intrapulmonary density can usually be accomplished by obtaining posteroanterior ( PA) and lateral chest roentgenograms. However, when one is confronted with an abnormality within the lung, only the PA chest film may be available for appraisal. In the presence of multiple infiltrates in both lungs, it may be difficult to locate precisely the segmental distribution even after viewing the lateral ...

BACKGROUND AND PURPOSE Childhood intracerebral hemorrhage is mainly attributable to underlying brain arteriovenous malformations (bAVMs). Multimodal treatment options for bAVMs include microsurgery and embolization, allowing an immediate cure, and radiosurgery, entailing longer obliteration times. Follow-up data on pediatric ruptured bAVMs are scarce, making it difficult to assess the risk of s...

Persistent urachal anomalies are rare congenital lesions of the urinary tract. They result from failed obliteration urachus and classified according to persistent segment urachus.

BACKGROUND Epidemiological studies show that about 11.6% to 33.0% of all boys and about 3.6% to 19.3% of all girls suffer dental trauma of varying severity before the age of 12 years. Moderate injuries to the periodontium such as concussion and subluxation are usually associated with relatively minor symptoms and hence may go unnoticed by the patient or the dentist, if consulted. Patients with ...

OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...

The appendix being the common site for inflammation, an idea came to the mind that if the lumen is obliterated whether we can prevent inflammation. With this idea at the back of the mind a study was made in appendices which showed obliteration of the lumen or a very little lumen. 228 biopsy specimens sent to the pathology department of our college during the past 1 and 1/2 years were used for t...

BACKGROUND AND PURPOSE Stent-assisted coiling and balloon-assisted coiling are 2 well-established techniques for treatment of wide-neck intracranial aneurysms. A direct comparative analysis of angiographic outcomes with the 2 techniques has not been available. We compare the angiographic outcomes of wide-neck aneurysms treated with stent-assisted coiling versus balloon-assisted coiling. MATER...

BACKGROUND AND PURPOSE Endovascular treatments for aneurysms are being used more frequently in patients in the absence of a large body of information on their histopathological effects. This study determined the efficacy and histopathological effects of treatment of experimental aneurysms with Guglielmi detachable coils (GDC) or cellulose acetate polymer (CAP). METHODS Fourteen dogs had 13 te...

A 64-year-old woman treated for anemia and ascites exhibited hepatic encephalopathy. Abdominal ultrasonography and computed tomography (CT) showed communication between the portal vein and the middle hepatic vein, indicating an intrahepatic portosystemic venous shunt (PSS). Since hepatic encephalopathy of the patient was resistant to medical treatment, interventional radiology was performed for...
