Hemoabdomen & Hemoperitoneum: Abdominal Bleeding in Cats

Cats

Overview of Abdominal Bleeding in Cats

Hemoperitoneum (also commonly called hemoabdomen) is defined as blood within the cat's peritoneal (abdominal) cavity. It occurs following intra-abdominal hemorrhage as blood accumulates in the space between the abdominal wall and the abdominal organs.

Some causes of hemoperitoneum in cats include:

Traumatic injury – the most common cause of hemoperitoneum.

Intra-abdominal tumors – may rupture, bleed slowly, or invade into a blood vessel, causing blood to accumulate in the abdomen.

Hematomas – organized, local collections of blood that can rupture and bleed.

Coagulopathies – clotting disorders that can cause bleeding within the abdomen as well (as in other sites).

Depending on the rapidity and extent of the blood loss, hemoperitoneum may be an emergency situation.

Signs to Watch For

Weakness

Collapse

Abdominal distension

Bruising under the skin

Increased respiratory efforts

Pale mucus membranes (the best place to check is the inner lining of the lips and gums)

Other signs that might indicate more gradual blood loss include: anorexia, lethargy, intermittent weakness, and weight loss.

Diagnostic Tests for Hemoabdomen & Hemoperitoneum in Cats

A thorough history and physical exam is critical for prompt and accurate diagnosis. Your veterinarian may also recommend:

Abdominal X-rays

Abdominocentesis – inserting a needle and syringe into the abdominal cavity to obtain a fluid sample for diagnostic evaluation

Analysis of the retrieved sample for evaluation

Complete blood count

Depending on your pet's condition and initial test results, additional testing may be required. Such testing may include:

Biochemistry profile

Coagulation panel

Abdominal ultrasound

Computed tomography (CT) or magnetic resonance imaging (MRI)

Treatment of Hemoabdomen & Hemoperitoneum in Cats

The general approach to treatment varies on the clinical condition of the patient and the cause of the hemoperitoneum. Therapy may include:

Abdominocentesis (if pressure on the diaphragm is impeding respiration)

Intravenous fluid therapy

Blood transfusion

Belly wrap

Oxygen therapy

Analgesic therapy (pain medication)

Vitamin K administration

Emergency exploratory surgery

Home Care

Hemoperitoneum may be an emergency situation. Veterinary care should be sought as soon as possible. Keep your pet calm, comfortable and warm. Minimize stress until you can get to a veterinary hospital. If a traumatic injury is suspected, be careful moving your pet as spinal injury or fractures may be present.
