Correction of coagulopathy for percutaneous interventions

Area of Science:

• Interventional Radiology
• Hematology
• Coagulation Science

Background:

• Patients undergoing percutaneous interventions frequently present with abnormal hemostasis due to underlying medical conditions or pharmacotherapy.
• Etiologies include coagulation protein abnormalities, low platelet counts (thrombocytopenia), impaired platelet function, or complex conditions like disseminated intravascular coagulation.

Purpose of the Study:

• To review the fundamental science behind various causes of abnormal hemostasis in patients undergoing percutaneous interventions.
• To discuss current methods for correcting these hemostatic defects.
• To summarize evidence and guidelines for assessing and managing coagulopathy in image-guided procedures.

Main Methods:

• Literature review of basic science principles related to hemostasis.
• Review of correction strategies for hemostatic disorders.
• Analysis of current evidence and clinical guidelines for coagulopathy management in interventional radiology.

Main Results:

• Abnormal hemostasis in interventional radiology patients stems from diverse causes affecting the coagulation cascade and platelet function.
• Various therapeutic strategies exist to correct or mitigate these hemostatic abnormalities.
• Management decisions are guided by periprocedural bleeding risk and procedural urgency.

Conclusions:

• Understanding the pathophysiology of abnormal hemostasis is crucial for interventional radiologists.
• Appropriate assessment and targeted correction of coagulopathy can minimize bleeding complications.
• Adherence to evidence-based guidelines ensures optimal patient safety during image-guided interventions.
