ABI staging for acute bowel ischemia: Imaging findings

“Acute bowel ischemia (ABI) can be life threatening with high mortality rate. The radiologist plays a central role in the initial diagnosis and preventing progression to irreversible intestinal ischemic injury or bowel necrosis. The most single imaging findings described in the literature are either non-specific or only present in the late stages of ABI, urging the use of a constellation of features to reach a more confident diagnosis”

Preoperative portal vein embolization for major liver resection

Rassam F, et al. Functional and volumetric assessment of liver segments after portal
vein embolization: Differences in hypertrophy response. Surgery. 2019 Apr;165(4):686-695.

Full-text for Emory users.

RESULTS: A total of 90 patients underwent portal vein embolization of the right liver. After 3 weeks, there was a significant increase in both volumetric and functional share of the future remnant liver (both P < .01). The increase in functional share exceeded the increase in volumetric share (P < .01). The median functional contribution of segment 4 after portal vein embolization was 41.5% (31.7%-48.7%) of the nonembolized lobe. Preoperative chemotherapy was not a significant predictor of the increase in function or volume. Compared with benign lesions, malignant diseases were significant negative predictors of the functional response.
