Published: August 1998

In order to find risk factors of carotid endarterectomy related stroke (CERS), 102 consecutive carotid endarterectomies, performed within two years on 95 patients were analyzed. Age, sex, diabetes, smoking, hypertension, degree of the operated and non operated carotid stenosis, previous neurological symptoms, anesthesia, protamine, cerebral monitoring, shunt, patch, post op. hypertensive crisis and clamping time were compared with the incidence of CERS. Four patients had major neurological deficits, two of which were fatal (3.92%). Six patients had minor transitory neurological deficit (5.8%). The use of patch and a long clamping time were the only identifiable statistically significant factors (p = 0.016 and p = 0.0053 respectively) that increase the odds of a CERS.

Background: Fear and horror induce autonomic protective responses, acting as "survival intelligence." Pupillometry is an innovative method that captures real-time autonomic nervous system reactions to stress.

Objective: To evaluate the feasibility of pupillometry to assess the acute response to a passive real-life stressor-viewing a truthful war scene.

Aim: To improve delayed cord clamping (DCC) rates for preterm infants (≤ 34 + 0 weeks' gestation) and establish DCC as standard practice using quality improvement (QI) methods.

Methods: A multi-departmental initiative was undertaken. An audit of DCC for preterm infants born at or before 34 + 0 weeks was performed.

Objective: Laparoscopic nephron sparing surgery (NSS) can be performed by mainly 2 methods, offclamp or on-clamp. Continuous bleeding during the off-clamp method may impair the clear visualization of the border between the tumor and parenchyma, even though it is done safely in experienced hands. Therefore, some surgical modifications may be needed during mass excision and renorraphy.

Objective: We aimed to explore the application value of unsupervised machine learning in identifying acute gastrointestinal injury (AGI) after extracorporeal circulation for acute type A aortic dissection (ATAAD).

Methods: Patients who underwent extracorporeal circulation for ATAAD at the First Hospital of Lanzhou University from January 2016 to January 2021 were included. Unsupervised machine learning algorithm was used to stratify patients into different phenogroups according to the similarity of their clinical features and laboratory test results.

Background: End-Stage Renal Disease (ESRD) is an independent risk factor in outcomes for traditional coronary artery bypass grafting (TRAD-CAB) utilizing aortic cross-clamping and cardioplegic arrest. In order to determine if Beating-Heart CABG (BH-CABG) techniques offer benefit in patients with ESRD, an analysis of the Society of Thoracic Surgeons (STS) predicted risk versus the actual outcomes was performed.

Methods: Between March 2017 - October 2023, all ESRD patients underwent BH-CABG by a single surgeon at a single institution.
