[Two Methods of Internal Iliac Artery Exclusion in Endovascular Aorta Repair: a Middle-long Term Follow-up Study].

OBJECTIVE: To compare the middle and long term results of two internal iliac artery exclusionmethods (with or without coils) in endovascular aorta repair (EVAR). METHODS: Clinical data of patients who underwent EVAR from January 2006 to December 2013 were analyzed retrospectively. The participants were divided into two group: coils were not used in Group A, but were used in Group B. The patients were followed up from June 2006 to June 2014. RESULTS: A total of 137 patients (74 in Group A, 63 in Group B) were included in this study, with a mean age of 71. 6 years. The majority (124) of participants were men. Postoperative 30-day mortality of the participants was 0. 73%. None of the participants developed pelvic and spinal ischemia. Claudication appeared in 9 patients (3 in Group A and 6 in Group B). Ischemia in lower extremity happened in 5 patients (2 in Group A and 3 in Group B). Gluteal sore was reported by 5 patients (1 in Group A and 4 in Group B). One patient from Group B developed gluteal skin necrosis. No statistical difference in ischemia and stent occlusion was found between the two groups (P=0. 301, P=0. 108). However, patients in Group B stayed in hospitals longer (P<0. 001) than those in group A. One patient in Group B developed severe ischemic complication: skin and gluteus necrosis. CONCLUSION: Internal iliac artery exclusions with and without coilsresult in similar middle and long term outcomes measured by ischemic complications.

Multiple Splenic Artery Aneurysms: A Case Report and Review of the Literature.

Background: Multiple splenic artery aneurysms (MSAAs) are rare and there are few reports about their treatment. We herein present a rare case of MSAAs treated with splenectomy combined with endovascular embolization. Methods: A 51-year-old female patient was incidentally diagnosed with MSAAs. Splenectomy combined with endovascular embolization was the chosen treatment. Outcomes: The patient recovered uneventfully and was discharged from the hospital 5 days after splenectomy. The patient has been doing well during the 27-months of follow-up. Conclusion: Combined with the experience of the previous literature, we think splenectomy combined with endovascular embolization is a safe, reliable and minimally invasive treatment for some selected multiple SAAs, depending on several patient parameters, such as the age, sex, aneurysm dimension, aneurysm location, complications, and severity of the clinical findings.

Use of three dimensional-printing in the management of floating aortic thrombus due to occult aortic dissection: A case report.

BACKGROUND: Floating thrombus within the thoracic aorta is a rare entity but may cause systemic embolism. The pathogenesis of floating aortic thrombi is not yet fully understood. No definitive guidelines are available for the management of floating aortic thrombus. CASE SUMMARY: We report a 48-year-old patient, without a history of trauma and infection, who presented with sudden severe back pain. A floating thrombus within the aortic arch was found by computed tomography angiography (CTA). No evidence of coagulopathies was found. However, with the assistance of a three dimensional-printed model, this floating thrombus was identified to be caused by occult aortic dissection (AD). Subsequently, an emergency thoracic endovascular repair was performed. The patient's back pain was rapidly alleviated postoperatively. CTA at 1 year showed no filling defect in the stent-graft and aorta. CONCLUSION: Occult AD is a potential factor causing floating aortic thrombi, endovascular stent-graft exclusion may be an optimal therapeutic choice with promising results. Moreover, the combination of CTA and three dimensional-printed models can contribute to the diagnosis and treatment of floating aortic thrombi due to occult AD.

Successful management of infected right iliac pseudoaneurysm caused by penetration of migrated inferior vena cava filter: A case report.

BACKGROUND: Indwelling inferior vena cava (IVC) filters might cause various complications, including filter penetration, filter fracture, filter migration, and thrombosis of the IVC. Penetration and migration complications are common, while a caudal migrated double-basket filter with associated infected iliac pseudoaneurysm has seldom been reported. CASE SUMMARY: We report a 64-year-old female admitted for sudden onset of severe right abdominal pain after IVC filter placement for 3 mo. The patient had a history of failed endovascular IVC filter retrieval. Computed tomography showed that the retrieval hook of the filter penetrated the right common iliac artery and vein, leading to right iliac artery pseudoaneurysm accompanied by right ureteral obstruction with ipsilateral hydronephrosis, and bilateral iliac veins were occluded. Emergency open repair was performed to remove the IVC filter, the right iliac pseudoaneurysm, and the compromised segments of the iliac veins and IVC with right common iliac artery reconstruction. Staphylococcus aureus was isolated from the tissue culture. The patient was discharged on postoperative day 12 with anticoagulation therapy and antibiotic therapy after discharge. Six-month follow-up computed tomography revealed that the right common iliac artery was patent, and only mild hydronephrosis was detected. CONCLUSION: An indwelling IVC filter, even 'embedded' within organized thrombus, could still cause life-threatening complications. Open procedures remain the last resort for IVC filters with severe complications.

Successful endovascular treatment with long-term antibiotic therapy for infectious pseudoaneurysm due to Klebsiella pneumoniae: A case report.

BACKGROUND: Infectious common femoral artery pseudoaneurysm caused by Klebsiella pulmonary infection is a relatively infrequent entity but is potentially life and limb threatening. The management of infectious pseudoaneurysm remains controversial. CASE SUMMARY: We reported a 79-year-old man with previous Klebsiella pneumoniae pulmonary infection and multiple comorbidities who presented with a progressive pulsate mass at the right groin and with right lower limb pain. Computed tomography angiography showed a 6 cm × 6 cm × 9 cm pseudoaneurysm of the right common femoral artery accompanied by occlusion of the right superficial femoral artery and deep femoral artery. He underwent endovascular treatment (EVT) with stent-graft, and etiology of infectious pseudoaneurysm was confirmed. Then, 3-mo antibiotic therapy was given. One-year follow-up showed the stent-graft was patent and complete removal of surrounding hematoma. CONCLUSION: The femoral artery pseudoaneurysm can be caused by Klebsiella pneumoniae deriving from the pulmonary infection. Moreover, this unusual case highlights the use of EVT and prolonged antibiotic therapy for infectious pseudoaneurysm.
