A national survey of thromboprophylaxis in traumatic brain injury in the United Kingdom.

INTRODUCTION: Patients with traumatic brain injury (TBI) are at increased risk of venous thromboembolic events (VTE). In this survey, we aimed to assess current practice in the United Kingdom and identify areas of variation for further investigation. METHODS: We distributed a case-based survey to neurosurgical consultants and trainees via e-mail. The survey included four index TBI cases commonly seen: a surgically treated acute extradural haematoma, bilateral frontal contusions treated conservatively, diffuse axonal injury requiring critical care and a conservatively managed small acute subdural haematoma. Each case vignette included questions looking at a range of areas regarding thromboprophylaxis. RESULTS: Sixty-two responses were collected among UK neurosurgeons with a good geographic distribution. In each case, over 90% of respondents would initiate mechanical prophylaxis (MTP) at admission. There was greater variation on the decision to commence pharmacological prophylaxis (PTP). Consultants showed a higher willing to commence PTP across all cases (84%) compared to trainees (77.4%). Low molecular weight heparin (LMWH) was the favoured PTP agent in over 90% of respondents. There was significant variability in the timing of initiation of PTP within and between cases. The median times to commence PTP across all four cases ranged from 1 to 7 days. CONCLUSION: This survey highlighted broad consensus on the use of MTP and choice of PTP agent, when used. However, the survey also demonstrated wide intra-case variation on whether to start PTP and particularly the timing of initiation. This discordance in practice shines light on the lack of evidence guiding thromboprophyalxis in TBI and adds weight to the need for prospective randomised trials to guide clinical management.

Pleural epithelioid hemangioendothelioma: literature summary and novel case report.

Epithelioid hemangioendothelioma (EHE) is a rare malignant cancer of vascular origin that can affect multiple and varied tissue sites. A subtype of EHE, pulmonary epithelioid hemangioendothelioma (PHE), is more unusual with only 200 reported cases. Of these, only 27 have been classified as pleural in origin. Based on available literature, the average age of presentation of pleural PHE is 45.7 years with a male preponderance of 2.375. A summary of all published case reports reveals significant heterogeneity both in presentation and management. Here we add to this knowledge-base with a report of an unusual case of pleural PHE in a 36-year-old female who presented with a 6-week history of chest pain and breathlessness. Significant challenges in the diagnosis and management of patients with pleural PHE exist, including a wide initial differential diagnosis and difficulties in obtaining tissue specimens, coupled with relatively limited treatment options. Early referral to a cardiothoracic center for video-assisted thoracoscopic biopsy is crucial in facilitating a diagnosis and allowing adequate pleural drainage for symptomatic relief.
