Near-infrared fluorescence angiography for intra-operative assessment of pedicled omentoplasty for filling of a pelvic cavity: a pilot study

ConclusionsFA of a pedicled omentoplasty allows a real-time assessment of omental perfusion and leads to change in management in 80% of the cases in this pilot study. These findings support the conduct of larger studies to determine the impact on patient outcome in this setting.

Objectives The aim of this study was to evaluate the feasibility of a computed tomography (CT) protocol enabling the visualization of the prostatic artery (PA) before prostatic artery embolization (PAE) in benign prostatic hyperplasia, which provides quantitative perfusion information of the prostate gland. Materials and Methods In this institutional review board–approved study, 22 consecutive patients (mean age, 67 ± 7 years) who were planned to undergo PAE underwent a dynamic CT scan of the pelvis (scan range, 22.4 cm; cycle time, 1.5 seconds; scan time, 44 seconds; 25 scan cycles; 70 kVp; 100 mAs) afte...

Publication date: Available online 7 September 2019Source: Journal of Cardiology CasesAuthor(s): Shozo Sueda, Hiroaki KohnoAbstractA 61-year-old man was admitted to our hospital due to chest pain on both rest and effort. After the computed tomography coronary angiography, coronary stenosis was recognized at segment 3. Because inferior ischemia on stress myocardial perfusion scintigraphy with 201 thallium chloride induced by adenosine was found, we planned to perform the coronary intervention. After control coronary angiography, no significant stenosis was found in the right coronary artery. Intracoronary acetylcholine test...

Objectives: Endovascular therapy (EVT) improves outcomes for appropriately selected acute ischemic stroke patients. Guidelines suggest rapid acquisition of noninvasive vascular imaging to screen suspected ischemic stroke patients for large vessel occlusion (LVO) and candidacy for EVT. We sought to quantify the yield of an LVO stroke screening process in an undifferentiated emergency department (ED) suspected stroke population as well as identify predictors of successful EVT. Methods: We identified a cohort of consecutive ED patients who received CT angiography and brain perfusion (CTA/P) imaging to determine candidacy for EVT during 2016.

In 2009, the Society of Interventional Radiology (SIR) published training guidelines for intraarterial catheter-directed treatment of acute ischemic stroke (1). At that time, catheter-directed thrombolysis was the dominant endovascular therapy and the only such therapy studied in randomized trials (2,3). Only first-generation mechanical thrombectomy devices were available. Computed tomographic (CT) angiography, magnetic resonance (MR) angiography, and perfusion imaging were not routinely used for assessment of large-vessel occlusion and/or parenchymal infarction and ischemia.

Conclusion: IcGA is safe to use as demonstrated by the very low rate of complications in this case series. It is also safe to rely on to guide re-resection and recreation of an anastomosis intraoperatively by demonstration of blood flow. This may help offset the loss of tactile feedback and assessment of tension in the robotic platform. PMID: 31467710 [PubMed]

AbstractPurposeTo evaluate the feasibility of 2D-perfusion angiography (2D-PA) for detecting leakage of the double-balloon catheter used for chemosaturation percutaneous hepatic perfusion (CS-PHP).Materials and MethodsOverall, 112 CS-PHP (09/2015-09/2018) in 52 patients were retrospectively screened for leakage alongside the double-balloon catheter on standard venograms. Finally, 18 procedures with visually detected leakage were included. Fifteen consecutive procedures without leakage served as control. To evaluate 2D-PA for leakage detection, the acquired digital subtraction venograms were post-processed. For each balloon...
