Rectus sheath hematoma is a condition in which bleeding occurs within the sheath surrounding the rectus abdominis muscles. The condition may develop after injury, sudden muscle strain, or spontaneous bleeding, particularly in people taking blood-thinning medications. Early diagnosis helps distinguish it from other causes of acute abdominal pain and guides appropriate treatment.

Rectus sheath hematoma (RSH) is an uncommon but clinically significant condition that arises when blood accumulates within the rectus sheath, the fibrous compartment housing the rectus abdominis muscles.

This condition can often be confused with other abdominal pathologies, making accurate diagnosis vital for effective management.

What Are the Symptoms of Rectus Sheath Hematoma?

Recognizing the symptoms of rectus sheath hematoma is important because the condition can resemble other abdominal emergencies. Symptoms vary depending on the size of the hematoma and the amount of bleeding but often develop suddenly after injury, coughing, or strenuous activity.

Risk Factors for Rectus Sheath Hematoma

Several risk factors predispose individuals to the development of rectus sheath hematoma:

Age: Older adults are more susceptible due to frail vasculature and increased likelihood of anticoagulant use.
Gender: Females, particularly those who are pregnant, may be at higher risk due to physiological changes and increased abdominal pressure.
Coagulation Disorders: Conditions affecting blood clotting can lead to spontaneous hematoma formation.

Symptoms of Rectus Sheath Hematoma

Symptoms of rectus sheath hematoma can vary depending on the size and location of the hematoma:

Localized Pain: Patients often experience acute, sharp pain localized to the abdomen, exacerbated by movement or palpation.
Palpable Mass: A firm, tender mass may be palpable in the abdominal wall.
Ecchymosis: Bruising may be visible over the affected area, particularly in cases of extensive hematoma.

What Causes Rectus Sheath Hematoma?

Rectus sheath hematoma develops when bleeding occurs within the rectus sheath due to injury or rupture of the blood vessels supplying the abdominal wall. Understanding both the causes and the underlying mechanism helps determine the severity of the condition and the most appropriate treatment approach.

Causes of Rectus Sheath Hematoma

Rectus sheath hematoma can be induced by a variety of factors that disrupt the integrity of the epigastric vessels, which supply blood to the rectus abdominis muscles. Common causes include:

Trauma-related Hematoma: Direct trauma to the abdominal wall, such as from a fall, blunt impact, or surgical procedures, can lead to vessel rupture and hematoma formation.
Strain-related Injury: Activities that increase intra-abdominal pressure, such as heavy lifting or severe coughing, can cause strain-related injuries to the rectus sheath, resulting in hematoma.
Anticoagulation Therapy: Patients on anticoagulant or antiplatelet medications are at an increased risk due to impaired hemostasis, leading to spontaneous haemorrhage.

Pathophysiology of Rectus Sheath Hematoma

The pathophysiology of RSH involves the rupture of the superior or inferior epigastric arteries within the rectus sheath, causing blood to accumulate. Depending on the location of the rupture, hematomas may be classified into three types:

Type I: Small, confined hematomas that do not cross the midline or extend beyond the rectus sheath.
Type II: Larger hematomas that may cross the midline but remain confined within the rectus sheath.
Type III: Massive hematomas that extend into the peritoneal cavity, posing significant clinical challenges.

When Should You See a Doctor for Rectus Sheath Hematoma?

Medical evaluation is important if you develop sudden abdominal pain, swelling, or bruising, particularly after trauma, severe coughing, strenuous exercise, or while taking blood-thinning medications. Early diagnosis helps prevent complications and ensures prompt treatment before significant bleeding or other serious problems develop.

You should see a doctor if you have:

Persistent or worsening abdominal pain with localized swelling or tenderness.
A painful abdominal lump or increasing bruising after injury or physical strain.
New abdominal pain while taking anticoagulant or antiplatelet medications.

Get medical help immediately if:

Severe abdominal pain with dizziness, fainting, or rapid heartbeat.
Rapidly enlarging abdominal swelling or extensive bruising.
Signs of severe blood loss, such as confusion, low blood pressure, or difficulty staying awake.

Rectus sheath hematoma is commonly diagnosed and treated by general surgeons, emergency medicine specialists, vascular surgeons, and interventional radiologists, depending on the severity of the condition.

These could be signs of a serious complication of Rectus Sheath Hematoma that requires prompt medical care.

How is Rectus Sheath Hematoma Diagnosed?

Diagnosing rectus sheath hematoma involves a combination of clinical assessment and imaging studies to confirm the presence, size, and extent of bleeding. Early diagnosis is important because the condition can mimic other causes of acute abdominal pain and may require different treatment approaches.

Diagnosis of Rectus Sheath Hematoma

Accurate diagnosis of rectus sheath hematoma requires a combination of clinical evaluation and imaging studies:

Physical Examination: Detailed history and physical examination can help differentiate RSH from other abdominal conditions.
Ultrasonography: A non-invasive imaging modality that can detect fluid collections and assess hematoma size.
CT Scan: Computed tomography provides a detailed view of the hematoma and its extent, aiding in classification and management decisions.

Rectus Sheath Hematoma ICD-10 Code

In the International Classification of Diseases, Tenth Revision (ICD-10), rectus sheath hematoma is classified under the code S30.1, which denotes "Contusion of abdominal wall."

What is the Treatment for Rectus Sheath Hematoma?

Treatment for rectus sheath hematoma depends on the size of the hematoma, the severity of bleeding, the patient's symptoms, and overall health. While many cases improve with conservative care, larger or actively bleeding hematomas may require minimally invasive procedures or surgery.

Treatment Options for Rectus Sheath Hematoma

The management of rectus sheath hematoma is guided by the severity of symptoms and the type of hematoma:

Conservative Management: In cases of small, uncomplicated hematomas, conservative measures such as rest, analgesia, and cessation of anticoagulant therapy may suffice.
Interventional Radiology: For larger hematomas or those with active bleeding, interventional radiology techniques such as embolization may be employed to control hemorrhage.
Surgical Intervention: Rarely, surgical evacuation may be necessary for massive hematomas that do not respond to conservative or interventional measures.

Complications Associated with Rectus Sheath Hematoma

While many rectus sheath hematomas resolve without significant sequelae, complications can arise, particularly with type III hematomas:

Hemodynamic Instability: Massive bleeding can lead to shock, necessitating urgent resuscitation.
Infection: Hematomas may become infected, requiring antibiotic therapy or drainage.
Chronic Pain or Disability: Persistent pain or functional impairment may occur if the hematoma is not adequately managed.

How Can Rectus Sheath Hematoma Be Prevented?

Although not every case of rectus sheath hematoma can be prevented, reducing modifiable risk factors can lower the likelihood of developing the condition. Proper medication management, avoiding unnecessary abdominal strain, and seeking timely medical care for persistent coughing or injuries can help reduce the risk.

Take anticoagulant medications exactly as prescribed and attend regular monitoring appointments.
Avoid heavy lifting or strenuous activities if you have risk factors for bleeding.
Seek treatment for persistent coughing to reduce repeated abdominal strain.
Use proper lifting techniques to protect the abdominal muscles.
Follow your healthcare provider's advice after abdominal surgery or injury.

Frequently Asked Questions

1. What is rectus sheath hematoma?

A rectus sheath hematoma is a collection of blood within the sheath surrounding the rectus abdominis muscle, usually caused by bleeding from injured blood vessels or muscle tears.

2. What causes rectus sheath hematoma?

Common causes include abdominal trauma, severe coughing, heavy lifting, vigorous exercise, anticoagulant (blood-thinning) medications, abdominal surgery, and pregnancy.

3. What are the symptoms of rectus sheath hematoma?

Symptoms include sudden abdominal pain, localized swelling, bruising, a tender abdominal mass, abdominal wall stiffness, and, in severe cases, dizziness or low blood pressure due to blood loss.

4. How is rectus sheath hematoma diagnosed?

Diagnosis is based on a physical examination, blood tests, and imaging studies such as ultrasound or CT scan, with CT being the most accurate test.

5. What are the risk factors for rectus sheath hematoma?

Risk factors include older age, anticoagulant therapy, bleeding disorders, chronic coughing, pregnancy, obesity, recent abdominal surgery, trauma, and strenuous physical activity.

6. Is a rectus sheath hematoma serious?

It can be. Most cases are mild and resolve with treatment, but large hematomas may cause significant blood loss, anemia, or shock and require urgent medical attention.

7. How do you treat a rectus sheath hematoma?

Treatment depends on its severity and may include rest, pain relief, ice packs, stopping or adjusting blood-thinning medications, intravenous fluids or blood transfusions if needed, and, rarely, angiographic embolization or surgery for ongoing bleeding.

8. Is a hematoma a serious problem?

Most hematomas are minor and heal on their own. However, large or expanding hematomas, especially those causing severe pain, significant blood loss, or compression of nearby organs, require prompt medical evaluation.

9. What causes a rectus sheath abscess?

A rectus sheath abscess is different from a rectus sheath hematoma. It is caused by a bacterial infection within the rectus sheath, which may develop after abdominal surgery, trauma, spread of infection from nearby tissues, or infection of a pre-existing hematoma.
