Objective—To describe the procedure for autologous blood donation and associated complications in cats undergoing partial craniectomy for mass removal.

Design—Prospective case series.

Animals—15 cats with intracranial mass confirmed by computed tomographic scan, no evidence of renal failure, and PCV ≥ 22%.

Procedure—One unit (60 ml) of blood was collected and stored 7 to 17 days before surgery and transfused during the perioperative period if needed. The PCV was measured before donation, before surgery, during surgery, and after surgery to assess effect of donation on PCV before surgery and effect of transfusion on PCV after surgery. Cats were evaluated for donation complications, iatrogenic anemia, and adverse reactions associated with administration of autologous blood.

Results—Complications associated with phlebotomy were not detected. Fifteen cats underwent partial craniectomy 7 to 17 days after blood donation; all had histologic confirmation of meningioma by examination of tissue obtained at surgery. Eleven cats received autologous blood transfusions. None of the cats received allogeneic blood transfusions. Transfusion reactions were not observed. Subclinical iatrogenic anemia was detected in 3 cats. Two cats were considered to have received excessive transfusion, and 3 cats received inadequate transfusion. All cats undergoing partial craniectomy were discharged from the hospital and were alive > 6 months after surgery.

Conclusion and Clinical Relevance—Autologous blood donation before surgery was considered safe for cats undergoing partial craniectomy for resection of meningioma. The only complication observed was iatrogenic anemia. The procedure contributed to blood conservation in our hospital. (J Am Vet Med Assoc 2000;216:1584–1588)

Objective—To determine results of intracranial meningioma resection by use of a surgical aspirator and assess prognostic factors associated with intracranial meningiomas in dogs.

Design—Retrospective case series.

Animals—17 dogs.

Procedures—Medical records of dogs that underwent resection of an intracranial meningioma by use of a surgical aspirator were reviewed. Information pertaining to signalment, imaging findings, clinical signs, duration of clinical signs, preoperative treatment, location of the tumor, results of histologic assessment, outcome, and necropsy results was obtained from the medical record. Clients and referring veterinarians were contacted via telephone for information on recurrence of clinical signs and postoperative survival time.

Results—16 dogs were > 7 years of age, and all 17 dogs had seizures before surgery. The most commonly affected breed was the Golden Retriever, represented by 6 of the 17 dogs. Median survival time was 1,254 days. Of the data collected, only histologic subtype of the tumor was prognostic. Analysis of survival times according to histologic tumor subtypes indicated that the order from most brief to longest was as follows: anaplastic, 0 days; fibroblastic, 10 days; psammomatous, > 313 days; meningothelial, > 523 days; and transitional, 1,254 days.

Conclusions and Clinical Relevance—Use of a surgical aspirator to resect intracranial meningiomas in dogs was associated with longer survival times than those achieved with traditional surgery alone or traditional surgery combined with radiation therapy. Dogs with meningothelial, psammomatous, or transitional intracranial meningioma subtypes appeared to have a better prognosis than dogs with other subtypes of meningioma.
