Late aortic rupture following successful endovascular repair of abdominal aortic aneurysm still does occur. It represents the ultimate failure of endovascular aortic repair of abdominal aortic aneurysm (EVAR) and subjects patients to equivalent risk of death as de novo rupture. Unfortunately, it is difficult to identify patients at risk for post-EVAR rupture as many present with aortic rupture in the absence of any endograft-related complications. Continued surveillance and timely intervention are of paramount importance to assure rupture-free survival, the ultimate goal of any aneurysm treatment modality. The vascular surgeon needs to be prepared to provide the optimal therapy, whether open or endovascular, for this challenging cohort of patients.

1. Audiometiric examination for 14 cases of retinal pigmentary degeneration revealed a case of conductive deafness, and 4 cases of perceptive hearing disturbances. 2. There were no complaints of subjective hearing disturbances among the cases of perceptive hearing impairments. 3. All the cases of perceptive hearing loss were thought to be due to cochlear lesion according to tone decay tests. 4. There were no cases accompanied by systemic or neuropsychiatric disorders among the 14 cases of retinal pegmentary degeneration. 5. It has been emphasized that pigmentery degeneration of the retina is frequently associated with perceptive hearing disturbances. Genetical and etiological discussions were tried for this association.

PURPOSE: To prove whether the arterioportal shunt, especially transvasal shunt is one of the cause of the hypovascular hepatocellular carcinoma. MATERIALS AND METHODS: We evaluated the early phase images of table incremental dynamic CT and hepatic angiography in 20 cases of hepatoceltular carcinomas with transvasal arterioportal shunt. RESULTS: In hepatic arteriography, 18 cases were hypovascular and the remained 2 cases showed hypervascular tumor staining than surrounding normal hepatic parenchyme. In the early phase dynamic CT, 18 cases were hypodense(including 4 cases of focal hyperdensity in hypodense background), one was isodense and remaining one was hyperdense. CONCLUSION: Arterioportal shunt, especially transvasal shunt may make originally hypervasular hepato-cellular carcinoma to hypovascular lesion in the early phase dynamic CT or hepatic arteriography. In attempt to differentiate hepatic masses by tumor vascularity in recently widely used table incremental dynamic CT, the vascular patterns of the mass should be considered by close evaluation of vascular pattern of the liver, such as morphology of perfusion abnormality and arterioportal shunt, etc.

Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

PURPOSE: To document the radiologic characteristic findings of atypical ductal epithelial hyperplasia, we analyzed film mammographic, ultrasonographic, and MRI findings of our cases. MATERIALS AND METHODS: We analyzed 23 cases of surgically proven ADH, excluding carcinoma in ipsilateral breast. Presence and pattern of neodensity, microcalcification, and architectural distortion were reviewed on mammography. Echo pattern and ductal parenchymal morphology were analyzed on ultrasonography, and enhancement speed and pattern analysis were performed on MRI. RESULTS: On film mammography, ADH showed tendency of neodensity(10 of 23 cases), m icrocalcification(11 of 23 cases), with less parenchymal distortion of surrounding structures(7 of 23 cases). On ultrasonography, ADH was demonstrated as inhomogenous to intermediate echoic nodule(16 of 20 cases) with ragged border(19 of 20 cases), however, its boundary was thin or nearly absent(16 of 20 cases), and showed smooth ductal echography(11 of 20 cases). Gd-DTPA contrast dynamic MR study showed relatively slow and less enhancement in 4 out of 5 cases, with progressive inclination of the speed curve of enhancement in later period of dynamic study. CONCLUSION: Multimodality image approach is needed for better evaluation of ADH, however, excisional biopsy is recommended for confirmative diagnosis and proper treatement.

Recurrent posterior shoulder instability is a debilitating condition that is relatively uncommon, but its diagnosis in young adults is increasing in frequency. Several predisposing factors for this condition have been identified, such as the presence of an abnormal joint surface orientation, an osteochondral fracture of the humeral head or glenoid cavity, and a postero-inferior capsuloligamentary deficit, but their relative importance remains poorly understood. Whilst, conservative treatment is effective in cases of hyperlaxity or in the absence of bone abnormality, failure of conservative treatment means that open or arthroscopic surgery is required. In general, soft-tissue reconstructions are carried out in cases of capsulolabral lesions in which bone anatomy is normal, whereas bone grafts have been required in cases where posterior bony Bankart lesions, glenoid defects, or posterior glenoid dysplasia are present. However, a consensus on the exact management of posterior shoulder instability is yet to be reached, and published studies are few with weak evidence. In our study, we report the reconstruction of the glenoid using iliac bone graft in a patient suffering recurrent posterior shoulder instability with severe glenoid bone defect.
