[CT- and ultrasound-guided biopsies: prospective comparison of fine-needle aspiration with true-cut biopsy in 103 patients]. / CT- und Ultraschall-gesteuerte Biopsien: Prospektiver Vergleich von Feinnadelpunktion und Stanzbiopsie bei 103 Patienten.

PURPOSE: A prospective comparison of FNAB and TCB was performed in an identical set of patients and lesions. METHODS: In 103 patients focal lesions were biopsied by US- or CT-guidance with at least one FNAB and TCB each. Complications were registered and documented. Cytological and histological specimens were evaluated independently. A final diagnosis was then attempted by consensus. RESULTS: A total of 253 punctures was performed with sufficient tissue in 72.8% (FNAB) and 85.4% (TCB) of the cases. Diagnosis was possible in 68% (FNAB) and 80.6% (TCB). After combined evaluation of both specimens the diagnostic yield increased to 91.3%. Minor complications without clinical sequelae were observed in 21 patients. CONCLUSION: A diagnostic strategy with the combined use of FNAB and TCB increases the diagnostic yield in image-guided punctures. Even though this approach needs at least two separate punctures, the complication rate does not increase.

[Inferior epigastric artery. An atypical source of bleeding in pelvic fracture]. / A. epigastrica inferior. Atypische Blutungsquelle bei Beckenfraktur.

The most common mechanism of pelvic fractures after blunt trauma is lateral compression of the pelvis. Most of these fractures are of slight severity but it is possible, that a life-threatening hemorrhage can appear. The inferior epigastric artery is an atypical bleeding site but it has to be considered in the search of the origin of the hemorrhage. Diagnostic tools are ultrasound, computed tomography and angiography. After external fixation of the pelvis and persistent haemodynamic active bleeding is the percutaneous transcatheter embolization (PTE) in our opinion the treatment of choice. The introduced case is confirm with this statement.
