Abdominal Aorta01:25

Abdominal Aorta

1.2K
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Inflammatory Bowel Disease I: Ulcerative Colitis

321
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

2.3K
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

Appendicitis-II: Diagnostic Studies and Management

145
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...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

333
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

620
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

    Resumen

    Una rara arteria cólica izquierda duplicada causó sangrado gastrointestinal inferior severo (LGIB) en un paciente. El tratamiento exitoso implicó la embolización de la bobina superselectiva de este vaso aberrante, destacando la importancia de reconocer las variantes vasculares raras.

    Área de la Ciencia:

    • Cirugía vascular
    • Gastroenterología
    • Radiología

    Sus antecedentes:

    • Un hombre de 72 años presentado con sangrado gastrointestinal inferior grave (LGIB) e inestabilidad hemodinámica.
    • El diagnóstico inicial no pudo identificar la fuente de la hemorragia, requiriendo más investigación.

    Objetivo del estudio:

    • Para reportar un caso raro de LGIB causado por una arteria cólica izquierda duplicada.
    • Hacer hincapié en los desafíos diagnósticos y terapéuticos planteados por anomalías vasculares raras en LGIB.

    Principales métodos:

    • La reevaluación de la tomografía computarizada (TC) identificó una arteria cólica izquierda duplicada originada en la aorta.
    • La angiografía señaló la arteria aberrante como la fuente de la hemorragia diverticular.
    • Se realizó una embolización superselectiva para tratar la fuente de la hemorragia.

    Principales resultados:

    • La arteria cólica izquierda duplicada fue identificada con éxito como la fuente de la hemorragia diverticular.
    • La embolización de la bobina superselectiva controlaba efectivamente la hemorragia.
    • El paciente mostró una buena recuperación sin sangrado recurrente a los 6 meses de seguimiento.

    Conclusiones:

    • La LGIB aguda es un desafío clínico significativo con diversas causas.
    • Las variaciones anatómicas raras, como las arterias cólicas duplicadas, pueden complicar el diagnóstico y el tratamiento de la LGIB.
    • El reconocimiento de anomalías vasculares poco comunes es crucial para el éxito del tratamiento y la mejora de los resultados del paciente en LGIB.
