Veins of Thorax01:19

Veins of Thorax

2.3K
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.

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

2.0K
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Overview of Systemic Arteries

2.3K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Lymphatic Vessels and Lymph Transport01:16

Lymphatic Vessels and Lymph Transport

24.0K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

Veins of Lower Limbs01:15

Veins of Lower Limbs

2.8K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Summary
This summary is machine-generated.

Persistent left superior vena cava (PLSVC), a common heart anomaly, can be linked to airway and GI issues. Detailed fetal scans are crucial for identifying these extra-cardiac anomalies alongside PLSVC diagnosis.

Area of Science:

  • Cardiology
  • Fetal Medicine
  • Pediatric Surgery

Background:

  • Persistent left superior vena cava (PLSVC) is a frequent congenital cardiac anomaly.
  • Diagnosis typically involves fetal echocardiography.
  • Associated extra-cardiac anomalies, particularly of the upper airway and gastrointestinal tract, are less commonly recognized.

Observation:

  • A preterm infant presented with a rare triad of congenital anomalies.
  • The infant exhibited PLSVC, laryngeal atresia, and esophageal atresia.

Findings:

  • This case underscores the importance of comprehensive fetal assessment beyond echocardiography.
  • Detailed evaluation for extra-cardiac anomalies is vital in fetuses diagnosed with PLSVC.

Implications:

  • Early identification of associated anomalies can guide timely intervention.
  • Highlights the need for integrated care in managing complex congenital conditions.
  • Emphasizes thorough prenatal screening for improved neonatal outcomes.
