Summary
Warm autoimmune hemolytic anemia (AIHA) is a rare condition. Splenic vein ligation worsened AIHA in a patient, highlighting the spleen's role in red blood cell destruction.
Area of Science:
- Hematology
- Immunology
- Surgical Oncology
Background:
- Warm autoimmune hemolytic anemia (AIHA) involves IgG autoantibodies causing red blood cell destruction, primarily in the spleen.
- Hypersplenism is known to exacerbate red blood cell destruction in AIHA patients.
Observation:
- A patient with undiagnosed warm AIHA underwent splenic vein ligation during pancreaticoduodenectomy for a neuroendocrine tumor.
- Following the procedure, the patient experienced a significant increase in hemolysis.
Findings:
- The case demonstrates a direct correlation between splenic vein ligation and exacerbated hemolysis in a patient with previously unrecognized warm AIHA.
- This suggests that altered splenic hemodynamics can significantly impact red blood cell survival in AIHA.
Implications:
- This case underscores the importance of considering AIHA in patients presenting with unexplained hemolysis, especially before procedures affecting splenic function.
- It highlights the spleen's critical role in the pathophysiology of warm AIHA and the potential complications of interventions that alter splenic blood flow.

Esophageal Varices-I: Introduction
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...
Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
Hepatic Portal System
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
