Current research progress of diagnosis of iliac vein stenosis based on multi-modal imaging / 国际外科学杂志

Iliac vein stenosis (IVS), known as iliac vein compression syndrome, refers to a series of diseases caused by iliac vein compression or intraluminal adhesions leading to lower extremity vein or pelvic vein drainage disturbance and other clinical manifestations which is quite common in vascular surgery. The vast majority of patients with symptoms of chronic venous insufficiency (CVI) have IVS. In clinical work, IVS does not typically appear as a single symptom, while often combining with other lesions, such as varicose veins of the lower extremities, skin pigmentation, ulcer formation. Studies on its aetiology and epidemiology have found a mean age of onset of 40 years, the age of onset in females is lower than that in males, and the average of stress in females is significantly higher than that in males. Typical IVS occurs mainly in the left lower extremity in young women of reproductive age, but exceptions remain. In summary, the importance of the diagnosis of IVS in clinical practical work can be seen. CVI is a general term for all diseases that affect the morphology and function of the venous system. Compared with chronic venous disease (CVD), CVI include venous system abnormalities without symptoms or signs. Thus, it more accurately describes the diagnosis and treatment of IVS that requires clinical guidance, so its concept is quoted. With the development and advancement of medical imaging, more and more techniques provide help in the diagnosis and treatment of IVS. Therefore, professionals in various specialties have made relevant studies about the benefits and drawbacks of imaging techniques for diagnosis, treatment modalities, and prognostic management of this disease, in order to improve the diagnostic efficacy. Consequently, this review is focused on the current situation of the diagnosis and treatment of IVS under multi-modal imaging, hoping to provide choices of medical imaging technologies for the different states, and to find a better and personalized plan for patients.

Analysis of influencing parameters of intracavitary laser closure in the treatment of varicose veins of the lower extremities / 国际外科学杂志

Varicose veins of the lower extremities are a common disease in vascular surgery and are the result of multiple factors. The clinical manifestations are mainly thickening, tortuosity and dilation of the superficial veins of the lower extremities, which may be accompanied by discomforts such as lower extremity pain and swelling of the lower legs. In severe cases, skin pigmentation of lower extremities, venous ulcers, etc. The current common treatment options include high saphenous vein ligation and stripping, endogenous laser treatment, radiofrequency ablation and foam sclerotherapy, etc. This article reviews some parameter settings and equipment selection that may affect the therapeutic effect and complications of endogenous laser treatment. Hope to help clinicians better choose the device of intracavity laser closure and find the best possible treatment plan for patients.

Progress in endovascular therapies of TASC Ⅱ D aortoiliac occlusive disease / 国际外科学杂志

Aortoiliac occlusive disease is a common and frequently-occurring disease of vascular surgery,and atherosclerosis is the main cause of its disease.Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC Ⅱ) D type of aortoiliac occlusive disease due to complex lesions,the preferred treatment method is aortobifemoral bypass.With the change of treatment concept,in-depth study of kiss stent,and the introduction of reconstruction of aortic bifurcation and integrated stent technology,endovascular therapies has achieved satisfactory short-term and long-term patency rates.At present,endovascular therapies has become the preferred treatment for TASC Ⅱ D aortoiliac occlusive disease.This article reviews the recent advances in endovascular therapies of TASC ⅡD aortoiliac occlusive disease.

Interventional treatment of lower extremity arteriosclerosis obliterans / 中华普通外科杂志

Objective To summarize the clinical efficacy of interventional treatment for lower extremity arteriosclerosis obliterans and its complications.Methods We analyzed sixty-nine patients with lower extremities arteriosclerosis obliterans undergoing interventional treatment from October 2011 to January 2013.During the same period,three patients were referred to us who suffered from the complications of interventional treatment.In these patients,eight were TASC ⅡA type,twenty-one were TASC Ⅱ B,twenty TASC Ⅱ C,and twenty-two TASC Ⅱ D lesions.All patients received CTA or DSA.Seventy patients were treated by interventional treatment,and two who had fractured stent underwent external iliacsuperficial femoral artery bypass grafting using artificial grafts.Results The technique success rate was 100％.The symptoms disappeared after surgery.During interventional treatment,one iliac artery ruptured,one patient suffered from arterial perforation and three patients suffered from distal embolization.Sixty-eight patients were followed-up for 9 ± 4 months.Conclusions Endovascular treatment has good early clinical efficacy.In order to reduce the incidence of complications,indication of interventional treatment should be controlled strictly and manipulation should be careful.

The embryo development and clinical significance of abnormalities of the inferior vena cava / 国际外科学杂志

Abnormalities of the inferior vena cava occur infrequently.Except a few patients,most with the abnormalities of the inferior vena cava have not symptoms and do not need surgical procedure.However,attentions should be pasd to these anomalies in operation,particularly in the retroperiwneal procedure.only when the anomalies are identified before operation,its pessible to avoid the disaster caused by side-damage.Understanding embryo development of the inferior vena cava is usdful to comprehend the generation mechanism and classification of abnormalities of the inferior vena cava and its main branches.Exact judgment to abnormalities of the inferior vens cava has the important clinical significance.
