Background: Acute aortic occlusion (AAO) represents potentially fatal acute vascular emergency that requires prompt diagnosis and intervention. Clinical condition of patients with AAO is frequently severely devastated when surgical intervention is questionable. Our objective was to retrospectively review our institutional experience with AAO and assess predictors of intrahospital mortality and morbidity.

Methods: This is a retrospective single-center cohort study with prospectively collected data between January 1, 2005 and January 1, 2018. The total number of 28 consecutive patients with AAO were included in our analysis. Patients with acute aortic thrombosis manifested by bilateral acute limb ischemia were divided in two groups based on potential caues of AAO (embolism or in-situ thrombosis) differentiated according to condition of aortoilical segment.

Results: We identified 28 patients with AAO. All of them underwent either aortobifemoral bypass (N.=20, 71%) or bilateral trans-femoral thrombectomy (N.=8, 29%). The overall in-hospital mortality was 36%. Factors that influenced in-hospital mortality were: paralysis (OR=4.41, 95% CI: 1.88-21.78) and higher lactate values on admission (OR=1.23, 95% CI: 1.09-1.83), postoperative development of severe acute kidney injury (OR=3.08, 95% CI: 1.42-14.66), hemodialysis (OR=10.74, 95% CI: 1.64-109.78) and bowel ischemia (OR=5.19, 95% CI: 1.58-55.63).

Conclusions: Paralysis, higher lactate values, development of acute kidney injury, hemodialysis and bowel ischemia are predictors of worse outcome and may be used for risk stratification of patients with acute aortic occlusion and improve counseling patients and their families about expected postoperative outcomes. Patients with embolism and malignant disease have worse outcome; however, this should be tested in future studies on larger sample.

The role of fEVAR, chEVAR and open repair in treatment of juxtarenal aneurysms: a systematic review.

J Cardiovasc Surg (Torino) 2020 Feb;61(1):24-36

Clinic for Vascular and Endovascular Surgery, Serbian Clinical Center, Belgrade, Serbia.

Introduction: Open repair (OR), fenestrated endovascular aneurysm repair (fEVAR) and endovascular exclusion using parallel graft (chEVAR) are complementary procedures used for treatment of juxtarenal abdominal aortic aneurysm (jrAAA). The aim of our study was to assess available literature and analyze dispersion of OR, fEVAR and chEVAR procedures among reported papers related to treatment of jrAAA.

Evidence Acquisition: The PubMed database was systematically searched using predefined strategy and key words related to treatment of jrAAA on September 28th, 2019. Studies were assessed for eligibility using the inclusion and exclusion criteria with at least five patients treated with at least one of the procedures while systematic reviews, meta-analysis, reviews, comments, editorials and letters were excluded as well as studies without clear classification of the location of the aneurysm, studies not specifying the number of patients treated with each of the techniques or not discriminated between aortic pathologies (juxtarenal, paravisceral and thoracoabdominal), hybrid procedures, endoanchors or with branched stent-graft.

Evidence Synthesis: Overall, 1533 papers were identified while papers that met inclusion criteria were either representing experience of single institution (87 papers) or from multicenter studies (6 papers), national or international registries (18 papers). In the period between January 1977 and December 2017, treatment of 5664 patients with jrAAA was reported in 87 papers as a single institution report. Out of them 2531 (45%) were treated with OR, 2592 (46%) with fEVAR and 541 (9%) with chEVAR. Out of 29 institutions reporting OR, there were 11 (37.9%) with more than 100 treated patients while 21 (41.1%) out of 51 institutions that reported more than 50 jrAAA treated with fEVAR. Only four institutions reported results of all three treatment modalities.

Conclusions: Based on the results reported in the literature, regardless of its complexity and costs, fEVAR for jrAAA has been accepted in substantial number of hospitals worldwide, while number of reported procedures is reaching OR.
