Pre-Procedure TIPS Patient Assessment
For elective TIPS, obtain contrast-enhanced multiphasic cross-sectional imaging (CT or MRI) and comprehensive echocardiography; for emergent TIPS, at minimum perform liver ultrasound with Doppler and consider bedside echocardiogram. 1
Essential Pre-Procedure Imaging
Elective TIPS Setting
- Contrast-enhanced multiphasic CT or MRI to evaluate portal venous anatomy, assess for portal vein thrombosis, identify hepatic lesions/cysts that could preclude TIPS creation, and assist with procedural planning 1
- Comprehensive echocardiography to assess:
- Left ventricular ejection fraction and cardiac structure
- Right ventricular systolic pressure
- Valvular heart disease severity
- Overall cardiac function 1
Emergent TIPS Setting
When time is limited, clinical judgment should guide the workup, but at minimum obtain:
- Liver ultrasound with Doppler to evaluate portal venous system patency
- Limited (bedside) echocardiogram focusing on left ventricular ejection fraction and right ventricular systolic pressure 1
Clinical Assessment and Risk Stratification
Multidisciplinary Evaluation
Rather than relying on absolute MELD cutoffs, use a multidisciplinary approach involving Gastroenterology/Hepatology, Cardiology, Pulmonary, and potentially Nephrology and Critical Care to assess TIPS candidacy 1. This is particularly important for:
- Patients requiring higher levels of care
- Potential liver transplant candidates
- Patients with extensive portal vein thrombosis requiring specialized IR expertise 1
Absolute Contraindications to Screen For
The pre-procedure assessment must identify these absolute contraindications 1:
Cardiac:
- Severe congestive heart failure (ACC/AHA Stage C or D)
- Severe untreated valvular heart disease (AHA/ACC stage C or D)
- Moderate-severe pulmonary hypertension (based on invasive measurements) despite medical optimization
Hepatic:
- Refractory overt hepatic encephalopathy
- Unrelieved biliary obstruction
- Hepatic lesions (cysts) or tumors in the liver parenchyma that preclude TIPS creation
Systemic:
- Uncontrolled systemic infection
Laboratory Assessment
While specific thresholds are not definitively established, baseline laboratory evaluation should include:
- Complete blood count
- Coagulation parameters (INR, though no specific target INR is recommended for correction) 1
- Comprehensive metabolic panel including liver function tests
- MELD score calculation for risk stratification 1
Important caveat: There is insufficient evidence to recommend specific target INR or platelet thresholds prior to TIPS placement 1. The decision to correct coagulopathy should be individualized based on patient and procedural factors.
Liver Transplant Evaluation Consideration
There is insufficient evidence to recommend universal pre-procedure liver transplant evaluation for all patients undergoing elective or emergent TIPS 1. However, in patients who may be transplant candidates or those with advanced liver disease, referral to centers with transplant expertise should be considered.
Common Pitfalls to Avoid
- Don't skip cardiac evaluation in elective cases: Cardiac complications post-TIPS can be catastrophic. Comprehensive echocardiography is essential, not optional 1
- Don't delay emergent TIPS for extensive workup: In acute variceal bleeding, limited but focused assessment (Doppler ultrasound and bedside echo) is acceptable 1
- Don't rely solely on MELD score: A multidisciplinary assessment considering overall clinical status, cardiac function, and hepatic reserve is superior to any single cutoff 1
- Don't overlook anatomical barriers: Cross-sectional imaging may reveal portal vein thrombosis, hepatic lesions, or anatomical variants that could make TIPS technically impossible or contraindicated 1
The most recent 2025 EASL guidelines 2 emphasize post-procedural monitoring but defer to the comprehensive 2022 North American recommendations 1 for pre-procedure assessment, which provide the most detailed and evidence-based framework for patient evaluation.
