Breast cancer incidence increases annually due to the aid of established screening programs, leading to the discovery of breast cancer in its early stages. Surgical treatment is an integral part of early breast cancer management to achieve local control. Axillary surgical interventions such sentinel lymph node biopsy (SLNB) and axillary lymph node clearance (ALND) aim to stage the axilla as an adjunct to the management of the primary breast tumor. In this paper, we reviewed female breast cancer patients aged 30 - 60 who underwent surgical treatment of SLNB and/or ALND with reporting the prevalence of lymphedema and other associated complications and risk factors. Methodology: A cross-sectional non-interventional study, with a sample size of 250 including breast cancer cases from 2016 to 2019 at National Guard Hospital (NGH) in Jeddah, Saudi Arabia. Results: A total of 253 breast cancer cases were included in this study, with a mean age of 53 years, 52.7% were postmenopausal and positive family history was present among 21% of cases. Further, 90.9% of the cases had unilateral disease. Staging was as follows: stage I 14.5%, stage II 45.2%, stage III 37.1%, and stage IV 3.2%. Mastectomy was done in 73.4% cases and lumpectomy was performed in 34.1% of cases. In addition, 93.3% of patients had SLNB and 49% of them were positive. Axillary dissection was performed in 69.6% of our patients. Radiotherapy and chemotherapy were given to 71.8% and 80.4% of cases respectively. Among the chemotherapy (chemo) recipients, 40.2% received adjuvant chemo, 54.5% received neoadjuvant chemo, and the remaining 5.3% received both. Further, the most prevalent complication was pain accounting for 42.1% of total complications, and the least prevalent was cellulitis 4%. Also, seroma developed in 18.3% cases, paresthesia noted in 5.6% of cases, winged scapula was reported as 2%, weakness and necrosis were seen in 6% and 13.1% of cases respectively. Axillary vein thrombosis and lymphangiosarcoma were reported in none of the patients (0%). Lymphoedema accounted for 16.1% of overall complications, 85% of the patients who developed lymphedema had undergone ALND, and 12.9% and 14.4% received radiotherapy and chemotherapy respectively. Lymphedema was observed in breast cancer stages as follows: stage I 1.2%, stage II 7.2%, and stage III 5.2%. Patients with body mass index (BMI) of 30 - 39 kg/m<sup>2</sup> had 7.2% prevalence of lymphedema compared to other BMI groups. Overall mortality was 8.3%. Conclusion: The findings of our study suggest that the prevalence of lymphedema was higher in ALND patients with locally advanced tumors, and higher BMI, compared to patients with stage I breast cancer and low BMI. Further, the prevalence of lymphedema in patients who underwent ALND was significantly lower than those who were treated by lumpectomy 10.3% (p-value = 0.034) in comparison to mastectomy 19.3%.展开更多

Subject and Method: Clinical case report and literature review. Study of a patient had an indication for permanent pacemaker implantation who had complication of subclavian artery bleeding during the procedure. Result: An 84-year-old female patient was admitted to the hospital because of fainting spells with chest pain, on the background of dangerous complex arrhythmias and ischemic heart disease, and was prescribed a pacemaker for this patient. The patient had complication occurred during the procedure, which left subclavian artery bleeding was detected and treated promptly, a cardiac pacemaker was implanted on the right side of the chest, and the patient had a successful endovascular stent cover in the left subclavian artery. Conclude: Subclavian artery bleeding is a rare complication in the procedure of permanent pacemaker implantation, but it can still occur and requires quick detection and timely treatment, needs to be successful in cardiac pacemaker placement and subclavian artery drug-eluting stent cover placement intervention. Individualized patient risk assessment is needed;appropriate and standardized intervention techniques and experience can reduce the occurrence of this variable.展开更多

Materials and Methods: A descriptive retrospective study was based on the medical records of patients who suffered vascular axillary and/or brachial plexus trauma and who underwent surgical repair at the Abidjan Cardiology Institute from January 2008 to June 2022. Epidemiological, anatomo-clinical and surgical data were studied. Results: Thirty-four medical files belonging to 33 men and one woman, aged 32 on average, were collected. The circumstances of occurrence were dominated by the stab wound (n = 22). The combinations of injuries were as follows: associated involvement of the axillary artery and vein (n = 4);isolated involvement of axillary artery (n = 3);isolated involvement of the axillary vein (n = 2);associated involvement of the axillary artery and brachial plexus (n = 17);associated involvement of the axillary artery and vein and brachial plexus (n = 08). Anatomic lesions included acute arterial lesions (n = 29) and arteriovenous fistula (n = 1) and false aneurysms (n = 4). All patients were operated on under general anesthesia;vascular repair included direct suturing (n = 16), arterial and venous bypass using a long saphenous graft (n = 9), prosthetic arterial bypass (n = 5) and prosthetic flattening-graft (n = 4). Brachial plexus surgery consisted of an end-to-end anastomosis of each transected bundle in all cases (n = 25). The medium-term postoperative course was marked by success without functional sequelae in 88.24% of cases (n = 30) and by the persistence of distal paralysis of the thoracic limb after 6 months in 05.88% (n = 2) of all patients, i.e., 8% of patients who presented with brachial plexus injury. Conclusion: The concomitant surgical treatment of these axillary vascular and nerve lesions has given good results. However, if paralysis of the thoracic limb persists after 6 to 12 months, the patient should be referred to a specialist in brachial plexus surgery.展开更多
