Sequential percutaneous tricuspid and pulmonary valve implantation in a young child operated previously for Ebstein Anomaly.

We report a successful percutaneous tricuspid valve implantation followed by a percutaneous pulmonary valve implantation in a young child with Ebstein's anomaly of tricuspid valve and pulmonary stenosis who was previously treated surgically at 1 year of age with tricuspid ring annuloplasty and a transannular outflow patch. This article shows the feasibility of sequential implantation of two valves in young patients with severe tricuspid and pulmonary valve insufficiency.

Outcomes of Extracorporeal Membrane Oxygenation in Patients After Repair of Congenital Heart Defects.

Extracorporeal membrane oxygenation (ECMO) is widely used after congenital heart surgery. The purpose of this study is to analyze the factors influencing mortality and morbidity in patients who require ECMO support after congenital cardiac surgery. All 109 patients (5.8% of total cases) who underwent ECMO support after congenital heart surgery between January 2014 and 2021 were included in this single-center study. The mean age was 10.13 ± 20.55 months, and the mean weight was 6.41 ± 6.79 kg. 87 (79.8%) of the patients were under 1 year of age. A total of 54 patients (49.5%) were weaned successfully from ECMO support, and 27 of them (24.8%) were discharged. The childhood age group had the best outcomes. Seventy-seven percent of the children were weaned successfully, and 50% were discharged. 69 patients (63.3%) had biventricular physiology; weaning and survival outcomes were better than single ventricle patients (P-value 0.002 and < 0.001, respectively). Low cardiac output (n = 49; 44.9%) as an ECMO indication had better outcomes than extracorporeal cardiopulmonary resuscitation (n = 31; 28.4%) (P = 0.05). Most of the patients had ≥ 4 Modified Aristotle Comprehensive Complexity (MACC) levels, and higher MACC levels were associated with a higher mortality rate. The most common procedure was the Norwood operation (16.5%), with the worst outcome (5.5% survival). Bleeding and renal complications were the most common complications affecting outcomes. Results were more satisfactory in patients with biventricular repair, childhood, and lower MACC levels. Early initiation of ECMO in borderline patients without experiencing cardiac arrest or multiorgan failure may improve outcomes.

Analysis of outcomes in patients with abnormal laterality undergoing congenital heart surgery.

OBJECTIVE: Laterality anomalies are almost always associated with severe cardiac anomalies. Demographic properties, type of the procedures, associated anomalies, and early and mid-term prognosis of four types of laterality anomalies were analysed. METHODS: A total of 64 consecutive patients with laterality anomalies were enrolled between July 2014 and July 2020. We grouped the patients as situs solitus dextrocardia (SSD) (n = 12; 18.7%); situs inversus (SI) (n = 16; 25%); right atrial isomerism (RAI) (n = 29; 45.3%); and left atrial isomerism (LAI) (n = 7; 10.9%). TAPVC was only present in the RAI group (31%). Incidence of mitral or tricuspid atresia was higher in the SSD group (25%). All the patients were followed up with a mean of 19.06 ± 17.6 (0.1-72) months. RESULTS: Early postoperative mortality was 17 patients, among 107 procedures (15.8%). Twelve patients were in the neonatal period. All ten patients survived after isolated ductal stenting. Fourteen of the deaths were in the RAI group (48.3%). The 3-year survival rates were 85% in LAI, 78.7% in SI, 55.8% in SSD, and 38% in RAI groups. According to the multivariable Cox regression model, mechanical ventilation, kidney injury, RAI, and complex surgery in the neonatal period were independent risk factors for early mortality. CONCLUSION: Laterality anomalies are one of the most challenging patients who commonly had univentricular physiology. The most prevalent anomaly was RAI, and RAI had the worst outcome and survival. Ductal stent is an acceptable first intervention during the neonatal period in suitable patients. Complex procedures may carry a high risk of death in the neonatal period.

Does a prenatal diagnosis affect mortality and morbidity for neonatal arterial switch operation.

BACKGROUND: The effect of prenatal diagnosis on prognosis in patients with transposition of the great arteries is not clear. In this study, we compared the outcomes after arterial switch operation. METHODS: Outcome of 112 patients who had arterial switch operation in the neonatal period were analysed. The patients were divided into two groups: those who had prenatal diagnosis (Group 1; n = 34) and those who did not (Group 2; n = 78). The patients were also classified based on their diagnosis: simple transposition, transposition with ventricular septal defect and/or aortic arch hypoplasia, and Taussig-Bing anomaly. RESULTS: In Group 1, the C-section delivery rate was higher (82% vs. 44%; p = 0.004), and it was observed that patients in Group 1 were more often intubated upon admission to the neonatal ICU (38% vs. 9%; p = 0.005). No differences were found between the two groups in terms of operation time, cardiopulmonary bypass time, post-operative invasive respiratory support duration, or extracorporeal membrane oxygenation support. It was observed that those who had Taussig-Bing anomaly had a higher mortality. CONCLUSIONS: Timely treatment have a positive effect on neonatal mortality and morbidity. That's why all families with prenatal diagnosis of critical CHD should be recommended to have the delivery in a tertiary care hospital. Although it could not be demonstrated in this study, prenatal diagnosis has a potential to improve surgical results especially in countries or cities, which does not have enough resources for transfer and surgical units. Further efforts are needed to improve prenatal screening programmes.

Evaluation of neonatal acute kidney injury after critical congenital heart disease surgery.

BACKGROUND: Acute kidney injury (AKI) is a common complication of congenital heart diseases (CHDs) after cardiac surgery. This study aimed to define the frequency and critical course, risk factors and short-term outcomes of AKI in postoperative CHD neonates. METHODS: Postoperatively followed term CHD newborn infants were enrolled in the study. Infants with congenital anomalies of the urinary tract and other major congenital anomalies were excluded. Neonatal modified KDIGO criteria were used to assess AKI. RESULTS: A total of 199 postoperatively followed newborn infants were included in the study. Acute kidney injury was detected in 71 (35.6%) patients. Of these patients, 24 (33.8%) were in stage 1, 14 (19.7%) in stage 2, and 33 (46.5%) in stage 3. Acute kidney injury occurred within the first week (median 1 day [IQR 1-2 days]) of cardiac surgery in 93% of the patients. The duration of invasive respiratory support and extracorporeal membrane oxygenation (ECMO) and mortality were significantly higher in stage 3 patients. Higher vasoactive-inotropic score (OR, 1.02; 95% CI, 1.0-1.04; p = 0.008) and receiving ECMO (OR, 7.9; 95% CI, 2.6-24.4; p = 0.001) were associated with risk for the development of AKI. The mortality rate was 52.1% in the AKI (+) patients, and having AKI (OR 7.1; 95% CI, 3.5-14.18) was significantly associated with mortality. CONCLUSION: Acute kidney injury, a common early complication after critical neonatal CHD cardiac surgery, is associated with increased morbidity and mortality. Stage 3 AKI is associated with significantly higher mortality rates.

Management of aortic arch hypoplasia in neonates and infants.

OBJECTIVES: Surgical management of aortic arch hypoplasia (AAH) with associated intracardiac anomalies is a challenge in newborns. We reviewed the characteristics and outcomes of neonates and infants who underwent pulmonary artery banding concomitant to arch repair and single-stage total repair at our institution. METHODS: Medical records of 60 patients undergoing aortic arch reconstruction for AAH from 2014 to 2019 were retrospectively reviewed. Twenty-five patients were female (41.6%), and the age of the patients ranged from 4 to 120 days (median, 19.5 days). The patients were divided into two groups: Group 1 (23 patients) underwent pulmonary artery banding concomitant to arch repair, and Group 2 (37 patients) underwent single-stage total repair in addition to arch repair. All arch repair procedures consisted of an extended (to the midportion of the ascending aorta) patch aortoplasty. RESULTS: Postoperative early mortality occurred in 12 patients, eight in Group 1 (34.8%) and four in Group 2 (10.8%). There was an early survival advantage in Group 2 (p = .019). Recoarctation occurred in 13 cases (21.6%), and 11 (18.3%) of them required reintervention (balloon angioplasty: 7, reoperation: 4). On univariate analysis, risk factors associated with death were pulmonary artery banding (hazard ratio [HR], 0.44; confidence interval [CI], 0.09-2; p = .019), prematurity (HR, 4.67; CI, 1.34-16.18; p = <.001), preoperative mechanical ventilation support requirement (HR, 0.048; CI, 0.52-6.39; p = .048), and functional single ventricle (HR, 0.43; CI, 0.1-1.86; p = .006). The mean duration of follow-up was 21.9 ± 15.1 months, and there was no late death in either group. CONCLUSION: Single-stage repair of AAH with intracardiac pathologies has better results than palliation, according to survival rates and postoperative results. The use of the patch augmentation technique in AAH is valid and associated with an acceptable incidence of recurrent arch obstruction.

Comparison of different pulmonary valve reconstruction techniques during transannular repair of tetralogy of fallot.

BACKGROUND: Transannular patch, which results in pulmonary insufficiency (PI), is usually required during repair of tetralogy of fallot (TOF). In this study, we compared three types of pulmonary valve reconstruction techniques during transannular repair of TOF. METHODS: Between February 2014 and January 2018, 50 patients with TOF underwent primary repair with transannular patch. These patients were divided into three groups. In Group 1, (n = 15), a single gluteraldehyde-treated autologous pericardial patch (standard method) was reconstructed as monocusp. In Group 2, (n = 16) Nunn's bileaflet pulmonary valve reconstruction technique was used with pericardial patch. In Group 3, (n = 19), Nunn's bileaflet technique was performed with expanded polytetrafluoroethylene membrane. The outcomes of the patients and early and midterm competency of the pulmonary valves were analyzed. RESULTS: These techniques were significantly effective in early postoperative period. Freedom from moderate to severe PI were 73.3%; 100% and 89.4%, respectively. Mortality, duration of intensive care unit and hospital stay were similar between the groups. The mean follow-up period was 17.5 ± 13.0 (3-57) months. Freedom from moderate to severe PI decreased to 40%; 81.2% and 73.7%, respectively at the end of the follow-up period. Presence of moderate to severe PI was significantly higher in Group 1 (p = .018 between Groups 1 and 2, p = .048 between Groups 1 and 3). CONCLUSION: All three pulmonary valve reconstruction techniques provided competent pulmonary valves. Nunn's bileaflet technique had better outcome at midterm. It has a potential to delay right ventricular dysfunction at long-term.

Outcomes of home mechanical ventilation with tracheostomy after congenital heart surgery.

OBJECTIVE: After congenital heart surgery, some patients may need long-term mechanical ventilation because of chronic respiratory failure. In this study, we analysed outcomes of the patients who need tracheostomy and home mechanical ventilation. METHODS: Amongst 1343 patients who underwent congenital heart surgery between January, 2014 and June, 2018, 45 needed tracheostomy and HMV. The median age of these patients was 6.4 months (12 days-6.5 years). Nineteen patients underwent palliation while 26 patients underwent total repair. Post-operative diaphragm plication was performed in five patients (11%). Median duration of mechanical ventilation before tracheostomy was 32 days (8-154 days). The patients were followed up with their home ventilators in ward and at home. Mean follow-up time was 36.24 ± 11.61 months. RESULTS: The median duration of ICU stay after tracheostomy was 27 days (range 2-93 days). Follow-up time in ward was median 30 days (2-156 days). A total of 12 patients (26.6%) were separated from the ventilator and underwent decannulation during hospital stay. Thirty-two patients (71.1%) were discharged home with home ventilator support. Of them, 15 patients (46.9%) were separated from the respiratory support in median of 6 weeks (1 week-11 months) and decannulations were performed. Total mortality was 31.1%. in which four patients are still HMV dependent. There was no significant difference for decannulation between total repair and palliation patients. CONCLUSION: HMV via tracheostomy is a useful option for the treatment of children who are dependent on long-term ventilation after congenital heart surgery although there are potential risks.

Early and midterm results of ductal stent implantation in neonates with ductal-dependent pulmonary circulation: a single-centre experience.

OBJECTIVE: We aimed to determine the early and midterm outcomes of ductal stenting in neonates with ductal-dependent pulmonary blood flow. METHODS: Between January, 2014 and July, 2018, 102 patients who underwent 115 cardiac catheterisation procedures for ductal stent implantation in our department were retrospectively reviewed. The age of the neonates ranged from 3 to 30 days (median: 11 days) and their weights ranged from 1.8 to 5.8 kg (mean, 2.8 ± 0.53 kg). Fifty-two patients had functional single ventricle and 50 had biventricular physiology. Thirty-one patients' weights were <2,500 g (30.3%). The patent ductus arteriosus was vertical in 60 patients (58.8%). The mean ductal length was 12.4 ± 4.1 mm (range, 7.8-23 mm), and the mean narrowest ductal diameter was 2.1 ± 0.7 mm (range, 1.2-3.4 mm). RESULTS: The technical success rate was 85.2%. Procedure-related mortality occurred in three patients (2.9%). After the procedure, the aortic oxygen saturation increased from a mean of 73.1 ± 6.2% to a mean of 90.4 ± 4.3% (p < 0.001), and the ductus diameter increased from a mean of 2.1 ± 0.7 mm to a mean of 4.2 ± 0.9 mm (p < 0.001). Either transcatheter or surgical reinterventions were required in 35 patients (34.3%) during the follow-up period after a median of 101 days (2-356 days). Thirty-three patients (32.3%) were bridged to surgical repair after a median of 288 days (163-650 days). The median duration of palliation with ductal stents was 210 days (range, 2-525 days). CONCLUSION: Ductus arteriosus stenting may be a reasonable and effective alternative to surgery for the initial palliation procedure in neonates with ductus-dependent pulmonary flow.

Right Atrial Flap Repair for Left Superior Vena Cava Draining into Left Atrium.

There are different surgical methods for the repair of persistent left superior vena cava that connects directly to the left atrium. We describe an extracardiac surgical technique that includes direct anastomosis of persistent left superior vena cava to the right atrium with right atrial flap and autologous pericardium. We have performed this procedure in four cases and there is no obstruction at postoperative control studies. Right atrial flap repair is a feasible extracardiac technique that offers growth potential.

Less painful tumescent solution for patients undergoing endovenous laser ablation of the saphenous vein.

BACKGROUND: This study aims to investigate the efficacy of lidocaine, prilocaine, and bupivacaine used in tumescent solution during endovenous laser treatment (EVLT) on intraoperative and postoperative pain. METHODS: This prospective randomized study included 90 patients. The patients were divided into 3 groups including 30 patients in each group, according to the content of local anesthetics in tumescent solution. All patients received EVLT treatment with lidocaine in group 1, prilocaine in group 2, and bupivacaine in group 3. Visual analog scale was used for the evaluation of intraoperative and postoperative pain. RESULTS: The mean intraoperative pain score was 2.27 ± 1.53 in group 1, 1.97 ± 1.54 in group 2, and 3.05 ± 0.73 in group 3. On the first day postoperatively, the mean pain score was 2.57 ± 1.7 in group 1, 3.27 ± 1.23 in group 2, and 1.13 ± 0.94 in group 3 (P = 0.0001). Intraoperative and postoperative mean pain scores during first day follow-up were significantly lower in group 3. CONCLUSIONS: Tumescent anesthesia is the most critical component of EVLT to improve comfort by reducing the pain. Therefore, we conclude that bupivacaine is an optimal alternative to lidocaine and prilocaine in tumescent anesthesia and can be used safely.

A comparison of three tumescent delivery systems in endovenous laser ablation of the great saphenous vein.

Different systems for delivering tumescent solution exist in endovenous laser ablation (EVLA). This study evaluated three different tumescent delivery systems in patients with primary varicose veins due to great saphenous vein reflux who were treated with EVLA. In this prospective non-randomized study, 60 patients with isolated GSV varicose veins were divided into three groups. All patients received EVLA treatment. Three different tumescent solution delivery systems were used. Systems consisted of a needle and a syringe in Group 1, a needle connected to an infusion bag system in Group 2 and a peristaltic infiltration pump in Group 3. Tumescent delivery durations were in Group 1: 6.56 SD 1.18 minutes, Group 2: 6.05 SD 2.19 minutes and Group 3: 5.19 SD 1.15 minutes (P = 0.014). In the outcomes of the study there were no significant difference between groups. Although peristaltic pump systems might provide shorter tumescent delivery durations without hand fatigue, shorter duration does not have any practical importance (about 1 minute and also it is not cost-effective. For delivering tumescent solutions in EVLA procedures, there was no major superiority between systems.

Case Report: Neo-ostium creation with saphenous vein in a patient with anomalous origin of the right coronary artery.

Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital anomaly. Most patients may be asymptomatic, but some may experience major cardiac events such as syncope, arrhythmias, and sudden cardiac death. We present a 16-year-old patient, who had several syncopes, with anomalous origin of the right coronary artery from the left coronary sinus, with an intramural and interarterial course between the pulmonary artery and the aorta. We describe a new surgical procedure of neo-ostium creation with a saphenous vein.

Carotid artery cut-down technique for ductus arteriosus stenting.

Background: This study aims to evaluate early and mid-term outcomes of ductal stenting via carotid artery surgical cut-down technique in neonates. Methods: Between January 2015 and January 2022, a total of 17 neonates (12 males, 5 females; median age: 14 days, range, 5 to 34 days) who underwent carotid artery surgical cut-down technique for ductal stenting were retrospectively analyzed. Diagnoses of the patients, demographics, procedural success/failure, access-related complications, and neuroimaging findings were recorded. Results: The primary indication for ductal stenting was pulmonary atresia in all patients. All patients who underwent carotid cut-down had vertical anatomy, with or without tortuous ductal anatomy, and they were not suitable for the femoral approach. The median body weight was 3 (range, 2 to 3.4) kg. Fifteen of the 17 interventions (88.2%) were successful. Two patients whose stenting failed underwent a systemic-to-pulmonary shunt operation. The early in-hospital mortality rate was 17.6% (n=3). No neurological or accessrelated complications were observed in any of the patients. Conclusion: Stenting the ductus arteriosus with challenging anatomy is feasible and safe with carotid artery cut-down, particularly in small neonates. Based on our study findings, this technique may offer an effective and less invasive alternative to the systemic-to-pulmonary shunt operation.

The effect of extracorporeal membrane oxygenation on neurodevelopmental outcomes in children after repair of congenital heart disease: A pilot study from Turkey.

Background: Extracorporeal membrane oxygenation (ECMO) is widely used after congenital heart surgery. The purpose of this study is to analyze the neurodevelopmental (ND) outcomes in patients who receivedECMO support after congenital cardiac surgery. Methods: Between January 2014 and January 2021, 111 patients (5.8%) receivedECMO support after congenital heart operations, and 29 (26,1%) of these patients were discharged. Fifteen patients who met the inclusion criteria were included. A propensity score matching (PSM) analysis model was established using eight variables (age, weight, sex, Modified Aristotle Comprehensive Complexityscores, seizures, cardiopulmonary bypass duration, number of operations, and repair method) with 1:1 matching. According to the PSM model, 15 patients who underwent congenital heart operations were selected as the non-ECMO group. The Ages & Stages Questionnaire Third Edition (ASQ-3) was used for ND screening;it includes communication, physical skills (gross and fine motor), problem-solving, and personal-social skills domains. Results: There were no statistically significant differences between the patients' preoperative and postoperative characteristics. All patients were followed up for a median of 29 months (9-56 months). The ASQ-3 results revealed that communication, fine motor, and personal-social skills assessments were not statistically different between the groups. Gross motor skills (40 vs. 60), problem-solving skills (40 vs. 50), and overall scores (200 vs. 250) were better in the non-ECMO patients (P = 0.01, P = 0.03, and P = 0.03, respectively). Nine patients (%60) in the ECMO group and 3 patients (%20) in the non-ECMO group were with neurodevelopmental delay (P = 0,03). Conclusion: ND delay may occur in congenital heart surgery patients who receivedECMO support. We recommend ND screening in all patients with congenital heart disease, especially those who receivedECMO support.

Successful Repair of Infantile Scimitar Syndrome with Contralateral Pulmonary Vein Stenosis in an Infant.

Infantile scimitar syndrome (SS) is a rare congenital heart disease and has high mortality. Guidelines have not been established, but surgery is indicated in symptomatic patients. Despite the various surgical approaches, outcomes continue to be disappointing. We present our surgical experience with an infantile SS patient who had stenotic pulmonary veins contralateral to the hypoplastic lung with complicated anatomy. There are few cases with this complex pathology in the literature. Moreover, our patient was the first transplant-free survivor with this complexity in the literature.

Toward Routine Minimally Invasive Ventricular Septal Defect Closure Via Right Lateral Minithoracotomy.

Background: Improving the surgical results and recent advancement of transcatheter techniques for closure of ventricular septal defect (VSD) increased the demand for minimally invasive approaches. In this study, we analyzed the results of the patients who underwent VSD closure with right lateral minithoracotomy (RLMT). Methods: Between September 2014 and February 2021, 24 patients underwent minimally invasive VSD closure with RLMT. The median age of the patients was 16 months (range, 4-84 months). Fifteen patients (62.5%) were female. The median weight of the patients was 9.75 kg (range, 4.6-30 kg). The types of VSD were perimembranous in 19 patients, subaortic in three patients, inlet in one patient, and subpulmonic in one patient. Five patients had low-lying pulmonary stenosis in addition to VSD. Results: No perioperative death or major complication occurred during follow-up. All defects were repaired through RLMT. The median cardiopulmonary bypass time was 81 min (range, 44-163 min), and the aortic cross-clamp time was 65 min (range, 33-131 min). The median hospital stay was 6 days (range, 5-21 days). One patient had minimal (2 mm) residual left-to-right shunt. All families were satisfied with the cosmetic results during the follow-up. Conclusions: The RLMT method is a safe and effective alternative to standard median sternotomy for VSD closure and can be performed with favorable cosmetic and clinical results.

Management of Interrupted Aortic Arch With Associated Anomalies: A Single-Center Experience.

OBJECTIVES: Interrupted aortic arch (IAA) includes a broad spectrum of associated anomalies. In this study, we present our surgical management and patient-specific decisions regarding IAA anomalies with early- and mid-term outcomes. METHODS: The medical records of 25 patients undergoing IAA repair between 2014 and 2019 were retrospectively reviewed. Sixteen patients had type B (64%) interruptions, 7 had type A (28%) interruptions, and 2 had type C (8%) interruptions. Fourteen patients had an isolated ventricular septal defect, and 3 of them had associated left ventricular outflow tract obstruction. Other associated anomalies were functional single ventricle (n = 5), Taussig-Bing anomaly (n = 3), aortopulmonary window (n = 1), multiple ventricular septal defects (n = 1), and truncus arteriosus with dextrocardia (n = 1). The initial operation age was 17.2 ± 14 (range: 1 - 60) days. RESULTS: Single-stage total repair was performed for 15 patients. Six patients underwent aortic arch repair and pulmonary artery banding. Four patients with left ventricular outflow tract obstruction or who were premature underwent the hybrid procedure. The aortic arch repair was performed in 16 cases (64%) by the anterior patch augmentation technique, in 3 cases (12%) by the reverse left subclavian artery flap technique, and in 3 cases (12%) by direct end-to-end anastomosis. Postoperative early mortality occurred in 4 (16%) patients, and sternal closure was delayed in 13 (52%) patients. Three patients who underwent a hybrid procedure due to left ventricular outflow tract obstruction underwent biventricular repair 8 to 13 months later. Eight patients (38%) required reintervention due to arch restenosis during the follow-up period. The mean follow-up was 37.1 ± 21.7 months. CONCLUSION: Planning surgical treatment according to the characteristics of the patients and accompanying anomalies may improve the results.

Endophlebectomy of the common femoral vein and endovascular iliac vein recanalization for chronic iliofemoral venous occlusion.

BACKGROUND: Chronic post-thrombotic occlusion of the iliofemoral veins causes significant morbidity, which can be alleviated if venous drainage is restored. We report our technique of surgical endophlebectomy and patchplasty of the common femoral vein (CFV) in conjunction with iliac vein stenting to restore venous flow from the infrainguinal venous system to the vena cava. METHODS: There were 157 patients who underwent CFV endophlebectomy combined with iliocaval recanalization. Questionnaires were completed both preoperatively and postoperatively to allow comparison. These included the Clinical, Etiology, Anatomy, and Pathophysiology clinical classification; the Venous Clinical Severity Score; the Villalta scale; the Venous Insufficiency Epidemiological and Economic Study on Quality of Life/Symptoms; and the 36-Item Short Form Health Survey quality of life questionnaire. RESULTS: Mean follow-up duration was 14.4 ± 2.9 months (range, 10-29 months). The mean preoperative Venous Clinical Severity Score was 15.3 ± 2.2, and this fell to 6.1 ± 1.8 after treatment (P < .001). The mean preoperative Villalta score dropped from 12.7 ± 2.6 to 6.3 ± 1.4 (P < .001). The quality of life and symptom severity scores were improved after 3 months by 17.2 points for quality of life (P < .001) and 20.5 points for symptom severity (P < .001). Primary patency was 81% (124/153) and secondary patency was 89.5% (137/153) at 12 months. Wound complications related to groin incision and lymphatic fistulas were observed in 22.8% (35/153) and 28.7% (44/153), respectively. CONCLUSIONS: The hybrid operation of CFV endophlebectomy in conjunction with iliac vein recanalization should be considered a safe and effective treatment option in patients with severe post-thrombotic syndrome and iliofemoral veno-occlusive disease.
