Insights

Umbilical cord stricture, a common abnormality, can lead to intrauterine fetal demise (IUFD). This case highlights a fetus with stricture and entanglement, emphasizing the need for further research and surveillance in future pregnancies.

Area of Science:

  • Perinatology
  • Obstetrics
  • Fetal Medicine

Background:

  • Umbilical cord abnormalities, particularly stricture, are linked to intrauterine fetal demise (IUFD).
  • Cord entanglement, while less commonly fatal, is associated with fetal growth restriction and other morbidities.

Observation:

  • A 27-year-old woman presented with decreased fetal activity at 34 weeks gestation.
  • Ultrasonography confirmed no fetal heart activity or blood flow.
  • A demised fetus with umbilical cord stricture and abdominal entanglement was delivered.

Findings:

  • The fetus weighed 1,830g, below the tenth percentile for gestational age.
  • Both umbilical cord stricture and entanglement can impede fetal development.
  • Umbilical cord stricture may have played a significant role in this IUFD case.

Implications:

  • The etiology and sequence of events in this case remain unclear.
  • Further research, including autopsy, is needed to understand these cord abnormalities.
  • Patients with prior IUFD due to cord stricture require genetic counseling and close fetal surveillance in subsequent pregnancies due to recurrence risk.

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
