Thrombosis in newborns: experience from 31 cases

Abstract

Thrombosis is the result of congenital or acquired prothrombotic risk factors. The incidence of thrombosis in the paediatric population is highest in newborns, as about 10% of thrombotic events occur in the first four weeks of life. Haemostasis in a newborn, though still developing, is a well balanced mechanism. About 90% of all thrombotic events are due to acquired and the rest to congenital risk factors.
The aim of our study was to estimate the incidence of thrombosis in a population of Slovenian newborns and to study risk factors, location and treatment of thrombotic events.
Inpatient charts of newborns with thrombosis, admitted to a tertiary neonatology centre and paediatric intensive care unit between 2004 and 2011, were studied retrospectively. Family history, location, aetiology and treatment of thrombosis were analysed.
Thirty one newborns, 17 boys (54.8%) and 14 girls (45.2%), with 31 thrombotic events were found. There were 17 cases (54.8%) of arterial and 14 cases (45.2%) of venous thrombosis. A  family history of thrombophilia was found in two cases (6.5%). Twenty six cases (83.9%) were contributed to acquired risk factors and five (16.1%) to congenital aetiology. Four cases (12.8%) were treated, two with anticoagulation, one with thrombolysis and one with both. The estimated incidence of thrombosis was 0.17 per 1000 live births. Our data showed a higher incidence of thrombosis in Slovenian newborns and a higher incidence of congenital prothrombotic risk factors than in the data published so far.

Atypical presentation of thrombosis of a permanent pacemaker lead

Abstract

Pacemaker related infective endocarditis (PMIE) and pacemaker lead thrombosis (PMLT) are infrequent but potentially lethal complications of pacemaker (PM) therapy. Differences in clinical presentation, echocardiographic appearance and laboratory findings are usually helpful in making a confident diagnosis.  On the other hand, atypical clinical and echocardiographic findings may complicate their differentiation and result in a therapeutic dilemma. We present a 70-year-old man with a permanent PM hospitalized because of a 7-day history of fever and weakness. Elevated inflammatory parameters and atypical echocardiographic findings resulted in a diagnostic dilemma between PMIE and PMLT. In this paper, we discuss the pathogenesis of these entities, their clinical presentation and therapy.

Acute mesenteric ischemia caused by isolated dissection of the superior mesenteric artery and thrombotic occlusion of its major branches: treatment by systemic thrombolysis with recombinant tissue plasminogen activator (rtPA)

Abstract

Introduction. Isolated superior mesenteric artery (SMA) dissection, without associated aortic dissection, is relatively uncommon. Therefore, there are insufficient data to support a particular therapeutic option in the specific setting of isolated SMA dissection associated with thrombotic complications.
Case report. In this article we describe the diagnosis and treatment of a patient who presented to the Emergency Department with the clinical picture of an acute abdomen and signs suggestive of acute occlusion of the SMA. Diagnostic studies showed an isolated SMA dissection with acute thrombotic occlusion of its main branches. The patient was successfully treated with systemic recombinant tissue plasminogen activator (rtPA) thrombolysis. To the best of our knowledge, this is the first description of a case of isolated SMA dissection associated with thrombotic occlusion of its main branches.
Conclusion. In patients presenting with persistent abdominal pain and unspecific clinical findings, rare causes should be considered because of their life threatening complications. Systemic thrombolysis is a feasible technique for the treatment of isolated SMA dissection associated with thrombotic complications in the absence of bowel necrosis.
