Hemipelvectomy

Hemipelvectomy is a complex surgical procedure often performed in pets, particularly dogs and cats, to treat conditions such as tumors located on or near the pelvis. This surgery involves the removal of part or all of the pelvis and, in some cases, the attached limb. Here’s a detailed overview of hemipelvectomy, including its types, outcomes, and considerations for pet owners:

Types of Hemipelvectomy

1. External Hemipelvectomy: This involves the removal of the limb along with part or all of the pelvis. It is commonly used for treating neoplastic conditions in dogs and cats 56.
2. Internal Hemipelvectomy: This procedure spares the limb by removing only part of the pelvis. It is less common in veterinary medicine but can be used for limb preservation in selected cases45.
3. Modified Hemipelvectomy Techniques: These include procedures like partial sacrectomy and vertebrectomy, osseous excision crossing the pelvic midline, and reconstruction without local musculature. These techniques have shown good functional outcomes in dogs and cats17.

Surgical Procedure

The surgery typically involves:

• Preoperative Assessment: Blood work, imaging studies, and sometimes blood donation for potential transfusions 6.
• Surgical Steps: General anesthesia, incision, muscle dissection, ligation of major vessels, and removal of the affected pelvic segment and limb if necessary68.
• Postoperative Care: Hospitalization, pain management, and rehabilitation910.

Outcomes and Considerations

• Functional Outcomes: Many pets recover well with good mobility, especially if the procedure is well-planned and executed14.
• Complications: Potential for significant blood loss and postoperative mobility issues, especially with more extensive procedures like partial sacrectomy18.
• Owner Support: Crucial for postoperative recovery, including rehabilitation and managing potential complications910.

Advanced Hemipelvectomy Procedures

Advanced procedures involve skilled surgeons who tailor the surgery to each pet’s specific condition. These may include:

• Modified Techniques: Such as concurrent partial sacrectomy or vertebrectomy, which can improve outcomes by allowing more aggressive tumor removal while minimizing complications17.
• Limb Preservation: Internal hemipelvectomy techniques aim to preserve limb function when possible, offering a better quality of life for pets45.

In conclusion, hemipelvectomy is a viable option for treating certain conditions in pets, particularly when other treatments are not feasible. It requires careful planning, skilled execution, and dedicated postoperative care to ensure the best possible outcomes for pets undergoing this procedure.

Actionable Tips for Pet Owners:

• Consult with a Specialist: Ensure that your pet is evaluated by a veterinary surgeon experienced in hemipelvectomy procedures.
• Understand the Procedure: Discuss the specifics of the surgery, potential risks, and expected outcomes with your veterinarian.
• Postoperative Care: Be prepared to provide dedicated care and rehabilitation support to aid in your pet’s recovery.
