Peripherally inserted central-related upper extremity deep vein thrombosis and machine learning.

Objective: To establish a prediction model of upper extremity deep vein thrombosis (UEDVT) associated with peripherally inserted central catheter (PICC) based on machine learning (ML), and evaluate the effect.

Methods: 452 patients with malignant tumors who underwent PICC implantation in West China Hospital from April 2021 to December 2021 were selected through convenient sampling. UEDVT was detected by ultrasound.

Aggressive surgical approach with vascular resection and reconstruction for retroperitoneal sarcomas: a systematic review.

Background And Aim: Surgery is the mainstay of treatment and completeness of surgical resection is critical to achieve local control for retroperitoneal sarcoma (RPS). En-bloc resection of adjacent organs, including major abdominal vessels, is often required to achieve negative margins. The aim of this review was to summarise the available evidence to assess the relative benefits and disadvantages of an aggressive surgical approach with vascular resection in patients with retroperitoneal sarcoma (RPS).

Incidence, risk factors, and outcomes of venous thromboembolism in patients undergoing surgery for retroperitoneal tumors: a propensity-matched retrospective cohort study.

Background: Venous thromboembolism (VTE) is a common postoperative complication; however, the incidence and risk stratification of postoperative VTE in patients with retroperitoneal tumor remains unclear. The authors aim to quantify the incidence, identify risk factors, and determine the outcomes of VTE in patients undergoing retroperitoneal tumor surgery.

Methods: The authors retrospectively reviewed the characteristics, perioperative outcomes, and overall survival (OS) of patients (VTE and non-VTE) who underwent retroperitoneal tumor surgery between 2015 and 2020.

An Evidenced-Based Review of Emergency Target Blood Pressure Management for Acute Aortic Dissection.

Objective: To summarize the best evidence of emergency target blood pressure management for acute aortic dissection and provide guidance for evidence-based practice of emergency target blood pressure management.

Methods: According to the "6S" evidence pyramid model, the evidence of emergency target blood pressure management of acute aortic dissection in various foreign databases and websites of professional associations from January 1, 2010, to August 1, 2022, was retrieved, including clinical decision-making, guidelines, expert consensus, systematic reviews, randomized controlled trials, cohort studies, and case series. Two researchers used the corresponding document quality evaluation tools to evaluate the documents and extracted and summarized the evidence of documents above grade B.

Reconstruction of the accessory renal artery with autogenous vessels in aortic hybrid surgery: A case report.

Objective: Accessory renal artery (ARA) is a common variant of renal vessels. Currently, there are some controversies about reconstruction strategy and few cases reported in the literature. Individualized treatment should be carried out according to preoperative renal function evaluation and technical level.

The strategies and outcomes of left subclavian artery revascularization during thoracic endovascular repair for type B aortic dissection.

This study was to analyze the outcomes of left subclavian artery (LSA) revascularization during thoracic endovascular repair (TEVAR) for type B aortic dissections (TBAD). From 2011 to 2017, TBAD patients who underwent LSA revascularization during TEVAR were enrolled. Technical success, endoleaks, mortality, complication, reintervention, and patency of target vessels were analyzed.

Liver autotransplantation and retrohepatic vena cava reconstruction for alveolar echinococcosis.

Background: Alveolar echinococcosis (AE) is characterized by a slow-growing infiltrative neoplasm that is often unresectable by traditional methods because of strong adhesions and invasion to adjacent structures. We present our experience with liver autotransplantation and retrohepatic inferior vena cava (RHIVC) reconstruction using autogenous veins in patients with this end-stage parasitic disease.

Methods: Twelve patients with hepatic AE and extensive RHIVC, hepatic vein, and/or hilar invasion underwent ex vivo liver resection and RHIVC reconstruction using autogenous veins followed by autotransplantation in the West China Hospital of Sichuan University from 2013 to 2016.

En Bloc Resection with Major Blood Vessel Reconstruction for Locally Invasive Retroperitoneal Paragangliomas: A 15-Year Experience with Literature Review.

Background: Retroperitoneal paragangliomas (PGs) are a rare subgroup of neuroendocrine tumors that are commonly located alongside the abdominal aorta. Complete tumor resection is thought to be restricted in patients with major blood vessel involvement. However, no study has specifically focused on aggressive surgical treatment in such patients.

Predictors for mortality following acute pancreatitis in children.

Introduction: Although there are several studies focusing on pancreatitis etiology and clinical outcome, no previous report has examined the risk factors for death in children.

Patients And Methods: We reviewed the medical records of all children (ages 0-18 years) admitted to West China Hospital with acute pancreatitis between 2002 and 2012. Independent predictors for death following acute pancreatitis in children were identified using a multivariate logistic regression analysis.

A minimally invasive management for abdominal compartment syndrome in severe acute pancreatitis.

Three patients with severe acute pancreatitis (SAP) developed into overt abdominal compartment syndrome (ACS) and confirmed or suspected infection of necrotic tissue. We successfully treated these patients by minimally invasive decompression with the assist of laparoscope after the failures of intensive care treatments. This technique we report here may be another safe and effective management for ACS in SAP.
