Automated stenosis estimation of coronary angiographies using end-to-end learning.
Int J Cardiovasc Imaging

Novo Nordisk Foundation Center for Protein Research, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.
The initial evaluation of stenosis during coronary angiography is typically performed by visual assessment. Visual assessment has limited accuracy compared to fractional flow reserve and quantitative coronary angiography, which are more time-consuming and costly. Applying deep learning might yield a faster and more accurate stenosis assessment.

SS-OCTA was employed to assess the fundus neurovascular parameters of all participants, while the Gensini score was utilized to gauge the severity of coronary artery lesions in observation group. A total of 98 participants (49 CHD patients and 49 controls) were included.

Introduction: Deep Vein Arterialization (DVA) is an innovative surgical technique aimed at enhancing blood flow in compromised limbs facing amputation. Maintenance of flow post-revascularization is crucial to limb salvage. As this is a new technique, no standardized thromboprophylaxis regime is currently established, and post-procedure thromboprophylaxis is at the discretion of the proceduralist.

Department of Vascular Surgery, Xiamen Branch of Zhongshan Hospital, Fudan University, Xiamen, China.
Background: Endovascular recanalization with venous stenting is the preferred treatment for iliofemoral venous obstruction. We reviewed our institutional experience and mid-term outcomes with endovascular therapy for iliofemoral venous obstruction using the Venovo Self-expanding Venous Stent (BARD Peripheral Vascular, Inc., Tempe, AZ, USA).

Faculty of Medicine, Department of Urology, Yıldırım Beyazıt University, Bilkent, Polatlı caddesi, No:125/4, Gazi Mahallesi, Yenimahalle, Ankara, Turkey.
Background: To evaluate the effects of penile revascularization surgery on penile vascular hemodynamics and to assess the utility of the resistive index (RI) as an objective parameter for postoperative patient follow-up.
Methods: This study included a total of 35 patients who underwent penile revascularization. Penile color Doppler ultrasonography was performed preoperatively and at the third postoperative month to evaluate cavernosal arteries, dorsal arteries, deep dorsal vein, and inferior epigastric artery.
