Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

337
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Thoracic Aorta01:15

Thoracic Aorta

1.4K
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,...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

370
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Aneurysm I: Introduction01:30

Aneurysm I: Introduction

259
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

354
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.6K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Summary
This summary is machine-generated.

Split cord malformation (SCM) is a rare spinal condition where the spinal cord divides. Surgical removal of the dividing spur in a pediatric patient successfully corrected the malformation with an uneventful recovery.

Area of Science:

  • Neurology
  • Pediatric Neurosurgery
  • Developmental Biology

Background:

  • Split cord malformation (SCM) is a complex spinal dysraphism characterized by the longitudinal division of the spinal cord.
  • Pang's classification includes Type 1 (bony spur, separate dura), Type 2 (fibrous tissue, single dura), and Type 1.5 (dorsal/ventral bony spurs).
  • SCM can present with neurological deficits, often diagnosed in childhood.

Purpose of the Study:

  • To report a case of split cord malformation (SCM) in a pediatric patient.
  • To describe the diagnostic findings and surgical management of SCM.
  • To highlight the successful outcome following surgical intervention for SCM.

Main Methods:

  • A case study of a 2-year-old girl presenting with a dermal sinus and subsequent left foot dorsiflexion weakness.
  • Magnetic Resonance Imaging (MRI) of the spine was utilized for diagnosis.
  • Surgical excision of the spinal cord spur was performed.

Main Results:

  • MRI revealed a posteriorly arising spur with a partial bony and fibrous band dividing the spinal cord within separate dural coverings.
  • Surgical removal of the spur successfully unified the dural covering.
  • The patient experienced an uneventful postoperative recovery.

Conclusions:

  • This case demonstrates a variant of split cord malformation (SCM) requiring surgical intervention.
  • Complete surgical removal of the spur is an effective treatment for SCM.
  • Early diagnosis and surgical management can lead to positive outcomes in pediatric SCM cases.
