In the Special Procedures lab, a variety of diagnostic and therapeutic procedures are performed using fluoroscopy and digital angiography. A majority of the procedures involve inserting small catheters into blood vessels and recording x-ray images of the vascular anatomy while a special substance is injected to highlight the vessels of interest.
The abdominal vessels, cerebral vessels, and the heart are often studied this way. Congenital heart disease is a common indication for diagnostic imaging in the Special Procedures lab. The procedures can provide more information about pressures within the heart chambers as well as the opportunity for interventional therapeutic procedures such as angioplasties, stent insertions, embolization procedures or coil placements. Other procedures such as biopsies, gastric tube and drainage tube insertions use the lab for its fluoroscopy and anaesthetic equipment.
The exams in the Special Procedures room combine cardiac procedures, vascular procedures, and general radiology intervention.
Cardiac exams include:
- Diagnostic cardiac catheterization
- Interventional cardiac catheterization
- Cardiac biopsies
- Transesophageal echocardiograms (TEE)
Vascular procedures include:
- Cerebral angiography
- Visceral angiography
- Vascular interventions including embolization and stenting
General Radiology intervention procedures include:
- Gastric/drainage tube insertions and replacement
- Esophageal dilatation
- Transcutaneous abscess drainages
- Transcutaneous renal/liver biopsies (ultrasound-guided)
- Transcutaneous nephrostomy
- Joint injections
