Background: An invasive phlebological treatment is still not free from complications such as thrombosis. As in other surgical populations, not only the treatment modality, but also patient condition-related venous thromboembolism (VTE) risk factors matter. The current protocols used in varicose vein surgery centers are based mostly on individual risk assessment as well as on an implementation and extrapolation of general surgery VTE prophylaxis guidelines. In the presented study, the efficacy of routine VTE pharmacological thromboprophylaxis in patients undergoing saphenous varicose vein surgery was prospectively evaluated. In the result assessment, VTE risk factor evaluation and Caprini score results were included; however, due to the limited size of the projected study group, as well as expected limited deep vein thrombosis (DVT) prevalence in this clinical scenario, it was not possible to perform the validation of the Caprini model efficacy in the projected study model. Methods: In the study, 141 patients undergoing saphenous vein stripping and miniphlebectomy in spinal anesthesia were included. In all of the patients, VTE risk factors (including Caprini score evaluation) were assessed, and the routine thromboprophylaxis with enoxaparin 40 mg for 10 days was used. The venous ultrasounds were undertaken before the surgery and on the 10th and 30th day after surgery. The study endpoint was the presence of symptomatic or asymptomatic DVT confirmed in the imaging study. The study safety endpoint was major bleeding occurrence intraoperatively or within 30 days after surgery. Results: The presence of a postoperative DVT was diagnosed in five cases (3.5%) In all of these cases, only distal DVT was confirmed. Despite extensive saphenous varicose vein surgery with stripping and miniphlebectomy performed in nontumescent but spinal anesthesia, no proximal lower leg episode was diagnosed. Three out of five DVT cases were diagnosed on day 10 postoperative control, while a further two were confirmed in the ultrasound examination performed 30 days after procedure. No clinically documented pulmonaly embolism (PE) as well as no bleeding episodes were noticed. Among the factors related to the statistically significant higher DVT occurrence, the results of the Caprini score were identified with odds ratio (OR) = 2.04 (95% CI = (0.998; 4.18)). Another factor that became statistically significant in terms of the higher postoperative DVT prevalence was the reported Venous Clinical Severity Score (VCSS) results (OR = 1.98; 95% CI (1.19; 3.26)). In the multiple logistic regression analysis, the patient age (OR = 0.86; 95% CI (0.75–0.99)), Caprini score evaluation results (OR = 4.04; 95% CI (1.26–12.9)) and VCSS results (OR = 2.4; 95% CI (1.23–4.7)) were of statistical significance as predictors for postoperative DVT occurrence, with a p value of 0.029 for age, and p = 0.017 and p = 0.009 for Caprini score results and VCSS results, respectively. Due to the confirmed limited number of the DVT events in our study cohort, as well as the descriptive and explorative nature of the achieved results, the final clinical potential and significance of the identified parameters, including Caprini score rate and VCSS rate, should be interpreted with caution and studied in the further trials in these clinical settings. Conclusion: All the patients undergoing varicose vein surgery should undergo VTE risk evaluation based on the individual assessment. In VTE risk evaluation, patient and surgical procedure characteristics based on the factors included into the Caprini score but also on specific chronic venous disease-related factors should be taken into consideration. Further studies are needed to propose an objective and validated VTE risk assessment model, as well as a validated antithrombotic prophylaxis protocol in this particular patient group.

Varicose Vein Surgery

Chronic venous insufficiency (CVI) is a common vascular disorder that affects a significant proportion of the population in the United States and other developed countries. In its advanced stages, CVI significantly reduces patients’ quality of life and imposes a high economic burden on society due to increased direct health care costs and reduced productivity. Favorable clinical results associated with endovascular ablation techniques and patient preference for minimally invasive procedures has led to a shift in which treatment of vein disease is moving from the hospital to the office, allowing a more diverse group of physicians to enter a field that had typically been the domain of surgeons. This chapter reviews the terminology associated with venous disease, indications for varicose vein surgery, preoperative evaluation, procedural planning, endovenous procedures (endovenous laser ablation, radiofrequency ablation), surgical vein stripping techniques, and foam sclerotherapy. Tables include Clinical severity, Etiology or Cause, Anatomy, Pathophysiology classification; summary of nomenclature changes for the lower extremity venous system; indications for varicose vein surgery; interrogation points in the venous reflux examination; complications associated with treatment modalities used in the management of CVI; and methods of variceal ablation. Figures show an ultrasonographic image of a saphenous eye, placement of a quartz fiber for laser ablation of the great saphenous vein, a typical saphenofemoral junction, surgical stripping  of the great saphenous vein, and microfoam sclerotherapy. This review contains 9 figures, 6 tables and 73 references.

Pregnancy And Delivery

Venous thromboembolism (VTE) is a leading cause of maternal mortality in developed countries. The baseline pregnancy-associated VTE (PA-VTE) risk is further increased by additional maternal, pregnancy, and delivery characteristics. In a recently developed risk prediction model for postpartum VTE, emergency caesarean section, stillbirth, postpartum haemorrhage, pre-eclampsia/eclampsia, infection, and medical comorbidities were the strongest VTE predictors. While the evidence base supporting optimal strategies for reducing the risk of postpartum VTE in general is weak, for women with prior VTE it appears that this risk may be reduced by up to 75% with low-molecular-weight heparin (LMWH). VTE prevention in women with more common VTE risk factors is a knowledge gap in 2020, with widely varying international guideline recommendations. However, there is no debate surrounding the requirement to perform systematic VTE risk assessment in pregnant and postpartum women.

Risk Scoring

Venous thromboembolism (VTE) is a frequent preventable complication among surgical patients. Precise risk assessment is a necessary step for providing appropriate thromboprophylaxis and reducing mortality as well as morbidity caused by VTE. We carried out this work to define the rate of VTE postoperatively, following a Caprini score, and to determine VTE risk factors through a modified Caprini risk scoring system. This multicenter, observational, cohort study involved 2,790,027 patients who underwent surgery in four Vietnamese hospitals from 01/2017 to 12/2018. All patients who were evaluated before surgery by using a Caprini risk assessment model (RAM) and monitored within 90 days after surgery. The endpoint of the study was ultrasound-confirmed VTE. Our data showed that the 90-day postoperative VTE was found in 3068 patients. Most of VTE (46.97%) cases were found in the highest risk group (Caprini score > 5). A total of 37.19% were observed in the high risk group, while the rest (15.84%) were from low to moderate risk groups. The likelihood of occurring VTE was heightened 2.83 times for patients with a Caprini score of 3–4, 4.83 times for a Caprini score of 5–6, 8.84 times for a score of 7–8, and 11.42 times for a score of >8, comparing to ones with a score of 0 to 2 (all p values < 0.05). Thus, the frequency of postoperative VTE rises substantially, according to the advanced Caprini score. Further categorizing patients among the highest risk group need delivering more appropriate thromboprophylaxis.

Is Failure

Objectives: To report the outcome of 100 consecutive medicolegal claims referred to one of the authors (1990–2003) following the development of venous thromboembolism (VTE) in surgical patients. Methods: A retrospective analysis of the experience of a vascular surgeon acting as an expert witness in the United Kingdom. Results: Prophylaxis had been provided to 43 claimants with risk factors, who, unfortunately, still developed a VTE and alleged negligence. Twenty-nine claims involved patients who had not received prophylaxis because they were at low risk. In 25/28 claims where no prophylaxis was provided, despite identifiable VTE risk factors, the claim was successful. Claimants who developed a VTE that had been managed incorrectly were successful whether they had received prophylaxis or not. Settlement amounts, where disclosed, are reported. Conclusions: Failure to perform a risk assessment and to provide appropriate venous thromboprophylaxis in surgical patients is considered negligent. Clinicians looking after all hospitalized patients who are not assessing their patients' risk for VTE and/or not providing appropriate prophylaxis are at risk of being accused of negligence.

This article examines the practice of standard varicose vein surgery including sapheno-femoral and sapheno-popliteal ligation, perforator surgery and surgery for recurrent varicose veins. The technique of exposure of the sapheno-femoral junction and the sapheno-popliteal junction is outlined and advice given on avoidance of complications for both. The evidence regarding methods of closure over the ligated sapheno-femoral junction is examined as is the requirement for stripping and the use of different types of stripper. The requirement to strip the small saphenous vein and the extent of dissection necessary in the popliteal fossa is also examined. Complications of standard varicose vein surgery are outlined. The frequency of wound infection, nerve injury, vascular injury and venous thromboembolism are listed and strategies to avoid these complications are examined.

The purpose of this research is to ascertain the prevalence of postoperative venous thromboembolism in the Department of Surgery at Anosiala University Hospital and to identify risk factors for developing postoperative venous thromboembolism using the Caprini Risk Assessment Model. From December 2017 to October 2019, this was a 22-month prospective cohort research conducted at Anosiala University Hospital. It included all adult patients over the age of 18 who were operated on in an emergency or on a planned basis by the Department of Surgery. This research included 662 participants. Within 30 days after surgery, the risk of venous thromboembolism was 0.3 percent. According to the overall Caprini score, 25.2 percent of patients were classified as having a low risk of venous thromboembolism, 25.2 percent as having a moderate risk, 29.5 percent as having a high risk, and 20.1 percent as having the greatest risk. Patients in the highest risk category (scoring 5) had a substantially increased chance of having venous thromboembolism after surgery (p = 0.0007). Only major open surgery was related with a statistically significant increase in postoperative venous thromboembolism (p = 0.028). Age 75 years, elective arthroplasty, and hip, pelvic, or leg fractures were not linked with postoperative venous thromboembolism statistically significantly (p> 0.05). Our findings indicate that the Caprini risk assessment model might be used successfully to avoid postoperative venous thromboembolism in surgical patients in Madagascar, since patients in the highest risk category had a considerably increased chance of developing postoperative venous thromboembolism.
