History And Clinical Findings:
A 77-year-old woman was admitted to a nearby hospital because of acute upper gastrointestinal bleeding and collapse. A Greenfield caval filter had been implanted nine years before admission because of pulmonary embolism.
Investigations:
Gastroduodenoscopy showed two hooks of the caval filter having penetrated the duodenum. The diagnosis was confirmed by an abdominal CT scan.
Treatment And Course:
The patient was transferred to our hospital for surgical removal of the cava filter, which was done through the right-flank retroperitoneal approach. She had an uneventful recovery and was discharged from the hospital on the 7th postoperative day.
Conclusions:
Acute upper gastrointestinal bleeding caused by by a Greenfield cava filter perforating the duodenum is an extremely rare complication. But in case of acute gastrointestinal bleeding in a patient with an implanted caval filter or vascular prosthesis this should be considered and the filter removed surgically.

Inflammatory Bowel Disease I: Ulcerative Colitis
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...
