Mycotic aneurysms are aneurysms infected by bacteria or fungi. These may be secondary to an endocarditis, or they may be primary, and then are developed from a septicemia or bacteremia. The diagnosis, often difficult, is sometime only made during complications, the most severe of which is rupture. This diagnosis must be aided by new imaging techniques such as ultrasonography, tomodensitometry, magnetic resonance imaging. The treatment is medical (antibiotics) and surgical.

Thoracic aortic pseudoaneurysms are a rare but serious complication of infectious processes, often resulting from mycotic (infectious) aneurysms, occurring when the vessel wall is compromised by an infection, leading to the formation of a pseudoaneurysm [1]. Mycotic aneurysms typically result from bacteremia or fungemia, with common sources being infective endocarditis or other systemic infections. Tuberculosis, though a common infectious disease worldwide, is an unusual cause of aortic pseudoaneurysm formation.

Article Synopsis
- Arteriovenous (AV) fistulas are crucial for hemodialysis in chronic kidney disease patients, but complications like thrombosis and rupture often necessitate surgical takedown.
- A study of 29 patients revealed that the majority underwent AV fistula takedown due to rupture, with a focus on maintaining arterial continuity when possible.
- Proper education on fistula care and early detection of issues can significantly improve patient outcomes and reduce the risks of serious complications.
Trans-arterial omental flap protection for infected femoral artery aneurysm in a patient with Parkes-Weber syndrome.

We report a case of a 75-year-old man diagnosed with Parkes-Weber syndrome with an infected common femoral artery aneurysm secondary to chronic venous ulcers and groin infection. Given the symptomatic and rapid enlargement of the aneurysm, emergency aneurysmectomy and crossover femoro-femoral bypass were performed with an omental flap routed intraluminally through the aneurysm of the ipsilateral external iliac artery. The transarterial route enabled the short-cutting of the omental flap and the potential prevention of infection in the adjacent external iliac artery.

Mycotic aneurysms are rare but severe complications that can arise from systemic bacterial infections, including those caused by Salmonella species. These aneurysms can progress rapidly and are associated with high mortality. A 62-year-old man with poorly controlled type 2 diabetes mellitus presented to the hospital in septic shock.

BACKGROUND The bacterial organism Capnocytophaga canimorsus is an oral commensal of cats and dogs and can cause life-threatening infections like mycotic aneurysm, meningitis, and sepsis. Mycotic aneurysms occur when microbial infections cause arterial wall degeneration. Difficulty in diagnosing Capnocytophaga canimorsus infection can occur due to the bacteria's fastidious nature and laboratory testing limitations, contributing to the infection's high morbidity and mortality.
