ICD-10: S35.349

The ICD-10 code S35.349 refers to an unspecified injury of the inferior mesenteric vein. This code falls under the broader category of injuries to the blood vessels of the abdomen, specifically those affecting the mesenteric veins, which are crucial for draining blood from the intestines.

Clinical Description

Definition

An injury to the inferior mesenteric vein can occur due to various traumatic events, including blunt or penetrating trauma, surgical complications, or as a result of underlying medical conditions that may compromise vascular integrity. The inferior mesenteric vein is responsible for draining blood from the distal colon and rectum, and any injury to this vein can lead to significant clinical consequences.

Symptoms

Patients with an injury to the inferior mesenteric vein may present with a range of symptoms, including:
- Abdominal pain: This can vary in intensity and may be localized or diffuse, depending on the extent of the injury.
- Hemorrhage: Internal bleeding may occur, leading to signs of hypovolemia such as dizziness, weakness, or shock.
- Signs of peritonitis: If the injury leads to contamination of the peritoneal cavity, symptoms may include fever, rigidity of the abdomen, and rebound tenderness.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies. Common diagnostic approaches include:
- CT Scan: A computed tomography scan of the abdomen can help visualize vascular injuries and assess for associated complications such as hematomas or organ damage.
- Ultrasound: This may be used in certain cases to evaluate blood flow and detect any abnormalities in the mesenteric vessels.
- Angiography: In some instances, angiography may be performed to assess the vascular status and identify any occlusions or injuries.

Treatment

Management of an injury to the inferior mesenteric vein depends on the severity and nature of the injury:
- Conservative management: In cases of minor injuries without significant bleeding, observation and supportive care may be sufficient.
- Surgical intervention: More severe injuries may require surgical repair of the vein or resection of affected bowel segments if there is associated ischemia or necrosis.
