“…The formation of an iatrogenic arteriovenous fistula after endovenous laser treatment of the great saphenous vein is a rare complication that can occur during percutaneous endovascular interventions [ 83 ]. Tohmasi et al presented a unique case of an iatrogenic superficial femoral artery-common femoral vein fistula with high flow, resulting in right heart failure and distal deep vein thrombosis in which they intervened by placing a covered arterial stent that closure of the arteriovenous fistula and restoration of arterial function [ 84 ].The formation of an iatrogenic arteriovenous fistula (AVF) around the proximal subclavian artery is also an extremely rare event that can hardly be treated in open surgery as a deep dissection around the fistula surrounded by dilated veins would be required [ 85 , 86 ]. In a study coded by Sato et al, the case of a 64-year-old man with AVF between right subclavian artery and the right vertebral vein due to an accidental puncture of the right subclavian artery.…”

Coated stents are defined as innovative stents surrounded by a thin polymer membrane based on polytetrafluoroethylene (PTFE)useful in the treatment of numerous vascular pathologies. Endovascular methodology involves the use of such devices to restore blood flow in small-, medium- and large-calibre arteries, both centrally and peripherally. These membranes cross the stent struts and act as a physical barrier to block the growth of intimal tissue in the lumen, preventing so-called intimal hyperplasia and late stent thrombosis. PTFE for vascular applications is known as expanded polytetrafluoroethylene (e-PTFE) and it can be rolled up to form a thin multilayer membrane expandable by 4 to 5 times its original diameter. This membrane plays an important role in initiating the restenotic process because wrapped graft stent could be used as the treatment option for trauma devices during emergency situations and to treat a number of pathological vascular disease. In this review, we will investigate the multidisciplinary techniques used for the production of e-PTFE membranes, the advantages and disadvantages of their use, the innovations and the results in biomedical and surgery field when used to cover graft stents.

“…An arteriovenous fistula (AVF) is a procedure before maintenance hemodialysis (MHD) in which an artery is surgically connected to a vein so that the vein better processes the amount of blood returned to the body [1][2][3]. Many complications occur in patients undergoing MHD; for example, factors such as arteriosclerosis, repeated puncture, and infection can cause intimal hyperplasia or embolism, which leads to stenosis or occlusion of AVF vessels in patients, seriously affecting the patency of vessels and reducing fistula blood flow [4][5][6].…”

This study is aimed at exploring the diagnostic value of digital subtraction angiography (DSA) based on faster region-based convolutional networks (Faster-RCNN) deep learning for maintenance hemodialysis (MHD) diseases and to provide a theoretical basis for clinical nursing. A total of 50 MHD patients who were clinically diagnosed in the Blood Purification Center were randomly divided into the control group and the experimental group (25 cases for each group). The control group was given routine nursing intervention, and the experimental group was given overall nursing intervention under the supervision of DSA. A faster RCNN multitarget detection network was constructed to analyze the average accuracy of various vascular structures in the test set. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the degree of anxiety and depression. The urine volume before and after the operation, local hematoma after a puncture, the incidence of complications, and nursing satisfaction were recorded. The results showed that the average accuracy of the vein, internal carotid artery, circle of Willis, venous sinus, and venous vessels was 0.876, 0.916, 0.994, 0.925, and 0.732, respectively. The success rate of surgery in the experiment group was higher than that in the control group, and the difference had statistical significance ( P < 0.05 ). The SAS score and SDS score in the experimental group were significantly lower than those in the control group ( P < 0.05 ). The total incidence rate of complications in the experimental group (16.00%) was significantly lower than that in the control group (44.00%) ( P < 0.05 ). The satisfaction rate of the experimental group was significantly higher than that of the control group ( P < 0.05 ). The Faster-RCNN model had the best effect in differentiating the circle of Willis and a poor effect in differentiating venous vessels. DSA based on Faster-RCNN can significantly improve the success rate of puncture in MHD patients. The implementation of holistic nursing intervention under its supervision can significantly reduce postoperative complications and improve patient satisfaction with nursing compared with routine nursing.
