Effectiveness of Secundum Atrial Septal Defect Occlusion with the Septal Occluder through Right-chest Small Incision: Clinical Analysis of 140 Cases.

Objective To evaluate the feasibility and effectiveness of secundum atrial septal defect(ASD)occlusion with the septal occluder through right-chest small incision. Methods The clinical data of 140 secundum ASD patients (47 males and 93 females) aged 3-63 years who were treated in our center from August 2004 to July 2014 were retrospectively analyzed. The diameter of ASD was 6 to 36 mm. Under general anesthesia, all patients underwent intraoperative transtsophageal echocardiography (TEE), during which no associated cardiac deformity was found. All patients received ASD occlusion via a small incision (3-4 cm) at the right anterior chest. The occluders were released with the help of TEE. Results The atrial septal defect closure was successfully completed in 134 cases. Six cases received surgical closure of ASD after the failure of occlusion. The reasons of conversion included postoperative dislodgement of occlusion device (n=2, both were central type with large size) and technically unsuitable for occlusion (n=4, in whom residual shunt was found in 2 case, sieve pore type in 1 case, and intraoperative dislodgement in 1 case). All of these 6 patients were treated surgically under cardiopulmonary bypass. No dislocation of the device or atrial shunt was found within 3 to 48 months after the operation. Conclusion Occlusion via small chest incision of ASD under TEE guidance without cardiopulmonary bypass is a safe, minimally invasive, effective, and convenient treatment and worth clinical application.

[Clinical outcomes of synchronous revascularization on patients concomitant carotid and coronary artery severe stenosis].

OBJECTIVE: To analyze the outcomes of synchronous revascularization for patients concomitant carotid and coronary artery severe stenosis. METHODS: From May 2012 to April 2014, 12 cases who received one-stage operation was retrospective analyzed, including the characteristics, methods of treatment, perioperative complications and health survey 30 days post procedure. Two subgroups were divided according to the different treatment methods on carotid artery, WIC and SF-36 scale were applied to compare the basic condition and recovery situation between 2 groups, the hospital stay time, costs, ventilation time, drainage and blood transfusion volume were also be compared. RESULTS: Totally 30 coronary vessels 8 carotid endarterectomy (CEA) and 5 carotid artery stenting (CAS) were performed on 12 patients. One patient also received coronary artery bypass grafting and bilateral carotid artery revascularization (CEA on right and CAS on left). Two (16.67%) minor stroke, 1 (8.33%) TIA, 1 wound infection occurred within 30 days post procedure, and 11 (91.67%) received blood component transfusion. No myocardial infarction and death occured. The average hospital stay time were (36.5 ± 25.3) days, ventilator application (37.5 ± 31.2) hours, postoperative drainage volume from pericardial and mediastinal was (347.92 ± 105.69) ml, infusion of concentrated red cell was 4.3 U. WIC was (5.57 ± 1.51) in CEA and (4.25 ± 1.50) in CAS subgroup, there was no significantly statistical difference (t = 1.40, P > 0.05). the results of SF-36 was (3.63 ± 1.76) and (5.44 ± 1.05) in CEA and CAS subgroup, there was no significantly statistical difference (t = -1.85, P > 0.05). In hospital stay time, ventilator application time, transfusion and drainage volume, hospitalization costs were also no significant statistical difference between two groups. CONCLUSIONS: The early outcome of synchronous revascularization on concomitant carotid and coronary severe stenosis disease is satisfactory. The clinical results are similar in the CEA and CAS subgroup.

Phlebosclerosis: An overlooked complication of varicose veins that affects clinical outcome: A case report.

BACKGROUND: Phlebosclerosis is a common age-related fibrotic degeneration of the venous wall. It is a disorder rather than a disease, which may cause venous dysfunction and even venous thrombosis. It is rarely reported in patients with varicose veins. CASE SUMMARY: The present report describes the case of a 70-year-old man with varicose veins, vitiligo, and phlebosclerosis. Venous angiography revealed blood reflux in the superficial and deep veins. The patient underwent surgery to remove the saphenous veins. During the operation, a calcified vein resembling a wooden stick was found, which was surprisingly extracted from the thickened venous wall. A cross-section of this wooden stick-like vein revealed venous fibrosis and calcification, obvious thickening of the venous wall, extensive collagen deposition on the venous wall, hyaline degeneration, and venous sclerosis causing closure of the venous lumen. CONCLUSION: This is probably the first report of a wooden stick-like structure being found in the venous wall in patients with varicose veins and venous ulcers. Phlebosclerosis can be observed in the late stage of varicose veins complicated by frequent infections and worse clinical outcomes. Therefore, it is important to be aware of this condition and address it rather than overlook it.

Combination of Vitamin C and Lenvatinib potentiates antitumor effects in hepatocellular carcinoma cells in vitro.

Lenvatinib has become a first-line drug in the treatment of advanced hepatocellular carcinoma (HCC). Investigating its use in combination with other agents is of great significance to improve the sensitivity and durable response of Lenvatinib in advanced HCC patients. Vitamin C (L-ascorbic acid, ascorbate, VC) is an important natural antioxidant, which has been reported to show suppressive effects in cancer treatment. Here, we investigated the effect of the combination of VC and Lenvatinib in HCC cells in vitro. We found that treatment of VC alone significantly inhibited the proliferation, migration and invasion in HCC cells. Additionally, VC was strongly synergistic with Lenvatinib in inhibition of the proliferative, migratory and invasive capacities of HCC cells in vitro. In conclusion, our results demonstrate that the combination of VC and Lenvatinib has synergistic antitumor activities against HCC cells, providing a promising therapeutic strategy to improve the prognosis of HCC patients.

Strategies and challenges in treatment of varicose veins and venous insufficiency.

Patients with varicose veins can be treated with conservative or surgical approaches based on the clinical conditions and patient preferences. In the recent decade, the recommendations for managing symptomatic varicose veins have changed dramatically due to the rise of minimally invasive endovascular techniques. The literature was systematically searched on Medline without language restrictions. All papers on the treatment of varicose veins and venous insufficiency with different procedures were included and reviewed. Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) both are same safe and effective in terms of occlusion rate, and time to return to normal activity. In comparison with RFA or EVLT, Cure conservatrice et Hemodynamique de l'Insufficience Veineuse en Ambulatoire (CHIVA) may cause more bruising and make little or no difference to rates of limb infection, superficial vein thrombosis, nerve injury, or hematoma. In terms of recurrence of varicose veins, there is little or no difference between CHIVA and stripping, RFA, or EVLT. Great saphenous vein recanalization is highest in the ultrasound-guided foam sclerotherapy (FS) group (51%) during 1 year of follow-up. The 2013 National Institute for Health and Care Excellence clinical guidelines recommend surgery as a third-line therapeutic option after EVLA or RFA and sclerotherapy. Although the mechanochemical endovenous ablation (MOCA) is a non-thermal, non-tumescent option and appears to be of similar efficacy to stab avulsion with no potential risk of nerve damage, the overall success rate of MOCA is lower than those of other procedures such as EVLA, RFA, or high ligation and stripping. EVLA is the most cost-effective therapeutic option, with RFA being a close second for the treatment of patients with varicose veins. Endovenous thermal ablation (EVLA or RFA) is recommended as a first-line treatment for varicose veins and has substituted the high ligation of saphenofemoral junctional reflux and stripping of varicose veins. Ultrasound-guided FS is associated with a high recurrence rate and can be used in conjunction with other procedures. MOCA and cyanoacrylate embolization appear promising, but evidence of their effectiveness is required.

[Clinical experience of combined surgical thrombectomy and endovascular intervention for acute deep venous thrombosis].

OBJECTIVE: To evaluate the clinical outcome of surgical venous thrombectomy and simultaneous stenting in patients with acute, symptomatic iliofemoral deep venous thrombosis (DVT). METHODS: From October 2008 to December 2010, a total of 15 patients with acute symptomatic DVT underwent combined surgical venous thrombectomy and endovascular stenting in ipsilateral iliac vein. There were 6 male and 9 female patients, with a mean age of 57.4 years (ranging from 36 to 71 years). All patients underwent Duplex ultrasonography for diagnosis of DVT. The location of thrombosis was femoro-ilio-caval vein in 2 cases, bilateral iliac vein in 1 case and left iliofemoral vein in 12 cases. All patients had leg swelling and 12 cases had severe leg pain. The mean time of symptomatic DVT occurring at operation was 3.3 d. The factors related to DVT were operation in 6 cases, DVT reoccur in 2 cases. Coexist diseases were digestive tract bleeding in 1 case, gastric ulcer in 1 case, hypertension in 3 cases and 1 case had cerebral infarction. The inferior vena cava filter was inserted before thrombectomy, iliac vein compression and residual stenosis were treated with a self-expandable stent after thrombectomy. RESULTS: Intraoperative venography showed severe venous stenosis in all patients including 80% of iliac vein compression syndrome, 18 self-expandable stents were inserted successfully, the procedural successful rate was 100%, the 30-day mortality rate was 0.One case was suffered from hematoma at incision after operation. 3 patients were lost during follow-up. Median follow-up was 10.3 months (ranging from 2 to 26 months). There was no case of re-thrombosis. Leg pain was disappeared in all cases and only 2 patients showed slight leg swelling after excise. CONCLUSION: Combined surgical thrombectomy and endovascular treatment for patients with acute symptomatic iliofemoral venous thrombosis is an effective and safe technique with low morbidity and good clinical results.

Grey relational analysis of benefit of surgical management for abdominal aortic aneurysm.

Grey relational analysis was used to compare the long-term outcomes of endovascular repair (EVAR) versus open repair for patients with abdominal aortic aneurysm (AAA). Patients with AAA undergoing open repair (n = 133) or EVAR (n = 88) from July 1995 to January 2009 were studied retrospectively. Compared with EVAR, longer periods of postoperative intubation and hospital stay (P < 0.001) were required for open repair. The operation time was significantly longer in open surgery than in EVAR (P < 0.001). Patients in the open repair group required larger volumes of intraoperative blood transfusion than those in EVAR (P < 0.001), and they had more of a trend of cardiac failure after surgery than those in the EVAR group. The operative mortality was similar in both groups. On follow-up, the all-cause mortality and the rates of ischemic legs within 5 years had no significant differences between the 2 procedures (P > 0.05). The grey relational grades in EVAR and open repair were 0.673 and 0.936, respectively. Compared with open repair, patients with AAAs undergoing EVAR had fewer complications in the short term and had a similar all-cause mortality in the long term.

Cephalosporin induced disulfiram-like reaction: a retrospective review of 78 cases.

Concomitant ingestion of alcohol and cephalosporin may cause a disulfiram-like reaction; however its fatal outcomes are not commonly known. We retrospectively reviewed 78 patients who had cephalosporin induced disulfiram-like reaction (CIDLR). The patients who had a negative skin test to cephalosporin prior to intravenous antibiotics were included, and those who were allergic to either alcohol or antibiotics were excluded. The average age of 78 patients was 37.8±12.2 (21-60) years. Of the 78 patients, 93.58% of the patients were males, 70.51% of the patients consumed alcohol after use of antibiotics, and 29.49% patients consumed alcohol initially, followed by intravenous antibiotics; however, no significant difference of morbidity was observed in these two groups. All patients were administered antibiotics intravenously. Five of 78 patients (6.41%) developed severe CIDLR too urgently to be rescued successfully. In conclusion, it is important for clinicians to educate patients that no alcohol should be used if one is taking cephalosporin. Also, clinicians should keep in mind that cephalosporin should not be prescribed for any alcoholics.

Management of postoperative complications following splenectomy.

Complications of post-splenectomy, especially intra-abdominal hemorrhage can be fatal, with delayed or inadequate treatment having a high mortality rate. The objective of this study was to investigate the cause, prompt diagnosis, and outcome of the fatal complications after splenectomy with a focus on early diagnosis and management of hemorrhage after splenectomy. The medical files of patients who underwent splenectomy between January 1990 and March 2011 were reviewed retrospectively. The cause, characteristics, management, and outcome in patients with post-splenectomy hemorrhage were analyzed. Fourteen of 604 patients (1.19%) undergoing splenectomy had intraperitoneal hemorrhage: reoperation was performed in 13 patients, and 3 patients died after reoperation, giving the hospital a mortality rate of 21.43%; whereas, 590 of 604 patients (98%) had no hemorrhage following splenectomy, and the mortality rate (0.34%) in this group was significantly lower (P < 0.001). The complications following splenectomy, including pneumonia pancreatitis, gastric fistula, gastric flatulence, and thrombocytosis, in patients with postoperative hemorrhage were significantly higher than those without hemorrhage (P < 0.001). According to the reasons for splenectomy, 14 patients with post-splenectomy hemorrhage were grouped into two groups: splenic trauma (n = 9, group I) and portal hypertension (n = 5, group II). The median interval between splenectomy and diagnosis of hemorrhage was 15.5 hours (range, 7.25-19.5 hours). No differences were found between groups I and II in terms of incidence of postoperative hemorrhage, time of hemorrhage after splenectomy, volume of hemorrhage, and mortality of hemorrhage, except transfusion. Intra-abdominal hemorrhage after splenectomy is associated with higher hospital mortality rate and complications. Early massive intraperitoneal hemorrhage is often preceded by earlier sentinel bleeding; careful clinical inquiry and ultrasonography are the mainstays of early diagnosis.

Prospective study of sarpogrelate hydrochloride on patients with arteriosclerosis obliterans.

OBJECTIVE: To evaluate the effect of sarpogrelate for patients with atherosclerotic obliterans (ASO). PATIENTS AND METHODS: Patients with ASO were randomly divided into sarpogrelate group (n = 92) and control group (n = 84). The patients in sarpogrelate group received sarpogrelate (100 mg, tid), whereas in control group aspirin (100 mg, qd) was administered orally. The patients were followed up monthly to observe any side effect of medication. Clinical manifestation, painless walking distance, Rutherford type and ankle brachial Index (ABI) were studied. RESULTS: In comparison with control group, the severity of pain, Rutherford type 0 and 1 were improved with statistic significance. Incidence of patients with intermittent claudication decreased from 56.6% before treatment to 28.3% after treatment; the painless walking distance was prolonged (116.3 ± 72.3m vs. 243.5 ± 175.3m, P <0.001); ABI values were increased (0.74 ± 0.17 vs. 0.86 ± 0.18; p <0.001). No side effect of medication was observed. CONCLUSION: Sarpogrelate has a therapeutic effect on patients with atherosclerotic obliterans.

Multiple cardiac perforations following radiofrequency catheter ablation: case report and literature reviews.

INTRODUCTION: Multiple cardiac ruptures after radiofrequency catheter ablation that requires surgical repair are uncommon. METHODS AND RESULTS: We describe a 64-year old male patient with paroxysmal atrial fibrillation who had a cardiac tamponade following radiofrequency ablation. Surgical exploration demonstrated two ruptures in the left atrium, one in the right atrium, and one hematoma in the right atrium. MEDLINE, the Cochrane Library, and related databases were searched up to June 2011 without language restrictions, and related literature was reviewed and discussed. The patient has survived from prompt cardiac repair of cardiac ruptures and recovered from surgery without complications. CONCLUSIONS: Urgent exploratory surgery with cardiopulmonary bypass is the key to salvage the patient.

Long-term outcomes of synchronous carotid endarterectomy and coronary artery bypass grafting versus solely carotid endarterectomy.

OBJECTIVE: To compare the effect of combined carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG) with solely CEA. METHODS: During a five-year period ending December 2009, 25 consecutive patients received concomitant CEA and CABG, whereas, 62 consecutive patients underwent only CEA. They were followed at the median for 64.5 months. The Kaplan-Meier method was used to evaluate the survival rate of patients in both groups. RESULTS: There was no significant difference in terms of age, proportion of gender, risk factors of coronary artery disease and carotid artery stenosis. The degree of carotid artery stenosis was identical in both study groups. One patient in CEA/CABG group had 60% stenosis of carotid artery with ulcerative plaque. There was no early death in the short postoperative period. Restenosis was found on ultrasonography in 4 patients in the CEA/CABG group, and 12 patients in the CEA group; no statistical difference was found between both groups (P = 0.952). The intubation time, ICU stay, and hospital stay in CEA/CABG group were longer than in solely CEA group (P <0.001). The median duration of follow-up was 64.5 months (IQR 24-84 months). The survival rate was 88 %(22/25) in CEA/CABG group and 80.6 %(50/62) in CEA group, product-limit analysis showed that there was no significant difference in survival rates between two groups (P >0.05). CONCLUSION: concomitant carotid endarterectomy and CABG can be safely performed, it could prevent stroke and would not increase the overall risk of surgery.
