Outcomes after open and endovascular treatment for mesenteric artery embolism patients: a retrospective inverse probability of treatment-weighted analysis.

Purpose: This study aims to evaluate outcomes in patients with mesenteric artery embolism (MAE) who received primary endovascular therapy (EVT) or laparotomy, and investigate risk factors for 30-day mortality.

Methods: A retrospective analysis of 94 MAE patients who underwent two different treatment strategies was undertaken. An inverse probability of treatment weighting (IPTW) method was used to balance the confounding effects of baseline clinical data.

[Anesthesia and operative approach of resection of the trachea].

Objective: Review and discuss anesthesia and operative approach of resection of the trachea for different tracheal diseases, especially for the resection of long-segment of trachea. At the same time to introduce the method of reconstruction of long-segment of trachea with Zhao's (two-stage procedure with memory-alloy mesh) artificial trachea.

Methods: Retrospective study of 18 cases of tracheal resection, analysis of the relation between the choice of anesthetic and operative approach.

[Replacement of artificial tracheal prosthesis by two-stage procedure with memory-alloy mesh].

Objective: To design an artificial trachea which can totally heal with the native trachea.

Methods: Using memory-alloy mesh as the skeleton to construct an artificial trachea by two-stage operation. After 2-year animal experiment we successfully performed the operation in a patient with recurrent carcinoid of the trachea, radically resected the tumor and primarily reconstructed the trachea.
