Life-saving pulmonary embolism prevention when blood thinners can't be used
Deep vein thrombosis (DVT) is increasingly common in Pakistan due to factors like genetic predisposition, sedentary lifestyles, and certain medical conditions. When blood clots form in deep veins (usually legs), they can break loose and cause life-threatening pulmonary embolism (PE).
An IVC (inferior vena cava) filter is a small metal device placed in the main abdominal vein to catch blood clots before they reach the lungs. This minimally invasive procedure is crucial when blood thinners can't be used - a common scenario in trauma patients or before certain surgeries in Pakistan.
• Comprehensive evaluation including ultrasound/CT venography
• Blood tests (coagulation profile, renal function)
• NPO (nothing by mouth) for 6 hours before procedure
• Review of medications (especially blood thinners)
• Informed consent discussion
• Local anesthesia with sedation (rarely general anesthesia)
• Small puncture in groin or neck (1-2mm)
• Catheter guided to IVC under fluoroscopic imaging
• Filter deployed in precise position below renal veins
• Confirmation of proper placement with imaging
• Procedure duration: 30-60 minutes
• 4-6 hours bed rest to prevent access site bleeding
• Monitoring for complications (rare)
• Discharge same day or next morning
• Follow-up imaging as needed
• For retrievable filters: planned removal when no longer needed
Costs vary by hospital and filter type but are significantly more affordable than in Western countries. Many insurance plans cover this procedure when medically necessary. Emergency cases are prioritized at our facility.
IVC filter placement requires specialized interventional radiologists and is primarily available at major medical centers in Karachi, Lahore, and Islamabad. Our facility performs this procedure routinely with excellent outcomes.
Permanent filters are designed to remain for life. Retrievable filters should be removed within 3-6 months typically, though some newer models can stay longer. We schedule follow-ups to determine optimal removal timing.
Filters don't treat DVT - they only prevent PE. When the bleeding risk passes, anticoagulation is usually started to treat the existing clot. We develop personalized plans for each patient's situation.
Seek immediate care for:
30-60 minutes
90-95% PE prevention
Outpatient or 1 night
1-2 days
Local with sedation
