Risk Factors IDENTIFICATION for No.pptx

Anticoagulants are drugs that inhibit the coagulation cascade to prevent thrombus formation or propagation.

1. Risk Factors IDENTIFICATION for Non-Maturation of Arteriovenous Fistulas (AVFs) .

2. Why this topic is important in vascular surgery & its rationale 1. AVF is the lifeline for patients on long-term hemodialysis. 2. High non-maturation rates (20–50%) lead to reliance on catheters → increased infection, thrombosis, and mortality. 3. Identifying risk factors early allows: 4.Better patient selection 5.Optimal pre-operative vessel mapping 6.Modification of modifiable risks (e.g., smoking, diabetes control) 7.Improved surgical planning (site choice, anastomotic technique) 8. Early interventions (angioplasty, superficialization , thrombectomy)

3. Our primary objectives in this study To understand the concept of AVF maturation Define what constitutes a mature AVF (adequate flow, diameter, usability for dialysis). To identify patient-related, vessel-related, surgical, and post-operative risk factors Categorize risk factors systematically for easy clinical application. To emphasize the role of pre-operative assessment and vessel mapping Show how early identification of risk factors guides surgical planning. To improve clinical outcomes in vascular surgery practice Reduce non-maturation rates, improve long-term patency, and enhance dialysis quality .

4. Methodology   • Study Design: (e.g., prospective observational, randomized controlled trial, retrospective study)  • Study Setting: (Hospital / Department / Duration)  • Sample Size & Sampling Technique:  • Inclusion Criteria:  • Exclusion Criteria:  • Data Collection Method: (clinical notes, imaging, follow-up, etc.)  • Variables to be Recorded: (demographics, risk factors, procedure details, outcomes, complications, etc.)  • Statistical Analysis Plan: (software, tests to be applied)

5. Ethical Considerations   • Informed consent  • Confidentiality of patient data  • Approval from institutional ethical committee

6. Expected Outcomes  • What results are expected  • How this will help improve patient care in vascular surgery
