The outcome of the conference was the generation of 33 recommendations for the diagnosis and management of HHT, with at least 80% agreement amongst the expert panel for 30 of the 33 recommendations.

Selective intervention to treat type II endoleak that persists for 6 months and is associated with aneurysm enlargement seems to be both safe and cost-effective. Longer follow-up will determine whether this conservative approach to management of type II endoleak is the standard of care.

The computed tomographic (CT) findings in 52 patients with histologically proved esophageal carcinoma were reviewed. In 30 of these patients, the CT findings were correlated with findings at surgery or autopsy. CT was found to be highly accurate in predicting tumor size and assessing invasion of the tracheobronchial tree and spread to the liver, adrenals, and celiac and left gastric nodes. By quantifying the contact between the tumor and aorta, it was found that the CT appearance correctly predicted the presence or absence of aortic invasion in 24 of 25 cases (five cases were indeterminate). CT was insensitive in detecting metastatic spread to local periesophageal nodes; in these cases the tumor tended to involve the nodes without enlarging them. CT is an accurate method for assessing the spread of esophageal carcinoma. Its use can prevent unnecessary surgery in patients with inoperable tumors.

The sensitivities of contrast medium-enhanced computed tomography (CT), delayed CT (DCT), CT during arterial portography (CTAP), and magnetic resonance (MR) imaging for detecting focal liver lesions were prospectively evaluated in eight patients who subsequently underwent hepatic lobectomy or transplantation. Pathologic evaluation of the resected liver specimens demonstrated 37 lesions. The sensitivities were 81% (30 of 37 lesions) for CTAP, 57% (21 of 37 lesions) for MR imaging, 52% (12 of 23 lesions) for DCT, and 38% (14 of 37 lesions) for contrast-enhanced CT. The difference between the sensitivity of CTAP and the sensitivities of the other imaging tests was statistically significant (P less than .004). Of the lesions smaller than 1 cm in diameter, CTAP depicted 61% (11 of 18 lesions), MR imaging 17% (three of 18 lesions), CT 0% (zero of 18 lesions), and DCT 0% (zero of nine lesions). It is concluded that for preoperative detection of focal hepatic masses, CTAP is the most accurate technique available to most radiologists. Patients with primary or secondary hepatic neoplasms who are being considered for hepatic resection should undergo CTAP as part of their preoperative examination.
