BACKGROUND The totally implantable venous access port(TIVAP)is an important device in patients for injecting blood products,parenteral nutrition or antineoplastic chemotherapy.Metastatic spread at the site of the insertion of a TIVAP is extremely rare.CASE SUMMARY We report the case of 33-year-old male with advanced gastrointestinal stromal tumor(GIST)who underwent radical tumor resection after neoadjuvant imatinib therapy.However,a solitary GIST metastasis at the site of a TIVAP insertion developed during adjuvant imatinib treatment.Mutational analysis showed secondary mutation in KIT exon 13(V564 A),which is resistant to imatinib treatment.To our knowledge,this is the first case report of a patient with advanced GIST developing GIST metastasis at the site of a TIVAP insertion.CONCLUSION This case highlights that when a patient with advanced,high metastatic GIST requires TIVAP insertion,we should realize that there is a risk of developing tumor metastasis at the site of a TIVAP insertion. 展开更多

BACKGROUND Venous variations are uncommon and usually hard to identify,and basilic vein variation is particularly rare.Basilic vein variation usually presents without any clinical symptoms and is often regarded as a benign alteration.This case was a patient with congenital basilic vein variation encountered during surgery for an infusion port.CASE SUMMARY We documented and analyzed an uncommon anatomical variation in the basilic vein encountered during arm port insertion.This peculiarity has hitherto remained undescribed in the literature.We offer remedial strategies for addressing this anomaly in the future and precautionary measures to circumvent its occurrence.We conducted a comprehensive review of analogous cases in the literature,offering pertinent therapeutic recommendations and solutions,with the aim of enhancing the efficacy and safety of future arm port implantations.CONCLUSION Venous variation is rare and requires detailed intraoperative and postoperative examination to ensure accuracy,so as not to affect subsequent treatment. 展开更多

Background: As the prognosis of lung cancer (LC) patients improves, subcutaneously implanted central venous access device ports (CV-ports) have frequently been used for continuing chemotherapy (CC) or palliative care (PC). In this study, we examined the clinical course of LC patients with subcutaneously implanted CV-ports from the time of receiving chemotherapy to the endpoint of cancer. Materials and Methods: We retrospectively reviewed the clinical data and treatment history of LC patients with subcutaneously implanted CV-ports between June 2008 and November 2013 using clinical records and a pharmacy database. Results: Of the 132 LC patients with subcutaneously implanted CV-ports, 79 (59.8%) had CV-ports for CC (the CC group) and 53 (40.2%) had CV-ports for PC (the PC group). After CV-port implantation, LC patients in the CC group received a median of two regimens with a median of 6 cycles. The median survival time of patients in the CC and PC groups was 457 and 44 days, respectively. In the CC group, the median survival time of small cell and non-small cell LC patients was 342 (95% confidence interval, 235 - 627) and 563 (95% confidence interval, 368 - 728) days, respectively. Nine patients (6.8%) had their CV-ports removed due to complications. Forty (30.3%) of the 132 enrolled patients were referred for at-home PC. The at-home death rate observed among these 40 patients was 30.0% (N = 12). Conclusion: CV-ports may contribute to seamless oncological care. 展开更多

BACKGROUND Breast cancer poses a great threat to females worldwide.There are various therapies available to cure this common disease,such as surgery,chemotherapy,radiotherapy,and immunotherapy.Implantable venous access ports(IVAP,referred to as PORT)have been widely used for breast cancer chemotherapy.Venous malformations are possible conditions encountered during PORT implantation.Persistent left superior vena cava(PLSVC)is a common superior vena cava malformation.Most patients have normal right superior vena cava without affecting hemodynamics,so patients often have no obvious symptoms.CASE SUMMARY We incidentally found that two patients had PLSVC while a PORT was implanted via the internal jugular vein.Due to chemotherapy for breast cancer,PORT was successfully implanted under the guidance of ultrasound into these 2 patients.Positive chest X-ray examination after the operation showed that the catheter ran beside the left mediastinum and the end was located in the seventh thoracic vertebra.The patients had no catheter-related complications and successfully completed the course of chemotherapy.Ultrasonography found that the ratio of PORT outer diameter to PLSVC inner diameter was less than 0.45,which was in line with the recommendations of relevant literature and operating guidelines.The purpose of this article is to introduce two rare cases and review the relevant literature.CONCLUSION Correct assessment of PLSVC status and ultrasound-guided PORT placement generally does not affect breast cancer patients chemotherapy. 展开更多
