查看更多>>摘要：? 2021 Elsevier Inc.Objective: Renal artery revascularization has been performed to improve blood pressure control and to cure hypertension in patients with renal artery fibromuscular dysplasia (RAFMD). We herein conducted a systematic review and meta-analysis of studies assessing outcomes associated with the treatment of hypertensive RAFMD patients via endovascular angioplasty in order to offer an up-to-date overview of the relative costs and benefits of this approach to revascularization in RAFMD patients. Methods: We systematically searched the PubMed and Embase databases and the Cochrane Central Register for Controlled Trials to identify relevant studies published as of January 15, 2020. Key outcomes of interest in these studies included technical success, the incidence of perioperative complications, cure rates, and overall improvement rates. Results: In total, we identified 36 relevant studies of 1916 total repairs conducted in 1191 patients. Of these included studies, 33 were retrospective, while 3 were prospective. The overall technical success rate across these studies was 94.3%. Rates of total, major, and minor complications in these pooled studies were 12.9%, 4.6%, and 7.4%, respectively. Pooled rates of cured hypertension and improved hypertension following angioplasty, defined according to study-specific criteria, were 37.0% [95% CI: 27.0%–47.0%] and 80.0% [95% CI: 75.0% to 84.0%], respectively, although these rates varied highly among studies. Cure rates for studies used current clinical definitions for substantial variations across studies. Cure rates in studies using current definitions of cured hypertension (blood pressure <140/90 mm Hg without treatment) were just 18.1% following angioplasty. Cure rates fell markedly with increasing mean patient age (OR associated with an increase in mean age of 10 years: -0.24 [95% CI: -0.44 to -0.04, P = 0.019] and with mean known duration of hypertension (OR associated with an increase in mean hypertension duration of 5 years: -0.09 [95% CI: -0.12 to -0.05, P = 0.001]). Conclusions: These findings suggest that endovascular treatment yielded moderate benefits to RAFMD patients, with substantial variation across studies. The blood pressure outcome was strongly influenced by patient age.

The procedure can be performed through different venous accesses such as the transfemoral, transjugular, and the transbrachial access. The aim of this study was to demonstrate the feasibility and safety of the transbrachial approach for transcatheter embolization in this pathology in 201 women. Advantages and disadvantages of this access were discussed. Methods: Between January 2007 and October 2020, female patients who underwent transcatheter embolization for PCS were selected. Embolization procedural details such as venous access sites and embolized veins were collected. Results: Two hundred and one patients were selected for pelvic vein embolization due to PCS. The basilic vein was punctured in 103 patients (51.2%), the cephalic vein was chosen in 76 patients (37.8%) and deep brachial veins in 19 (9.6%). Technical success was observed in 198 (98.5%) cases. Only one major adverse effect was registered; one patient presented with hematoma of the arm that could be managed conservatively. Conclusion: The transbrachial venous approach for PCS embolization is safe, effective and minimal invasive. It provides a significant patient comfort, has a low complication rate and can be performed on an outpatient basis.

We report an interesting case of TB arthritis of the ankle. Methods: We present a 44 year-old diabetic Chinese male with a recent history of worsening pain, swelling, and redness in his left foot with an abscess and X-ray findings consistent with Charcot foot. Results: At first, the presentation was believed to be Charcot's foot with MSSA osteomyelitis but after the wound culture and bone biopsy were both positive for Mycobacterium tuberculosis as well, the diagnosis of tuberculous arthritis was confirmed. Conclusions: While the prevalence of TB and other diseases is low in the majority of the United States, we still need to be aware of such diseases in populations with increasing migration and be cognizant of the potential impact of a patient's background on a diagnosis is critical to properly diagnosing and treating patients. Vascular surgeons may be seeing patients with abscesses of the lower extremities and may miss the diagnosis if cultures for TB are not sought.
查看更多>>摘要：? 2021 Elsevier Inc.Objectives: To propose a contemporary management strategy for venous injury during anterior lumbar spinal exposure that incorporates endovascular treatment. Methods: Vein injuries suffered by patients treated in a single practice were reviewed. A treatment algorithm based on these experiences was formulated. Results: Between 2015 and 2018, 914 patients received anterior access procedures for indicated lumbar interbody fusions. Of these patients, 15 (1.6%) suffered minor vascular injuries treated with manual pressure or suture repair. Four (0.4%) patients undergoing anterior lumbar spine surgery suffered major venous injuries, all of whom received the indicated spinal hardware following endovascular rescue. Primary repair was attempted in three patients before endovascular control and not at all in one. Vascular access was obtained via the bilateral femoral veins in 2 patients, unilateral femoral in one, and bilateral femoral plus right internal jugular vein in one. Stent choice included both uncovered (5, 63%) and covered stents (3, 38%). Deep venous thrombosis occurred in 2 patient's post-treatment. 1 DVT was encountered in the setting of a covered stent and 1 uncovered stent thrombosis was treated with catheter-directed lysis 4 weeks post-operatively. Ultimately, 3 patients were therapeutically anticoagulated. Mean follow-up is 13 months (range 1–36) with duplex ultrasounds available at 6 months or later in 3 of 4 patients. There is no evidence of post-thrombotic syndrome in the 2 patients that developed DVT's or in-stent stenosis in the 3 patients with available follow-up imaging. Conclusions: Endovascular techniques are important adjuncts when controlling large-volume hemorrhage associated with venous tears during anterior spinal exposure. Adequate direct compression allowing occlusion balloon inflation are key steps to reduce blood loss. Covered and uncovered stents are both appropriate choices to treat injuries. Patients must be anticoagulated post-operatively and surveilled for the sequelae of venous insufficiency. With expedient hemostasis, the indicated spinal surgery may be safely completed.
查看更多>>摘要：? 2021 Elsevier Inc.To describe a new inner-branched device used to treat two cases of chronic post-dissection aortic thoraco-abdominal aneurysms (PD-TAAAs) after ascending aortic surgery. A 67-year-old male who had undergone an ascending aorta and arch surgical replacement and a 70-year-old male with a previous Bentall procedure for acute type A aortic dissection were admitted at our department with a PD-TAAA diagnosis. Both patients were defined unfit for open surgery by a multidisciplinary team and a totally percutaneous endovascular repair was planned. A prophylactic cerebro-spinal fluid drainage was applied and at least one hypogastric artery was targeted for salvage in order to reduce the risk of spinal cord ischemia. A new inner branch device by Jotec? (GmbH/ Criolife; Hechingen, Germany/Kennesaw, Georgia) was implanted. A TEVAR and a standard EVAR completed the procedures and a double barrel technique was performed in order to achieve the preservation of the selected hypogastric artery. In both patients the complete technical success was achieved. The postoperative period was uneventful and the patients were discharged on the 6th and 7th postoperative day, respectively. The triple-phase angio-CT performed at 6 months showed the complete false lumen exclusion and the patency of the endografts and of the target visceral vessels. The total endovascular treatment of PD-TAAAs is a fascinating technique with encouraging results in experienced centers. Inner branched devices may expand the field of application of this new technology. More data are required to evaluate mid- and long-term results.
查看更多>>摘要：? 2021Purpose: While endovascular repair of aortic aneurysm (EVAR) has become the mainstay treatment for abdominal aortic aneurysm (AAA), it is not without its disadvantages. Feared complications include graft infections, fistulation and endoleak, the outcomes of which may be life limiting. Case Report: We present a case of a 57 year-old patient with human immunodeficiency virus (HIV) previously treated with EVAR for AAA complicated by endoleak post treatment. He developed an aorto-psoas abscess 2 years later which harboured Mycobacterium avium complex, and medical therapy was unsuccessful. He eventually underwent an extra-anatomical bypass and graft explant, for which an aortoenteric fistula was also discovered and repaired. Conclusion: Infection of endografts post EVAR is relatively rare, and there are presently no guidelines concerning its management. The concomittance of aorto-psoas abscess and aortoenteric fistula is even more uncommon, and necessitated surgical explant for source control purposes in our patient. Lifelong surveillance is required for complications of the aortic stump and bypass patency.
查看更多>>摘要：? 2021Splenic arteriovenous fistula is an uncommon aetiology of portal hypertension, which has definitive treatment effectiveness and good prognosis. We report a case of portal hypertension and gastrointestinal bleeding in the absence of hepatic parenchymal disease in a 50 year-old woman with multiple pregnancies. Abdominal computed tomography and transabdominal arteriography recorded the presence of tortuous and aneurysmal splenic arteries and the premature filling of enlarged splenic veins, which are highly suggestive of splenic arteriovenous fistula. The above vascular abnormalities were successfully treated by transcatheter embolization. No recurrence or other complications were observed. In addition, a literature review concerning splenic arteriovenous fistula published in recent 30 years was performed to further our understanding of the management strategy on this entity.
查看更多>>摘要：? 2021 Elsevier Inc.Introduction: Brachial artery aneurysms constitute 0.5% of peripheral aneurysms. These can be true or secondary to trauma or arteriovenous fistulas. These present as an asymptomatic pulsatile mass or may cause symptoms due to compression of adjacent neurological structures. Case Report: We present a review of the literature on clinical, histological, and therapeutic characteristics of true brachial aneurysms, motivated by the case of a 67-year-old woman with an asymptomatic pulsatile mass dependent on the brachial artery of the left arm who underwent open surgical correction with resection of the aneurysmal sac and interposition of great saphenous vein graft with adequate postoperative results.
查看更多>>摘要：? 2021Background: To describe a retrograde recanalization for the proximal occluded lesion in right renal artery (RRA) in young patient with fibromuscular dysplasia (FMD). Methods: A 10-year-old girl presented to our hospital with proximal RRA occlusion and refractory hypertension though she took anti-hypertension medicines. Her renin and aldosterone were beyond the normal level in both base state and excited state. Her glomerular filtration rate at right kidney was only 18.4 ml/min. Angiography revealed proximal RRA occlusion and a compensated collateral artery (CCA) from the infrarenal aorta to the RRA. She was thus diagnosed with focal FMD. A retrograde recanalization was performed through this CCA. Results: Angioplasty and stenting were successfully performed to treat the proximal RRA occlusion. Postoperatively, the glomerular filtration rate in the right kidney improved. One-year follow-up revealed that, the blood pressure maintained at normal range without any antihypertensive agents. No other discomfort was complained. Conclusions: It is feasible to establish a working pathway with patient's compensated collateral artery to treat the renal artery occlusion.
查看更多>>摘要：? 2021The aim of this article is to present a case of mycotic aneurysm of internal carotid artery secondary to livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) treated with resection and common-to-internal carotid artery bypass with autologous vein graft in a male pig farmer. A 69-year-old man, pig farmer, with recent dental extraction was admitted with a right cervical pulsatile mass, dysphonia, pain, leukocytosis and elevated C-reactive protein (CRP). Ultrasonography (US) and computed tomography angiography (CTA) showed a 3.9 × 4.5 cm mycotic aneurysm of right internal carotid artery with hypermetabolic uptake in positron emission tomography (PET) scan. Resection of the mycotic aneurysm and a common-to-internal carotid artery bypass with major saphenous vein graft were performed. LA-MRSA clonal complex (CC) 398 was detected in intraoperative samples and antibiotic therapy was changed according to antibiogram. Patient was discharged at the seventh postoperative day and received antibiotic therapy for 6 weeks. US 12 months later showed patency of the bypass without collections. Mycotic aneurysms of internal carotid artery are very infrequent. MRSA isolation is rare, and to the best of our knowledge this is the first case caused by multi-drug resistant LA-MRSA CC398. The treatment includes mycotic aneurysm resection and reconstruction with venous graft bypass plus intensive antibiotic therapy.
