Outcome following splenectomy in cats.

Area of Science:

• Veterinary Medicine
• Surgical Oncology
• Canine and Feline Health

Background:

• Splenectomy is a common surgical procedure in veterinary medicine.
• Prognostic factors for feline splenectomy survival remain unexamined.
• Common indications include neoplastic conditions like mast cell tumors and hemangiosarcoma.

Purpose of the Study:

• To identify prognostic factors for survival in cats following complete splenectomy.
• To analyze the impact of preoperative, intraoperative, and postoperative variables on survival time.

Main Methods:

• Retrospective review of medical records for 19 cats that underwent complete splenectomy.
• Kaplan-Meier survival analysis was used to determine median survival time (MST).
• Statistical analysis was performed to assess the significance of various factors.

Main Results:

• The overall median survival time (MST) was 197 days.
• Mast cell tumors were the most frequent reason for splenectomy (53%).
• Preoperative weight loss was the only statistically significant negative prognostic factor (P=0.008), with an MST of 3 days versus 293 days for cats without weight loss.

Conclusions:

• Preoperative weight loss is a critical indicator of poor prognosis in cats undergoing splenectomy.
• Further research is warranted to explore underlying mechanisms and improve outcomes for affected cats.
• This finding aids in preoperative counseling and risk assessment for feline splenectomy patients.
