Insights

Bilateral superior vena cavae (SVCs) increase the risk of interrupted inferior vena cava (IIVC) in single-ventricle patients. Identifying IIVC is crucial for managing children undergoing bilateral cavopulmonary anastomoses (CPAs).

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Surgery
  • Vascular Surgery

Background:

  • Bilateral superior vena cavae (SVCs) present surgical challenges in single-ventricle palliation.
  • Bilateral SVCs have been associated with poorer outcomes in pediatric cardiac surgery.

Purpose of the Study:

  • To investigate the association between bilateral SVCs and interrupted inferior vena cava (IIVC).
  • To evaluate the outcomes of children with bilateral SVCs undergoing bilateral cavopulmonary anastomoses (CPAs).

Main Methods:

  • Retrospective review of 40 children who underwent bilateral CPAs.
  • Analysis of patient demographics, cardiac morphology, and presence of IIVC.

Main Results:

  • Interrupted inferior vena cava (IIVC) was identified in 8 of 40 patients.
  • All IIVC cases were associated with a hypoplastic right ventricle.
  • Bilateral SVCs were more frequently associated with IIVC compared to single SVC.

Conclusions:

  • Bilateral SVCs in single-ventricle anatomy are often linked to IIVC.
  • Patients with bilateral CPAs and IIVC experience a challenging postoperative period.
  • Screening for IIVC is recommended in patients with bilateral SVCs prior to or during surgical planning.

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...

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.

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...

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...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
Portal Hypertension01:22

Portal Hypertension

Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
