Case of the Month - October 2024

 

D - Stent obstruction and filling of tortuous venous collaterals

A non-compliant (“high pressure”) balloon catheter was then used to treat the obstruction. In this case, a 10 x 40 mm Conquest balloon catheter was used with focal waist at the caphalad end of the stent that resolved with full insufflation. Chronic more fibrous lesions often require non-compliant balloon catheters, which can generate sufficient radial force without risking balloon rupture.

Repeat venography with a pigtail flush catheter showed robust flow through a patent stent after venoplasty. The port was then removed to decrease the patient’s risk of current stenosis/obstruction.

SVC interventions are not without potential risk. What is the most catastrophic potential complication of SVC recanalization and venoplasty?

A.       Stroke

B.       Myocardial infarction

C.      Cardiac tamponade

D.      Stent migration
