Stent fracture and longitudinal compression detected on coronary CT angiography in the first- and new-generation drug-eluting stents

Abstract To evaluated prevalence and clinical implication of stent fracture and longitudinal compression in first- and new-generation drug-eluting stents (DES) using coronary computed tomography angiography (CCTA). The incidence of stent fracture and longitudinal compression were compared between first- and new-generation DES in 374 patients who underwent coronary stenting using DES and follow-up CCTA due to recurrent angina. 235 and 139 patients received 322 first- and 213 new-generation DES, respectively. The crude per-stent incidence of longitudinal compression (6.1 vs. 0.3 %, p

We thank Lan éelle et al for their interest in our recent article.1 We also want to commend the authors for their excellent publication demonstrating the ability of transcutaneous oxygen pressure (TcPO2) of the calf and buttock, applied during a treadmill exercise test, to identify patients who have significan t lower extremity atherosclerotic burden as measured by computed tomography angiography.2 Both TcPO2 and near-infrared spectroscopy (NIRS) represent exciting methods to measure the balance of oxygen delivery, demand, and utilization in the legs of patients with peripheral artery disease (PAD) in rea l time.

Digital subtraction angiography (DSA) is standardly used to identify prostatic arteries during PAE, a complex task due to pelvic vascular anatomy variability (1), and an essential one given its impact on clinical outcome (2). More recently, cone-beam CT (CBCT) has been encouraged to allow identification of all vessels going to the prostate gland and their exact origin, without projection limitations due to the two-dimensional nature of DSAs (3). In this work we compare them to understand some advantages of using CBCT in PAE.

Acute intra-abdominal hemorrhage is a deadly condition and prompt diagnosis of active extravasation on CT angiography (CTA) to guide endovascular embolization can prevent significant morbidity and mortality. Convolutional neural networks (CNNs) have shown promise in automatically detecting acute radiologic findings and may hasten diagnosis and treatment of acute intra-abdominal hemorrhage.

Splenic artery embolization is essential in the nonoperative management of splenic trauma. At our institution contrast-enhanced computed tomography (CT) is performed in stable patients in the setting of blunt trauma. When active extravasation or pseudoaneurysm is identified, a code angio is initiated followed by angiographic evaluation. The operator will then select an agent for their desired target. Within our institution, glue embolization is being more frequently selected, as opposed to plugs or coils.
