Abstract
BACKGROUND Spontaneous isolated celiac artery dissection (SICAD) is uncommon, with very few series reported in the literature. The present study aims to describe the clinical characteristics and treatment outcomes of patients with SICAD treated at a single Chilean institution over 20 years. METHODS A retrospective review of all patients from a single academic hospital with SICAD diagnosed between January 2003 and March 2023 was performed. Conservative treatment included antiplatelets, anticoagulation, or both. The normal size of a celiac artery in our population was 7.9 ± 0.79 mm in females and 8.3 ± 1.08 mm in males. We defined a celiac artery with a diameter equal to or more than 12.5 mm as an aneurysmal celiac artery. RESULTS The cohort included 27 patients; 77.8% (n = 21) were males. The median age was 51.0 years (range: 38-84 years). Fourteen (51.8%) patients presented with aneurysmal dilatation. Fourteen (51.8%) patients were treated with antiplatelets, 6 (22.2%) patients with anticoagulation, and 7 (25.9%) with anticoagulation and antiplatelets. One patient was treated with endovascular therapy due to a pseudoaneurysm of the celiac artery detected 10 days after conservative treatment with antiplatelets. The median length of hospital stay was 5 days (range: 2-14 days). Complete remodeling was seen in 6 (22.2%) patients, partial remodeling in 10 (37.0%) patients, and no change was seen in 8 (26.9%) patients. Three (11.5%) patients were lost to follow-up. There were no significant differences between treatments and remodeling outcomes (P = 0.729). The median celiac artery diameter of patients with aneurysmal dilatation was 13.5 mm (range: 12.5-20.5 mm). Systemic arterial hypertension was found more commonly in patients who presented with aneurysmal dilatation than in patients without (87.5% vs. 12.5%, respectively, P = 0.016). Mean follow-up was 41.5 months and median follow-up was 16 months (range: 6-204 months). CONCLUSIONS Most patients with SICAD can be treated conservatively with excellent outcomes. Hypertension was more commonly found in patients with SICAD and aneurysmal dilatation.

Abstract
BACKGROUND Infective native aortic aneurysms (INAAs), formerly called mycotic aneurysms, remain an uncommon disease with significant heterogeneity among cases; hence, there is lack of solid evidence to opt for the best treatment strategy. The present study aims to describe a 20-year experience at a single institution treating this uncommon condition. METHODS Retrospective study of all patients treated for INAA at a single academic hospital in Santiago, Chile, between 2002 and 2022. Clinical characteristics are described, as well as operative outcomes per type of treatment. Nonparametric Mann-Whitney U-test or Kruskal-Wallis tests were performed when appropriate, and results were reported as median and ranges. Survival at given timeframes was determined by a Kaplan-Meier curve, with analysis performed through a Cox regression model. RESULTS During the study period, 1,798 patients underwent aortic procedures at our center, of which 35 (1.9%) were treated for INAA. Of them, 25 (71.4%) were male. One patient had 2 INAAs. Median age was 69.5 years (range: 34-89 years). Of the 36 INAAs, the most frequent location was the abdominal and thoracic aorta in 20 (55.5%) and 11 (30.5%) cases, respectively, followed by the iliac arteries in 4 (11.1%) cases. One (2.7%) patient presented a thoracoabdominal INAA. Overall, endovascular treatment associated with long-term antibiotics was used in 20 (57.1%) patients: 4 of them underwent hybrid treatment. Fifteen (42.8%) patients underwent direct aortic debridement followed by in situ or extra anatomic revascularization. There was a significant difference in age between both treatment strategies (a median of 76.5 years for endovascular versus a median of 57 years for open, P = 0.011). The median hospital stay was 15 days (range: 2-70 days). The early complications rate (<30 postoperative days) was 20% (n = 7). Early mortality rate (inhospital or before postoperative 30 days) was 14.2% (n = 5). Median follow-up was 33 months (range: 6-216 months). The overall survival rates at 1, 3, and 5 years were 69.9% (standard error [SE] 8.0), 61.7% (SE 9.8), and 50.9% (SE 11.8), respectively. Five-year survival rate of patients undergoing endovascular treatment compared with open approach was 45.9% (SE 15.1) versus 80.0% (SE 17.8), respectively (P = 0.431). There were no significant differences in survival between open and endovascular treatment, hazard ratio 3.58 (confidence interval 95%: 0.185-1.968, SE ± 0.45 P = 0.454). CONCLUSIONS Patients treated by endovascular approach were older than patients treated by open approach. Even though, the open group had a higher 5-year survival rate than the endovascular group, not statically significance differences were found between treatments.

Abstract
Acute type A dissection presenting with cerebral malperfusion has high morbidity and mortality. Given the complexity of underlying vascular involvement, it is a challenging clinical scenario. Many of these patients are not deemed surgical candidates. If surgery is considered, it often requires complex aortic arch and neck vessel reconstruction. We present a 48-year-old male with an acute type A aortic dissection that presented with paraplegia and decreased level of consciousness. A Computed Tomography showed occlusion of both common carotid arteries. He was successfully treated with a multi-site perfusion strategy and a Hybrid Frozen Elephant Trunk graft to achieve fast restoration of the cerebral circulation and minimize brain ischemia and permanent neurological damage. From this case, we learn that aggressive arch and neck vessel reconstruction supported by multi-site perfusion could help improve mortality and neurological outcomes in selected patients.

Abstract
Purpose: The objective of this study is to report a case of a 65-year-old woman who presented with pallor and pain of her left arm secondary to a true arterial brachial aneurysm, which was successfully treated with saphenous vein bypass and embolization of the aneurysm sac. A review of the literature is also presented. Case report: A 65-year-old woman presented with an acute onset of pallor and pain of her left forearm, and hand. On physical examination, there was a pulsatile mass at the forearm. A doppler ultrasound showed a fusiform aneurysmal dilatation of the brachial artery of 23 mm of diameter. A dynamic contrast-enhanced MRI angiogram confirmed a fusiform dilation of the distal brachial artery. The patient was scheduled for open repair. A fusiform 20 x 60 mm aneurysm of the distal brachial artery extending to the cubital fossa was found and a brachial artery to radial and ulnar arteries bypass with interposed reverse right saphenous vein was created. Embolization of the aneurysm sac was performed using Gelita-spon ® (Gelita Medical, Eberbach, Germany). A final angiogram showed an adequate perfusion through the bypass to the hand, and no contrast in the aneurysmal sac. Postoperative course was uneventful with discharge on the fourth postoperative day. Conclusion: Revascularization with autologous saphenous vein graft and exclusion of the aneurysm with local embolization is a good treatment alternative in a patient with symptomatic brachial aneurysm with distal embolization.

Abstract
Endovascular embolization of arteries feeding pulmonary sequestrations is a growing therapeutic option. A 51-year-old woman with chest pain and hemoptysis was admitted. During hospitalization she presented 150 mL hemoptysis, hypotension, and hematocrit fell to 23.3%. Contrast-enhanced computed tomography confirmed a pulmonary sequestration irrigated by an aneurysmal artery from the abdominal aorta. The patient underwent endovascular coil embolization of the artery feeding the aneurysm and an Amplatzer device was deployed in the proximal third of the sequestration artery. Subsequent contrast-enhanced computed tomography confirmed complete thrombosis of the aberrant artery feeding the aneurysm and absence of irrigation of the pulmonary sequestration. At 56 months follow-up the patient remains asymptomatic, tomography showed involution of the sequestration and complete thrombosis of the aberrant artery. The challenges presented by the different treatment alternatives are discussed.

Abstract
Primary aortoenteric fistula is the spontaneous communication between the lumen of the aorta and a portion of the digestive tract. The most common cause is the erosion of an abdominal aortic aneurysm into the 3rd or 4th portion of the duodenum. It manifests clinically as gastrointestinal bleeding, with or without abdominal pain and a pulsatile abdominal mass on physical exam. Gastrointestinal bleeding is initially recurrent and self-limiting and progresses to fatal exsanguinating hemorrhage. Endoscopic examination diagnoses only 25% of aortoenteric fistulas because these are usually located in the distal duodenum. Contrast computed tomography of the abdomen and pelvis is diagnostic in only 60% of cases. We report three cases with this condition. A 67-year-old male presenting with an upper gastrointestinal bleeding. He was operated and a communication between an aortic aneurysm and the duodenum was found and surgically repaired. The patient is well. A 67-year-old male with an abdominal aortic aneurysm presenting with abdominal pain. He was operated and anticoagulated. In the postoperative period he had a massive gastrointestinal bleeding and a new CAT scan revealed an aorto enteric fistula that was surgically repaired. The patient is well. An 82-year-old male with an abdominal aortic aneurysm presenting with hematochezia. A CAT scan revealed a communication between the aneurysm and the third portion of the duodenum, that was surgically repaired. The patient died in the eighth postoperative day.

Abstract
BACKGROUND Conventional treatment of deep vein thrombosis (DVT) is anticoagulation, bed rest and limb elevation. Proximal DVT patients with persisting edema, pain and cyanosis of extremities despite of conventional therapy may develop ischemia. Direct treatment of thrombosis becomes necessary. AIM To report our experience with mechanical trombolysis of proximal lower extremity DVT. MATERIAL AND METHODS Retrospective review of medical records of proximal DVT patients treated with thrombolysis between March 2012 and August 2015. Thirteen patients, 14 limbs, median age 34 years (22-85), 8 women, were admitted with pain and swelling of recent onset; one patient with venous gangrene. All patients initially received heparin in therapeutic doses without clinical improvement. RESULTS In all 13 cases, mechanical thrombolysis was performed using AngioJet®, and associated with single dose thrombolytic agent in 9. Additional angioplasty for residual stenosis was performed in 12 (7 stents) and IVCF were implanted in 8. All patients were subsequently anticoagulated. Early outcomes with disappearance of pain and decrease of edema, with no mortality or bleeding complications. The patient with foot gangrene required amputation. CONCLUSIONS Mechanical thrombolysis with a single dose of a thrombolytic agent is safe and effective in patients with proximal DVT with an unfavorable evolution.

Abstract
A 34-year-old [corrected] woman was diagnosed with Loeys-Dietz syndrome. Five months later, the patient presented with a symptomatic 2.6-cm subclavian pseudoaneurysm. Staged endovascular treatment was initiated with left vertebral artery embolization, followed by sac ablation and stent graft exclusion. The pseudoaneurysm cavity was filled with n-butylcyanoacrylate ("glue") via a microcatheter. Despite balloon occlusion of the pseudoaneurysm orifice, a small amount of glue debris embolized to the brachial artery, necessitating a vein bypass. In this case, distal embolization of glue may have been avoided by leaving a microcatheter in the aneurysm sac for glue injection after first deploying the stent graft.

Abstract
OBJECTIVE Clinically evident renal disease is a risk factor for mortality after aneurysm repair. Serum creatinine is widely used as a measure of renal function in the preoperative evaluation of patients. Unfortunately, serum creatinine concentration is influenced by muscle mass, hydration status, and glomerular filtration rate (GFR). Calculated GFR, which takes predictors of muscle mass such as age, gender, and weight into account, is a more sensitive determinant of renal function than serum creatinine. We hypothesized that GFR would more accurately predict mortality after EVAR than serum creatinine. METHODS We retrospectively evaluated our database of 398 patients who underwent EVAR with the AneuRx device between October 1999 and October 2004. There were 340 men and 58 women with a mean age of 73. GFR was calculated using the Cockcroft-Gault equation. The patients were divided into four quartiles by preoperative GFR: I (7 to 45), II (45 to 60), III (61 to 79), and IV (> or =80). Survival was estimated with the Kaplan-Meier method, and heterogeneity of mortality across strata was evaluated using the log-rank test. The GFR quartiles were compared with clinically accepted criteria for abnormal renal function (serum creatinine level > or =1.7). RESULTS Actuarial survival at 48 months was 61.5%, 70.5%, 86.0%, and 85.7% for GFR quartiles I to IV, respectively (P < .003). Thirty-day mortality was 2.2% in quartile I, 3.2% in quartile II, and 0 in quartiles III and IV (P = .03 for q1 + q2 vs q3 + q4, P < .02 for q2 vs q3 + q4). Survival curves for quartiles II to IV were statistically indistinguishable, with quartile II running tangential to the two higher quartiles after the perioperative period. Quartile I fared significantly worse than the other three quartiles for the entire follow-up period (P < .005). According to American Kidney Foundation criteria (GFR <90), 83.3% of patients had abnormal renal function compared with 16.1% with abnormal serum creatinine (>1.7) (P < .0002). CONCLUSION The risk of perioperative and long-term mortality in patients undergoing EVAR is more accurately stratified by using calculated GFR than serum creatinine alone. A GFR <45 is associated with decreased survival after EVAR. Perioperative mortality at a GFR of 45 to 60 is comparable with that of the lower quartile (GFR <45), but late survival is comparable with that of patients with GFR >60. The finding of increased risk of early mortality in patients in the 45 to 60 GFR range, with survivors enjoying good long-term outcome, suggests that these patients may most benefit from the use of alternative contrast agents and periprocedural renal protection techniques.

Abstract
Endoleak after endoluminal abdominal aortic aneurysm repair is a relatively common occurrence. Depending on the type of endoleak involved, treatment strategies range from continued serial observation to urgent re-intervention. Type II, or branch vessel endoleaks, are often benign in terms of their natural history but can potentially be associated with progressive abdominal aortic aneurysm sac expansion, endograft migration, or even aneurysm rupture. Type V endoleaks, also known as endotension, may represent an undiagnosed type I-IV endoleak or a progressive accumulation of transudate through the interstices of the endograft. Treatment strategies therefore hinge on correctly identifying the etiology of the endotension. We discuss the diagnosis and management of type II and V endoleaks, with a focus on a device-specific approach to endoleak treatment.
