Item Management of Mechanical Problems of Totally Implantable Venous Catheters(MARMARA UNIV, INST HEALTH SCIENCES, 2020-01-01) Kara, Halil; Arikan, Akif Enes; Dulgeroglu, Onur; Uras, CihanObjective: Although the most common complications of totally implantable venous catheters(TIVC) are infection and thrombosis, mechanical complications can also affect the treatment and cause catheter removal. This study aimed to investigate mechanical complications of TIVC and prevention methods. Methods: Data of 983 procedures in 961patients who underwent TIVC implantation between 2010 and 2019 in AcibademMaslak, Bakirkoy, and Atakent Hospitals were retrospectively analyzed for mechanical complications. Results: Mechanical complications were encountered in 33(3.3\%) cases: 12(1.2\%) were detachment of TIVC, 8(0.8\%) occlusions, 5(0.5\%) pneumothorax, 1(0.1\%) hemothorax, 1(0.1\%) malposition, 1(0.1\%) extravasation, 2(0.2\%) TIVC rotation, 3(0.3\%) skin necrosis and extrusions. Conclusion: The catheter tip should be placed in distal superior vena cava, reservoir pocket must be sufficient in size, reservoir should be fixed to pectoral muscle or fascia at least two points with nonabsorbable sutures. Subcutaneous fatty tissue resection from reservoir pocket should be performed in obese patients. The nature of the withdrawn blood form Seldinger needle should be checked visually whether venous or not. Risk of pneumothorax and detachment can be reduced by inserting the catheter from 1/3 outer part of the clavicle during percutaneous technique. While complication rate can be reduced by peroperative fluoroscopy use, control X-ray should be taken in symptomatic patients, not routinely. Malposition can be seen in the peroperative period and can usually be corrected by good manipulation. Percutaneous transcatheter retrieval in addition to surgery is the gold standard treatment for detachment of TIVC. The most important factors in preventing complications are surgical experience and good care.Item Breast Surgery can be Performed Safely During the COVID-19 Pandemic: A Retrospective Single-Center Analysis(ISTANBUL TRAINING \& RESEARCH HOSPITAL, 2022-01-01) Arikan, Akif Enes; Kara, Halil; Dulgeroglu, Onur; Uras, CihanIntroduction: The Coronavirus disease-2019 (COVID-19) outbreak has affected the diagnosis and treatment of various diseases including breast cancer. This study aimed to investigate whether breast surgery can be performed safely during the COVID-19 pandemic. Methods: Patients who underwent surgery for breast cancer or suspicious breast lesions in the pre-pandemic, first wave, and second wave periods of the pandemic were evaluated retrospectively. Results: Data of 220 patients who underwent breast surgery were analyzed. No significant difference was found between the pre-pandemic, first wave, and second wave periods of the COVID-19 pandemic in terms of patient characteristics, complications, types of complication, Clavien-Dindo classification of complications, and complications requiring intervention. No COVID-19 related complication was also observed. Conclusion: Breast surgery can be performed safely in the COVID-19 pandemic. For safe surgery, appropriate precautionary measures against COVID-19 and COVID-19 screening should be initiated. COVID-19-free surgical pathway is also important for safe surgery. With the continuation of surgeries, fear of upstaging, subsequent requirement of more aggressive treatment for tumors, and post-pandemic overload can be prevented.
