Use of tissue plasminogen activator to alleviate postoperative subcutaneous ureteral bypass obstruction secondary to blood clot in seven cats

Case series summary Seven cats were found to have postoperative subcutaneous ureteral bypass (SUB) occlusion secondary to blood clot formation. An increase in serum creatinine led to imaging and clot detection in all but one case. Alteplase, a tissue plasminogen activator, was infused into the SUB via the port in four cats, intravesicularly via a transurethral urinary catheter in one cat, and by both routes in two cats. Patency of the SUB was re-established in all cats within 2 days. No short- or long-term complications directly attributed to alteplase administration were observed. Relevance and novel information The results of this case series suggest that alteplase infusion via either the SUB port and/or a transurethral catheter should be considered prior to surgical intervention for the treatment of postoperative SUB occlusion secondary to a blood clot.

Giant Omphalocele Complicated by Postoperative Duodenal Obstruction

Omphalocele is a congenital defect in the abdominal wall, usually treated at birth or within 1-2 years of life depending on condition of patient and size and contents of the defect. We repaired a giant omphalocele without mesh in a 9-year-old girl. She developed duodenal obstruction in the postoperative period requiring another laparotomy and duodeno-jejunostomy to bypass obstruction.
