Purpose: To identify common findings visualized on CT following damage control laparotomy, including post-surgical changes and additional injuries, and to determine change in frequency of post-laparotomy CT at our institution over time.

Methods: Single institution, IRB-Exempt, retrospective review of the University of Kentucky trauma registry from 1/2006 to 2/2019 for all trauma patients undergoing exploratory laparotomy initially and subsequently undergoing CT of the abdomen and pelvis within 24 hours. Operative findings from surgical operation notes and findings reported on post-laparotomy CT were recorded, including vascular and solid organ injuries, operative changes, free intraperitoneal fluid/air, and retroperitoneal findings. Next steps in …


The "Lightning Bolt" Sign On Computed Tomography During Percutaneous Renal Mass Cryoablation, Qian Yu, Driss Raissi Aug 2018

The "Lightning Bolt" Sign On Computed Tomography During Percutaneous Renal Mass Cryoablation, Qian Yu, Driss Raissi

Radiology Faculty Publications

Ice‑ball fracture is a rare and often overlooked entity that may lead to intraprocedural hemorrhage after percutaneous cryoablation of renal masses. There is scant literature on ice‑ball fractures associated with percutaneous renal cryoablation. Immediate recognition of the lightning bolt sign during intraprocedural computed tomography can help identify patients who may have developed this complication.

Background

The objective of this study is to evaluate the safety and quality of computed tomographic angiography of the thoracic aorta (CTA-TA) exams performed using intraosseous needle intravenous access (ION-IVA) for contrast media injection (CMI).

Methods

All CTA-TA exams at the study institution performed between 1/1/2013 and 8/14/2015 were reviewed retrospectively to identify those exams which had been performed using ION-IVA (ION-exams). ION-exams were then analyzed to determine aortic attenuation and contrast-to-noise ratio (CNR). Linear regression was used to determine how injection rate and other variables affected image quality for ION-exams. Patient electronic medical records were reviewed to identify any …
