Case Reports in Vascular Medicine
|July 9, 2021
Summary
Persistent left superior vena cava (PLSVC) is a rare thoracic anomaly. This case highlights its association with asthma, emphasizing the need for thorough cardiac evaluation.
Area of Science:
- Cardiovascular Medicine
- Thoracic Surgery
- Medical Imaging
Background:
- Persistent left superior vena cava (PLSVC) is an uncommon congenital anomaly of the thoracic venous system.
- This case report details an 18-year-old male diagnosed with isolated PLSVC.
Observation:
- The patient presented with dyspnea and asthma symptoms.
- Diagnostic imaging revealed cardiomegaly, mediastinal widening, and confirmed PLSVC.
- Echocardiography and CT scans identified cardiac chamber ectasias and a double superior vena cava.
Findings:
- The patient had an asymptomatic PLSVC incidentally discovered due to asthma.
- Respiratory functional tests confirmed associated asthma, which improved with treatment.
Implications:
- PLSVC, though rare, can have significant clinical relevance.
- Systematic screening for associated severe cardiac malformations is crucial in patients with PLSVC.

1.4K
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.

3.4K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

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...

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.
