Brucellosis is a multisystem zoonotic disease. Mycotic aneurysm due to
Brucella
is rare and has no clear management approach. Here, we present two cases of mycotic aortic aneurysm due to
Brucella
. The first patient was treated with surgical resection of a symptomatic infrarenal abdominal aortic aneurysm combined with lifelong doxycycline and rifampicin. The second patient improved with conservative treatment including a 6-month course of antibiotics and regular clinical and radiologic monitoring. Through these cases, we hope to draw attention to this serious adverse effect of
Brucella
and the importance of management of its local arterial complications, especially in endemic areas.
Aneurysms of the foot arteries are uncommon but can lead to devastating complications such as acute foot ischemia or arterial rupture if left untreated. In this case series, we present four cases of aneurysms of the foot: one true dorsalis pedis artery aneurysm and three cases of post-traumatic plantar artery pseudoaneurysms with arteriovenous fistulas. All four patients were successfully managed with surgical excision of the aneurysm with or without arteriovenous fistulas ligation. Our case series is followed by discussion on the etiology, clinical presentation and management strategy of patients with aneurysms of the foot arteries.
Subclavian and upper extremity venous pseudoaneurysms are rare and poorly understood. We present the case of a 45-year-old woman with a right subclavian vein pseudoaneurysm that formed after blunt trauma to the upper chest and shoulder. The patient was managed successfully with surgical excision through a supraclavicular approach. The case report is followed by a discussion on the etiology, clinical presentation, and management of venous pseudoaneurysms.
Background Endovascular stent grafting has emerged as an option to treat traumatic aorta injuries with reported significantly low mortality and morbidity. Stent collapse is one of the complications that can occur in this type of treatment. The aim of this article is to analyze the expected cause of stent collapse and to draw attention to the importance of the surveillance follow-up, as this phenomenon may occur late postdeployment.
Methods A retrospectively collected dataset from the two highest volume trauma centers in Saudi Arabia was analyzed between April 2007 and October 2012. A total of 66 patients received stent grafts for traumatic aortic injury and were included in the study. We apply Ishimaru's anatomical aortic arch zones and Benjamin's aortic injury grading systems. There were 35 patients with aortic injury at zone 2, 26 patients in zone 3, and 5 patients in zone 4. About 96% (63) of the injuries were grades 2 and 3, including large intimal flap or aortic wall pseudoaneurysm with change in wall contour. The technical success rate, as defined by complete exclusion of lesions without leaks, stroke, arm ischemia or stent-related complications, was 90%.
Results Proximal stent collapse occurred in 4.5% of patients (3 of 66 inserted stents) during follow-up of 4 to 8 years (mean, 6 years). Patients with stent collapse tended to have an acute aortic arch angle with long-intraluminal stent lip, when compared with patients with noncollapsed stents. Intraluminal lip protrusion more than 10-mm increased collapse (p < 0.001). Stent-grafts sizes larger than 28 mm also demonstrated a higher collapse rate (p < 0.001).
Conclusions The risk of stent collapse appears related to poor apposition of the stent due to severe aortic arch angulation in young patients and to large stent sizes (>28 mm). Such age groups may have more anatomical and aortic size changes during the growth. Clinical and radiological surveillance is essential in follow-up after stent-graft treatment for traumatic aortic injury.
Objective:
The arteriovenous fistula (AVF) is the preferred access type for hemodialysis, owing to its better patency rates and fewer complications. This study aimed to evaluate the outcome of percutaneous transluminal angioplasty in a failing arteriovenous fistula and arteriovenous graft in hemodialysis patients.
Methods:
Clinical data of patients who underwent percutaneous transluminal angioplasty in the vascular department of Aseer Central Hospitals, KSA, from January 2017 to May 2018 and with follow-up of >12 months were analyzed in retrospective cohort study.
Results:
Angioplasties were performed in 55 patients with fistulae, of which 18 patients had venous hypertension on dialysis and the remaining patients had weak or poor flow.
Conclusions:
Percutaneous transluminal angioplasty is an efficacious method for the correction of stenosis of arteriovenous fistulae for patients on hemodialysis, prolonging the patency of the fistula and enabling new interventions.
Highlights:
Arterio-esophageal fistula (AEF), whether congenital or acquired, is a rare condition which can lead to fatal upper gastrointestinal bleeding. We report here a young man who developed a subclavian-esophageal fistula (SEF) secondary to chicken bone impaction in the upper esophagus. The diagnosis was reached by urgent upper endoscopy and Computed Tomography of the chest which showed pseudo-aneurysmal changes at left subclavian artery with leaked contrast through the fistula towered the esophagus. Urgent endo-vascular angiography confirmed the subclavian arterio-esophageal fistula that was managed uneventfully using covered 6mm Viban stent-graft. The patient survived this serious condition and was discharged home in good condition.
