Clinical presentation of incomplete uterine rupture
The clinical manifestations of the pathology directly depend on the volume of blood loss.
- Hemodynamic disorders: pallor of the skin, tachycardia, and hypotension.
- Pain syndrome: patients complain of pain in the sacral region and lower abdomen, which may radiate to the leg.
- Postpartum features: the uterus is displaced to the side opposite to the rupture. A mass without clear contours and borders, corresponding to the developing hematoma, is palpated laterally to it.
It is worth noting that the clinical picture may develop in the late postpartum period. Additionally, diffuse abdominal tenderness, progressive flatulence, and intestinal paresis are observed.
Diagnosis of hematomas and ruptures
If the clinical picture is pronounced, making a diagnosis is not difficult. However, diagnostic difficulties arise specifically in cases of incomplete uterine ruptures.
The leading symptoms are arterial hypotension (sometimes short-lived) and other manifestations of hemorrhagic shock.
The primary instrumental method in the postpartum period is manual exploration of the uterus, which allows for the detection of a uterine wall defect.
Difficulties and errors: myometrial contraction can mask the rupture. In addition, the interligamentous space, filled with blood clots, is sometimes mistakenly taken for the uterine cavity by inexperienced physicians. Ultrasound and laparoscopy are used to precisely clarify the diagnosis.
Differential diagnosis
During pregnancy, a threatening histopathic uterine rupture requires differential diagnosis with acute surgical conditions:
- Acute appendicitis: has similar symptoms (nausea, vomiting, abdominal or epigastric pain, more often on the right). An important clinical rule: if a pregnant woman has a uterine scar and shows signs of acute appendicitis, scar dehiscence should be suspected first.
- Renal colic: an erroneous diagnosis may occur if the patient has a scar on the posterior uterine wall (e.g., after myomectomy).
Briefly: answers to topical questions
What is the surgical treatment algorithm for an expanding obstetric vaginal hematoma?
The surgical treatment algorithm depends on the size of the lesion and the effectiveness of hemostasis.
- Significant hematomas (diameter >3 cm) — incision, evacuation, and ligation of bleeding vessels are indicated (or burying sutures if ligation is impossible).
- Very large hematomas — after suturing, a drainage tube is additionally placed in the cavity for 2–3 days.
- Ongoing bleeding (ineffectiveness of surgical methods) — MR angiography is performed for subsequent selective endovascular embolization of vessels.
What local symptoms and specific complaints are characteristic directly of vulvar and vaginal hematomas?
Vaginal hematomas are characterized by specific subjective sensations and visual tissue changes.
- Complaints — a sensation of fullness or pressure during hematoma formation.
- Objective picture — upon examination, the hematoma is visualized as a bluish, tense-elastic mass.
- In case of vaginal trauma, external bleeding from the vaginal wall is also possible.
Uterine scar + pain on the right = think about scar dehiscence, not appendicitis!
Class and exam questions
What symptoms indicate internal bleeding in incomplete uterine rupture?
The main symptoms include skin pallor, tachycardia, hypotension, as well as pain in the lower abdomen and sacrum radiating to the leg.
What difficulties arise during manual exploration of the uterus in the postpartum period?
Myometrial contraction can mask the rupture, and the interligamentous space filled with clots is sometimes mistakenly taken for the uterine cavity.
With which pathologies is threatening histopathic uterine rupture in pregnant women differentiated?
Differential diagnosis is performed with acute appendicitis and renal colic, especially if the patient has a uterine scar.
