Secondary aortoesophageal fistula (AEF) is defined as a communication between the aorta and the esophagus, occurring after aortic disease treatment or esophageal procedures, associating very high mortality rates with treatment and being fatal without it. Several treatment strategies have been described in the literature, combining open surgery or endovascular aortic repair with surgical or endoscopic management of the esophageal lesion. We present the case of a 53-year-old patient with a history of open aortic surgery for a giant descending thoracic aortic pseudoaneurysm complicated with secondary AEF, successfully managed using emergency transiliac TEVAR (thoracic endovascular aortic repair), extensive antibiotic therapy associated with nutritional replenishment, and rehabilitation therapy. Novel endovascular and endoscopic devices have been developed, offering less invasive treatment strategies with improved outcomes, especially for high risk surgical patients. This case highlights the importance of a multidisciplinary approach to personalized medicine to manage such complex situations.
Coronary artery fistulas draining into the left ventricle is a rare finding. They can be associated with other congenital cardiac anomalies like ventricular septal defect or tetralogy of Fallot. While most of them are asymptomatic, they can lead to severe cardiac complications like infective endocarditis, heart failure, or myocardial ischemia. Symptomatic coronary artery fistulas can be managed surgically or percutaneously. We present a case of a 61-year-old male patient with both left anterior descending artery and right coronary artery fistulas draining into the left ventricle associated with ascending aorta and root aneurysm. Preoperative assessment for myocardial ischemia and the size and location of the fistulas was performed. The echocardiography stress test was negative. Surgery consisted of replacement of the ascending aorta and reconstruction of the noncoronary sinus with a Dacron patch with aortic valve preservation and no intervention for the coronary artery fistulas. The surgical strategy was adapted for cardioplegia administration to compensate for the volume of coronary blood drained into the left ventricle and for better protection of the distal myocardium.
Superior mesenteric artery aneurysms are a rare pathology, and rupture due to a pancreatic cyst in the context of alcohol-induced pancreatitis is an even rarer condition. The first line of treatment is usually an endovascular approach. We present the case of a 51-year-old male with alcohol-induced pancreatitis, diagnosed with a superior mesenteric artery aneurysm with active bleeding in close contact with a large pancreatic cyst. A covered stent was used to treat this condition. The patient developed hemorrhagic shock 12 h after the procedure and an urgent laparotomy was performed. A second rupture of the arterial wall at the distal end of the stent was observed and in order to obtain distal perfusion, first, an infrarenal aorta to superior mesenteric artery bypass distal to the rupture was performed in order to exclude the aneurysm. Secondly, a bypass originating from the distal end of the first bypass to the distal end of the superior mesenteric artery was performed. The patient had an uneventful recovery and was discharged after 10 days. We reviewed the literature regarding the incidence and the therapeutic management of superior mesenteric artery aneurysm complicated by pancreatic cyst. An advanced search on PubMed from 2004 to 2024 returned 194 results and after applying the inclusion–exclusion criteria, 11 publications were selected. Although the endovascular approach is usually the first line of treatment with obvious advantages for the patient, a patient-tailored approach should be made in such cases and surgery could be the first option, when considering that the mechanism of aneurysm rupture is due to erosion of the arterial wall by the pancreatic enzymes. Surgery has the advantage of cyst drainage and aneurysm exclusion and in our case proved lifesaving.
Pararenal abdominal aortic aneurysm/pseudoaneurysms (PAAA/PAAP) are rare, high-risk complex aortic lesions involving the renal arteries. Management includes open surgical repair (OSR), endovascular aortic repair (EVAR), or hybrid repair, each with specific advantages and limitations. A review of the literature was performed to assess treatment strategies and outcomes for PAAA and PAAP. A PubMed search using relevant MeSH terms identified 184 articles published in the last five years. After applying inclusion and exclusion criteria, 34 studies comprising 6460 patients with complex AAA/AAP were included for analysis. Treatment strategies were predominantly endovascular (79.4%), followed by open (5.8%) and hybrid approaches (2.9%) (11.7% have used EVAR or OSR in the same study). To emphasize difficulties in the management of this pathology, a case report of a large PAAP involving both renal arteries and occluded celiac trunk with retrograde flow from patent superior mesenteric artery (SMA) is presented. Given the complex anatomy and high surgical risk, hybrid treatment was chosen consisting of bilateral ilio-renal Dacron bypasses followed by ChEVAR (chimney stenting of the SMA), with favorable postoperative recovery. The management of PAAP requires an individualized, anatomy- and risk-adapted approach. Open surgical repair remains preferable for younger, low-risk patients for superior long-term durability, whereas endovascular repair offers lower perioperative morbidity in high-risk cohorts. Optimal outcomes are dependent on high-volume centers with multidisciplinary expertise.
