This case describes the diagnostic testing and management of an acute thrombosis of the brachial artery in a female neonate. On day seven of life, clinical signs of acutely decreased peripheral perfusion indicated an occlusion of the brachial artery, which was confirmed by high-resolution Doppler ultrasound. Imaging also showed early stages of coll...

Background: Low Molecular Weight Heparin (LMWH) has widely replaced its parent and oldest anticoagulant compound "Heparin" due to its numerous advantages. However, LMWH are not devoid of adverse effects which may be serious. Since the therapeutic dose of LMWH "Enoxaparin" is determined by a weight-based regimen, the incidence of adverse events may...
Heparins inhibit the thrombin forming capacity of plasma, i. e., the endogenous thrombin potential (ETP), by their anti-thrombin (aIIa) activity, the anti-factor Xa (aXa) activity is of minimal importance. This holds for both unfractionated heparin (UFH) and low molecular weight heparin (LMWH) at aXa/aIIa ratios < 25. Clinical experience and epidem...
Venous thromboembolism (VTE) is a major cause of morbidity and mortality in patients with cancer. For over a decade, the gold standard of treatment and secondary prevention of cancer-associated thrombosis (CAT) has been represented by low-molecular-weight heparins (LMWHs), which are currently recommended as the first-line treatment for CAT. Among t...
Introduction: Patients with gastrointestinal cancer are at high risk of developing thrombosis and postoperative infection. Antico-agulation therapy for such patients is provided by low molecular weight heparin (LMWH) and elastic stockings. The latter, however, is linked to immunoregulatory activities and immunosuppression in vivo and in vitro.

Occlusion of the venous or arterial vessels in childhood is rather rare but dangerous complication. Occurrence of neonatal thrombosis is 0.5 per 10 000 of live newborns. Promoting factors include congenital defects of coagulation, maternal diabetes, neonatal sepsis, necrotic enterocolitis, asphyxia, and metabolic diseases. More than 90 % cases of neonatal thrombosis are associated with catheterization (umbilical arterial or venous, other central venous lines). Acute arterial thrombosis caused by a peripheral venous catheter is very rare complication, but it can result in severe consequences. The article contains a clinical case of right brachial artery thrombosis in a premature boy with extremely low body weight complicated by development of dry gangrene and amputation of the limb. Complex risk factors promoting development of neonatal arterial thrombosis were found: preterm birth, neonatal sepsis, possible incorrect insertion of a peripheral venous catheter. Associative factors were congenital developmental defects of the intestine (high rectal atresia) and heart (bicuspid aortal valve, open oval foramen), and maternal factors. The authors emphasize their attention on the necessity to continuous education of the medical staff concerning the technique of catheter insertion and care of them, absolute implementation of safety policy concerning nosocomial infection, adequate provision of ultrasound examination devices with high rarefaction sensors, involvement of a multi-disciplinary team of specialists to manage complicated clinical cases.
