. Awaiting radiology-performed Doppler ultrasonography and interpretation by radiologists can lead to delays in lifesaving anticoagulation, and the POCUS DVT examination can provide timely diagnostic information in the patient with lower extremity symptoms. This article outlines accepted techniques for the POCUS DVT examination, discusses the historical context from which the current recommendations have evolved, and provides illustrations alongside ultrasound images of relevant venous anatomy to orient the clinician.
