Thoracic Aorta01:15

Thoracic Aorta

511
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,...

Spinal Nerves: Plexus I

963
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

21
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...

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

638
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Pleural Disorders: Types and Brief Description

The pleura is a vital part of the respiratory system. It's a double-layered membrane surrounding the lungs and lining the chest cavity. The two layers of the pleura are:

Pleural Effusion I: Introduction01:25

Pleural Effusion I: Introduction

1.1K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's...

Summary

Morel-Lavallée lesions (MLLs) can occur in the cervico-thoracic region after trauma. Conservative management with a spinal brace proved effective for this rare MLL presentation.

Area of Science:

  • Orthopedics
  • Trauma Surgery
  • Radiology

Background:

  • Morel-Lavallée lesions (MLLs) are post-traumatic fluid collections typically found in the gluteal or thigh regions.
  • These lesions result from shearing forces separating the subcutaneous tissue from the underlying fascia.
  • Existing literature predominantly focuses on MLLs in the lower body, leaving atypical locations under-documented.

Observation:

  • A case is presented of a woman in her 40s with a cervico-thoracic fluctuant collection following trauma.
  • Imaging confirmed the diagnosis as a Morel-Lavallée lesion.
  • This represents the first documented instance of an MLL in the cervico-thoracic region.

Findings:

  • An orthoplastic approach was employed, leading to non-operative management utilizing a spinal brace.
  • The cervico-thoracic MLL demonstrated complete resolution within three months of the initial injury.
  • The patient remained symptom-free at the final follow-up appointment.

Implications:

  • This case expands the known anatomical distribution of Morel-Lavallée lesions beyond the typical pelvic and thigh areas.
  • It highlights the potential efficacy of conservative management, including bracing, for atypical MLLs in challenging locations.
  • Further research into the diagnosis and management of MLLs in unusual anatomical sites is warranted.
