A ten-year, single-center experience: Concordance between breast core needle biopsy/vacuum-assisted biopsy and postoperative histopathology in B3 and B5a cases.

Purpose: To determine the concordance rate between core needle biopsy/vacuum-assisted biopsy (CNB/VAB) and postoperative histopathology in B3 (lesions of uncertain malignant potential) and B5a (in situ) lesions found on mammograms or ultrasound.

Material And Methods: 2,029 consecutive biopsies performed over 10 years for patients who underwent mammograms or ultrasounds. For CNB 14G needle and for VAB 8G/10G needles were used.

Posttraumatic Aneurysm of a Patent Umbilical Vein: Diagnosis and Specific Treatment.

A patent umbilical vein is a rare condition in healthy volunteers, but can be detected in up to 11% of patients with liver cirrhosis as a consequence of portal hypertension. We report the case of a 52-year-old woman who was admitted to our department with acute abdominal pain after blunt trauma to her forehead and abdomen. She had a history of alcohol abuse with liver cirrhosis that had been classified as Child-Pugh stage C 5 years earlier.

Thoracic aortic stent graft: comparison of contrast-enhanced MR angiography and CT angiography in the follow-up: initial results.

The objective of this study was to compare contrast-enhanced magnetic resonance angiography (CE MRA) and multislice computed tomographic angiography (MS CTA) in the follow-up of thoracic stent-graft placement. The CE MRA and MS CTA were performed following nitinol stent-graft treatment due to thoracic aneurysm ( n=4), intramural bleeding ( n=2) and type-B aortic dissection ( n=5). Corresponding evaluation of arterial-phase imaging characteristics focused on the stent-graft morphology and leakage assessment.

Perivascular inflammatory reaction to a Hemobahn stent-graft: diagnosis with 3D MR angiography.

Purpose: To present a rare perivascular inflammatory reaction to a commercially produced polytetrafluoroethylene-covered stent and demonstrate the utility of 3-dimensional (3D) magnetic resonance angiography (MRA) in the diagnosis of this phenomenon.

Case Report: Three weeks after percutaneous deployment of a Hemobahn stent-graft to treat a high-grade stenosis and aneurysm of the proximal left superficial femoral artery (SFA), a 70-year-old diabetic man developed fever, pain, and local swelling of the left thigh. Venous thrombosis was excluded by ultrasound imaging; a normal flow profile was seen in the left common and superficial femoral arteries.

Non-occlusive mesenteric ischemia: etiology, diagnosis, and interventional therapy.

Non-occlusive mesenteric ischemia (NOMI) compromises all forms of mesenteric ischemia with patent mesenteric arteries. It generally affects patients over 50 years of age suffering from myocardial infarction, congestive heart failure, aortic insufficiency, renal or hepatic disease and patients following cardiac surgery. Non-occlusive disease accounts for 20-30% of all cases of acute mesenteric ischemia with a mortality rate of the order of 50%.
