Anastomotic aneurysms- 20-years of experience from one center

Abstract

Anastomotic aneurysms may develop after any type of vascular surgery, in different areas of the arterial system, and require reoperation. The frequency of occurrence of the above-mentioned is estimated at 1-5%. material and methods. During the period between 1989 and 2010, 180 patients with 230 anastomotic aneurysms were subject to surgical intervention at the Department of General and Thoracic Surgery, Warsaw Medical University. The study group comprised 21 (11.7%) female and 159 (88.3%) male patients, aged between 30 and 87 years (mean age -62.8 years). In relation to the number of anastomoses aneurysms were diagnosed in 2.1% of cases. Twenty-four (10.4%) patients were diagnosed with recurrent aneurysms. results. Surgical procedures performed were as follows: artificial prosthesis implantation (119), reanastomosis (40), patch plasty (25), graftectomy (19), prosthesis replacement (9), and stent-graft (7) implantation. 195 (84.8%) aneurysms were subject to planned surgery, while 35 (15.2%) required emergency intervention. 77.8% of patients were diagnosed with aseptic aneurysms, while the remaining 22.2% with infected perioperative aneurysms. Good treatment results were obtained in 149 (82.8%) patients. Limb amputations were performed in 19 (10.5%) cases. Twelve (6.7%) patients died as a consequence of infection and general complications. conclusions. Vascular reoperations are a difficult clinical problem and are burdened with a high rate of complications. The above-mentioned often require complex treatment, in order to improve therapeutic results.

Anastomotic Aneurysm Formation after High Flow Bypass Surgery: A Case Report with Histopathological Study

“…In the field of cardiovascular surgery, there are several reports on anastomotic aneurysms occurring after bypass surgery using radial artery or blood vessel prosthesis. 4 , 5) The frequency of an anastomotic aneurysm is estimated to be approximately 1–5%. Although the underlying mechanism leading to an anastomotic aneurysm is currently unclear, it is believed to be due to infection, intimal injury, hypertension and mechanical stress.…”

A rare para-anastomotic femoral artery aneurysm in a patient with history of femoro-popliteal bypass graft occlusion

“…Etiologic considerations of para-anastomotic aneurysms include prosthetic graft infection, an ongoing previous dilatation process [11] or peripheral occlusive disorders [12] . In our case, the prosthetic graft was sterile and taking information from previous imaging studies, most importantly, the ones done for preparation of the femoro-popliteal bypass surgery, no evidence of an aneurysmal process had been shown.…”

Nahtaneurysmen - Ätiopathogenese, Symptomatologie, Diagnostik, Therapie, Outcome und Einflussfaktoren nach offen gefäßchirurgischer und interventioneller Rekonstruktion

“…Studien zeigen einen männlichen Anteil von 80 bis 93 % versus einem weiblichen von 7 bis 20 %. Das Durchschnittsalter wird in der Literatur mit 62,8-66,4 Jahren angegeben [14,18,19,20,21].…”

“…In der Literatur wird eine operative Letalität von 2,7 % bis 7,6 % beschrieben, wobei der Infektionsnachweis die postoperative Morbidität und Letalität erhöht [18,21,25,58] Letalität und Komplikationsrate bei der NA-Versorgung sind höher im Vergleich zur Primär-OP [7]. Revisions-OPs mit erhöhtem Infektionsrisiko, einem höheren Alter und dementsprechend auch einer höheren Multimorbidität der Patienten erklären am ehesten diesen Umstand.…”
