A multi-institutional review of endovenous thermal ablation of the saphenous vein finds male sex and use of anticoagulation are predictors of long-term failure.

BACKGROUND: To review long-term outcomes and saphenous vein (SV) occlusion rate after endovenous ablation (EVA) for symptomatic varicose veins. METHODS: A review of our EVA database (1998-2018) with at least 3-years of clinical and sonographic follow-up. The primary end point was SV closure rate. RESULTS: 542 limbs were evaluated. 358 limbs had radiofrequency and 323 limbs had laser ablations; 542 great saphenous veins (GSV), 106 small saphenous veins (SSV) and 33 anterior accessory saphenous veins (AASV) were treated. Follow-up was 5.6 ± 2.3 years; 508 (74.6%) veins were occluded, 53 (7.8%) partially occluded and 120 (17.6%) were patent. On multivariable Cox regression analysis, male sex (HR 1.6, 95% CI [0.46-018], p = 0.012) and use anticoagulation (HR 2.0, 95% CI [0.69-0.34], p = 0.044) were predictors of long-term failure. On Kaplan-Meier curve, we had an 86.3% occlusion rate. CONCLUSION: Our experience revealed a 5-year closure rate of 86.3%. Ablations have satisfactory occlusion rate.

Hybrid Open-Endovascular Repair in a Patient With Giant Contained Aortic Aneurysm Rupture.

Contained rupture of an aortic aneurysm is a high-mortality condition that requires immediate repair. Open repair has been the gold standard; however, endovascular and hybrid open-endovascular repair techniques have also emerged as less invasive solutions to this vascular emergency. Here. we present a patient with a giant 14.0 cm contained rupture of a Thoracic aortic aneurysm and 7.4 cm juxtarenal abdominal aortic aneurysm who was successfully treated with hybrid open-endovascular repair.

Elevated Soluble Galectin-3 as a Marker of Chemotherapy Efficacy in Breast Cancer Patients: A Prospective Study.

PURPOSE: Galectin-3 (Gal-3) is a glycan-binding lectin with a debated role in cancer progression due to its various functions and patterns of expression. The current study investigates the relationship between breast cancer prognosis and secreted Gal-3. METHODS: Breast cancer patients with first time cancer diagnosis and no prior treatment (n = 88) were placed in either adjuvant or neoadjuvant setting based on their treatment modality. Stromal and plasma Gal-3 levels were measured in each patient at the time of diagnosis and then throughout treatment using immunohistochemistry (IHC) and ELISA, respectively. Healthy women (>18 years of age, n = 63) were used to establish baseline levels of plasma Gal-3. Patients were followed for 84 months for disease-free survival analysis. RESULTS: Enhanced levels of plasma (adjuvant) and stromal (neoadjuvant) Gal-3 were found to be markers of chemotherapy efficacy. The patients with chemotherapy-induced increase in extracellular Gal-3 had longer disease-free interval and significantly lower rate of recurrence during 84-month follow-up compared to patients with unchanged or decreased secretion. CONCLUSION: The findings support the use of plasma Gal-3 as a marker for chemotherapy efficacy when no residual tumor is visible through imaging. Furthermore, stromal levels in any remaining tumors postchemotherapy can also be used to predict long-term prognosis in patients.

Results of surgical resection of carotid body tumors: A twenty-year experience.

This study examines whether surgical resection of carotid body tumors (CBTs) is acceptable in light of potential significant neurologic complications. This IRB-approved retrospective study analyzed data from 24 patients undergoing surgical treatment for CBTs between April 1998 and April 2017 at Mayo Clinic (Florida campus only). For patients who underwent multiple CBT resections, only data from the first surgery was used in this analysis. CBT resection occurred in 24 patients with the following demographics: fourteen patients (58.3%) were female, median age was 56.5 years, median BMI was 29. A prior history of neoplasm was found in ten patients (41.7%). A known family history of paraganglioma was present in five patients (20.8%). Two patients were positive for succinate dehydrogenase mutation (8.3%). Multiple paragangliomas were present in seven patients (29.2%). There was nerve sacrifice in three patients (12.5%) during resection. Carotid artery reconstruction and patch angioplasty occurred in one patient (4.2%). Complete resection occurred in 24 patients (100.0%). Postoperatively, one patient (4.2%) suffered stroke. No mortalities occurred within or beyond 30 days of surgery. Persistent cranial nerve injury occurred in two patients (8.3%) with vocal cord paralysis. There was no recurrence of CBT through last follow-up. Five patients (20.8%) were diagnosed with other neoplasms after resection, including basal cell carcinoma, contralateral carotid body tumor, glomus vagale, and glomus jugulare. There was 100% survival at 1 year in patients followed for that time (n = 17). Surgical treatment remains the first-line curative treatment to relieve symptoms and ensure non-recurrence. While acceptable, neurologic complications are significant and therefore detailed preoperative informed consent is mandatory.

Complex management of acute superior mesenteric venous thrombosis in the setting of metastatic ovarian cancer.

•Superior mesenteric vein thrombosis (SMVT) is rare but seen in patients with hypercoagulable states.•Prevention of mortality in patients with SMVT requires immediate diagnosis and complex management.•A hierarchical approach to treatment progresses to more aggressive treatment as needed.•Supportive care, medication, and endovascular and/or surgical interventions are available management options.•In patients with underlying conditions, long-term treatment such as anticoagulation must also be initiated.

Clinical Assessment of a Biofilm-disrupting Agent for the Management of Chronic Wounds Compared With Standard of Care: A Therapeutic Approach.

OBJECTIVE: The authors study the use of a biofilm-disrupting wound gel designed for wound management to determine if disrupting chronic wound biofilm would be therapeutically efficacious. MATERIALS AND METHODS: This prospective, randomized, open-label clinical trial was performed from September 2014 through March 2016. Forty-three patients (22 experimental, 21 control) with chronic, recalcitrant wounds were randomized to a 12-week treatment with a biofilm-disrupting wound gel (experimental) or a broad-spectrum antimicrobial ointment (control). The wound healing rate was assessed by measuring wound size reduction and wound closure rates. RESULTS: Wound size in the experimental group decreased significantly with a 71% reduction in wound area compared with 24% for the control (P < .001). Wound closure was attained in more than half of the patients (14) treated with the experimental product. Fifty-three percent of these patients achieved closure by 12 weeks as opposed to 17% for the control (P < .01). No adverse events related to the experimental product were recorded, but 2 adverse reactions occurred with the control. CONCLUSIONS: The combination of the experimental product and wound debridement significantly improved wound healing rates by disrupting the biofilm, which protects multispecies bacteria within a chronic wound. Given the significant wound size reduction and closure rates observed in these long-term, nonhealing wounds, as well as the lack of related serious adverse events, the investigators believe the biofilm-disrupting wound gel to be a safe and effective treatment for recalcitrant chronic wounds.
