pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. as a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. here we report a case...

The aim is to describe the technique of preoperative CT-guided hookwire localization of small, but suspicious, cervical lymph nodes. We present 3 patients who underwent the procedure for nonpalpable cervical nodes detected on PET/CT prior to complete surgical resection of the nodes. The details of the radiological procedure, surgical outcomes, and pathologic results are described. The mean inte...

BACKGROUND Intraoperative localization of image or endoscopy-detected lesions occasionally pose surgical challenges due to the small lesion size and/or difficult anatomic exposure. Identification of such lesions can be facilitated using a hand-held gamma probe with utilization of Tc-99m macroaggregate albumen (MAA) localization technique. The radiopharmaceutical injection can be performed using...

BACKGROUND Video-assisted thoracic surgery (VATS) is currently performed to diagnose and treat solitary pulmonary nodules (SPN). However, the intra-operative identification of deep nodules can be challenging with VATS as the lung is difficult to palpate. The aim of the study was to report the utility and the results of pre-operative computed tomography (CT)-guided hook wire localization of SPN....

Rapid enhancement and early washout are generally observed in breast carcinomas, but there are exceptions to this pattern. Certain carcinomas, particularly lobular cancer and carcinoma in situ, may enhance slowly or not at all. On the other hand, some enhancement can be seen in benign lesions such as fibroadenomas. Because of its high sensitivity, MRI reveals small lesions that may not be visib...

OBJECTIVES Video-assisted thoracic surgery (VATS) provides a minimally invasive means to resect pulmonary nodules (PN). Deep localization of PN may jeopardize VATS lung resection. The aim of this study was to establish the utility of preoperative computed tomography (CT)-guided hookwire localization of PN. METHODS Between January 1993 and September 2001, we performed 151 VATS resections for P...
