Comparative StudyDeep venous thrombosis and pulmonary embolism in trauma patients: an overstatement of the problem?
Deep venous thrombosis (DVT) and pulmonary embolism (PE) affect high-risk trauma patients (HRTP). Accurate incidence and clinical importance of DVT and PE in HRPT may be overstated. We performed a ten-year retrospective analysis of HRTP of the Pennsylvania Trauma Outcome Study. ⋯ Though increased during the past decade, the overall incidence of DVT in HRTP remains below 3 per cent. Only the combination of multiple injuries or an ISS >30 result in DVT incidence of > or =5 per cent. We believe that current guidelines for screening for DVT may need to be reevaluated.

Case ReportsA Jehovah's Witness with complex abdominal trauma and coagulopathy: use of factor VII and a review of the literature.
Management of acute bleeding in patients who are Jehovah's Witnesses remains a challenge. Clearly, the most important concept is meticulous and early hemostasis to minimize ongoing blood loss. This is generally followed by supportive measures. ⋯ In this case, we believe the product was life-saving. Most importantly, there were no religious objections to its use. In appropriate patients, when surgical bleeding is controlled and there is still evidence of dilutional coagulopathy, factor VIIa may have a real role in patients, particularly those who are Jehovah's Witnesses.

Retroperitoneal bleeding is one of the most serious, potentially lethal complications of anticoagulation therapy. Although well documented in fully heparinized and coumadinized patients, there are only few reports of life-threatening hemorrhages in low-molecular-weight heparin (LMWH)-treated patients. We present a case of almost fatal spontaneous retroperitoneal bleeding in a 71-year-old woman with pneumonia and acute coronary syndrome. ⋯ It appears that those at highest risk receive doses approaching 1 mg/kg subcutaneously every 12 hours, have renal impairment, are of advanced age, and receive concomitant medications that can affect hemostasis. On average, a retroperitoneal hematoma occurs within 5 days of therapy with enoxaparin. In high-risk patients, enoxaparin activity (anti-factor Xa) should be carefully monitored.

Assessment of nonoperative management of blunt spleen and liver trauma.
An 8-year analysis of nonoperative management (NOM) of spleen and liver trauma was done in a level 1 trauma center. Spleen and liver trauma was diagnosed in 279 patients: 93 children (<18), 137 younger adults (18-54), and 49 older adults (> or = 55). Nineteen patients who failed resuscitations died within 0-60 minutes of arrival and were excluded from treatment analysis. ⋯ Female patients had higher mean injury severity score, age, and mortality compared to cohorts. NOM should be attempted in hemodynamically stable patients. Age over 55, higher grades of injury, and large hemoperitoneum were not predictors of failure of NOM.

Case ReportsManagement of subclavian and axillary artery injuries: spanning the range of current therapy.
Injuries of the subclavian and proximal axillary arteries are potentially devastating but account for a minority of vascular injuries presenting to trauma centers in the United States. We have reviewed our recent experience with management of subclavian and axillary artery injuries in a state-designated level 1 academic trauma center and report four cases that illustrate the typical arterial injury patterns and the entire therapeutic armamentarium in its current iteration. Subclavian and proximal axillary artery injuries present as interesting surgical problems. ⋯ Consideration should always be given to the least invasive treatment options in stable patients. Awareness of multiple therapeutic modalities and indications for each should be an integral part of every surgeon's armamentarium. As with all vascular intervention, eventual failure is the rule rather than the exception; therefore, plans for longitudinal surveillance should be made independent of the technique used to treat the injury.
