Stereotactic breast biopsy: a six-year surgical experience.

A retrospective review was done of all stereotactic breast biopsies performed at the Central Baptist Hospital Breast Center from February 1994 through December 1999. A total of 1,080 biopsies were performed in 1,026 patients, all by surgeons working independently. Masses were biopsied in 54% and calcifications in 40%. Eighteen percent of biopsies were malignant. The most common benign diagnosis was fibrocystic disease (72%), followed by fibroadenoma (19%), lymph node (2%), and papilloma (2%). The most common malignant diagnosis was invasive ductal carcinoma (40%) followed by ductal carcinoma in situ (32%) and mixed invasive and in situ ductal carcinoma (19%). A prebiopsy BI-RADS mammographic Category III was associated with a 2% incidence of malignancy; Category IV--17%; Category V--90%. Atypical ductal hyperplasia on stereotactic biopsy was upgraded to a malignant diagnosis after reexcision in 19% of the cases. The false-negative rate was 0.4% (sensitivity 99%) and the complication rate was 3%, mostly related to bleeding. Stereotactic biopsy is a safe and accurate technique for the minimally-invasive diagnosis of abnormal mammograms.

Breast conservation versus mastectomy: patient preferences in a community practice in Kentucky.

Recent studies have indicated a relatively low rate of breast-sparing surgery for carcinoma in the Southeastern United States. From 1987 through 1991, 289 patients from Eastern and Central Kentucky with breast carcinoma were treated by the authors. Despite being fully informed of treatment options of breast cancer, 82% of patients with stage II disease or less and no medical contraindications to breast conservation preferred mastectomy. Overall, 10% of patients underwent breast-sparing surgery, although this figure had risen to 20% by 1991. The most frequent reasons for preference of mastectomy were fear and inconvenience of radiotherapy and a perception that survival would be diminished if mastectomy was not done.

Axillary artery aneurysm as an occult source of emboli to the upper extremity.

Reported here is a case of axillary artery aneurysm secondary to crutch trauma as a source of emboli to the upper extremity. This patient along with several reported in the literature was initially diagnosed and treated for brachial artery embolism. It is believed that awareness of this entity as a cause of forearm and hand ischemia is important in planning the appropriate surgical therapy.

The problem of the cystic duct remnant.

Symptoms persisting after cholecystectomy for gallbladder disease are often attributed to a long residual cystic duct. Of 30 patients who underwent excision of their cystic duct remnant, 15 were found to have common duct stones which accounted for their symptoms, while an additional four patients had had previous episodes of jaundice which suggested passage of a common duct stone. Those patients with common duct disease in addition to the cystic duct remnant were completely relieved of their symptoms by operation while only eight of the patients without common duct stones obtained relief. A cystic duct remnant infrequently causes symptoms in the absence of pathologic conditions in the common duct.
