Insights

Postoperative portal and splenic vein thrombosis (PSVT) is a rare complication after abdominal surgery. Clinicians should consider PSVT after splenectomy for splenomegaly or total colectomy for ulcerative colitis.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Pediatric Surgery

Background:

  • Postoperative portal and splenic vein thrombosis (PSVT) is a rare but serious complication following abdominal surgery.
  • Early diagnosis and management are crucial for patient outcomes.

Observation:

  • Two infant cases of PSVT are presented.
  • One infant developed PSVT after splenectomy for massive splenomegaly.
  • The second infant developed PSVT after a total colectomy for ulcerative colitis.

Findings:

  • The literature review indicates a potential association between PSVT and specific surgical procedures.
  • Splenectomy for significant splenomegaly and total colectomy for ulcerative colitis are identified as risk factors.

Implications:

  • This study highlights the importance of considering PSVT in infants presenting with abdominal symptoms post-surgery.
  • Enhanced vigilance and diagnostic workup are recommended for at-risk patient populations.
  • Further research may elucidate the precise mechanisms and optimal preventative strategies for PSVT.

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.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...
Portal Hypertension01:22

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...

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
