RESUMEN
OBJECTIVES: To analyze the incidence, clinical impact on survival, and risk factors of lower limb ischemia (LLI) of surgical peripheral femoral venoarterial extracorporeal membrane oxygenation (VA ECMO) in the current era. DESIGN: A retrospective analysis of the authors' institutional database of VA ECMO was performed. Patients were divided into 2 groups according to the occurrence of LLI. The primary endpoint was survival to hospital discharge. Risk factors of LLI were searched with multivariate analyses. SETTING: University hospital. PARTICIPANTS: Adult patients receiving peripheral VA ECMO for refractory cardiogenic shock and cardiac arrest. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: From January 2018 to December 2021, 188 patients (mean age: 52.0 ± 14.1 years; 63.8% male, 36.2% female) received peripheral VA ECMO. Male sex was more prevalent in the group without LLI (65.9% v 33.3%; p = 0.031). Twelve (6.4%) patients developed LLI during VA ECMO support (n = 6) or after VA ECMO removal (n = 6). Survival to hospital discharge was not statistically different between patients with and without LLI (50.0% v 48.3%; p = 0.571). Female sex patients were at increased risk for LLI (odds ratio 4.38, 95% CI 1.21-15.81; p = 0.024). CONCLUSIONS: Peripheral femoral VA ECMO through a surgical approach is associated with a low LLI rate, which does not increase the risk of in-hospital mortality. The female sex is an independent risk factor for LLI.

Iatrogenic iliac arteriovenous fistula (IAVF) is an extremely rare complication after lumbar discectomy surgery (LDS), with potentially life-threatening consequences. An IAVF results from the close anatomic relation between the iliac vessels and the last lumbar vertebrae and the corresponding discs. We report the case of a 45-year-old woman who developed a large right IAVF 3 years after L4-L5-S1 laminectomy. The arteriovenous fistula (AVF) was successfully treated with an endovascular technique using a WALLSTENT self- expanding stent. The postoperative period was uneventful, and the patient was discharged from the hospital in good general condition on the third postoperative day.

BACKGROUND/AIM: Multiple aortic mural thrombi at the level of the ascending aorta represent a rare condition, only isolated cases have been reported so far. The aim of the current article was to report the case of a 61-year-old patient diagnosed with this pathology. CASE REPORT: A 61-year-old patient with history of COVID infection six months previously was initially diagnosed with acute upper right limb ischemia and submitted to Fogarty desobstruction. Furthermore, the patient was diagnosed with a free-floating mass in the ascending aorta, for which he was submitted to aortotomy and floating thrombi, measuring 5.6×1.5 cm and 3×1.5 cm, were completely removed. The postoperative outcomes were favorable; at the three month follow up the patient proved to have a perfect circulated aortic lumen and supra-aortic vessels. CONCLUSION: immediate aortic desobstruction followed by reconstruction might be a lifesaving maneuver in ascending aortic thrombosis.

Despite the development of imagistic methods, the differential diagnosis of a right atrial mass may be difficult to be established, the most common pathologies which should be taken in consideration being represented by thrombus, tumors, prominent crista terminalis, or vegetation of infectious endocarditis. In this study, we present the case of a 63-year-old man with chronic kidney disease, in hemodialysis (HD) with a silicone central venous catheter (CVC) with the incidental transthoracic echocardiography (transthoracic echocardiogram, TTE) finding of a tumoral mass of 35x26 mm in the right atrium (RA), not related with the catheter, which was diagnosed as right atrial myxoma and underwent surgical excision. After reviewing the histopathology probe, the diagnosis of right atrial thrombus was confirmed. In conclusion, differentiating intracardiac right atrial masses (RAMs) could may prove challenging. In our patient, clinical presentation and the preoperative investigations could not differentiate the right atrial thrombus from a myxoma, and only the postoperative histopathology diagnosis was able to guide correct diagnosis.
