Abstract:

The pathological activated partial thromboplastin time test is a data that we can find in all clinical laboratories routinely. The hemato-coagulative clinical case here reported aims to point out how the laboratory can provide a correct diagnosis by methodological rational setting and, consequently, carry out an appropriate therapy, or reassure the patient that the pathological data will not cause bleeding, even in case of surgery.

Evaluation of Antiphospholipid Antibodies and Activated Partial Thromboplastin Time in Women with Adverse Outcome of Pregnancy

Adverse outcome of pregnancy is a potentially dangerous complication of conception and affects 15-20% of pregnancies. According to recent studies increased level of blood antiphospholipids antibodies, if accompanied by predisposing factors, can be an adverse event in human pregnancy. The aim of the present study was to compare the maternal serum levels of anticardiolipin and antiphosphatidyl se...

The partial thromboplastin (cephalin) time test.

Nine partial thromboplastin (cephalin) reagents have been compared in a parallel investigation of groups of patients on ;long-term' anticoagulants, a group with moderate haemophilia, and patients on heparin infusion. Results with the seven commercial reagents and a human cephalin extract have been correlated with those of a specially prepared and standardized reference preparation of human brai...

Sequential thrombosis and bleeding in a woman with a prolonged activated partial thromboplastin time

Simultaneous or sequential haemorrhage and thrombosis in the presence of a prolonged activated partial thromboplastin time (aPTT) is a rare occurrence: we describe the case a 37 year old lady who developed post-delivery deep vein thrombosis treated with low molecular heparin and warfarin followed a week later by extensive bruising over legs and forearms, a significant drop in haemoglobin and a ...

A Patient with a Prolonged Activated Partial Thromboplastin Time and a Deep Intracerebral Haemorrhage

We report on a 57-year-old woman with a pontine haemorrhage and an extremely prolonged activated partial thromboplastin time (aPTT) of more than 240 s, suggestive of a coagulation disorder. Given the location of the haemorrhage, which is associated with a high mortality rate, recombinant factor VIIa was administered, although not all necessary laboratory analyses could be performed at that time...

Prolonged Partial Thromboplastin Time Without Bleeding History; Fletcher Factor Deficiency.

A 67-year-old patient was admitted to the hospital to perform an esophagogastrectomy because a lesion at the lower esophagus was strongly suspicious for cancer. Her medical history and her family history were negative for bleeding tendency or thrombosis. Her activated partial thromboplastin time (aPTT) was prolonged (44 s) whereas her prothrombin time (PT) was normal (11 s) presurgery. Mixing o...
