Maleti O, Orso M, Lugli M, Perrin M. Systematic review and meta-analysis of deep venous reflux correction in chronic venous insufficiency. J Vasc Surg Venous Lymphat Disord 2023; 11:1265-1275.e5. [PMID: 37453548 DOI: 10.1016/j.jvsv.2023.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 06/27/2023] [Accepted: 07/01/2023] [Indexed: 07/18/2023]
Abstract
OBJECTIVE The aim of this study was to investigate the technical feasibility, operative techniques, safety, and efficacy outcomes of procedures aimed at correcting deep venous reflux, in patients with chronic venous insufficiency. METHODS We performed systematic literature searches in PubMed, Embase, and Web of Science from databases' inception to February 2022. We included systematic reviews, randomized controlled trials, and observational studies describing surgical procedures to treat patients with deep reflux due to primary and secondary incompetence, post-thrombotic syndrome (PTS). Proportion meta-analyses were performed for all the efficacy and safety outcomes. RESULTS We included 57 studies in the quantitative synthesis: three randomized controlled trials including 252 patients and 54 case series including 4004 patients. Studies included a median of 38 patients, with a mean age of 51 years; 52% of them were males. Forty percent of studies included 2291 patients with primary incompetence, 29% of studies included 595 patients with PTS, and 31% of studies included 1118 patients with both diseases. As for primary incompetence, pooled estimates for all procedures showed an 89% (95% confidence interval [CI], 82%-94%) of ulcer healing, 10% (95% CI, 4%-18%) ulcer recurrence, 98% (95% CI, 93%-100%) valve patency, 84% (95% CI, 78%-90%) valve competence, 0.05% (1/1904 patients) pulmonary embolism, 1% (95% CI, 0%-3%) wound infections, 5% (95% CI, 1%-9%) hematoma, 2% (95% CI, 0%-6%) lymphocele, 2% (95% CI, 1%-4%) thrombosis, 85% (95% CI, 74%-94%) pain improvement, 89% (95% CI, 65%-100%) edema improvement, and 85% (95% CI, 73%-93%) lipodermatosclerosis improvement. Patients with PTS showed less favorable outcomes: 82% (95% CI, 71%-91%) of ulcer healing, 18% (95% CI, 5%-36%) ulcer recurrence, 88% (95% CI, 78%-96%) valve patency, 78% (95% CI, 66%-88%) valve competence, no pulmonary embolism, 6% (95% CI, 0%-22%) wound infections, 6% (95% CI, 3%-10%) hematoma, 5% (95% CI, 1%-12%) lymphocele, 7% (95% CI, 1%-16%) thrombosis, 79% (95% CI, 59%-94%) pain improvement, 75% (95% CI, 61%-88%) edema improvement, and 64% (95% CI, 9%-100%) lipodermatosclerosis improvement. CONCLUSIONS The number of studies included in each meta-analysis are limited, and knowing how this element can affect the statistical power, as well as the absence of comparative control groups, it is not possible to draw definitive conclusions. Nevertheless, deep venous reconstructive surgery for reflux may increase the probability of clinical improvement in patients affected by chronic venous insufficiency. Outcomes appear to be satisfactory even if possible adjunctive procedures may be required over the course of the patient's lifetime. Consequently, a strict follow-up protocol is required to maintain outcomes. Further studies are required to evaluate deep venous reconstructive surgery for reflux particularly as to how it compares with the more recently introduced endovenous approaches.

Abstract
Chronic venous disorder (CVD) is highly prevalent vascular disorder affecting up to 45% of the general population, with clinical manifestations ranging from teleangiectasias to venous leg ulcers (VLUs). We examined the currently available data in order to provide an updated, comprehensive review on treatment options of CVD. We searched MEDLINE, Cochrane, Scopus, EMBASE, ClinicalTrials, and OpenGrey databases for relevant articles in English published until November 2020. Compression treatment is the mainstay of conservative treatment. Pharmacological treatment can provide significant symptomatic relief and hence it should be considered as part of conservative treatment. Transcutaneous Lacer treatment (TCL) is a safe and effective alternative option to sclerotherapy for treatment of C1 stage. High ligation and stripping (HL/S), ultrasound-guided foam sclerotherapy (UGFS), endovenous thermal ablation (EVTA) systems and non thermal non tumescent ablation (NTNT) systems are safe and efficacious first-line options for treatment of saphenous insufficiency. Interventional treatment of co-existing incompetent perforator veins (IPVs) is not supported by contemporary evidence. Regarding deep venous insufficiency (DVI), treatment of symptomatic femoroiliocaval occlusive venous disease refractory to conservative treatment with percutaneous transluminal venoplasty stenting has produced encouraging results.

Abstract
OBJECTIVE To present 18-month clinical results for internal compression therapy (ICT) applied percutaneously and as a novel method in the treatment of primary deep venous insufficiency. MATERIAL AND METHOD Thirty patients diagnosed with isolated primary femoral vein (FV) insufficiency between October 2017 and February 2018 were included in the study. Pre-procedural femoral vein diameters and reflux durations were measured. CEAP classification and Venous Clinical Severity Score (VCSS) were recorded. Pre-procedural CEAP classifications were CEAP 4 in nine patients and CEAP 3 in 21. Quality of life assessments were carried out using a Chronic Venous Insufficiency Questionnaire (CIVIQ-2). FV diameters were then reduced, and valve coaptation was established with the percutaneous application of hyaluronic acid and cyanoacrylate injected adjacent to a valve with non coapting leaflets. Venous diameters and reflux duration were again measured immediately after the procedure. Patients were followed-up at months 1, 6, and 18, at which times all parameters were re-evaluated. RESULTS Eighteen of the 30 patients were women, and 12 were men. The mean duration of the procedure was 22.7 ± 2.9 (20-30) min. Patients' FV diameters were 12.8 (11-14.7) mm before the procedure, 9.9 (9-11.5) mm immediately after, and also 9.9 (9-11.2) mm after 1.5 years (p < 0.001). Pre-procedural reflux duration ranged between 2 and 6 (median: 3) sec, and no reflux was observed in any patient immediately or one month after the procedure (p < 0.001). At 18-month follow-up, reflux lasting only 1 sec was determined in two patients. VCSS scores were 11 (10-12) pre-procedurally and 6 (4-9) at 18 months (p < 0.001). Venous Quality of Life scores were 32 (30-36) before the procedure and 18 (14-24) at 18 months (p < 0.001). CONCLUSION Preliminary investigation of the injection of cyanoacrylate and hyaluronic acid around one valve in an incompetent FV can result in improved hemodynamics, CEAP, VCSS and patient QOL at 18 months, without complications.

Abstract
OBJECTIVES The purpose of this study is to test venous valve performance and identify differences between native tissue and replacement devices developed with traditional tissue treatment methods using a new in vitro model with synchronized hemodynamic parameters and high-speed valve image acquisition. METHODS An in vitro model mimicking the venous circulation to test valve performance was developed using hydrostatic pressure driven flow. Fresh and glutaraldehyde-treated vein segments were placed in the setup and opening/closing of the valves was captured by a high-speed camera. Hemodynamic data were obtained using synchronized hardware and virtual instrumentation. RESULTS Geometric orifice area and opening/closing time of the valves was evaluated at the same hemodynamic conditions. A reduction in geometric orifice area of 27.2 ± 14.8% (p < 0.05) was observed following glutaraldehyde fixation. No significant difference in opening/closing time following chemical fixation was observed. CONCLUSIONS The developed in vitro model was shown to be an effective method for measuring the performance of venous valves. The observed decrease in geometric orifice area following glutaraldehyde treatment indicates a decrease in flow through the valve, demonstrating the consequences of traditional tissue treatment methods.

Abstract
This article considers the potential options for open deep venous reconstructions based on pathologic complication (obstruction vs insufficiency), anatomic location, presence of disease-free venous architecture, and patient need. Other things being equal, less invasive techniques and disease locations will be attempted as first-line therapy. When other options fail and symptoms persist, open venous surgery by means of bypass for obstructive disease and valve repair or replacement for deep venous insufficiency remains a viable option. The basic techniques available and overall success rates of each are considered.

Abstract
The history of venous valve reconstruction extends back to 1968 when Robert L Kistner performed the first internal valve plasty to treat deep venous axial reflux. Throughout the past 50 years other techniques of reconstructive deep venous surgery (RDVS) were developed, not only to repair but also to replace venous valves. And the fact that several surgeons and centers have undertaken RDVS in the treatment of chronic venous insufficiency (CVI) reporting outcomes, has added knowledge to define more clearly the role of this kind of specialized surgery. Patients who may benefit from RDVS are among those where conventional treatment with compression stockings combined with superficial surgery has failed. Ulcer-healing rates of up to 70% have been reported after RDVS and ulcer-free periods of up to 36 months have been generated. But during five-year follow-up, freedom from ulceration period and clinical improvement rates were reduced significantly. This raises then the issue and challenge of durability of RDVS since the average age of patients who can benefit from it is about 50 years.

Abstract
OBJECTIVE The purpose of this study was to evaluate whether tissue-engineered human allogeneic vein valves have a normal closure time (competency) and tolerate reflux pressure in vitro. METHODS Fifteen human allogeneic femoral vein segments containing valves were harvested from cadavers. Valve closure time and resistance to reflux pressure (100 mm Hg) were assessed in an in vitro model to verify competency of the vein valves. The segments were tissue engineered using the technology of decellularization (DC) and recellularization (RC). The decellularized and recellularized vein segments were characterized biochemically, immunohistochemically, and biomechanically. RESULTS Four of 15 veins with valves were found to be incompetent immediately after harvest. In total, 2 of 4 segments with incompetent valves and 10 of 11 segments with competent valves were further decellularized using detergents and DNAse. DC resulted in significant decrease in host DNA compared with controls. DC scaffolds, however, retained major extracellular matrix proteins and mechanical integrity. RC resulted in successful repopulation of the lumen and valves of the scaffold with endothelial and smooth muscle cells. Valve mechanical parameters were similar to the native tissue even after DC. Eight of 10 veins with competent valves remained competent even after DC and RC, whereas the two incompetent valves remained incompetent even after DC and RC. The valve closure time to reflux pressure of the tissue-engineered veins was <0.5 second. CONCLUSIONS Tissue-engineered veins with valves provide a valid template for future preclinical studies and eventual clinical applications. This technique may enable replacement of diseased incompetent or damaged deep veins to treat axial reflux and thus reduce ambulatory venous hypertension.

Abstract
SummaryDVR is defined as a reflux affecting the deep venous system. DVR essentially arises from two etiologies, primary deep valve incompetence (PDVI) and posthrombotic syndrome (PTS), knowing that axial reflux is correlated with severe chronic venous insufficiency. DVR correction aims at reducing the increased ambulatory venous pressure, which results from reflux in deep veins in orthodynamic conditions.The results of DVR surgery are not easy to assess, as it is mostly combined with surgery for superficial venous system and/or perforators insufficiency.In cases of primary insufficiency, valvuloplasty, the operation of choice, is credited at 5 years follow-up with a 70 % success rate in terms of clinical outcome and improved hemodynamic performance. In PTS, a meta-analysis of transpositions and transplants at more than 5 years estimates successful clinical outcome and improved hemodynamic performance at approximately 50 %. The Maleti neovalve construction technique has achieved by far better results.Indications for DVR surgery are based on clinical, hemodynamic and imaging data. Etiology is a decisive factor in the choice of the technique.

Abstract
At present, no widely accepted surgical options exist for treating chronic deep venous insufficiency (CDVI). Experimental efforts to improve catheter-based management for CDVI have shown disappointing results, hindering application of these techniques in the clinical arena. A review of the literature focusing on technical aspects of valve stent design was conducted. Eight experimental studies were scrutinized to derive data on (1) stent design and configuration; (2) valve design, composition, and configuration; (3) delivery system; (4) functional outcome; and (5) histology to provide a basis for the design of a new prosthetic venous valve. The analysis of available experimental data found that all prosthetic valve designs currently under development/testing rely on some type of a stent to act as a carrier or frame for valve attachment. Most valve models reviewed were for the most part implanted safely and accurately, with good short-term patency and competency. The most commonly reported adverse event was thrombosis, which limited durability. It is assumed that valve configuration determines long-term results after repair. Hence, the newly proposed valve design consisted of 2 stent rings without barbs to fix the valve in the host vein. Because a little reflux might actually benefit the patency of the valve, the valve cusp in the new design forms a billowing "sail" that does not completely open or close, which also prevents the valve cusp from sticking to the wall. This technology remains of great interest to the interventionist and all physicians who are involved in the care for patients with advanced chronic venous disease. Valve design remains a challenge, but promising new valve substitutes such as the one outlined here are under evaluation.
