The term “ectopic pregnancy” is often used to refer to a pregnancy in the fallopian tubes, but this is not entirely accurate. Today, the more correct term is “ectopic pregnancy.” An ectopic pregnancy is any pregnancy that is located outside the uterine cavity (in the tube, cervix, scar from a cesarean section, ovary, or abdominal cavity). This is a relatively rare phenomenon, occurring in 2-3% of cases. However, due to difficulties in diagnosis and the potential for serious complications, it can lead to life-threatening consequences.
Under normal circumstances, fertilization of the egg occurs in one of the fallopian tubes. The fertilized egg then travels down into the uterine cavity, where it implants. When this process is disrupted, implantation can occur in the fallopian tube (in over 90% of cases), ovary (1-3%), cervix (1%), scar from a cesarean section (1-3%), or abdominal cavity (1%).
An ectopic pregnancy cannot develop normally as it would in the uterine cavity, and therefore requires termination. Depending on the location of the pregnancy, HCG levels, ultrasound findings, and the patient’s condition, different treatment options may be recommended: expectant management, medical treatment, surgical intervention, or a combination of these. In practice, the majority of ectopic pregnancies are treated surgically, but under certain conditions, conservative treatment can also be successful.
If an ectopic pregnancy goes undetected, the progressive growth of the gestational sac and embryo may lead to rupture at the site of implantation, causing massive blood loss, which is life-threatening for the woman.
Causes of Ectopic Pregnancy
The primary causes are disruptions in the free movement of the fertilized egg into the uterine cavity due to tubal obstruction or increased activity of the blastocyst’s outer membrane.
Risk Factors for Ectopic Pregnancy:
- Adhesions in the fallopian tubes or abdominal cavity
- Sexually transmitted infections
- Tumors in the pelvic area
- Endometriosis
- Hormonal imbalances
- History of abortions
- Presence of an intrauterine device (IUD)
- In vitro fertilization (IVF)
- Harmful habits, among others
Therefore, it is crucial for a woman, when planning a pregnancy, to undergo an examination by a gynecologist and treat any identified conditions if necessary. It’s important to remember that some conditions may be asymptomatic and not cause any complaints.
Ectopic Pregnancy: Symptoms and Early Signs
In the early stages, an ectopic pregnancy usually progresses without any pathological signs. Women typically experience natural symptoms like a missed period, nausea and vomiting, breast tenderness, and similar signs. Symptoms that may cause concern usually appear around 4-5 weeks.
The warning signs include:
- Lower abdominal pain (persistent dull, periodic sharp, or cramping)
- Pain during urination and bowel movements
- Pain in the rectal area
- A sensation of abdominal bloating
- Vaginal spotting or bleeding (ranging from light to heavy, pale pink to bright red or dark brown, sometimes with clots)
- Severe nausea and constant vomiting
- Dizziness and general weakness
Loss of consciousness, pale skin, tachycardia (heart rate >100 bpm), hypotension (<90/60 mmHg), bleeding, and acute pain can indicate a ruptured ectopic pregnancy and significant blood loss, requiring immediate hospitalization.
Depending on the location and size of the gestational sac, symptoms can vary in severity. In many cases, women do not notice these signs until a fallopian tube ruptures or other complications arise, at which point the condition can rapidly worsen and urgent medical care is necessary.
Complications of Ectopic Pregnancy
Without timely diagnosis and treatment, ectopic pregnancy can lead to:
- Rupture of the organ where the implantation of the fertilized egg occurred
- Bleeding into the abdominal cavity
- Massive blood loss
- Death of the woman
In the case of a ruptured ectopic pregnancy, emergency surgery is required to save the woman’s life. However, even with the best outcome, the fallopian tube or another affected organ may need to be partially or completely removed. This can result in future difficulties with conception, an increased risk of recurrent ectopic pregnancy, or infertility.
Diagnosis of Ectopic Pregnancy
Diagnosing this condition can only be done through a comprehensive examination. A woman should consult an obstetrician-gynecologist or a reproductive specialist, especially if she has undergone an IVF program. The specialist will perform an examination, review her medical history, and prescribe additional tests.
Diagnostic methods for ectopic pregnancy:
- Transvaginal ultrasound of the pelvic organs
- Blood test for human chorionic gonadotropin (HCG)
- MRI of the pelvic organs
In most cases, a transvaginal ultrasound of the pelvic organs and an HCG blood test, which starts increasing from the 6th-8th day after conception, are sufficient to make the diagnosis.
During the ultrasound, the doctor first checks for the presence of a gestational sac in the uterine cavity. If it is absent, they carefully examine other pelvic organs and spaces.
Measuring HCG levels in the blood helps confirm the diagnosis. In a normal pregnancy, HCG levels double every 48 hours, while in ectopic pregnancy, the HCG increase may be slower. However, it is important to remember that a single HCG measurement cannot alone predict ectopic pregnancy.
How is Ectopic Pregnancy Treated
Ectopic pregnancy is treated using two main approaches:
- Conservative management
- Surgical intervention
Features of Conservative Treatment
Medication treatment for ectopic pregnancy is most commonly used for tubal pregnancy and, in some cases, can be as successful as laparoscopic surgery. This method is also occasionally effective for cervical pregnancy. The mandatory conditions for conservative treatment include:
- Low HCG levels (ideally below 1500 IU/L, although levels up to 5000 IU/L may be considered, but with a lower success rate)
- The patient’s hemodynamic stability
- Small size of the gestational sac
- Absence of fetal cardiac activity
- Full certainty that there is no intrauterine pregnancy
- No contraindications to the prescribed medication
The patient is given a medication that inhibits the growth of the trophoblast and prevents cell division. To monitor the treatment’s progress, the patient’s HCG levels are checked regularly, and repeat ultrasounds of the pelvic organs are performed.
The advantage of conservative therapy is that it is non-invasive and, if successful, preserves the woman’s reproductive functions. However, it is important to consider the risks: there is a chance that the gestational sac may not be completely expelled or that the fallopian tube may rupture, leading to internal bleeding, in which case surgery may still be required.
Surgical Treatment of Ectopic Pregnancy
The method and extent of surgical intervention depend on the gestational age, the size and location of the gestational sac, and the presence or absence of complications. The patient may be recommended one of the following:
- Laparoscopic surgery – a minimally invasive technique that accesses the abdominal cavity through three small incisions in the abdominal wall.
- Laparotomy surgery – an open surgery, typically performed when complications have developed.
In most cases, when ectopic pregnancy is diagnosed early, laparoscopic surgery is performed. This approach is the least traumatic, reduces hospitalization to 1-2 days, and shortens the recovery period to just a few weeks.
During the procedure, surgeons make three small incisions on the abdominal wall, each up to 1 cm in diameter, and insert endoscopic equipment into the abdominal cavity. This allows them to inspect and remove the gestational sac. If possible, surgeons aim to preserve the fallopian tube or ovary. In the case of complications, organ removal may be required.
The primary goals of surgery for ectopic pregnancy are to save the woman’s life and to preserve her ability to conceive and bear children in the future.
What to Do If Ectopic Pregnancy Occurs
Timely diagnosis and treatment are crucial in the case of an ectopic pregnancy. At the first signs, you should immediately consult an obstetrician-gynecologist and undergo the necessary examination. If the doctor recommends surgery, do not refuse or delay it. The earlier the treatment is administered, the higher the chances of successfully conceiving and giving birth to a child in the future.
In Kyiv, you can undergo expert-level diagnosis and treatment of ectopic pregnancy at the ICSI Clinic‘s reproductive medicine center. The clinic is equipped with a high-tech surgical facility, and experienced surgeons with many years of practice are available.
