Article Abstract
Background: Central venous access for cardiac implantable electronic device (CIED) implantations is conventionally acquired via the cephalic or subclavian vein. Controlled data suggest that axillary vein access may reduce complications.
Objectives: We, therefore, shifted institutional practice from subclavian vein access to ultrasound (US)-guided axillary vein access for new implantations and revisions or upgrades and report on implant success rates, learning curves and periprocedural complications.
Methods: Between January 2021 and August 2023, all patients undergoing CIED implantations, revisions or upgrades were analyzed. US-guided axillary access was introduced starting with one operator and spreading to most operators and trainees thereafter. Periprocedural outcomes and complications (pocket hematoma, hemothorax, and pneumothorax) of transcutaneous US-guided axillary vein access were compared to the subclavian vein access.
Results: In this study, 986 patients (median age: 75 years, interquartile range (IQR) 64-82 years, 35% women) with 87% new implantations and 13% revisions or upgrades were included. Transcutaneous US-guided axillary access was successful in 535/578 patients (93%), subclavian vein access in 400/408 patients (98%) (p < 0.001). For device upgrades or revisions specifically, axillary access was successful in 69/79 patients (87%), versus 45/47 patients (96%) with subclavian access (p = 0.208). The learning curve for axillary access was steep with success rates of 93 after 30 cases per operator. Complications occurred in 2/578 patients (0.3%) undergoing axillary vein access versus 17/408 patients (4.2%) (p < 0.001) undergoing subclavian vein access.
Conclusion: The implementation of transcutaneous US-guided axillary vein access for implantation, revisions and upgrades of cardiac electronic devices is feasible in a large tertiary care center. The periprocedural complications are rare.

Debilitated calves are often presented with an umbilical remnant infection, septic arthritis, or both. These comorbidities, frequently caused by similar bacteria, must be addressed surgically. In cases of omphalophlebitis where the infection reaches the liver, the clinician generally has 1 option: marsupialization of the vein.

Tuberculosis (TB) is a multisystem infectious disease with both pulmonary and extrapulmonary manifestations. TB can also induce a hypercoagulable state, setting off a cascade of changes in the body, including systemic inflammation, endothelial dysfunction, and abnormalities in the coagulation and fibrinolytic pathways. Collectively, these factors significantly increase the risk of venous thromboembolism, such as deep vein thrombosis and pulmonary embolism.

Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. The tumor microenvironment (TME), particularly the interactions between endothelial cells and cancer-associated fibroblasts (CAFs), plays a pivotal role in promoting tumor growth, angiogenesis, oxidative stress, and therapy resistance. The HUVEC-fibroblast co-culture model closely mimics stromal-endothelial interactions observed in CRC, enabling mechanistic insights not achievable in monocultures.

A profound understanding of pancreatic anatomy and its vascular supply is essential for safely performing complex surgical procedures such as pancreaticoduodenectomy. Historically, anatomical exploration began with Herophilos and Ruphos of Ephesos in ancient times, evolving through major surgical innovations by Wirsung, Kausch and Whipple. The pancreas is located secondarily retroperitoneally and therefore has a close relationship of the pancreatic head to the superior mesenteric artery (SMA) and portal vein (PV) and the celiac trunc.

Objective: Telehealth preoperative evaluations have been shown to improve access to care, reduce appointment cancellations, and support efficient procedural planning across multiple surgical subspecialties. However, few studies have assessed the safety and efficacy in patients undergoing elective cardiac surgery.
Methods: We conducted a retrospective multi-institutional cohort study comparing procedural and postoperative outcomes for patients who had telehealth versus in-person preoperative evaluations for elective cardiac surgery between March 1, 2020, and March 1, 2021.
