Direct-to-implant reconstruction is one of the breast repair techniques after mastectomy. Implant selection is critical in the short- and long-term success of direct-to-implant reconstruction after nipple-sparing mastectomy. In this study we developed a 10-step algorithm that we use before and during surgery. We aimed to obtain natural and stable breast reconstruction with this algorithm. In addition, we also aimed to evaluate which implants were selected using this algorithm and their short- and long-term outcomes. This retrospective study included 218 patients aged 27 to 60 years who underwent mastectomy and direct-to-implant reconstruction between November 2018 and December 2021. The patients were assigned into 4 groups according to amount of breast tissue removed. We developed a 10-step algorithm and these included: breast base, amount of breast tissue removed, evaluation of mastectomy skin flap, breast projection, ptosis, unilateral/bilateral reconstruction, chest wall deformity, patient’s request, comorbid conditions and stabilization and arrangement of novel sulcus. The evaluation was made when the patient’s photographs were taken at least 1 year after the surgery. The highest number of patients was recorded in group 3; in addition, mean age was also highest in group 3. The lowest number of patients was recorded in group 4. The body mass index showed a progressive increase from group 1 to group 4. Medium height moderate profile prosthesis was used in 81.7% while medium height moderate plus profile prosthesis was used in 18.3% of breasts included. We used larger prosthesis up to 58.1% when compared to the tissue removed in group 1 while we used smaller prosthesis by 25.6% in group 4. In the anterior view, the medial and lateral arch of the lower pole of the breast was obtained in all patients. Obvious asymmetry developed in 4 patients. In lateral and oblique views, upper and lower pole natural breast images were obtained in all patients, except for 5 patients. There was no sulcus inferior displacement in any patient. Implant extrusion did not occur in any patient. This algorithm is an easy to use and effective method to obtain a stable and natural breast image in the long-term.

Loss of breast, which is an important body marking of women, causes a huge decrease in quality of life (QoL) after treatment. In order to overcome this morbidity and increase QoL, nipple sparing mastectomy (NSM) has been developed. Even though the demand for better cosmetic results has yielded endoscopic nipple sparing mastectomy, limitations like unsuitable optical window and limited manual control of rigid-tip instruments, and struggling to keep dissection space have led robotic nipple sparing mastectomy (rNSM) to be developed. Records of three patients who underwent to rNSM for invasive breast carcinoma with DaVinci Xi (Intuitive Surgical, Sunnyvale, CA) in affiliated hospitals of xxxxx xxxxx xxx xxxx University, Research Institute of xxxxx in 2018 were investigated retrospectively. In all breasts (n=4), dissection was started from the posterior side of breast. In the unit, 738 breast cancer patients underwent surgery between 2018 and 2019 with an NSM ratio of 31.4% (n=232). Of these patients, three underwent rNSM with DaVinci Xi robotic system. The operation was performed on the left breast in one patient, right in one, and bilateral in one patient. Only in patient #2, who was a neoadjuvant chemotherapy recipient, seroma was observed six weeks after surgery (3 weeks after removal of drains) and spontaneously resolved in 4 weeks. No other complication was seen in all patients. In the follow-up period of median 21 months, no loco-regional recurrence or distant metastasis was seen. A single incision robotic mastectomy can be performed easily and safely when the dissection starts from the pre-pectoral plane rather than the subcutaneous plane.

Detachment and embolization (DE) is a rare complication of totally implantable central venous access devices (TIVADs). This study aimed to analyze clinical findings, etiology, and treatment options in DE of TIVADs. Patients who experienced DE between 2010–2019 were included. Indications, implantation techniques, time to diagnosis, patient complaints, diagnostic methods, rupture site, location of embolization, treatment methods, and chest X-rays prior to detachment were analyzed retrospectively. DE of TIVAD was detected in 12(1.2%) patients. Eleven patients had breast cancer and one had colon cancer. Mean age at implantation was 45.3 ± 9.6(31–61.3) years. Seven (58%) patients were asymptomatic, four (33.3%) had TIVAD malfunction, and one (8.3%) had pain and swelling at port site after injection. Mean time from implantation to diagnosis was 1149.92(16–2795) days. The etiologies comprised Pinch-off Syndrome (POS) in eight (66%) patients, detachment directly adjacent to the lock mechanism in three (25%) patients, and probable iatrogenic injury during explantation in one (9%) patient. The most common site of embolism was the superior vena cava (25%). While the embolized fragment was removed percutaneously in 11 patients, medical follow-up was treatment choice for one patient. DE is a rare complication with an incidence rate of 1.2% in this study. Since most patients were asymptomatic, chest radiography plays an important role in diagnosis. The most common cause was POS, and it can be prevented by inserting the catheter from lateral third of the clavicle during subclavian vein catheterization. The first-choice treatment was percutaneous femoral retrieval. However, if not technically possible, alternative treatment options are thoracotomy or follow-up with anticoagulant therapy.
