Ultrasonography01:17

Ultrasonography

8.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Endoscopic Studies II: Thoracocentesis

1.9K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Ultrasound I: Abdominal Ultrasonography

2.5K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Area of Science:

  • Cardiology
  • Medical Devices
  • Diagnostic Imaging

Background:

  • Cardiac perforation is a rare but serious complication of pacemaker implantation.
  • Right ventricular lead perforation can lead to significant intrathoracic bleeding, such as hemothorax.

Purpose of the Study:

  • To report a rare case of cardiac perforation and hemothorax following pacemaker implantation.
  • To emphasize the diagnostic utility of Point-of-Care Ultrasound (POCUS) in such critical scenarios.

Main Methods:

  • A case study describing a patient with pacemaker implantation.
  • Diagnosis was aided by Point-of-Care Ultrasound (POCUS) to identify lead migration and hemothorax.
  • Treatment involved emergent percutaneous drainage, device removal, and replacement.

Main Results:

  • Successful diagnosis of right ventricular lead perforation and massive left-sided hemothorax using POCUS.
  • Effective emergent management through percutaneous drainage and device revision.

Conclusions:

  • Point-of-Care Ultrasound (POCUS) is a valuable tool for rapid diagnosis of pacemaker-related complications.
  • Prompt intervention including drainage and device management is crucial for patient outcomes.
