Color Doppler sonography of groin complications following femoral artery catheterization.
Color Doppler sonography has proved to be an excellent technique for the evaluation of groin complications following femoral artery catheterization [1-4]. With the widespread use of fibrinolytic therapy, anticoagulants, and large-diameter vascular sheaths, a marked increase has been noted in the number of such complications [5, 6]. ⋯ In this pictorial essay we review the color Doppler sonography findings of these complications, emphasizing unusual complications such as pseudoaneurysms coincident with arteriovenous fistulas, multilobulated pseudoaneurysms, ruptured pseudoaneurysms, and patent needle tracts. We also discuss the diagnostic pitfalls and mimics of groin injuries, including lymphadenopathy, varicosities, true aneurysms, and atypical but normal branch vessels.

Anatomic distribution of venous thrombosis in patients with antiphospholipid antibody: imaging findings.
Antiphospholipid antibodies are immunoglobulins that cross-react with phospholipid within cell membranes. These antibodies have been associated with a hypercoagulable state manifested by early stroke, frequent arterial and venous thromboses, recurrent fetal loss, thrombocytopenia, and livedo reticularis (antiphospholipid syndrome). The purpose of this study was to determine the anatomic distribution of venous thrombosis in patients with antiphospholipid antibodies as seen on imaging examinations. ⋯ Deep veins of the leg were the most common site of venous thrombosis. The thoracic and abdominal venous system and the dural sinuses--unusual sites of thrombosis in the general population--are other common sites. Antiphospholipid antibodies should be suspected when thromboses are found in these locations in the absence of other known risk factors, or when found in combination with arterial thromboses or CNS ischemic disease in young or middle-aged patients.

Meta Analysis Comparative StudyTriage of patients to angiography for detection of aortic rupture after blunt chest trauma: cost-effectiveness analysis of using CT.
The purpose of this study was to evaluate the cost-effectiveness of dynamic chest CT, compared with plain chest radiography and immediate angiography, in deciding when angiography should be performed in hemodynamically stable patients with suspected aortic rupture after blunt chest trauma. The use of CT was evaluated in relation to the prior probability of aortic rupture. ⋯ Selecting hemodynamically stable patients after blunt chest trauma with suspected aortic rupture for angiography on the basis of CT findings is more effective than doing so based on the findings on chest radiography and is cost-effective compared with other accepted health care programs. Immediate angiography has a high incremental cost-effectiveness ratio compared with triage by CT and is warranted only in patients not undergoing CT for the evaluation of other injuries who have a prior probability of aortic rupture of 5% or more.

CT in patients with blunt abdominal trauma: clinical significance of intraperitoneal fluid detected on a scan with otherwise normal findings.
The purpose of this study was to determine the clinical significance of intraperitoneal fluid seen on CT scans with otherwise normal findings in patients with blunt abdominal trauma. ⋯ Patients with blunt abdominal trauma who have small amounts of intraperitoneal fluid as the sole abnormality shown by CT may generally be treated conservatively. However, patients with even a small quantity of mesenteric fluid may benefit from peritoneal lavage to help exclude bowel or mesenteric injury. Intermediate and large amounts of fluid are less common as the sole CT abnormality but have a higher likelihood of being associated with bowel or mesenteric injury.
