Published on: September 5, 2011
Summary
This case study presents thoracopagus conjoined twins with unique visceral anomalies and complex cardiac defects. Surgical salvage of one twin might be hypothetically possible, while the other is sacrificed.
Area of Science:
- Medical Case Study
- Developmental Biology
- Congenital Anomalies
Background:
- Presents a rare case of thoracopagus conjoined twins.
- Highlights complex congenital anomalies in monozygotic twins.
Purpose of the Study:
- To document a unique case of conjoined twins with extensive visceral and cardiac malformations.
- To discuss potential surgical considerations in such complex cases.
Main Methods:
- Case report of a stillborn female thoracopagus conjoined twin pair.
- Detailed anatomical and pathological examination of shared and individual organs and circulatory systems.
Main Results:
- Twins shared pericardial and abdominal cavities, liver, and small bowel.
- Exhibited unique, non-mirror-image visceral anomalies, including asplenia in one twin.
- Presented severe, complex cardiac malformations with fused atria and ventricles, and intercirculatory communications.
- One twin had single atrium, solitary right ventricle, pulmonary atresia, and right aortic arch.
- The other twin had dual atrial septal defects, partial anomalous pulmonary venous connection, persistent left superior vena cava, solitary left ventricle, and left aortic arch.
Conclusions:
- Thoracopagus conjoined twins can present with highly individualized and complex visceral and cardiac anomalies.
- Surgical intervention for conjoined twins requires careful consideration of shared anatomy and individual viability.
- This case underscores the variability and complexity of congenital malformations in monozygotic twins.

01:17The Thoracic Cage: Sternum
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.

01:20The Thoracic Cage: Ribs
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...

01:15Thoracic Aorta
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
01:19Veins of Thorax
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

01:27Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:26Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
