Excessive blood loss. Infection. Pre-eclampsia.

. Investigations Compression du plex ultrasound is the primary diagnostic test for DVT. If ultrasound is negative and there is a low level of clinical suspicion, anticoagulant treatment can be discontinued and no further investigation is required. If ultrasound is negative but a high level of clinical suspicion exists, the woman should continue anticoagulation until the ultrasound is repeated in one week or an alternative diagnostic test employed.

If the repeat testing is negative, then anticoagulant treatment can be discontinued. If there is any suspicion of iliac vein thrombosis (suggested by symptoms of back pain and swelling of the entire limb), then contrast or magnetic resonance venography should be used to confirm the diagnosis. A simple initial investigation in an ambulatory woman with suspected PTE is to perform oxygen saturation measurements by a pulse oximeter at rest and after exertion (such as walking up a flight of stairs).

Resting hypoxia or a fall of more than 3% after exertion requires formal arterial blood gases. D-dimers are of limited value in the puerperium as they may be elevated as part of a healthy pregnancy. They can be performed for their negative predictive value (94%), as in a woman with a normal result the risk that a thrombotic event has occurred is low, and further investigation may be avoided unless the clinical suspicion is extremely high [9].

Where there is clinical suspicion of acute PTE, a chest X-ray should be performed. Compression duplex Doppler should be performed if this is normal. If both tests are negative but there is persistent clinical suspicion of acute PTE, a ventilation perfusion (V/Q) lung scan or a computed tomography pulmonary angiogram (CTPA) should be performed.

Repeat testing should be carried out where V/Q scan or CTPA and duplex Doppler are normal but the clinical suspicion of PTE is high. Anticoagulant treatment should be continued until PTE is definitely excluded. A chest X-ray can identify other pulmonary disease such as pneumonia, pneumothorax or lobar collapse.

However, the chest X-ray is normal in over 50% of women with subsequently proven PTE. Abnormal features caused by PTE include atelectasis, pleural effusion, focal opacities, or pulmonary oedema. The choice of technique for definitive diagnosis (V/Q scan or CTPA) will depend on local availability and should be only made after a discussion with the radiologist.

. Clinical features        Leg pain and swelling (usually unilateral). Lower abdominal pain. Low-grade pyrexia.

Dyspnoea. Chest pain. Haemoptysis.

Maternal collapse (massive PTE).. Any postna Visual Studio .NET PDF417 tal woman with signs and symptoms suggestive of VTE should commence treatment with low molecular weight heparin (LMWH) without delay until the diagnosis is excluded by objective testing [8]. The only exception to this would be if there was a reason why treatment is strongly contra-indicated, such as active bleeding or a high risk if further bleeding were to occur.

In this situation, intravenous unfractionated heparin (this has a shorter half-life and can be reversed with protamine sulphate) should still be considered with the risks of treatment weighed against non-treatment. Before anticoagulant therapy is commenced, blood should be taken for a full blood count, coagulation screen, urea and electrolytes and liver function tests. A thrombophilia screen is not routinely recommended, as the immediate management of acute VTE is not influenced by the results.

As pregnancy can give false positive results, if undertaken thrombophilia screens should be interpreted by a haematologist. In long-term management a thrombophilia screen will be required, but this can be arranged after the acute event. Investigations should be arranged with minimum delay and local protocols should reflect this and be followed.

Multidisciplinary input from obstetricians, physicians, haematologists and radiologists is recommended to optimize the management of suspected and particularly confirmed thrombosis [9]..
