[Anatomic resection of spleen in experiment]

Area of Science:

• Veterinary Surgery
• Surgical Oncology
• Abdominal Surgery

Background:

• Organ-saving surgery is crucial for maintaining splenic function.
• Detailed anatomical knowledge of splenic vasculature is essential for successful resection.
• Pre- and post-operative imaging are vital for assessing surgical outcomes.

Purpose of the Study:

• To present experimental organ-saving surgical techniques for the spleen in dogs.
• To describe methods for lobar and segmental splenic resections.
• To evaluate the efficacy of these techniques using diagnostic imaging.

Main Methods:

• Development and application of basic surgical techniques for spleen-preserving operations.
• Detailed anatomical study of splenic artery and vein branching patterns.
• Use of angiography to visualize splenic arteries post-resection.
• Ultrasonic examination before and after surgery (3-360 days) to assess spleen morphology and relationships.

Main Results:

• Successful development of experimental organ-saving spleen surgery techniques.
• Angiography clearly visualized splenic arteries, including transected stumps, after resections.
• Ultrasonic examination provided detailed pre- and post-operative data on spleen size, echostructure, and spatial relationships.

Conclusions:

• Lobar and segmental splenic resections are feasible organ-saving procedures.
• Angiography and ultrasonography are effective tools for evaluating splenic surgery.
• These techniques contribute to advancements in veterinary surgical practices for spleen conditions.
