Additional Value

SummaryThe objectives of this observational study were to investigate whether varicography has additional value to CFDI in clarifying the nature and source of recurrent varicose veins below the knee after varicose vein surgery and to investigate the possible role of incompetent perforating veins (IPV) in these recurrent varicose veins. Patients, material, methods: 24 limbs (21 patients) were included. All patients were assessed by a preoperative clinical examination and CFDI (colour flow duplex imaging). Re-evaluation (clinical and CFDI) was done two years after surgery and varicography was performed. Primary endpoint of the study was the varicographic pattern of these visible varicose veins. Secondary endpoint was the connection between these varicose veins and incompetent perforating veins. Results: In 18 limbs (75%) the varicose veins were part of a network, in six limbs (25%) the varicose vein appeared to be a solitary vein. In three limbs (12.5%) an incompetent sapheno-femoral junction was found on CFDI and on varicography in the same patients. In 10 limbs (41%) the varicose veins showed a connection with the persistent below knee GSV on varicography. In nine of these 10 limbs CFDI also showed reflux of this below knee GSV. In four limbs (16%) the varicose veins showed a connection with the small saphenous vein (SSV). In three limbs this reflux was dtected with CFDI after surgery. An IPV was found to be the proximal point of the varicose vein in six limbs (25%) and half of these IPV were detected with CFDI as well. Conclusion: Varicography has less value than CFDI in detecting the source of reflux in patients with recurrent varicose veins after surgery, except in a few cases where IPV are suspected to play a role and CFDI is unable to detect these IPV.

AbstractHepatic cancer is often amenable to surgery, including percutaneous ablation, trans-arterial chemoembolization. However, in metastatic cases, surgery is often not an effective option. Chemotherapy as a conventional clinical method for treatment of malignant diseases may be useful in such cases, but it is likewise not always able to slow or halt progression, therefore novel approaches for treatment of hepatic cancer are needed. Current research suggests that molecular tumor markers (TM) can play a crucial role for diagnosis and prognostic evaluation of malignancies, and TM such as AFP, CEA, CA19-9 have been reported in many malignant diseases. Thioredoxin reductase (TrxR), a type of anti-oxidant biomarker, has become a TM of significant interest. However, little is known about the above TM and TrxR activity in liver cancer. Therefore, this paper aimed to assess these TM with regards to diagnosis and and monitoring treatment efficacy in both primary and metastatic liver cancer. Our results showed TrxR had superior performance for discriminating between liver cancer patients and healthy controls than AFP, CEA, and CA19-9. TrxR also exhibited superior performance for assessing benefits of chemotherapy regardless if patients had PLC or MLC. Meanwhile, due to diagnostic efficiency of unresponsive chemotherapy patients, TrxR also showed a higher activity levels than other general markers in liver metastasis patients. Our results suggest that application of TrxR in combination with other tumor markers may maximize the efficiency of diagnosis and assessment of therapeutic efficiency, and provide new insights for the clinical application of TrxR as a candidate biomarker for liver cancer.
