Case of the Month - November 2024
E. A and c
“Pre-emptive TIPS” for prevention of recurrent variceal bleeding has been shown to be beneficial for patients with Child Pugh C cirrhosis or those with Child Pugh B cirrhosis with evidence of bleeding on endoscopy. This can also be performed outpatient (“elective TIPS”). Early TIPS in these patients was shown in a study to have less rebleeding (3% vs 50%) and time in the hospital (4 vs 15 days) with superior 1 year survival (86% vs 61%) compared to medical management.
The patient ultimately underwent a retrograde transvenous obliteration via common femoral venous access. A curved 9 Fr sheath was placed at the origin of the left renal vein and a 4 Fr C2 catheter was used with an angled glidewire to select the outflow of the gastrorenal shunt. Further catheter purchase into the shunt allowed passage of a stiff working wire to advance an 8 Fr balloon catheter into the shunt for venography.
Sclerosis was then performed using a 3-2-1 ratio of air, STS, and lipiodol. After injection of ~18 mL sclerosant under fluoroscopic monitoring, the following is observed. Further injection is stopped and the system is allowed to passively decompress through the balloon catheter.
What potential complication would occur with further injection of sclerosant at this point?
A. Portal venous thrombosis
B. Stroke
C. Pulmonary embolism
D. Renal vein thrombosis
