The purpose of this paper is to demonstrate a variety of stent-grafting and embolization techniques and describe a new classification for endovascular treatment of isolated iliac artery aneurysms. A total of 19 patients were treated for isolated iliac aneurysms. Depending on the proximal iliac neck and the uni-/bilaterality of common iliac artery aneurysms (CIAA's) the patient may be treated by a tube (Type Ia) or a bifurcated stent-graft (Type Ib) in addition to internal iliac artery embolization. Neck anatomy is also critical in determining therapeutical options for internal iliac artery aneurysms (IIAA's). These are tube stent-grafting plus internal iliac branch embolization (Type IIa), coiling of afferent and efferent internal iliac vessels (Type IIb) and IIAA packing (Type IIc). The average length of stay for these procedures was 3.8 days. During the mean follow-up of 20.9 months, aneurysm size remained unchanged in all but 4 patients. Reinterventions were necessary in option Type Ib (3/8 pat.) and Type Ia (1/7 pat.) due to extender stent-graft migration (n = 2) or reperfusion leaks (n = 2). We conclude that Iliac artery aneurysms may be successfully and safely treated by a tailored approach using embolization or a combination of embolization and stent-grafting. Long-term CT imaging follow-up is necessary, particularly in patients treated with bifurcated stent-grafts (Type Ib).

KeywordsBreast · Abscess · Ultrasonography · Fine needle aspiration · Drainage Summary Background: The aim of our study was to analyze diagnostic results, different treatment modalities, and the outcome of patients with breast abscesses treated at our institution in a multi-modality breast team, to determine whether minimally invasive treatments are successful. Methods: 110 patients with mastitis and suspected breast abscesses at our institution between January 2000 and end of September 2007 were retrospectively analyzed. Abscesses were diagnosed using ultrasono graphy (US), and the material obtained using US-guided fine needle aspiration (FNA) was further examined. Results: 29% of the patients were treated conservatively with antibiotics only, 51% were treated with US-guided FNA or drainage placement. 11% of the patients underwent additional surgery after minimally invasive treatment (i.e. conversion rate). 9% of the patients underwent primary surgery. Early complications occurred in 7% of patients treated minimally invasive but not in patients treated with surgery alone. Late complications occurred in 5% of patients who underwent minimally invasive treatments and in 30% of patients who underwent surgery. Conclusions: US-guided FNA as a minimally invasive therapy in combination with antibiotics was found to successfully treat most breast abscesses and, in cases where a larger volume of pus was involved, the placement of an additional drainage catheter was effective.

Although melanoma frequently metastasizes to the liver, its spontaneous rupture is rare. We report herein an unusual case of a 73-year-old man with rupture of multiple hepatic metastases from scalp melanoma and resulting massive intraperitoneal bleeding, which was successfully controlled by transarterial embolization.

We report the CT imaging findings of a 33 year old patient who presented to the emergency department with increasing right lower abdominal pain and shivering. She delivered a healthy baby two weeks ago after induction in the 39th week of pregnancy due to a large fetus. Two days after delivery, sterilisation was performed. Clinically the primary differential diagnosis was appendicitis. However, computed tomography revealed thrombosis of the right ovarian vein. Consequently, management was altered appropriately with administration of antibiotics as well as a therapeutic dose of low molecular weight heparin.

We report the preoperative imaging findings of a 75 year old man with a large tumor of the lower abdomen. Computed tomography showed a large intraabdominal mass. In the differential diagnosis a gastrointestinal stromal tumor (GIST) or a metastasis of an unknown primary neoplasia were considered. Histology confirmed the diagnosis of a gastrointestinal stromal tumor (GIST).
