Insights

Persistent left superior vena cava (PLSVC) affects 6.1% of pediatric patients with congenital heart defects. Angiography is crucial for diagnosing PLSVC and associated anomalies to prevent surgical complications.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Medical Imaging

Background:

  • Persistent left superior vena cava (PLSVC) is a congenital anomaly.
  • Its prevalence in patients with congenital heart defects (CHDs) requires assessment.
  • Identifying associated cardiac anomalies is crucial for management.

Purpose of the Study:

  • To determine the prevalence of PLSVC in children with CHDs.
  • To identify congenital heart anomalies commonly accompanying PLSVC.

Main Methods:

  • Retrospective review of 1205 children undergoing cardiac catheterization (2000-2007).
  • Superior vena cava (SVC) injection via angiography used to detect PLSVC.
  • Comparison of PLSVC detection rates between echocardiography and angiography.

Main Results:

  • PLSVC prevalence was 6.1% overall; angiography detected it in 74 children (6.1%), while echocardiography identified it in 32 (2.6%).
  • Commonly associated anomalies included ventricular septal defect (56.8%), atrial septal defect (41.9%), and pulmonary stenosis (25.7%).
  • A communication between right and left SVC was found in 27% of PLSVC cases.

Conclusions:

  • Angiography with SVC injection is vital for diagnosing PLSVC and associated anomalies in CHD patients.
  • Early diagnosis of PLSVC can help prevent surgical morbidity and mortality.
  • Echocardiography may show a dilated coronary sinus in PLSVC cases.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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 middle...
Veins of Thorax01:19

Veins 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.
The...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Veins of the Abdomen and Pelvis

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...
