Acute Pancreatitis II: Clinical Manifestations and Management01:30

Acute Pancreatitis II: Clinical Manifestations and Management

187
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Acute Coronary Syndrome I: Introduction

92
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Acute Coronary Syndrome III: Diagnostic Studies

28
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

58
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Area of Science:

  • Radiology
  • Gastroenterology
  • Emergency Medicine

Background:

  • Acute mesenteric ischemia (AMI) is a rare but life-threatening condition presenting as acute abdomen.
  • Computed tomography (CT) is essential for diagnosis, particularly biphasic protocols.
  • Early diagnosis is vital to prevent bowel necrosis.

Purpose of the Study:

  • To review the role of CT imaging in diagnosing AMI.
  • To highlight key CT findings, including vascular and non-vascular signs.
  • To emphasize the importance of CT in managing AMI, especially in small bowel obstruction (SBO).

Main Methods:

  • Review of CT imaging techniques for AMI.
  • Discussion of biphasic CT with CT angiography.
  • Analysis of specific CT findings: bowel wall hypoenhancement, pneumatosis intestinalis, portomesenteric venous gas, free air, and organ infarcts.

Main Results:

  • Biphasic CT with CT angiography is mandatory for assessing arterial, venous, and non-occlusive mesenteric ischemia (NOMI).
  • Specific CT findings like bowel wall hypoenhancement, pneumatosis intestinalis, and portomesenteric venous gas are highly indicative of AMI.
  • Non-specific findings include bowel wall thickening, mesenteric stranding, and ascites.

Conclusions:

  • Familiarity with CT imaging features of AMI is vital for early diagnosis.
  • Optimized CT protocols enhance iodine conspicuity for accurate assessment of bowel enhancement.
  • Accurate CT interpretation aids in treatment planning and reduces misdiagnosis in AMI and SBO.
