Initial clinical experience with biopolymer-coated detachable coils (HydroCoil) in peripheral embolization procedures.

Purpose: To evaluate the technical and clinical success of HydroCoils in patients who underwent peripheral embolization procedures.

Materials And Methods: Between July 2006 and June 2007, 12 peripheral embolization procedures with HydroCoils in 11 patients (six male patients and five female patients; age range, 4-74 years; mean age, 46 y) were available for this retrospective review. The indications for embolization were hemorrhage (n = 4), aneurysm (n = 1), recurrent pulmonary arteriovenous malformation (n = 1), and protection before radioembolization and chemoembolization (n = 5).

Imaging diagnosis of acute pulmonary embolism.

Pulmonary embolism represents a major public healthcare problem and it also imposes frequent clinical diagnostic issues. Despite the availability of the D-dimer tests, imaging remains the mainstay for its diagnosis. Computed tomography pulmonary angiography (CTPA) is now the most widely used diagnostic test and its utility has been well validated in a large number of trials.
