A 20year patient was first encountered by the Obstetric team at twenty-two weeks pregnant when she presented with signs and symptoms of a deep vein thrombosis; she was diagnosed with extensive bilateral external iliac DVT and was managed by a multidisciplinary team for the treatment of thrombosis and detoxification by a Methadone programme. A variety of social factors had led her to heroin addiction: her parent was a drug addict. She had been raised by numerous foster carers until she then found her mother who introduced her to drug addiction. Her partner was violent and forced her to be a commercial sex worker and she lived in a community where substance misuse was rampant. During this pregnancy, the Obstetric care and MDT support helped this patient to successfully detoxification from her heroin addiction and the use of other illicit substances. She had a normal vaginal delivery of a healthy infant, which was immediately taken into care. Post-natal follow up ensured abstinence of illicit substances and an opportunity for this patient to change her lifestyle and social setup. This case report is a success story of a patient who initially sought medical help in desperate and life-threatening circumstances. It highlights the importance of a multidisciplinary approach in the successful management of a high risk pregnancy and a detoxification programme. This case required a holistic and patient-centred approach to the antenatal care, along with willingness to change and determination from the patient herself.
