Aneurisma de arteria iliaca: una causa de dolor abdominal agudo de alto riesgo

El dolor abdominal de alto riesgo es una condición común en los servicios de emergencia y está asociado a una alta morbilidad y mortalidad, si no se diagnostica y trata de manera rápida y precisa. Un hombre con síntomas de cólico nefrítico se presentó en emergencia con dolor abdominal intenso y deterioro clínico. Después de una tomografía, se encontró una imagen aneurismática en la arteria iliaca común primitiva izquierda. El paciente fue trasladado a sala de operaciones para una reparación quirúrgica, pero falleció. El dolor abdominal de alto riesgo requiere un abordaje diagnóstico integral y tratamiento individualizado para prevenir complicaciones graves. El aneurisma de la arteria iliaca complicado es una causa potencialmente grave de dolor abdominal en hombres fumadores de edad avanzada con antecedentes de hipertensión y aterosclerosis.

Life-Threatening abdominal pain is a common condition in emergency departments and it is associated with high morbidity and mortality, if not promptly and accurately diagnosed and treated. A man with symptoms of renal colic presented to the emergency room with severe abdominal pain and clinical deterioration. After a CT scan, an aneurysmatic image was found in the left primitive iliac artery. The patient was taken to an operating room for surgical repair but died. Life-Threatening abdominal pain requires a comprehensive diagnostic approach and individualized treatment to prevent serious complications. The complicated iliac artery aneurysm is a potentially serious cause of abdominal pain in elderly male smokers with a history of hypertension and atherosclerosis.

Nefroprotección en frío para reparo de ectasia aórtica y aneurismas ilíacos bilaterales ante la presencia de riñón ectópico pélvico / Cold nephroprotection for repair of aortic ectasia and bilateral iliac aneurysms in the presence of pelvic ectopic kidney

Resumen Los riñones ectópicos pélvicos solitarios asociados a degeneración aneurismática de las arterias ilíacas y la aorta abdominal son eventos muy raros. Los enfoques quirúrgicos para la corrección de aneurismas con compromiso renal son un desafío por la falta de consenso actual, en especial cuando cursan con riñones ectópicos pélvicos solitarios funcionales asociados. Por tal motivo, una de las estrategias que ha demostrado buenos resultados a corto y mediano plazo es la nefroprotección en frío, la cual puede ser usada con seguridad en estos pacientes. En el caso que se presenta, se evidenció una ectasia aórtica con aneurismas ilíacos bilaterales asociados con un riñón ectópico pélvico solitario en un paciente masculino de 75 años, con hipertensión arterial y dislipidemia. Se realizó una reconstrucción aortoilíaca bilateral y una reconstrucción de la arteria hipogástrica, además de reimplante de la arteria renal ectópica bajo irrigación renal en frío, sin complicaciones y preservación de la función renal.

Abstract Solitary pelvic ectopic kidneys associated with aneurysmal degeneration of the iliac arteries and abdominal aorta are very rare events. Surgical approaches for the correction of aneurysms with renal involvement are challenging due to the lack of current consensus, especially when they are associated with functional solitary pelvic ectopic kidneys. For this reason, one of the strategies that has shown good results in the short and medium term is cold nephroprotection, which can be used safely in these patients. In the present case, aortic ectasia with bilateral iliac aneurysms associated with a solitary pelvic ectopic kidneys was evidenced in a 75-year-old male patient with arterial hypertension and dyslipidemia. Bilateral aortoiliac reconstruction was performed with hypogastric artery reconstruction and reimplantation of the ectopic renal artery under cold renal irrigation, without complications and preservation of renal function.

Clinical application of G-iliac? iliac branch device in the treatment of common iliac artery aneurysm / 国际外科学杂志

Objective:To analyze the safety and efficacy of G-iliac? iliac branch device (IBD) in the treatment of common iliac artery aneurysm.Methods:The clinical data of 7 patients with common iliac artery aneurysm who were treated with G-iliac? IBD and internal iliac artery (IIA) preserved were retrospectively analyzed in the Department of Vascular Surgery, Beijing Friendship Hospital, Capital Medical University from June 2021 to June 2022, and the surgical effects and related complications were analyzed.Results:All 7 patients were male, aged from 57 to 80 years, with an average age of 70.9 years. There were 6 cases of abdominal aortic aneurysm combined with common iliac artery aneurysm and 1 case of simple common iliac artery aneurysm, all of them were successfully applied with G-iliac? IBD to preserve IIA. Cardiogenic shock occurred in 1 patient after the operation. 7 patients were followed up for 3-15 months, with an average of 8 months. During the follow-up period, the iliac artery and IIA stents were all patency, and there was no IBD-related endoleak, stent displacement, buttock claudication, sexual dysfunction, or aortic-related death. The diameter of abdominal aortic aneurysm and common iliac artery aneurysm were stable.Conclusion:For patients with common iliac artery aneurysm, preservation of IIA with G-iliac? IBD is a safe and effective technique with a high technical success rate and IIA patency rate, and has a low complication rate, but the long-term effect still requires more data and longer follow-up data to support.

Fístula arteriovenosa ilíaca à direita por rotura de aneurisma e aneurisma de artéria ilíaca esquerda: tratamento híbrido / Right iliac arteriovenous fistula due to aneurysm rupture and left iliac artery aneurysm: hybrid treatment

Resumo A fístula arteriovenosa (FAV) é uma sequela incomum de rotura espontânea de aneurisma arterial dentro do sistema venoso adjacente. Descrevemos, em um paciente de 74 anos, o tratamento endovascular de FAV ilíaca à direita por aneurisma de artéria ilíaca comum (AIC) roto associado a aneurisma de AIC distal à esquerda, em cuja cirurgia foram preservadas as artérias lombares e mesentérica inferior por necessidade de excluir simultaneamente as artérias hipogástricas. Foram demonstrados os fenômenos na dinâmica do balanço hídrico ocorridos em decorrência da interrupção da FAV. A evolução do paciente foi benigna, com normalização das graves alterações hemodinâmicas que apresentava e com desaparecimento dos sintomas respiratórios atribuídos à hipertensão arterial pulmonar.

Abstract An arteriovenous fistula (AVF) is an uncommon sequela of spontaneous arterial aneurysm rupture into the adjacent venous system. We describe the case of a 74-year-old patient who underwent endovascular treatment of a right iliac AVF caused by a ruptured common iliac artery (CIA) aneurysm and a distal left CIA aneurysm. Surgery preserved the lumbar and inferior mesenteric arteries because of the need to simultaneously exclude the hypogastric arteries. Dynamic fluid balance phenomena provoked by closure of the AVF are described. The patient had a benign postoperative course with normalization of the severe hemodynamic changes presented prior to the intervention and resolution of respiratory symptoms attributed to pulmonary arterial hypertension.

Aneurisma idiopático de artéria ilíaca comum direita em criança de três anos - relato de caso / Idiopathic right common iliac artery aneurysm in a three-year-old child - case report

Resumo A incidência de aneurismas ilíacos em crianças não é conhecida, havendo apenas alguns relatos de casos na literatura sobre o tema. Neste estudo, é relatado o caso de um paciente masculino, 3 anos, com aneurisma sacular isolado na bifurcação da artéria ilíaca comum direita de origem idiopática, que foi submetido a ressecção, ligadura da artéria ilíaca interna e anastomose vascular término-terminal. Após 1 mês de seguimento, foi diagnosticada oclusão assintomática da anastomose. Devido à presença de circulação colateral, não houve repercussões clínicas da oclusão, e a criança apresentou evolução clínica favorável a médio prazo.

Abstract The incidence of iliac aneurysms in children is unknown and there are only a small number of case reports in the literature on the subject. This article describes the case of a 3-year-old male patient with an isolated saccular aneurysm at the bifurcation of the right common iliac artery, of idiopathic origin, which was repaired by resection, ligature of the internal iliac artery and end-to-end vascular anastomosis. After 1 month of follow-up, he was diagnosed with asymptomatic occlusion of the anastomosis. The occlusion had no clinical repercussions because of collateral circulation and the child has had a favorable clinical course over the medium term.

The outcomes of internal iliac artery preservation during endovascular or open surgery treatment for aortoiliac aneurysms / Os resultados da preservação da artéria ilíaca interna durante o tratamento endovascular ou em cirurgia aberta para aneurismas aorto-ilíacos

Abstract Background Internal iliac artery (IIA) preservation continues to be a challenge during open surgery or endovascular repair of abdominal aortoiliac aneurysm (AAIA). Objectives To determine the results in terms of survival and clinical outcomes in patients with aortoiliac aneurysms (AAIA) treated with endovascular (EV) or open surgical (OS) repair. Methods This was a retrospective consecutive cohort study of patients with AAIA who underwent EV or OS repair. Results Post-procedure hospitalization time and intensive care unit stay were both longer in the OS group than in the EV group (7.08 ± 3.5 days vs. 3.32 ± 2.3 days; p = 0.03; 3.35 ± 2.2 days vs. 1.2 ± 0.8 days; p = 0.02, respectively). There were two cases of bowel ischemia (4.7%; OS 8.3% and EV 3.2%; p = 0.48), two cases of buttock claudication (4.7%; OS 8.3% and EV 3.2%; p = 0.48), and one case of sexual dysfunction (2.3% OS), all of them in patients with bilateral occlusion of the internal iliac artery (five patients, 11.6%; p = 0.035). Overall survival at 720 days was 80.6% in the EV group and 66.7% in the OS group (p = 0.58). Conclusions In the present study, OS and EV repair of aortoiliac aneurysms had similar overall survival and outcomes. Preservation of at least one internal iliac artery is associated with good results and no further complications.

Objetivos Determinar os resultados da sobrevida e desfechos clínicos em pacientes com aneurismas aorto-ilíacos (AAIA) que recebem reparo endovascular (EV) ou cirúrgico aberto (CA). Métodos Este foi um estudo de coorte consecutivo e retrospectivo de pacientes com AAIA submetidos a reparo EV ou CA. Resultados Houve maior tempo de internação pós-procedimento e permanência na unidade de terapia intensiva no grupo CA comparado com o grupo EV (7,08±3,5 dias vs. 3,32±2,3 dias; p = 0,03; 3,35±2,2 dias vs. 1,2±0,8 dias; p = 0,02, respectivamente). Houve dois casos de isquemia intestinal (4,7%; CA 8,3% e EV 3,2%; p = 0,48), dois casos de claudicação das nádegas (4,7%; CA 8,3% e EV 3,2%; p = 0,48) e um caso de disfunção sexual (2,3% CA), todos em pacientes com oclusão bilateral da artéria ilíaca interna (AII) (cinco pacientes, 11,6%; p = 0,035). A sobrevida global aos 720 dias foi de 80,6% no grupo EV e de 66,7% no grupo CA (p = 0,58). Conclusões No presente estudo, o EV e o CA para aneurismas aorto-ilíacos apresentaram sobrevida e desfechos clínicos semelhantes. A preservação de pelo menos uma AII está associada a bons resultados e sem complicações adicionais.

Pseudoaneurisma micótico por embolismo séptico en paciente pediátrico con leucemia linfoblástica aguda / Mycotic aneurism for septic embolism in a pediatric patient with acute linfoblastic leukemia

Resumen Los aneurismas pediátricos son raros y pueden se causados por infección al dañar la pared arterial formando una saculación ciega contigua a su lumen denominada pseudoaneurisma micótico. La mayoría de los casos reportados son de pacientes ancianos con comorbilidades y los agentes causantes más frecuentes son Staphylococcus spp, Salmonella spp, Streptococcus spp y raramente hongos. Se presenta el caso de un niño de 3 años con: diagnóstico reciente de leucemia linfoblástica aguda de precursores B en remisión; alto riesgo de recaída por tratamiento incompleto y antecedente de bacteremia por Staphylococcus epidermidis y fungemia por Cándida tropicalis; vegetaciones cardiacas que hacen embolismo a hígado, bazo, pulmón y cerebro, y pseudoaneurisma micótico parcialmente trombosado de la arteria ilíaca común y externa. El diagnóstico temprano de esta entidad es de vital importancia por el riesgo de ruptura y el manejo quirúrgico dependerá de la localización, el tamaño y las complicaciones asociadas.

Abstract Pediatric aneurysms are rare and can be caused for damaging of the arterial wall secondary to an infection, forming a blind sacculation contiguous to its lumen called mycotic pseudoaneurysm. The majority of reported cases are from elderly patients with comorbidities. The most frequent involucre microorganisms are Staphylococcus spp, Salmonella spp, Streptococcus spp and rarely fungi. We present the case of a 3-year-old boy, with a recent diagnosis of acute lymphoblastic leukemia of B precursors in remission, with a high risk of relapse due to incomplete treatment and a history of bacteremia due to Staphylococcus epidermidis and fungemia due to Candida tropicalis; with cardiac vegetations that produce liver, spleen, lung and brain embolism, in whom a partially thrombosed mycotic pseudoaneurysm of the common and external iliac artery is found. The early diagnosis of this entity is of vital importance because of the risk of rupture. Surgical management will depend on the location, size and associated complications.

Treatment options for isolated iliac artery aneurysms and their impact on aortic diameter after treatment

PURPOSE: Isolated iliac artery aneurysm (IIAA) is uncommon. It is frequently treated by endovascular aneurysm repair (EVAR). This study was to evaluate treatment results of IIAA and survey aortic diameter after EVAR. METHODS: Patients treated for IIAA in Seoul St. Mary's Hospital and Bundang Seoul National University from 2005 to April 2016 were retrospectively enrolled. The inclusion criteria of IIAA was >30 mm of iliac artery aneurysm without abdominal aortic aneurysm, which was treated by open surgical repair (OSR) or EVAR. Patients' clinical characteristics, treatment results, and mortality were obtained from electronic medical records. Diameters of aorta and iliac arteries were measured periodically with scheduled interval based on CT scans. RESULTS: Forty-nine patients (40 males; mean age, 71.9 ± 11.1 years) were enrolled. Five ruptured IIAAs were treated with EVAR (n = 1) or hybrid methods (n = 4). The diameter of ruptured IIAAs was 65 ± 31.4 mm, which was not significantly different from that of elective (44.3 ± 17.0 mm). Forty-four elective IIAA underwent 9 OSR, 31 EVARs, and 3 hybrid treatments (15 bifurcated and 12 straight stent-grafts). Treatment success rate was 93.8% without hospital mortality. There were 4 type I endoleak, 1 type II endoleak, and 1 type III endoleak without aneurysm-related mortality during follow-up. However, the aortic diameter was increased over time though there was no change or decrease in common iliac artery's diameter. CONCLUSION: Treatment of IIAA included various endovascular modalities as well as open surgery. Regular surveillance is still needed due to aortic dilatation after its treatment.

Objective To summarize the experiences of endovascular aortic repair (EVAR) for isolated iliac artery aneurysm (ⅡAA).Methods The clinical data of 23 patients with ⅡAA undergoing EVAR from Aug 2008 to Mar 2016 were retrospectively analyzed.There were 5 cases of internal iliac artey (internal iliac artery ⅡA) aneurysm,10 cases of unilateral common iliac artery(common iliac artery CIA) aneurysm,6 cases of bilateral CIA aneurysms.Unilateral ⅡA aneurysm was treated by coil embolization and covering the entrance;CIA aneurysm without involving ⅡA was treated by EVAR with covered stent,those involved unilateral ⅡAs or combined ⅡA aneurysms were treated by EVAR after ⅡA embolization.Those with bilateral ⅡA involvement were repaired by Sandwich technique;Bilateral ⅡA was treated in two phases.Results All endovascular procedures were successfully performed;No patients died during the perioperation period.Intraoperative endoleak found in 5 cases managed by balloon dilatation,or conservatively were cured.23 patients were followed-up for 2-60 months,one rebuilding ⅡA was occluded.One CIA anurysm complicated with endoleak was cured by coils embolization and stenting.Gluteal claudication and erectile dysfunction occured in 4 out of 15 cases with unilateral or bilateral ⅡAs occlusion.Conclusion EVAR is a safe and effective treatment for ⅡAA,after a proper management for ⅡA.

Colon perforation due to embolization coil for internal iliac aneurysm

Coil migration is an extremely rare but hazardous complication of aneurysmal coil embolization. Only 1 case report has described coil migration following endovascular exclusion to gastrointestinal (GI) tract. We report the experience of a case of colon penetration caused by embolization coil placed for internal iliac aneurysm. A 66-year-old man visited the Emergency Department for hematochezia that had persisted for 3 months. Stent insertion and coil embolization of left internal iliac artery aneurysm had been performed on the patient 18 months ago. Colonoscopy was performed. It suggested penetration of sigmoid colon by embolization coil and diverticulum. Angiography revealed extravasation of contrast media at left internal iliac artery. Covered stent deployment was done in the left internal iliac artery. One week after the stent insertion, the patient underwent anterior resection, aneurysm resection, and coil removal. The patient recovered without complications. He was discharged at 2 weeks after the operation.

Endovascular treatment of internal iliac artery aneurysms: single center experience

Abstract Objective: Internal iliac artery aneurysms (IIAA) are rare, representing only 0.3% of aortoiliac aneurysms. Its treatment with open surgery is complex and associated with high morbidity and mortality, which led to increasing application of endovascular solutions. In this study, we aimed to evaluate outcomes of endovascular aneurysm repair (EVAR) of IIAA in one institution. Methods: We retrospectively reviewed all cases of IIAA treated with endovascular techniques between 2003 and 2014. Endpoints were morbidity, mortality, freedom from pelvic ischemic symptoms (buttock claudication, ischemic colitis, and spinal cord injury), and need for reintervention. Results: There were 16 patients, 13 males and 3 females, with mean age of 75.1±7 years. A total of 20 IIAA (4 cases were bilateral), with mean diameter of 37.9 mm, were treated. EVAR was performed in 13 (81.3%) patients, with associated internal iliac artery's outflow occlusion in 2. Iliac branch device was used in one patient. Two patients underwent endovascular IIAA embolization alone. One patient underwent percutaneous, transgluteal, IIAA embolization. IIAA flow preservation in at least one internal iliac artery was possible in 9 (56.3%) patients. Early mortality was 7% (1 case). Early morbidity was 18.8%. Pelvic ischemic complications occurred in 1 (7%) patient with buttock claudication. Late reintervention was needed in 3 patients, none of them for IIAA related complications. Conclusion: Endovascular treatment of IIAA is technically feasible and durable. Although overall morbidity is relatively high, major complications are infrequent and perioperative mortality is low. internal iliac artery flow preservation is technically challenging and, in a significant number of cases, not possible at all.

Dilatation of common iliac arteries after endovascular infrarenal abdominal aortic repair with bell-bottom extension

Abstract Objective: Endovascular techniques to treat abdominal aortic aneurysms results in lower morbidity and mortality rates. However, dilation of the common iliac arteries prevents adequate distal sealing, which compromises the procedure success. The aim of this study is report the long-term outcomes of patients with abdominal aortic aneurysms associated with aneurysm of the common iliac artery following endovascular repair using a bifurcated bell-bottom stent graft. Methods: This is a retrospective study that evaluated patients treated with bifurcated bell-bottom extension stent grafts to repair an infrarenal abdominal aortic aneurysm and who had at least one common iliac artery with dilatation > 1.5 cm for at least 12 months after the endovascular intervention. Results: Thirty-eight patients with a mean age of 70.4±8.2 years were included. Stent graft placement was followed by dilation of the common iliac artery aneurysms in 35.3% of cases; endoleak and reoperation rates were 17.6% and 15.7%, respectively. Younger patients showed a higher rate of artery diameter increase following the procedure. The average arterial dilation was 16% in the first year, 29% in the second year, 57% in the third year and 95% from the fourth year until the end of follow-up. Conclusion: Repair of infrarenal abdominal aortic aneurysms with bifurcated bell-bottom type stents when there is common iliac artery dilation is a good therapeutic option to preserve hypogastric flow. The rate of endoleak was 17.6%, and 15.7% of cases required reoperation. Younger patients are more likely to experience dilation of the common iliac artery after the procedure.

Right iliac arterial aneurysm in a 4-year-old girl who does not have a right external iliac artery

Pediatric arterial aneurysm is rare disease. Among them, idiopathic-congenital arterial aneurysm is extremely rare. This is a case report of right common iliac artery idiopathic aneurysm with absence of right external iliac artery. A 4-year-old girl who had been complaining of intermittent abdominal pain since 2 years prior presented with a right lower abdominal mass that had been palpable since 6 months prior. Abdominal CT revealed a 5.2 cm × 4.5 cm × 5.1 cm, right-sided, partially thrombosed, saccular, iliac artery aneurysm. She underwent to operation, aneurismal resection. A pathological examination confirmed that it was a true aneurysm, considering that all layers of the vascular wall were stretched with no deficit. The patient was discharged 3 days after the surgery without any complication. Five months passed since the surgery, and the patient is doing well without any abdominal or leg pain.

Large Sized Common Iliac Artery Aneurysm with Thrombus Developing a Diagnostic Confusion in a Patient with Sciatica / 대한통증학회지

The causes of sciatica are variable and include musculoskeletal, dermatologic, infectious, neoplastic, and vascular disorders. In many cases, the symptom is usually caused by degenerative disease in the spine with the compression or irritation of spinal nerve. On the other hands, there are also several announced extra-spinal causes including aneurysm, diabetes, and radiation for sciatica in a low rate. Among the extra-spinal cases, aneurysms arising from iliac vessels are sometimes developing a diagnostic confusion with the spinal causes, and delayed diagnosis can lead to poor prognosis. It is very important to pay attention weather the aneurysmal cause is involved in the symptom of sciatica.

Use of Reversed Iliac Leg Stent-Graft for the Treatment of Isolated Aneurysm of Internal Iliac Artery

This is to report the technique of reversed iliac leg stent-graft in endovascular treatment for isolated internal iliac artery (IIA) aneurysm, which had significant size discrepancy between the common iliac artery (CIA) and external iliac artery (EIA) in 3 patients from different hospitals. Three patients were a 85- and two 82-year-old men. Treated were right IIA aneurysms, sized 6.5x6.2 cm, 5.0x4.0 cm, and 4.1 cm in longest diameter, respectively. The diameters of the right CIA and right EIA measured 21 mm/11 mm, 15 mm/11 mm, and 20 mm/10 mm, respectively. In all cases, reversed iliac leg stent-grafts were prepared on-site; unsheathed and mounted upside-down manually, and deployed in each right CIA. Post-stent-graft angiograms showed complete exclusion of the aneurysms, except for minimal type 1 endoleak in one case. This technique is a useful treatment option in patients with isolated IIA aneurysm.

Endovascular repair of bilateral iliac artery aneurysm with branched iliac stents: case report and review of the current literature / 대한외과학회지

Common iliac artery aneurysm (CIA) often occurs in conjunction with an abdominal aortic aneurysm (AAA), which extends into one or both CIAs in 20% to 30% of patients. Conventional endovascular treatment includes coil embolization of the internal iliac artery (IIA), followed by extension of the main bifurcated AAA stent-graft into the external iliac artery. However, complications from intentional occlusion of unilateral or bilateral IIAs are frequent and sometimes serious. Several methods try to preserve the unilateral or bilateral IIA. Here we report a case of concomitant bilateral CIA and AAA successfully treated with bilateral branched iliac stent-grafts.
