[Central venous cannulation under ultrasonographic and fluoroscopic navigation - 2 year experience]

Medical professionals often face challenges in safely placing central venous catheters. Traditional blind techniques carry risks like pneumothorax and arterial puncture. While ultrasound guidance has been proposed to reduce these risks, its effectiveness compared to fluoroscopic methods remains debated. Prior research has shown that imaging technologies can improve catheter placement accuracy. However, the specific impact on complication rates in real-world clinical settings is less clear. This uncertainty drives the need for studies evaluating modern guidance systems. No prior work has resolved how ultrasonographic and fluoroscopic navigation compare in reducing early complications. The question of which anatomical approach—jugular or subclavian—yields better outcomes remains open. This gap motivated a retrospective analysis of two-year clinical data to assess complication rates under guided methods.

The researchers aimed to assess how ultrasonographic and fluoroscopic guidance affects complication rates during central venous cannulation. They focused on procedural and early postoperative complications within 24 hours. The study targeted patients undergoing central venous access, particularly oncology patients and ICU cases. The primary objective was to compare complication frequencies between jugular and subclavian approaches. The motivation stemmed from the need to improve safety in high-risk procedures. The study also aimed to evaluate the overall safety profile of guided cannulation. No prior work had directly compared these two anatomical approaches in this context. The researchers sought to provide evidence for clinical adoption of imaging-guided techniques.

The study used a retrospective design analyzing data from January 2010 to December 2011. It included patients who underwent central venous cannulation under sonographic and fluoroscopic control. The team reviewed medical records for procedural and early complications. They categorized complications such as pneumothorax, haemothorax, and soft tissue hematoma. The primary outcome was the rate of complications per cannulation attempt. They also tracked success rates and anatomical site differences. The analysis focused on 165 patients with a mix of oncology and ICU cases. The methods emphasized tracking both technical success and complication incidence.

The study found a 100% primary technical success rate across 165 cannulations. Six complications occurred (3.6% overall), including two pneumothoraxes (1.2%) not requiring drainage. Three arterial punctures occurred without hematoma development. One patient experienced a serious vagal reaction. No fatal complications were reported in the study group. The jugular approach had significantly fewer complications than the subclavian approach. The subclavian cannulations numbered only 17 compared to 148 jugular cases. These findings suggest that guided techniques reduce early procedural risks.

The authors propose that ultrasonographic guidance significantly reduces procedural complications during central venous cannulation. They observed fewer complications with the jugular approach compared to the subclavian one. The study suggests that guided cannulation is a safe alternative to traditional methods. No fatal complications were reported in the study group. The researchers recommend wider adoption of ultrasonographic navigation in emergency and ICU settings. They emphasize that guided methods may improve outcomes in non-acute cases. The findings support the use of imaging technologies to enhance procedural safety. These conclusions are based on the observed complication rates and anatomical approach differences.
