Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

Catheter-based Endovascular Angioplasty for Fibrosing Mediastinitis-associated Pulmonary Vein Stenosis

2025
Pulmonary vein stenosis (PVS) is a life-threatening complication of fibrosing mediastinitis (FM), with a poor prognosis if not properly treated. Currently, catheter-based endovascular angioplasty is a promising therapeutic strategy for FM-associated PVS. This protocol primarily outlines a stepwise approach to the transcatheter procedure for FM-associated PVS.

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Monitoring Animals for Signs of Pain and Distress Recognizing early signs of pain is essential for ethical animal research. Animals are routinely monitored using behavioral, physical, and physiological parameters that reflect...
FAQs
Imaging guidance allows clinicians to monitor catheter position as it advances through a blood vessel or other anatomical pathway and align the device with the intended site. This control supports localized delivery of instruments, medications, energy, or implants rather than requiring broad access to the surrounding area. The procedure therefore depends on accurate navigation as well as the catheter itself.
The catheter’s thin, flexible design is central to access. It can be directed through existing anatomical pathways while supporting different interventions, including vascular treatment, cardiac repair, tissue sampling, or drainage. This combination of navigability and varied functions explains why the same general approach can serve both diagnostic and treatment goals across multiple medical settings.
Compared with conventional open surgery, catheter-based interventions aim to reach a target through an anatomical pathway rather than by creating an open surgical access route. That difference can reduce tissue disruption and may support shorter recovery time and lower procedural risk. The relative advantages depend on the condition being addressed and the intervention required.
Imaging, catheter design, and robotic guidance are expanding the range of sites clinicians can reach and the procedures they can perform. Improved imaging supports navigation, while new catheter designs and robotic systems can extend procedural capabilities. These developments help explain why catheter-based interventions continue to grow in importance within modern medicine.
A typical intervention begins by selecting access through a blood vessel or another anatomical pathway. Clinicians then guide the catheter under imaging toward the target and perform the selected diagnostic or therapeutic task. Depending on the clinical goal, the procedure may involve tissue sampling, vascular treatment, cardiac repair, drainage, or delivery of medication, energy, or an implant.
Clinicians may consider this approach when a condition can be reached through a blood vessel or another anatomical route and when targeted action is useful. The method supports diagnosis through tissue sampling and treatment through vascular procedures, cardiac repair, drainage, or delivery of medications, energy, and implants. Its usefulness comes from matching access to the clinical target.
Applications include vascular treatment, cardiac repair, tissue sampling, and drainage, with additional procedures using catheters to deliver medications, energy, or implants. Because these approaches avoid open surgery, they can limit tissue disruption and potentially shorten recovery compared with conventional surgery. Imaging and guidance advances continue to broaden their role in clinical care.
