The purpose of this study was to evaluate technical and clinical results of self-expanding esophageal stent implanted in patients with malignant esophageal strictures and clinically significant dysphagia. From June 1992 to September 1994, 27 patients with inoperable tumors of the esophagus or gastric cardiac were treated by placement of 37 self-expanding nitinol stents. Water-soluble contrast and endoscopy studies were performed after the procedure and during the follow-up period. Successful stenting of the stricture was achieved in 27 patients. The mean dysphagia grade dropped from 2.3 to 1 (SD +/- 0.54) immediately after the procedure. After the insertion of the stent, 16 patients died in a period of time ranging from 0 to 13 months (mean 5.6 months), whereas at the end of the study 11 patients were alive 4-15 months after the procedure (mean 8.3 months). No major complications were observed. The results of this study are encouraging because esophageal stent placement was technically easy and clinically effective.

Development of a clinical and ultrasonic parameter-based nomogram model to predict restenosis after superficial femoral artery stenting.

Objectives: Prediction of in-stent restenosis (ISR) is clinically important for patients with peripheral artery disease in their superficial femoral arteries (SFA) who have been treated with stenting. The aim of this study was to construct and validate a predictive model for ISR after SFA stenting based on a series of clinical and ultrasonic parameters.
Methods: This retrospective study included 381 patients who were treated with self-expanding bare nitinol stents in their SFA at our hospital between January 1, 2018, and January 1, 2022.
Endovascular Preparation With Innovative Custom-Made Stent-Graft Before Kidney Transplantation: The Solution for Patients With Hostile Iliac Calcification.

The increasing age of patients with end-stage renal disease raises the issue of hostile arterial access for transplantation, with technical difficulties associated with clamping and suturing the iliac artery. Some of these patients - who theoretically represent those who would benefit the most from transplantation in terms of mortality - are contraindicated because of anatomical and medical issues. In this context, a specific endovascular device called EndoPreKiT (Endovascular Preparation for Kidney Transplantation) has been designed, enabling arterial access for transplantation via a mini-invasive procedure.

Article Synopsis
- Stent dislodgement is a rare but difficult complication during heart procedures, and existing treatment methods are not very effective.
- This study tested a new self-expanding basket (SEB) catheter designed to retrieve dislodged stents without causing additional injury or needing surgery.
- In a small trial with 6 patients, the SEB catheter successfully retrieved all dislodged stents, with no safety issues reported, indicating it may be a promising solution, but more extensive research is needed.

Background: The pRESET stent retriever is a self-expanding nitinol stent designed for mechanical thrombectomy in cases of large vessel occlusion during acute ischemic stroke. This systematic review and meta-analysis synthesize the available evidence on the safety and efficacy of the pRESET device.
Methods: This is a systematic review and meta-analysis study conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
