Splenic Torsion

What It Is

Splenic torsion is rotation of the spleen around its vascular pedicle, causing venous obstruction, splenic congestion, impaired blood flow, enlargement, pain, shock risk, and potential association with gastric dilatation-volvulus.

Also Called: twisted spleen; splenic volvulus

Breeds Affected: Greater Swiss Mountain Dog


The Idiot-Proof Explanation

The spleen twists on itself and its blood supply gets kinked. Blood gets trapped, the spleen swells, the dog gets sick, and sometimes this shows up alongside bloat. It is not a “tummy ache.” It is an abdominal emergency wearing a very dramatic hat.


What Causes It

Splenic torsion can occur on its own or with gastric dilatation-volvulus. Large, deep-chested dogs are the classic concern.

When the spleen twists, drainage is blocked. The spleen becomes enlarged, congested, painful, and unhealthy, and the dog may become systemically ill.

  • The spleen rotates around the blood vessels that supply and drain it.
  • The condition may occur alone or in connection with GDV.
  • Large, deep-chested dogs are higher risk.
  • Delayed treatment can lead to shock, tissue compromise, and major abdominal surgery.

If an at-risk dog looks acutely sick with abdominal signs, this belongs in the emergency lane.


What This Means for Life With This Dog

Life with splenic torsion is usually not long-term management first. It is “why is my dog suddenly sick and what emergency hospital is open?” territory.

Signs can be vague at first: lethargy, appetite loss, vomiting, abdominal discomfort, weakness, pale gums, or collapse. Vague does not mean harmless.

Treatment often means surgery to remove the spleen, plus stabilization and monitoring for shock, bleeding, arrhythmias, or related GDV concerns.


Can It Be Fixed?

Splenic torsion is usually treated surgically with splenectomy after stabilization. If GDV is involved, the dog may also need emergency GDV surgery and gastropexy.


Symptoms Owners May Notice

Lethargy or sudden weakness: The dog may seem abruptly dull, weak, unwilling to move, or just deeply wrong in that way owners notice before they know the medical term.

Vomiting or poor appetite: GI signs may show up because the abdomen is angry and the spleen is not having a normal day.

Abdominal pain or swelling: The belly may be painful, tense, enlarged, or uncomfortable when touched.

Pale gums or collapse: Shock signs are an emergency. Pale gums, collapse, rapid heart rate, or severe weakness means the clock is not your friend.


Treatment Options

Emergency stabilization: Care starts with exam, IV fluids, bloodwork, imaging, pain control, and stabilization, especially if shock or GDV is possible.

Surgery: The twisted spleen is commonly removed. If the stomach is involved, GDV surgery and gastropexy may be part of the same nightmare invoice.

Post-op monitoring: After surgery, dogs may need monitoring for bleeding, arrhythmias, infection, anemia, pain, and overall recovery from a major abdominal event.


Recovery and Aftercare

Aftercare means incision care, activity restriction, medication, rechecks, and watching appetite, gum color, energy, and breathing. This is not a “he had a spleen removed yesterday, let him gallop” situation.


What Happens If You Wait

Waiting can turn a surgical problem into a shock problem.

Delayed care can mean worsening pain, vascular compromise, systemic illness, collapse, or death, especially if GDV is also in the picture.


Cost Reality Check

Splenic torsion costs depend on whether it is isolated, whether GDV is involved, how sick the dog is at arrival, and how long hospitalization is needed.

Care Level What It May Include Estimated Cost
Initial workup Emergency exam, bloodwork, imaging, IV fluids, pain control, and stabilization. $800-$2,500
Ongoing management Surgery, anesthesia, splenectomy, hospitalization, medication, and routine post-op care. $3,000-$7,000+
Severe case Complicated emergency surgery with GDV, shock, transfusion needs, arrhythmias, or prolonged hospitalization. $6,000-$15,000+

GDV involvement: A twisted spleen is bad. A twisted spleen plus a twisted stomach is the deluxe disaster package.

Stability at arrival: A stable dog costs less than one arriving collapsed, shocky, or requiring intensive care.

Need for transfusion: Anemia, bleeding risk, or severe compromise can add blood products and monitoring.

Hospitalization length: More days in ER/specialty care means more cost. Very shocking, said no one who has ever seen an emergency bill.


Budget Reality Check

Budget Item Estimated Cost
Emergency exam and diagnostics $500-$1,500+
Stabilization and IV care $500-$2,000+
Splenectomy surgery $3,000-$7,000+
Hospitalization and monitoring $1,000-$4,000+
Complicated GDV-related care $6,000-$15,000+

Lifetime Cost Reality

Case Pattern Possible Lifetime Cost
Isolated early surgical case $3,000-$7,000+
Emergency complicated case $5,000-$12,000+
GDV-associated crisis $8,000-$20,000+

Tell Me What I Should Really Expect

Splenic torsion is not a home-monitoring hobby.

A dog with possible splenic torsion needs emergency evaluation. The vague signs are exactly why owners miss it. Unfortunately, the abdomen does not hand out neat little warning labels before it starts ruining everyone’s day.
