Mycotic Aneurysm following a Dog Bite: The Value of the Clinical History and Molecular Diagnostics

Annals of Vascular Surgery

Abstract

A 63-year-old Caucasian taxi driver presented with a 3-week history of malaise, night sweats, 7 kg weight loss, generalized arthralgia, and persistent mid-lower abdominal pain. Blood inflammatory markers were raised, and a computed tomography scan demonstrated an irregular degeneration of the infrarenal aorta, with a differential diagnosis including aortic infection. An urgent type IV thoracoabdominal aneurysm repair was performed with a rifampicin-soaked aortic tube graft during an open procedure. No organisms were grown from multiple peripheral blood cultures or culture of the affected aorta. However, subsequent 16S ribosomal polymerase chain reaction analysis of the resected aorta identified Capnocytophaga canimorsus as the causative organism-a commensal that lives in the mouth of dogs and cats. The patient subsequently gave a history of multiple bites from his pet dog over recent months-the likely source of infection. He was treated with 8 weeks of intravenous antibiotics before switching to oral antibiotics for an additional 6 weeks.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
