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.

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.

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 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.
