1.Hemodynamic Consideration of Thigh-Level Compression Stockings after Greater Saphenous Vein Ablation
Annals of phlebology 2024;22(2):74-76
Compression stockings are widely utilized for various purposes in the management of patients with varicose veins. Their primary applications include alleviating swelling and edema, preventing the progression of varicose veins, minimizing post-operative bleeding, and occluding veins following surgical interventions. Various compression devices, such as compression bandages, elastic or non-elastic stockings, are also commonly employed. Graduated compression stockings are particularly favored both preand post-operatively for varicose vein treatment. These stockings exert higher pressure in the ankle and calf regions, with gradually diminishing pressure towards the thigh.However, concerns remain regarding the efficacy of this reduced pressure in adequately compressing veins in the thigh region. Moreover, silicone band products designed to prevent slipping often induce significant skin side effects, suggesting their avoidance in clinical practice. For these reasons, below-knee compression stockings may be recommended, as they enhance the calf muscle pump function and improve wearing comfort.In cases where thigh-high stockings are necessary, the addition of targeted pads to the affected vein areas may be beneficial in increasing localized pressure to occlude target vein.
2.Clinical Implications of Venous Hypertension in the Management of Chronic Venous Disease
Annals of phlebology 2024;22(2):71-73
In the patient with chronic venous disease, venous hypertension occur which result in inability of calf pumps and conduits in the venous system to maintain a normal pressure and normal flow towards the heart. Venous hypertension is caused by venous reflux, obstruction, a combination of reflux and obstruction or arterio-venous fistula. Compensation for obstruction are the development of collateral vein circulation and lymphatic drainage. The clinical symptoms and signs are a result of the venous hypertension and the lack of compensation. Inability to quantitate these factors in individual patients contributes to an incomplete understanding of the pathophysiology, leading to controversies and significant challenges in managing chronic venous disease.
3.Size Matters for the Treatment of Varicose Veins
Annals of phlebology 2024;22(1):9-13
Varicose veins are consistent with physically dilated superficial veins ≥3 mm. Physiologically, chronic venous insufficiency is an advanced chronic venous disease with functional abnormalities. Essentially, the shape of the vein is directly influenced by hydrostatic pressure. Ambulatory venous pressure is increased as shunt formation and vein will be dilated by the connection with deep venous refluxes. Hydrostatic parodox in varicose veins is that the ambulatory venous pressure is not directly related with vein diameter but with shunt formation with valve insufficiency. Mean ambulatory venous pressure of 10–30 mmHg is considered as normal, 31–45 mmHg as intermediate and >45 mmHg as severe venous hypertension. Diameter measurement is used in the diagnosis of varicose veins, but treatment need to be more focused to remove hydrostatic pressure rather than diameter of vein in respect to improve symptoms related with varicose veins. Nevertheless, there are some concerns for the treatment of large veins. From the guidelines endothermal ablation is recommended than non-thermal ablation for >10 mm large varicose vein. Large veins might increase the incidence of endothermal heat induced thrombosis. Caprini score more than 7 will be benefited from chemoprophylaxis for large vein. For the compression therapy, inelastic compression is recommended than elastic compression to improve the function of calf muscle pump.

Purpose:
We sought to identify the risk factors for prolonged hospitalization and delayed treatment completion after laparoscopic appendectomy in patients with uncomplicated acute appendicitis.
Methods:
The study retrospectively analyzed 497 patients who underwent laparoscopic appendectomies for uncomplicated appendicitis between January 2018 and December 2020. The patients were divided into an early discharge group (≤2 days) and a late discharge group (>2 days) based on the length of hospital stay (LOS). The patients were also divided into uneventful and complicated groups according to the need for additional treatment after standard follow-up.
Results:
Thirty-seven patients (7.4%) were included in the late discharge group. The mean LOS of the late discharge groups was 3.9 days. There were significant differences according to age, preoperative C-reactive protein (CRP), and operative time between the 2 groups. Only operative time was significantly associated with prolonged LOS in multivariate analysis. Thirty-five patients (7.0%) were included in the complicated group. The mean duration of treatment in the uneventful and complicated groups was 7.4 and 25.3 days, respectively. Significant differences existed between the uneventful and complicated groups in preoperative body temperature, preoperative CRP levels, maximal appendix diameter, and the presence of appendicoliths. In multivariate analysis, preoperative CRP levels and maximal appendix diameter were independent predictors of delayed treatment completion.
Conclusion
Shorter operative time is desirable to ensure minimal hospital stay in patients with uncomplicated appendicitis. Further efforts are needed to ensure that patients with uncomplicated appendicitis do not experience delayed treatment completion after laparoscopic appendectomies.
5.First-generation therapy for varicose veins: medication, compression, sclerotherapy, and stripping
Journal of the Korean Medical Association 2022;65(4):202-208
Improving the understanding varicose veins (VV) is increasing due to life extension and concerns regarding quality of life. Recently, endovascular treatment has become more common, even in mild cases. Excessive procedures are often performed before conservative and non-surgical treatments. We aimed to explain the efficacy of medication, compression, sclerotherapy, and stripping of treatments and to consider the appropriate indications for many treatment methods, including endovascular procedures.Current Concepts: Venoactive drugs can be used as first-line agents for symptoms, such as edema, at all stages of varicose vein. These are effective adjuvant agents and can help achieve compression before and after procedures. Compression therapy is effective for skin change and ulcers and is excellent for the improvement of symptoms. Sclerotherapy has been widely used as an adjuvant treatment, but recently, its indications have been expanded for non-invasive causes. Traditional high ligation and stripping is still the recommended treatment option for recurrent or complicated varicose veins.Discussion and Conclusion: The patients’ symptoms should be evaluated more critically than assessing only the venous reflux using ultrasound. Additionally, objective evaluation of various causes of lower extremity discomfort should be considered. Treatment according to appropriate indications, such as medication, compression, sclerotherapy, stripping, and endovascular therapy, can improve the patients’ quality of life and prevent complications.

Purpose:
High incidence of osteoporosis has been reported in breast cancer patients due to early menopause triggered by adjuvant treatment and temporary ovarian function suppression. In this study, we sought to determine whether long-term breast cancer survivors had an elevated risk of low bone density compared to the general population.
Methods:
Long-term breast cancer survivors who had been treated for more than 5 years were selected for this study. Data were obtained from medical records and using a questionnaire from the Korea National Health and Nutrition Examination Survey (KNHANES). An agematched non-cancer control group was selected from the KNHANES records. Incidence of fracture and bone mineral density (BMD) were compared between the two groups.
Results:
In total, 74 long-term breast cancer survivors and 296 non-cancer controls were evaluated. The incidence of fracture did not differ between the two groups (P=0.130). No differences were detected in lumbar BMD (P=0.051) following adjustment for body mass index, while hip BMD was significantly lower in breast cancer survivors (P=0.028). Chemotherapy and endocrine treatment were not related to low BMD in breast cancer survivors. In more than half of the survivors, the 10-year risk of osteoporotic fracture was less than 1%.
Conclusion
Long-term breast cancer survivors had low bone density but a comparable risk of fracture compared to non-cancer agematched controls. Further studies on the factors related to low bone density in long-term breast cancer survivors are required.

Morel-Lavallée lesions (MLL) create pre-fascial space by shearing the subcutaneous tissues away from the underlying fascia, in a patient with trauma. Necrosis of the overlying skin can develop over a wide area of the lesion. The lesion might be contaminated by the surgical site due to careless intrusion when treating the combined arteriopathy. A 70-year-old woman presented with avulsion of the skin over the right foot and bilateral leg pain following a car accident. Computed tomography showed bilateral popliteal artery occlusion with large hematoma on both legs. Percutaneous angioplasty was performed with successful restoration of the flow. However, the skin color changes over time. Necrosis of the skin occurred over a wide area of the right leg. Extensive debridement was performed, and the defect was covered with a skin graft. MLLs can occur in patients with multiple traumas, multiple vascular injuries, and complex skeletal injury. Vascular surgeons treating multiple traumas should be aware of the diagnostic and management options for MLL. It should be diagnosed early because it can be difficult to manage once the overlying skin develops necrosis.

Purpose:
We aimed to evaluate the postoperative complications of laparoscopic colorectal cancer (CRC) surgery and the adverse events of postoperative chemotherapy in elderly patients compared to younger patients and to identify the factors influencing the termination of postoperative chemotherapy.
Methods:
Between June 2015 and May 2018, 188 patients with CRC underwent laparoscopic surgery with curative intent.Patients aged ≥ 70 were defined as elderly. Postoperative complications and adverse events of chemotherapy were assessed by using the Clavien-Dindo classification and the Common Terminology Criteria for Adverse Events, respectively. The clinicopathological factors were analyzed retrospectively.
Results:
Seventy-eight patients were considered elderly with a mean age of 77.5 ± 5.5 years. Overall postoperative complications occurred in 68 patients (36.2%). Age and primary tumor location were independent predictors of overall postoperative complications. Smoking history was the only independent predictor of major postoperative complications. Of 113 patients who were recommended postoperative chemotherapy, 90 patients (79.6%) received postoperative chemotherapy.Overall adverse events occurred in 40 patients (44.4%). The American Society of Anesthesiologists physical status classification and chemotherapy regimen were significantly associated with overall adverse events. The chemotherapy regimen was the only factor significantly associated with severe adverse events. Of 90 patients, postoperative chemotherapy could not be completed in 11 (12.2%). Age was the only factor significantly associated with stopping postoperative chemotherapy (P = 0.003).
Conclusion
This study shows that laparoscopic CRC surgery and postoperative chemotherapy were feasible in elderly patients. Further efforts are needed to ensure that elderly patients have the opportunity to make informed decisions regarding postoperative chemotherapy.
9.Cut-down method for perm catheter insertion in patients with completely occluded internal jugular vein
Annals of Surgical Treatment and Research 2019;97(5):266-269
The primary site for a hemodialysis catheter insertion is the right internal jugular vein (IJV) followed by the left IJV and subclavian vein. In cases when veins of the upper extremities are exhausted, femoral veins are an alternative insertion location. Femoral catheter insertions should only be used for short periods because of the increased risk of infection. There is a percutaneous technique to recanalize occluded central veins for hemodialysis catheter insertion. We experienced success with a cut-down method for permcath through a completely occluded IJV. We, therefore, find surgical recanalization to be better than percutaneous method in terms of cost and safety.

PURPOSE: Cardiotoxicity is a serious late complication of breast cancer treatment. Individual treatment risk of specific drugs has been investigated. However, studies on the evaluation of the composite risk of chemotherapeutic agents are limited.METHODS: We retrospectively analyzed the medical records of breast cancer patients who received adjuvant treatment and had available serial echocardiography results. Patients were assigned to subgroups based on chemotherapy containing anthracyclines (A), anthracyclines and taxanes (A+T), and radiotherapy (RT). The development of cardiac disease and serial ejection fraction (EF) were reviewed. EF decline up to 10% from baseline was considered grade 1 cardiotoxicity and EF decline >20% or absolute value < 50% was considered grade 2 cardiotoxicity. The most recent medical records and echocardiography results over 1 year of chemotherapy completion were also reviewed. Late cardiotoxicity was defined as a lack of recovery of EF decline or aggravated EF decline from baseline.RESULTS: In total, 123 patients were evaluated. A small reduction in EF was observed after chemotherapy in both chemotherapy groups. There were no significant differences between groups A and A+T in EF decline following chemotherapy. We could not find any differences in composite risk between the chemotherapy groups and the RT group during follow-up. Late cardiotoxicity was seen in 15.45% of patients. During follow-up, three patients were diagnosed with dilated cardiomyopathy.CONCLUSION: There was no significant composite risk elevation following adjuvant treatment of breast cancer. However, late cardiotoxicity was considerable and further research in this direction is necessary.
