RESUMO
Objective: To summarize our hospital's single-center experience of and reflections on the treatment of chronic limb-threatening ischemia (CLTI) of lower limbs combined with diabetes in the past 5 years. Methods: We retrospectively analyzed cases of lower limb CLTI combined with diabetes diagnosed at our hospital from March 2017 to June 2021. The baseline data, surgical information, and follow-up results of the patients were collected. The primary outcome indicator was the patency rate of lower limb target artery within 1 year post-op, and the secondary indicators were the reoperation rate within 1 year post-op and the amputation rate within 1 year post-op. Results: A total of 89 patients with lower limb CLTI combined with diabetes were included in the study. A total of 85 patients underwent percutaneous transluminal angioplasty and the operation of 7 patients ended in failure, with the operation success rate reaching 91.76% (78/85). Three patients underwent femoral popliteal artery bypass grafting with artificial blood vessels and one patient underwent iliac femoral artery bypass grafting with artificial blood vessels, with the success rate of the operations reachign 100% (4/4). Among 78 patients who successfully underwent percutaneous transluminal angioplasty, the median follow-up time was 33 months (13, 64). Two patients died within one year after operation, with the post-op one-year survival rate being 97.44% (76/78). The post-op 1-year reoperation rate was 19.23% (15/78), the 1-year target vascular patency rate (deaths not included) was 85.53% (65/76), and the 1-year amputation rate was 3.85% (3/78). Among the patients who underwent bypass surgery, the follow-up period was 13-48 months. No thrombosis in or re-occlusion of the artificial blood vessels were observed during the follow-up period, and the artificial blood vessels remained unoccluded. Conclusion: Transluminal angioplasty has a relatively ideal rate of postoperative vascular patency. In addition, it is a minimally invasive procedure involving low perioperative risks and is performed under local anesthesia. Therefore, it can be used as the preferred treatment for patients with CLTI. On the other hand, bypass surgery has good long-term patency rate, but it involves higher perioperative risks and the procedure is more invasive. Therefore, bypass surgery can be used as an alternative when transluminal angioplasty ends in failure.

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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
BACKGROUND: Multiple renal artery aneurysms (RAAs) involving multiple branches in a solitary kidney are rare and present a major challenge to surgeons. Ex vivo or in situ repair combined with renal artery revascularization is the classical procedure for these complicated cases, which are not suitable for endovascular repair. The choice of bypass graft remains controversial because of the risk of aneurysmal degeneration for autologous graft. CASE SUMMARY: A 39-year-old female patient presented with left lumbar pain for more than 3 mo. Computed tomography angiography showed congenital absence of the right kidney and three left RAAs involving multiple distal branches. This patient met the criteria for surgical repair due to symptoms of threatened rupture. According to the anatomy and location of multiple RAAs, ex vivo revascularization with saphenous vein graft (SVG) was performed. At the 3-year follow-up, computed tomography angiography demonstrated the aneurysmal degeneration of the Y-shaped SVG. The patient remained asymptomatic and follow-up ultrasound showed no continuous growth of SVG aneurysm. CONCLUSION: SVG aneurysm in RAA revascularization causes us to reflect on the choice of graft, especially for solitary kidney patients.
RESUMO
BACKGROUND: Perioperative emotional disorders of patients underwent abdominal aortic aneurysm (AAA) repair is an emerging area of study, and preoperative mental distress of those patients remains poorly understood. The aim of this study was to investigate the prevalence and identify the risk factors of preoperative anxiety and depression in patients scheduled for AAA repair. METHODS: A total of 189 patients who underwent elective AAA repair between 2015 and 2016 were included in this study. These patients were preoperatively evaluated by Hospital Anxiety and Depression Scale (HADS). Demographics and anxiety and depression scores of the patients were documented. Logistic regression was used to identify the independent risk factors of preoperative anxiety and depression. RESULTS: A total of 150 AAA patients were included in final analysis. Of these 150 patients, 44 patients (29.3%) had borderline anxiety or clinical anxiety, and 42 patients (28.0%) were found to have borderline or clinical depression. Female (odds ratio [OR]: 2.81, 95% confidence interval [CI]: 1.08-7.26), the American Society of Anesthesiologists (ASA) Grade 3/4 (OR: 4.34, 95% CI: 1.13-16.68), higher education (OR: 1.44, 95% CI: 1.02-2.04), and abdominal or back pain (OR: 3.08, 95% CI: 1.20-7.87) were identified as significant independent risk factors of abnormal HADS-anxiety in overall patients; and higher level of education (OR: 1.87, 95% CI: 1.16-3.01) was predictive of anxiety in patients planned for endovascular aortic repair. Besides, higher body mass index (BMI) (OR: 1.18, 95% CI: 1.04-1.33) and abdominal or back pain (OR: 3.93, 95% CI: 1.70-9.11) were predictive of abnormal preoperative HADS-depression in overall patients. CONCLUSION: As for patients scheduled for AAA repair, female, higher ASA, higher level of education, and symptom may be independent risk factors for preoperative anxiety, and symptom and higher BMI may predict preoperative depression.

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.

BACKGROUND: Sarpogrelate is a selective 5-hydroxytryptamine (5-HT) receptor subtype 2A antagonist which blocks 5-HT induced platelet aggregation and proliferation of vascular smooth muscle cells. We compared the efficacy of sarpogrelate-based dual antiplatelet therapies for the prevention of restenosis and target lesion revascularization (TLR) rates comparing with that of clopidogrel after percutaneous endovascular interventions (EVIs) of femoropopliteal (FP) arterial lesions. METHODS: This prospective, multicenter, randomized clinical trial recruited a total of 120 patients with successful EVI of FP lesions at seven centers across China between January 2011 and June 2012. Patients were randomized to receive either sarpogrelate (100 mg trice daily for 6 months, n = 63) or clopidogrel (75 mg once daily for 6 months, n = 57). All patients also received oral aspirin (100 mg once daily for 12 months). Clinical follow-up was conducted up to 12 months postprocedure. RESULTS: There was no significant difference between the two groups in basic demographic data. The restenosis rate was higher in the clopidogrel group (22.80%) than in sarpogrelate group (17.50%), but there was no significant difference between these two groups (P = 0.465). The TLR rate, ipsilateral amputation rate, mortality in all-cause and bleeding rate were also similar in the two groups (P > 0.05). CONCLUSIONS: Aspirin plus sarpogrelate is a comparable antithrombotic regimen to aspirin plus clopidogrel after EVI of FP arterial lesions. Dual antiplatelet therapies might play an important role in preventing restenosis after successful EVI of FP lesions.

Patient, a 59-year-old male coming from an undeveloped area of Sichuan Province, China, was admitted because of chest pain for one month. Compute tomography angiography showed descending aorta pseudoaneurysm at the level of the 6th thoracic vertebra (T6). History of bone tuberculosis and tuberculosis DNA test had confirmed diagnosis of tuberculosis. Interventional surgery was performed 3 days after admission. A covered stent (Medtronic TF 3030C200EE) was deployed slowly and accurately. Digital subtraction angiography showed that the pseudoaneurysm was isolated successfully and completely. The chest pain syndrome was relieved considerably. On the day after surgery, the patient was discharged. Fourteen months later, a recent CT revealed that the stent was in the right place and fluent and no infective clue was detected. The patient did not have any discomfort. Interventional therapy for infective pseudoaneurysm still has long promising prognosis. At the same time, anti-infection therapy is also essential.

BACKGROUND: The aim of this meta-analysis was to compare the clinical outcomes of catheter-directed thrombolysis (CDT) plus anticoagulation with anticoagulation alone in patients with lower-extremity proximal deep vein thrombosis (DVT). PATIENTS AND METHODS: We systematically searched Pubmed, Embase, and the Cochrane Library from inception to October, 2014. All randomized controlled trials (RCTs) and non-randomized studies comparing the clinical outcomes between additional CDT and anticoagulation alone were included. The primary outcomes were postthrombotic syndrome and major bleeding complications. The secondary outcomes included the iliofemoral patency rate, deep venous function, mortality, pulmonary embolism, and recurrent DVT. RESULTS: Three RCTs and 3 non-randomized studies were included. Compared with standard anticoagulation treatment, additional CDT was associated with a significantly higher rate of complete lysis within 30 days (OR = 91; 95 % CI 19.28 to 429.46), a higher rate of 6-month patency (OR = 5.77; 95 % CI 1.99 to 16.73), a lower rate of postthrombotic syndrome (OR = 0.4; 95 % CI 0.19 to 0.96), and a lower rate of venous obstruction (OR = 0.20; 95 % CI 0.09 to 0.44). More major bleeding episodes occurred in the CDT group (Peto OR 2.0; 95 % CI 1.62 to 2.62). CDT was not found to reduce mortality, pulmonary embolism, or recurrent DVT. CONCLUSIONS: Additional CDT therapy appeared to be more effective than standard anticoagulation treatment in improving the venous patency and preventing venous obstruction and postthrombotic syndrome. Caution should be taken when performing CDT given the increased risk of major bleeding. However, no evidence supported benefits of CDT in reducing mortality, recurrent DVT, or pulmonary embolism.

A case of intractable upper gastrointestinal-hemorrhage was reported in a patient with portal hypertension caused by an arterioportal fistula (APF), namely, celiac axis-portal vein arteriovenous fistula. Portal hypertension caused by extrahepatic-APFs is extremely rare. Trauma, malignancy, and hereditary causes are the common etiology of APFs; but were absent in our patient. Our patient represents an unusual case of unexplained APF who presented with portal hypertension and was successfully managed through endovascular aortic repair.

AIM: To determine whether low-dose tacrolimus (TAC) combined with mycophenolate mofetil (MMF) is a safe approach to decrease the incidence of chronic kidney disease (CKD) in liver transplantation (LT) recipients. METHODS: We analyzed the medical records of 689 patients who underwent LT between March 1999 and December 2012 in a single Chinese center. Immunosuppression was initiated with a calcineurin inhibitor (TAC or CSA) and prednisone with or without MMF. CKD is defined by the glomerular filtration rate (GFR), estimated by an abbreviated Modification of Diet in Renal Disease formula, < 60 mL/min per 1.73 m(2) for at least 3 consecutive months after LT. Individuals with TAC trough concentrations ≤ 8 ng/mL at 3 mo after LT were defined as the low-dose group. The incidence of CKD within 5 years was compared between the TAC group and the CSA group, as well as between four subgroups (low-dose and high-dose TAC groups with or without MMF). RESULTS: No difference regarding the occurrence of pre-LT renal dysfunction or that of post-LT rejection was found between the TAC and CSA groups or between the four subgroups. With a definition of GFR < 60 mL/min per 1.73 m(2), the overall incidence of CKD was significantly higher in the CSA group than in the TAC group. The incidence of CKD in the low-dose TAC + MMF group (7.7%) was significantly lower than that observed in the low-dose TAC group (15.9%), high-dose TAC group (24.6%) and high-dose TAC + MMF group (18.5%). The cumulative 1-, 3- and 5-year incidence rates of CKD were 12.7%, 14.5% and 16.7%, respectively. The cumulative 5-year survival rates were 61.7% and 82.2% in patients with or without CKD, respectively. CONCLUSION: In LT patients, the choice of immunosuppressive therapy appears to affect renal function and patient survival.

AIM: To identify risk factors that might contribute to hepatic artery thrombosis (HAT) after liver transplantation (LT). METHODS: The perioperative and follow-up data of a total of 744 liver transplants, performed from February 1999 to July 2010, were retrospectively reviewed. HAT developed in 20 patients (2.7%). HAT was classified as early (occurring in fewer than 30 d post LT) or late (occurring more than 30 d post LT). Early HAT developed in 14 patients (1.9%). Late HAT developed in 6 patients (0.8%). Risk factors associated with HAT were analysed using the χ(2) test for univariate analysis and logistic regression for multivariate analysis. RESULTS: Lack of ABO compatibility, recipient/donor weight ratio ≥ 1.15, complex arterial reconstruction, duration time of hepatic artery anastomosis > 80 min, duration time of operation > 10 h, dual grafts, number of units of blood received intraoperatively ≥ 7, number of units of fresh frozen plasma (FFP) received intraoperatively ≥ 6, postoperative blood transfusion and postoperative FFP use were significantly associated with early HAT in the univariate analysis (P < 0.1). After logistic regression, independent risk factors associated with early HAT were recipient/donor weight ratio ≥ 1.15 (OR = 4.499), duration of hepatic artery anastomosis > 80 min (OR = 5.429), number of units of blood received intraoperatively ≥ 7 (OR = 4.059) and postoperative blood transfusion (OR = 6.898). Graft type (whole/living-donor/split), duration of operation > 10 h, retransplantation, rejection reaction, recipients with diabetes preoperatively and recipients with a high level of blood glucose or diabetes postoperatively were significantly associated with late HAT in the univariate analysis (P < 0.1). After logistic regression, the independent risk factors associated with early HAT were duration of operation > 10 h (OR = 6.394), retransplantation (OR = 21.793) and rejection reactions (OR = 16.936). CONCLUSION: Early detection of these risk factors, strict surveillance protocols by Doppler ultrasound and prophylactic anticoagulation for recipients at risk might be determined prospectively.

Posttraumatic abdominal aortic pseudoaneurysm (AAP) is a rare but life-threating disease. Here, we described a case of posttraumatic AAP with acute abdominal aortic occlusion and its successful treatment using a unique hybrid procedure. An 18-year-old male was referred, with a giant AAP among visceral arteries, which occluded the aorta and left renal artery. An infrequently used ventricular septal device was delivered via femoral access and successfully plugged the tear. Then the isolated pseudoaneurysm was resected through open surgery without major bleeding. At 6 months after operation, the patient was alive without evidence of complications. This hybrid procedure combining transcatheter device closure and open surgery was a successful attempt in the subemergency treatment of posttraumatic AAP.

OBJECTIVE: To establish a new reliable experimental abdominal aortic aneurysm (AAA) rat model that simulates human aneurysms and has high survival rate. METHODS: Twenty-four SD rats were randomly divided equally into two groups (male: female=1: 1). Intraluminal saline infusion was given to rats in group A. Rats in group B were given intraluminal elastase infusion and extraluminal calcium chloride application. The diameter of abdominal aorta was measured and eventually harvested at 4 weeks. Successful AAA formation was defined as a dilation ratio )50%. HE stain was applied to evaluate the histology changes of aorta. RESULTS: Group A had a survival rate, technical success rate and AAA formation rate of 83. 3%, 91. 67%, and 0% respectively, compared with 91. 67%, 100%, and 90. 91% in group B. The AAA formation rate in group B was significantly higher than that in group A (P<0. 05). The dilation ratio during infusion was 50. 82% ±4. 11% in group A and 48. 19% ± 3. 89% in group B. The dilation ratio after infusion was 29. 55% ± 4. 69% in group A and 27. 89% + 4. 28% in group B. The difference of dilation ratio between the two groups was not significant. The post-surgery (28 d) dilation ratio was 27. 89% ± 4. 28%0 in group A and 88. 98% ± 42. 33% in group B (P< 0. 05). Fusiform aneurysms, local adhesion and calcification were found in group B. Rats in group B also had thickening intimal, degenerated matrix in media, loss of elastin fiber, apoptosis of vascular smooth muscle cells and transmural inflammation, none of which was observed in group A. CONCLUSION: With improved operative procedure, intraluminal elastase infusion and extraluminal calcium chloride application can create reliable AAA rat model.

BACKGROUND: Biliary atresia (BA) is a major cause of chronic cholestasis, a fatal disorder in infants. This study was undertaken to evaluate the safety and effectiveness of primary living donor liver transplantation (LDLT) in comparison with the traditional first-line treatment, the Kasai procedure. METHODS: We assessed 28 children with BA at age of less than two years (3-21.3 months) who had undergone LDLT in two hospitals in Southwest China during the period of 2008-2011. Eighteen children who had had primary LDLT were included in a primary LDLT group, and ten children who had undergone the Kasai operation in a pre-Kasai group. All patients were followed up after discharge from the hospital. The records of the BA patients and donors were reviewed. RESULTS: The time of follow-up ranged 12-44.5 months with a median of 31 months. The 30-day and 1-year survival rates were 85.7% and 78.6%, respectively. There was no significant difference in the 30-day or 1-year survival between the two groups (83.3% vs 90% and 77.8% vs 80%, P>0.05). The main cause of death was hepatic artery thrombosis. There were more patients with complications who required intensive medical care or re-operation in the pre-Kasai group (8, 80%) than in the primary LDLT group (9, 50%) (P=0.226). But no significant differences were observed in operating time (9.3 vs 8.9 hours, P=0.77), intraoperative blood loss (208.6 vs 197.0 mL, P=0.84) and blood transfusion (105.6 vs 100.0 mL, P=0.91) between the two groups. The durations of ICU and hospital stay in the primary LDLT group and pre-Kasai group were 180.4 vs 157.7 hours (P=0.18) and 27 vs 29 days (P=0.29), respectively. CONCLUSIONS: Primary LDLT is a safe and efficient management for young pediatric patients with BA. Compared with the outcome of LDLT for patients receiving a previous Kasai operation, a similar survival rate and a low rate of re-operation and intensive medical care for patients with BA can be obtained.

Diabetic peripheral artery disease and diabetic foot ulcers are leading causes of hospitalization, for patients with diabetes mellitus, and also are the most important causes of amputation of the lower extremity in those patients, which contribute to the increased mortality and cardiovascular death. The incidence of diabetic peripheral artery disease and diabetic foot ulcers shows increasing trend. Diabetic peripheral artery disease and diabetic foot ulcers can be successfully treated only by the multidisciplinary foot-care services which provide more comprehensive and integrated care as compared to ordinary medical team or single specialist. Multidisciplinary foot-care services are provided by the team consist of: diabetologist, diabetes nurse, vascular surgeon, general surgeon, orthopedist, orthopaedic surgeon, podiatrist and orthotist, interventional radiologist and a radiology coordinator, microbiologist, psychologist, educators, shoemaker and rehabilitation team. Contrary to developed countries, multidisciplinary foot-care team has not been constructed in most centres in China. Diabetic education, appropriate foot care, early detection of risk factors of foot ulcers and early intervention are key components in the overall management of diabetic foot disorders and have assumed important roles in programs focused on amputation prevention. Prompt and aggressive treatments of diabetic peripheral artery disease and diabetic foot ulcers can often prevent an exacerbation of the problem and the potential need for amputation, which include correction of biomechanical abnormalities, infection control, serial debridement of ulcers, peripheral revascularization and wound coverage, etc. It is very important to construct a multidisciplinary diabetic foot care team to more effectively improve the survival and prognosis of patients with diabetic peripheral artery disease and diabetic foot ulcers with comprehensive treatments.
