Ambulatory Venous Hypertension
Components
• Obstruction
• Valve incompetence
• Obstruction and valve incompetence
…Highest venous pressure
…Most severe morbidity
Iliofemoral DVT
Contraindication to Lysis
Yes
No
Surgical Thrombectomy
+ AVF
Catheter-directed
Thrombolysis
No
Anticoagulation
Success
Yes
Venous Thrombectomy vs. Anticoagulation
Randomized Trial
• 63 patients: iliofemoral DVT
• Thrombectomy + AVF vs. Anticoagulation
• Follow-up: 6 mos, 5 yrs, 10 yrs
• Patency
– Valve function
– Venous hemodynamics
– Clinical evaluation

Acute DVT
Thrombolytic Therapy: ACCP 2004
“…There is no evidence that supports
the use of thrombolytic agents for the
initial treatment of DVT….”
Recommend against the routine use of catheterdirected thrombolysis (Grade 1C)
…Treatment..[with lytic Rx] .. Be confined to
patients requiring limb salvage. (Grade 2C)

Catheter-Directed Lysis Iliofemoral DVT
Improvement in Quality of Life
• Significantly better QOL with lysis
Physical function
Stigma
Health distress
Post thromb Sx
• Successful lysis correlated w/QOL
• Lytic failures and heparin Rx similar

Catheter-Directed Lysis Iliofemoral DVT
Improvement in Quality of Life
• 35 consecutive patients
• Iliofemoral DVT
• Randomized
Cath-dir SK (pulse spray)
vs.
Anticoagulation alone
• Follow-up 1week/6mos
– Clot lysis
– Venous reflux
