|May 8, 2026
Summary
Acquired gastrointestinal fistulas, especially those involving the cardiovascular system, pose serious risks. This study highlights three deaths from postsurgical fistulas, emphasizing careful autopsy documentation for unexpected deaths.
Area of Science:
- Forensic pathology
- Gastroenterology
- Cardiovascular surgery
Background:
- Gastrointestinal (GI) fistulas are rare, occurring congenitally or acquired.
- Acquired GI fistulas connecting to the cardiovascular system present significant morbidity and mortality risks.
Purpose of the Study:
- To report on three fatalities linked to acquired, postsurgical fistulas between the GI and cardiovascular systems.
- To underscore the importance of thorough autopsy documentation in cases of sudden death with relevant surgical or bleeding histories.
Main Methods:
- Case series review of three autopsy cases.
- Detailed dissection and documentation of post-surgical fistula formation.
Main Results:
- Three deaths were directly attributed to acquired, postsurgical fistulas involving both GI and cardiovascular systems.
- These cases underscore the potential for lethal complications from such fistulas.
Conclusions:
- Medical examiners should maintain a high index of suspicion for GI-cardiovascular fistulas in specific autopsy cases.
- Thorough dissection and documentation are crucial for identifying these rare but fatal complications.

01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
01:24Esophageal 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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:22Portal 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...
