Novel approach to treating calcified infrarenal aortic stenosis using intravascular lithotripsy without stenting.
J Vasc Surg Cases Innov Tech
April 2025
Vascular Surgery Unit, S. Chiara Hospital, APSS Trento, Trento, Italy.
This case report presents the use of intravascular lithotripsy (IVL) in a 68-year-old woman with disabling bilateral claudication owing to a heavily calcified subocclusive stenosis of the infrarenal aorta. The patient had a history of tobacco use, dyslipidemia, and chronic obstructive pulmonary disease, with absent femoral pulses and severe arterial calcification. A 12-mm Shockwave L6 lithotripsy catheter was employed to treat the aortic lesion, resulting in a significant decrease in the aortic pressure gradient without the need for stenting.

Heart Center, Women and Children's Hospital, Qingdao University, Qingdao, China.
Background: This study aimed to assess right ventricular (RV) endocardial fibroelastosis (EFE) in fetuses with critical pulmonary stenosis (CPS) and pulmonary atresia with intact ventricular septum (PA-IVS) and to investigate the implications of RV EFE for circulatory outcomes.
Methods: Fetal echocardiographic data from July 2018 to January 2021 were collected. Three reviewers independently graded EFE based on the presence and extent of endocardial echogenicity.
In image-guided radiotherapy (IGRT), four-dimensional cone-beam computed tomography (4D-CBCT) is critical for assessing tumor motion during a patients breathing cycle prior to beam delivery. However, generating 4D-CBCT images with sufficient quality requires significantly more projection images than a standard 3D-CBCT scan, leading to extended scanning times and increased imaging dose to the patient. To address these limitations, there is a strong demand for methods capable of reconstructing high-quality 4D-CBCT images from a 1-minute 3D-CBCT acquisition.

Department of Oncology, Wenzhou Traditional Chinese Medicine Hospital of Zhejiang Chinese Medical University, Wenzhou, China.
Background: Hyperammonemic encephalopathy caused by high-dose infusion of 5-fluorouracil (5-FU) is a rare adverse reaction in rectal cancer patients with an incidence rate of 5.7%. Although the patient could be restored to normal after supportive treatments, the occurrence of this side effect was still inevitable.
