Current challenges in diagnostic imaging of venous thromboembolism.

Hematology Am Soc Hematol Educ Program 2015 ;2015:202-9

Department of Thrombosis and Hemostasis, Leiden University Medical Center, Leiden, The Netherlands.

Because the clinical diagnosis of deep-vein thrombosis and pulmonary embolism is nonspecific, integrated diagnostic approaches for patients with suspected venous thromboembolism have been developed over the years, involving both non-invasive bedside tools (clinical decision rules and D-dimer blood tests) for patients with low pretest probability and diagnostic techniques (compression ultrasound for deep-vein thrombosis and computed tomography pulmonary angiography for pulmonary embolism) for those with a high pretest probability. This combination has led to standardized diagnostic algorithms with proven safety for excluding venous thrombotic disease. At the same time, it has become apparent that, as a result of the natural history of venous thrombosis, there are special patient populations in which the current standard diagnostic algorithms are not sufficient.

Aviat Space Environ Med 2014 Jul;85(7):730-9

Since its initial introduction into the bedside assessment of the trauma patient via the Focused Assessment with Sonography for Trauma (FAST) exam, the use of point-of-care ultrasound has expanded rapidly. A growing body of literature demonstrates ultrasound can be used by nonradiologists as an extension of the physical exam to accurately diagnose or exclude a variety of conditions. These conditions include, but are not limited to, hemoperitoneum, pneumothorax, pulmonary edema, long-bone fracture, deep vein thrombosis, and elevated intracranial pressure. Read More

Non-invasive intracranial pressure monitoring with transcranial Doppler in a patient with progressive cerebral venous sinus thrombosis.

J Neuroimaging 2014 May-Jun;24(3):302-4. Epub 2012 Dec 10.

Division of Neurology, National University Hospital, Singapore.

In many intracranial disease states, monitoring of intracranial pressure (ICP) is essential to evaluate response to the therapeutic measures as well as estimation of prognosis. Although, direct estimation of ICP is reliable, it is invasive and not possible in all patients. Transcranial Doppler (TCD) ultrasonography is a bedside and noninvasive technique that provides reliable and real-time information about cerebral hemodynamics. Read More

Accuracy in diagnosing deep and pelvic vein thrombosis in primary care: an analysis of 395 cases seen by 58 primary care physicians.

Dtsch Arztebl Int 2012 Nov 9;109(45):761-6. Epub 2012 Nov 9.

Department of General Practice, Düsseldorf University, Germany.

Background: Ruling out a deep vein thrombosis (DVT) is difficult in general practice because the clinical manifestations of DVT are nonspecific and more often due to other diseases. The aim of diagnostic screening in primary care must be to rule out a DVT with high accuracy in most patients, so that only those who are likely to have a DVT will undergo further testing. In this study, we tested the accuracy of exclusion of DVT by the combination of a clinical score (the Wells score) with either a bedside D-dimer test or selective compression sonography. Read More

Accuracy of emergency physician-performed ultrasonography in the diagnosis of deep-vein thrombosis: a systematic review and meta-analysis.

Thromb Haemost 2013 Jan 8;109(1):137-45. Epub 2012 Nov 8.

Department of Clinical Medicine, ASO S. Croce e Carle, Cuneo, Italy.

Duplex ultrasound is the first-line diagnostic test for detecting lower limb deep-vein thrombosis (DVT) but it is time consuming, requires patient transport, and cannot be interpreted by most physicians. The accuracy of emergency physician-performed ultrasound (EPPU) for the diagnosis of DVT, when performed at the bedside, is unclear. We did a systematic review and meta-analysis of the literature, aiming to provide reliable data on the accuracy of EPPU in the diagnosis of DVT. Read More

Predictive value of bedside clinical signs and symptoms in early diagnosis of deep vein thrombosis in acutely ill medical patients with special reference to deep vein thrombosis prophylaxis.

J Indian Med Assoc 2012 Apr;110(4):218-23

Department of General Medicine, NRS Medical College and Hospital, Kolkata 700014.

Deep vein thrombosis (DVT) is highly elusive in the sense, that being so common among acutely ill hospitalised patients with multiple risk factors yet remain mostly unrecognised particularly at the early stage. Pulmonary thrombo-embolism (PTE), the most sinister acute complication of DVT carries a high mortality on one hand and involves expensive medicare and investigations on the other hand. Many studies that have been undertaken in recent past on this important clinical issue have produced a wealth of published data to show that in the absence of prophylaxis for DVT in such a setting the mortality rates were significantly high.

Sonographic diagnosis of pulmonary embolism with cardiac arrest without major dilation of the right ventricle or direct sign of lower limb venous thrombosis.

J Clin Ultrasound 2012 Oct 16;40(8):529-33. Epub 2011 Aug 16.

Department of Emergency Medicine, San Luigi Gonzaga University Hospital, Torino, Italy.

Bedside focused echocardiography diagnosis of massive pulmonary embolism during cardiac arrest is mainly based on the detection of a dilated right ventricle, while the lack of compressibility of a deep vein of the lower limbs confirms diagnosis in doubtful cases. We describe a case of unusual sonographic signs in a young woman with cardiac arrest due to massive pulmonary embolism showing spontaneous blood echogenicity in the inferior vena cava ("sludge sign") and nonmodulated ("flat") Doppler waveform in the left lower limb veins, suggesting isolated iliac vein thrombosis.
