OBJECTIVE: To summarize the effectiveness of the temporal island flap pedicled with the perforating branch of zygomatic orbital artery for repairing defects after periocular malignant tumor resection. METHODS: Between January 2015 and December 2020, 15 patients with periocular malignant tumors were treated. There were 5 males and 10 females with an average age of 62 years (range, 40-75 years). There were 12 cases of basal cell carcinoma and 3 cases of squamous carcinoma. The disease duration ranged from 5 months to 10 years (median, 2 years). The size of tumors ranged from 1.0 cm×0.8 cm to 2.5 cm×1.5 cm, without tarsal plate invasion. After extensive resection of the tumors, the left defects in size of 2.0 cm×1.5 cm to 3.5 cm×2.0 cm were repaired with the temporal island flap pedicled with the perforating branch of zygomatic orbital artery via subcutaneous tunnel. The size of the flaps ranged from 3.0 cm×1.5 cm to 5.0 cm×2.0 cm. The donor sites were separated subcutaneously and sutured directly. RESULTS: All flaps survived after operation and the wounds healed by first intention. The incisions at donor sites healed by first intention. All patients were followed up 6-24 months (median, 11 months). The flaps were not obviously bloated, the texture and color were basically the same as the surrounding normal skin, and the scars at recipient sites were not obviously. There was no complication such as ptosis, ectropion, or incomplete closure of the eyelids and recurrence of tumor during follow-up. CONCLUSION The temporal island flap pedicled with the perforating branch of zygomatic orbital artery can repair the defects after periorbital malignant tumors resection and has the advantages of reliable blood supply, flexible design, and good morphology and function.

OBJECTIVE: To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection. METHODS: Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly. RESULTS: All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location. CONCLUSION The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

Objective: To investigate the efficacies of different forms of free radial collateral artery perforator flaps in repairing the defects after oral tumor surgeries. Methods: From May 2016 to March 2021, 28 patients (22 males, 6 females, aged 35-62 years) with oral tumors admitted by Hunan Cancer Hospital received the reconstructive surgeries with the free radial collateral artery perforator flaps after removal of oral tumors, including 24 cases of tongue cancer (11 cases of tongue marginal cancer, 9 cases of tongue belly cancer and 4 cases of tongue cancer involved in the floor of the mouth) and 4 cases of buccal and oral cancer. Four forms of radial collateral artery perforator flaps were used: single perforator flaps for 6 cases, double perforators flaps for 7 cases, flaps without perforator visualization for 10 cases and chimeric perforator myocutaneous flaps for 5 cases. The recipient vessels were the superior thyroid artery and superior thyroid vein, and if second concomitant vein available, it was anastomosed with internal jugular vein in end-to-side fashion. SPSS 20.0 statistical software was used to analyze the data. Results: The mean length of flaps was (9.7±0.4) cm, mean width (4.4±0.3) cm and mean thickness (1.1±0.4) cm. The mean length of the vascular pedicles was (7.1±0.6)cm (6.0-8.0 cm), the mean diameter of the radial accessory arteries was (1.1±0.3)mm (0.8-1.3 mm). Eleven cases(39.3%) had respectively one accompanying vein and 17 cases(60.7%) had respectively two accompanying veins, with the mean diameter of (1.1±0.3) mm (0.8-1.3 mm). All the 28 flaps survived, the donor and recipient wounds healed in one stage, the appearances of the flaps were satisfactory, only linear scars remained in the donor sites, and the upper arm functions were not significantly affected. Follow up for 12-43 months showed that the flaps were soft with partially mucosalization, the reconstructed tongue and buccal cavity were in good shape, and the swallowing and language functions were satisfactory. The swallowing and language functions were retained to the greatest extent in 3 cases with near total tongue resection, although the functions were still significantly affected. There was no local recurrence of the tumor during follow-up. One case had regional lymph node metastasis, and further lymph node dissection and comprehensive treatment were performed, with satisfactory outcomes. Conclusions: The vascular pedicle of the radial collateral artery perforator flap has a constant anatomy, which can be prepared in different forms to improve the safety of the operation and minimize the donor site damage. It is an ideal choice for the repair of small and medium-sized defects after oral tumor surgery.

Objective:To investigate surgical treatment of carotid artery diseases in neck tumor surgery. Methods:A retrospective analysis of the clinical data on carotid artery treatment was conducted in the five cases of neck tumor surgeries treated at Department of Surgical Oncology, the First Peoples Hospital of Lanzhou from March 2010 to May 2020. Surgical methods, including carotid artery resection and ligation, tumor-involved artery resection and vascular reconstruction, and tumor peeling and carotid rupture repairing were used, respectively. Results:Five cases were successfully operated on. One case of carotid artery ligation was followed by intermittent dizziness and decreased contra-lateral limb strength after the surgery. The remaining patients exhibited no neurological complications. A patient with cervical low-grade myofibroblastoma developed into lung metastases 8 months after the surgery. Another patient with cervical lymph node metastases in papillary thyroid cancer developed into lung metastases 24 months after the surgery. Conclusion:Currently, surgical methods for clinical treatment of diseased carotid arteries include carotid artery resection and ligation, simple tumor peeling, tumor invasion artery resection and vascular reconstruction, and interventional therapy. Each surgical method has its own advantages and disadvantages. Therefore, the choice of treatment depends on the patient's specific conditions, physician's clinical experience, and the equipment available.

OBJECTIVE: To explore the feasibility of using indocyanine green angiography in mapping the superficial temporal vessels and assisting design and harvesting of the superficial temporal artery based forehead flap. METHODS: A clinical data of 14 patients with facial soft tissue defects repaired with superficial temporal artery based forehead flaps between October 2015 and November 2022 was retrospectively analyzed. There were 9 males and 5 females with a median age of 9.5 years (range, 3-38 years). The forehead flaps were used to reconstruct facial soft tissue defects following excision of facial scar (8 cases) or congenital melanocyte nevus (6 cases). The size of defects ranged from 3 cm×2 cm to 24 cm×9 cm. Before operation, the indocyanine green angiography was used to map the superficial temporal artery and vein, and to analyze the relationship of the arteries and veins. The forehead flaps with unilateral superficial temporal fascia as the pedicle was transferred to repair the small facial defect in 2 cases. The facial pedicle contained the frontal branch of the superficial temporal artery and 2 cm of the superficial temporal fascia around the vessel, and the tiny accompanying vein of the frontal branch of the superficial temporal artery was used as the outflow of the flap. The forehead flaps with the skin pedicle including bilateral or unilateral superficial temporal fascia and the overlying skin was pre-expanded and transferred to repair the large facial defect in 12 cases. The skin pedicle contained the frontal branch of superficial temporal artery and one of main branches of superficial temporal vein. Among the 12 cases, the frontal branch of superficial temporal vein was used as the outflow in 4 cases, and the parietal branch was used as the outflow in 8 cases. The size of the flaps ranged from 3 cm×2 cm to 30 cm×13 cm. The skin pedicles were divided at 3 weeks after the flap transfer. RESULTS: Indocyanine green angiography could clearly showed the course and branching of the superficial temporal artery and vein. Individual differences existed in the location where the frontal branch of the superficial temporal artery entered the forehead. The superficial temporal vein had great variability and did not follow the artery. One patient had expander-related complication, which resulted in 3-cm flap necrosis. The necrotic tissue was debrided and repaired with skin grafting. The other flaps totally survived and the incisions healed by first intention. All patients were followed up 2-24 months, with a median of 11.5 months. The color, texture, and thickness of the flaps matched well with those of recipient sites. Hypertrophic scar was not observed in recipient or donor site. All patients were satisfied with the reconstructive outcomes. CONCLUSION Indocyanine green angiography can clearly visualize the course and the branches of the superficial temporal arteries and veins, which can help surgeons understand the position, distribution, and concomitant relationship of the superficial temporal vessels, and make a rational surgical plan of the forehead flap.

OBJECTIVE: To investigate the feasibility and effectiveness of bilateral facial perforator artery flap in repairing large area defect in middle and lower part of nose. METHODS: The clinical data of 18 patients with large area defect in middle and lower part of nose repaired by bilateral facial perforator artery flap between January 2019 and December 2022 were retrospectively analyzed. Among them, there were 13 males and 5 females, the age ranged from 43 to 81 years, with an average of 63 years. There were 3 cases of nasal trauma, 4 cases of basal cell carcinoma, 8 cases of squamous cell carcinoma, 1 case of lymphoma, and 2 cases of large area solar keratosis. The size of the defect ranged from 3.0 cm×3.0 cm to 4.5 cm×4.0 cm; the size of unilateral flap ranged from 3.0 cm×1.3 cm to 3.5 cm×2.0 cm, and the size of bilateral flaps ranged from 3.3 cm×2.6 cm to 4.5 cm×4.0 cm. RESULTS: One patient developed skin flap necrosis after operation, and a frontal skin flap was used to repair the wound; 1 case gradually improved after removing some sutures due to venous congestion in the skin flap, and the wound healing was delayed after dressing change; the remaining 16 cases of bilateral facial perforator artery flaps survived well and all wounds healed by first intention, without any "cat ear" malformation. All 18 patients had first intention healing in the donor area, leaving linear scars without obvious scar hyperplasia, and no facial organ displacement. All patients were followed up 3-12 months, with an average of 6 months. Due to the appropriate thickness of the flap, none of the 18 patients underwent secondary flap thinning surgery. All flaps had good blood circulation, similar texture and color to surrounding tissues, symmetrical bilateral nasolabial sulcus, and high patient satisfaction. CONCLUSION The bilateral facial perforator artery flaps for repairing large area defect in middle and lower part of nose can achieve good appearance and function, and the operation is relatively simple, with high patient satisfaction.

Objective: To explore the safety and efficacy of transcatheter aortic valve replacement (TAVR) using the "All in One" single-artery/vessel technique. Methods: This is a retrospective study. A total of 30 consecutive patients underwent TAVR using the single artery/vascular technique in Beijing Anzhen Hospital from August to December 2021 were included. Baseline clinical data, operative situation, postoperative outcomes, and incidence of adverse events during hospitalization and at one month post TAVR were analyzed. Results: Mean age was (72.6±9.7) years, 16 were male patients, STS score was (4.73±3.12)%. Four patients were diagnosed as isolated aortic regurgitation (all with tricuspid aortic valves), and 26 patients were diagnosed as aortic stenosis (AS), 10 of whom with tricuspid aortic valves and 16 of whom with bicuspid aortic valves. The single-vessel technique was applied in 3 aortic stenosis cases; the single-artery technique was applied in 27 cases. Echocardiography was performed immediately after procedure and results showed no or trace perivalvular leak in 27 cases and small perivalvular leak in 3 cases; the mean aortic transvalvular gradient of 26 AS patients decreased from (50.4±16.0) mmHg (1 mmHg=0.133 kPa) to (9.4±3.2) mmHg (P<0.001). The procedure time was (64.8±18.9) min. There were no intraoperative death, valve displacement, conversion to surgery, coronary artery occlusion in all 30 patients. There were no major cardiac adverse events such as myocardial infarction or stroke occurred during hospitalization or at follow-up. One-month follow-up echocardiography indicated prosthesis works well. The symptoms were significantly alleviated, and the Kansas City Cardiomyopathy Score (KCCQ score) of all patients increased from 48.1±18.4 to 73.5±17.6 (P<0.001). Conclusions: TAVR using the single artery/vessel technique is safe and feasible. This technique is related to reduced access complications and worthy of wide application.

Objective: To examine the safety and feasibility of three-dimensional (3D) surgical planning system for guiding robot-assisted selective artery clamping partial nephrectomy (RASPN) in completely endophytic renal tumor. Methods: Clinical data of 32 patients who suffered from completely endophytic renal tumor and underwent RASPN associated with 3D surgical planning system in Department of Urology, Sun Yat-Sen University Cancer Center from November 2018 to August 2021 were analyzed retrospectively. There were 21 males and 11 females, with the age (M (IQR)] of 45.0 (17.5) years (range: 30 to 68 years). Fifteen tumors were located on the left and 17 on the right. Maximum tumor diameter, R.E.N.A.L. Score and preoperative estimated glomerular filtration rate (eGFR) were 27.5 (13.0) mm (range: 14 to 50 mm), 10.0 (1.8) (range: 7 to 11), and 105.5 (15.7) ml·min^-1·(1.73 m²)^-1 (range: 71.1 to 124.8 ml·min^-1·(1.73 m²)^-1), respectively. The 3D reconstruction before RASPN was performed in all patients to formulate surgical planning, mainly including stereo localization of renal mass, confirmation of tumor feeding artery, and injury prediction of collecting system or vessel via "2 mm distance method" defined as probable damage of renal pelvis/calyx and artery/vein when these tissues were less than 2 mm away from tumor. Results: Totally 32 patients successfully underwent RASPN guided by 3D surgical planning system, without conversion to open operation or radical nephrectomy. Rapid location of tumor and selective clamping of artery were achieved in all cases and no one encountered global ischemia, with branch occlusion time of 24.5 (15.4) min (range: 12 to 60 min) and coincidence rate of 95.0% (57/60) between planned and actual clamping vessels. The sensitivity and specificity of 2 mm distance method for predicting the injury of collecting system were 13/15 and 17/17, respectively. The operating time of 185 (48) minuetes (range: 76 to 295 minutes) and estimated blood loss of 200 (350) ml (range: 20 to 800 ml) were observed, without intraoperative transfusion case. There was one patient performed with renal vein repair. Clavien-Dindo postoperative grade Ⅱ and Ⅲa bleeding complications occurred in 2 cases, and no postoperative urinary fistula was found. The length of hospitalization was 3 (0) days (range: 2 to 10 days). The pathological diagnosis demonstrated 4 chromophobe cell carcinomas and 2 angiomyolipomas, besides 26 clear cell carcinomas including one positive surgical margin. The postoperative latest eGFR was 103.9(18.5) ml·min^-1·(1.73 m²)^-1 (range: 75.8 to 122.3 ml·min^-1·(1.73 m²)^-1) and no tumor recurrence or metastasis was detected during the follow-up time of 15.4 (13.9) months (range: 3 to 35 months). Conclusion: For RASPN in completely endophytic renal tumor, 3D surgical planning system is contributed to determining mass position, defining tumor feeding artery, and predicting collecting system/vessel injury, which benefited precise tumor resection, postoperative renal function preservation, and perioperative urinary fistula and bleeding complication decrease.
