Interventional radiology (IR) is a medical field where minimally invasive diagnostic, therapeutic, and curative procedures are performed under the guidance of medical imaging. Rather than resorting to traditional open surgery, interventional radiologists use small incisions, typically in the abdominal area, to navigate catheters through blood vessels, arteries, and organs, all while leveraging advanced medical imaging techniques.¹This approach allows patients to avoid the drawbacks of costly, painful, and risky surgical procedures. As a result, IR has become a preferred treatment option for a wide range of medical conditions, and its repertoire of effective therapies continues to expand. Some examples of interventional radiology procedures include angioplasty: used to repair or unblock blood vessels, stenting involves the placement of tiny mesh tubes to treat narrowed or weakened arteries, thrombolysis: the process of dissolving blood clots, embolization: utilized to block blood flow to cancer cells, radiofrequency ablation: applied to reduce nerve pain, biopsies: used for the study of tissues.¹IR has revolutionized the way medical conditions are treated, offering patients less invasive, highly effective alternatives to traditional surgery.¹Haemostat’s can be a valuable device in interventional radiology procedures to help control bleeding and achieve haemostasis (the cessation of bleeding) at the puncture or access site. One such haemostat is Axiostat, chitosan based haemostatic dressing based on Protonated Bio adhesive Polymer technology (PBT) to make its biopolymer-based haemostats with tailorable bio adhesive properties. The synergistic impact of bio adhesion and the potent blood clot results in immediate haemostasis.²

Case study: AXIOSTAT – 100% CHITOSAN HAEMOSTATIC DRESSING ON BLEEDING DUE TO CENTRAL VEINOPLASTY

The patient was 37 years old male with renal hypertension. The procedure includes central veinoplasty and stenting with heparin dosage (5000IU) followed by 2-minute average time taken to achieve haemostasis.³

Application of Axiostat with a uniform pressure

The haemostasis time was considerably less than the traditional procedure of manually compressing the wound using cotton gauze, which typically takes 20 minutes to complete.After withdrawing the physical compression, no further bleeding from the puncture sites was noticed for an additional 2-3 hours of monitoring. Likewise, after the removal of Axiostat, the puncture sites did not exhibit any subsequent bleeding, skin rashes, swelling, vascular complications, or allergies.³Additionally, during the five days following the operation, there were no incidents of device-related bleeding problems.3 Overall, it was observed that patients undergoing interventional radiology treatments with Axiostat had excellent haemostatic results.
