Severity of disease and treatment outcomes of anterior accessory great saphenous veins compared with the great saphenous vein.

OBJECTIVE: Endovenous therapies are currently the standard of care for the treatment of patients with symptomatic great saphenous vein (GSV) reflux. The effectiveness and long-term outcomes of these therapies for anterior accessory great saphenous veins (AAGSVs) are poorly defined. The objective of this investigation is to determine treatment outcomes in patients with symptomatic AAGSV reflux compared with patients with symptomatic GSV reflux. METHODS: Data were prospectively collected in the Center for Vein Restoration's electronic medical record system (NexGen Healthcare Information System, Irvine, Calif) and retrospectively analyzed. Treatment outcomes after a standalone ablation and ablation + phlebectomy were compared in patients with isolated AAGSV and GSV reflux. Treatment outcomes were assessed at 1 month and 6 months postprocedure using the revised Venous Clinical Severity Score (rVCSS) and the 20-item Chronic Venous Insufficiency Quality-of-Life Questionnaire (CIVIQ20) survey for quality of life. Medical and surgical comorbidities, Clinical-Etiological-Anatomical-Pathophysiological classification, body mass index, gender, race, and the average number of procedures performed were all analyzed. RESULTS: From January 2015 to December 2018, 31,186 patients and 49,193 limbs were assessed. Of these, 91 patients/103 limbs had isolated AAGSV reflux, and 7704 patients/10,371 limbs had isolated GSV reflux. There were 95% and 75% women in the isolated AAGSV and GSV groups, respectively (P ≤ .001). For the ablation-only patients, AAGSV (n = 57 patients/61 limbs) and GSV (n = 5349 patients/7191 limbs), there were no differences in preintervention (7.0 ± 2.0 vs 6.8 ± 2.8, P = .99), 1-month (4.0 ± 2.4 vs 3.9 ± 2.8, P = .99), and 6-month (3.9 ± 2.6 vs 3.9 ± 2.9, P = .55) rVCSS scores. Similar results were observed when ablations and phlebectomies were performed (AAGSV [n = 34 patients/42 limbs] and GSV [n = 1848 patients/2491 limbs]). CIVIQ20 scores for patients with isolated AAGSV and GSV were 53.3 ± 19.6 vs 50.6 ± 18.8 (P = .43) preintervention, 37.2 ± 17.6 vs 35.7 ± 15.9 (P = .91) at 1 month, and 41.3 ± 21.7 vs 35.1 ± 15.7 (P = .36) at 6 months, respectively. Postprocedure scores within groups improved at 1 and 6 months (P ≤ .02); however, 6-month AAGSV CIVIQ20 scores after an ablation increased slightly compared with 1-month scores and were not different to preintervention GSV scores (P = .07). When phlebectomies were performed with ablations, 6-month CIVIQ20 scores were similar between groups (P = .72). There was no difference in the average number of ablations in patients with phlebectomies in the AAGSV or GSV group (1.24 ± 0.44 vs 1.35 ± 0.49, P = .15). CONCLUSIONS: Endovenous therapies for the treatment of symptomatic AAGSVs demonstrate similar outcomes to patients with symptomatic GSV reflux. For standalone ablations, the rVCSS scores are similar between the groups; however, CIVIQ20 scores increase to preintervention levels in standalone ablation AAGSV patients at 6 months. This increase disappears when phlebectomies are performed with ablations. Based on these data, patients with symptomatic AAGSV treated with ablation also require treatment of the associated tributaries (varicosities) to achieve similar outcomes to patients with GSV, and this calls into question the effectiveness of ablation for isolated AAGSV reflux.

Pregnancy after iliac vein stenting for pelvic venous insufficiency.

BACKGROUND: The use of iliac vein stenting for the treatment of pelvic pain secondary to pelvic venous insufficiency has significantly increased. In women of childbearing age, the effect of the gravid uterus on stent function and patency is unclear. The purpose of this investigation was to determine the effect of pregnancy on stent patency and reintervention rate in women with iliac vein stents. METHODS: A retrospective chart review and email survey was performed to identify women treated at the Center for Vascular Medicine who were treated with iliac vein stenting and who had subsequent pregnancies. Medical and surgical comorbidities, stent type, location, length, number of stents, reintervention rates, number of pregnancies after stenting, anticoagulation usage during pregnancy, and type of delivery were assessed. RESULTS: From January 2014 to December 2020, 15 women with 16 iliac vein stents and who had 17 subsequent pregnancies were identified. The average age at stenting was 35.3 ± 4.13 years. The average interval between stenting and conception was 350 ± 287 days. Before pregnancy, stent location was in the right common/right external iliac veins in 1 patient and left common/external iliac veins in 14 patients. The average stent diameter and length were 19.6 ± 3 and 79.5 ± 20.3 mm, respectively. Thirteen Boston Scientific Wallstents and three Bard Venovo stents were used before pregnancy. One patient with a Wallstent required a stent extension before pregnancy and one patient had two stents placed at the initial procedure. Two women were pregnant twice after stenting for a total of 17 pregnancies. There were 16 term and 1 premature delivery of single infants. Patients were treated with enoxaparin (Lovenox) for stent-related thrombosis prophylaxis in 11 of 17 pregnancies, 5 had no prophylaxis, and the status of 1 pregnancy is unknown. One asymptomatic patient underwent a stent venoplasty after delivery. CONCLUSIONS: Iliac vein stents tolerate a gravid uterus well. No stents thrombosed during or after pregnancy and none required reintervention secondary to pregnancy-related compression. Anticoagulation with low-molecular-weight heparin should be considered for stent thrombosis prophylaxis. Potential pregnancy should not be considered a contraindication to iliac vein stenting for the treatment of symptomatic pelvic venous insufficiency.

Effect of obesity on chronic venous insufficiency treatment outcomes.

BACKGROUND: Obesity is a known risk factor for the development and progression of chronic venous disorders (CVDs). It is currently unknown whether the treatment outcomes, after an intervention for CVDs, are affected by obesity. The purpose of the present investigation was to assess the effectiveness of various CVD treatments in obese patients and determine what level of obesity is associated with poor outcomes. METHODS: Data were prospectively collected in the Center for Vein Restoration electronic medical record system (NexGen Healthcare Information System, Irvine, Calif) and retrospectively analyzed. The patients and limbs were categorized by the following body mass index (BMI) categories: <25, 26 to 30, 31 to 35, 36 to 40, 41 to 45, and >46 kg/m2. The changes in the revised venous clinical severity score and Chronic Venous Insufficiency Quality of Life Questionnaire 20-item (CIVIQ-20) quality of life survey were used to determine the CVD treatment effectiveness for patients who had undergone endovenous thermal ablation (TA), phlebectomy, or ultrasound-guided foam sclerotherapy (USGFS). RESULTS: From January 2015 to December 2017, 65,329 patients (77% female; 23% male) had undergone a venous procedure. Of these patients, 25,592 (39,919 limbs) had undergone ablation alone, ablation with phlebectomy, or ablation with phlebectomy and USGFS. The number of procedures performed was as follows: TA, n = 37,781; USGFS, n = 22,964; and phlebectomy, n = 17,467. The degree of improvement at 6 months after the procedure was progressively less with an increasing BMI for the patients who had undergone TA, and the decrease was more significant for those patients with a BMI >35 kg/m2 (P ≤ .001). The outcomes improved ∼12% with the addition of phlebectomy to TA. The patients who had undergone a combination of TA, phlebectomy, and USGFS demonstrated no additional improvement. Significantly inferior outcomes were noted in patients with a BMI ≥35 kg/m2, with the poorest outcomes observed in patients with a BMI ≥46 kg/m2 (P ≤ .001). The average number of TAs per patient increased with an increasing BMI and was significantly different compared with the number for those with a BMI <30 kg/m2 (P ≤ .001). All pre- and post-CIVIQ-20 quality of life scores, within a BMI category, at 6 months were significantly different (P ≤ .01). No differences in the degree of improvement were observed in patients with a BMI ≥31 kg/m2. Finally, multivariate logistic regression analysis indicated that when controlling for BMI, diabetes, a history of cancer, female gender, and black and Hispanic race were independently associated with poorer outcomes. CONCLUSIONS: Progressive increases in BMI negatively affected CVD-related treatment outcomes as measured using the revised venous clinical severity score and CIVIQ-20. The outcomes progressively worsened with a BMI >35 kg/m2 for patients undergoing CVD treatment. The treatment outcomes for patients with a BMI ≥46 kg/m2 were so poor that weight loss management should be considered before offering CVD treatment.

Solitary hepatic gastrinoma treated with laparoscopic radiofrequency ablation.

BACKGROUND: This is a case of a solitary hepatic gastrinoma in a 65-year-old male. The patient was diagnosed with Zollinger-Ellison syndrome in 1991. He had negative radiologic and surgical explorations at that time. He was maintained on proton-pump inhibitors for the next 10 years without symptoms. METHODS: A computed tomographic (CT) scan done in April 2001 demonstrated a 5-cm right hepatic lesion. Radionucleotide scanning with octreotide demonstrated intense activity in the same area in the right hepatic lobe. His serum gastrin was 317 pg/mL. He underwent laparoscopic radiofrequency ablation of the lesion. RESULTS: Treatment resulted in a 6-cm ablative area giving a 1-cm margin on the tumor. One- and 3-month follow-up CT scans demonstrated adequate ablation of the tumor. An octreotide scan done 3 months postoperatively did not reveal any areas of abnormal uptake. CONCLUSION: We report success with laparoscopic radiofrequency ablation as an alternative to major hepatic resection in patients with a solitary hepatic gastrinoma.

Laparoscopic parastomal hernia repair.

Historically, parastomal hernias have represented a challenge to surgeons. Unsatisfying results from surgical repair have led to many modifications over time. Surgical repair of parastomal hernias has evolved from the traditional open technique to the current laparoscopic approach. We outline a technique that combines mesh reinforcement with a minimally invasive approach.
