It has the advantages of hidden donor site, the same operative field, great comparability of flap and finger skin, and it can be used as a vascularized tendon or nerve graft.
Objective To study the anatomical basis of micro transverse flap pedicled with the superfical palmar branch of radial artery from the palmar wrist for using this free flap to repair soft tissue defect of the finger. Methods Thirty-eight fresh upper limb specimens (22 males and 16 females; aged 26-72 years with an average of 36 years; at left and right sides in 19 limbs respectively) were dissected and observed under operating microscope. Two specimens were made into casting mould of artery with bones, and 2 specimens were injected with red emulsion in radial artery. Thirty-four specimens were injected with 1% gentian violet solution in the superfical palmar branch of the radial artery. A transverse oval flap in the palmar wrist was designed, the axis of the flap was the distal palmar crease. The origin, distribution, and anastomosis of the superfical palmar branch of the radial artery were observed. Results The superficial palmar branch of the radial artery was constantly existed, it usually arises from the main trunk of the radial artery, 1.09-3.60 cm to proximal styloid process of radius. There were about 2-5 branches between the origin and the tubercle of scaphoid bone. The origin diameter was 1.00-3.00 mm, and the distal diameter at the styloid process of radius was 1.00-2.90 mm. The venous return of flap passed through 2 routes, and the innervations of the flap mainly from the palmar cutaneous branch of the median nerve. The area of the flap was 4 cm × 2 cm-6 cm × 2 cm. Conclusion The origin and courses of the superficial palmar branch of the radial artery is constant, and its diameter is similar to that of the digital artery. A transverse oval flap pedicled with the superfical palmar branch of radial artery in the palmar wrist can be designed to repair defects of the finger.

Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
Objective To investigate the safety and feasibility of transcatheter arterial chemoembolization (TACE) assisted by transradial approach and cone beam computed tomography (CBCT) three-dimensional vascular reconstruction in the treatment of primary liver cancer. Methods The clinical data of 124 patients with primary liver cancer who underwent precision TACE via radial artery in our hospital from May 2018 to December 2019 were retrospectively collected. Results Among the 124 patients, 118 patients were successfully punctured through the left radial artery and completed the TACE operation. The operation time was (109.57±31.32) min, and the median of postoperative hospitalization was 3 d. One patient changed to the right radial artery to complete TACE due to chronic renal failure and left brachial artery and vein puncture and catheterization before operation. The operation time was 119 minutes, and the patient was discharged after 5 days of hospitalization. After successful puncture of the left radial artery in one patient, the forearm artery was twisted into a loop and the guide wire catheter failed to pass, and the right femoral artery was used to complete TACE. The operation time was 123 minutes, and the patient was discharged after 4 days of improvement. The radial artery puncture was unsuccessful in four patients, and the right femoral artery approach was used to complete the operation; the operation time was (111.66±32.77) min, and the median of postoperative hospitalization was 3 d. One of the patients successfully completed up to 5 consecutive TACE via the radial artery. All patients underwent precision TACE with superselective cannulation assisted by CBCT three-dimensional vascular reconstruction. No vascular injury andocclusion, urinary retention, subcutaneous hemorrhage, and other complications occurred in all patients. Conclusions Trans-radial arterial precision TACE is safe and effective, which can be repeated many times and has few complications and high patient comfort. It can be used as one of the routine approaches of TACE.
ObjectiveTo summarize the application experience of off-pump total arterial coronary artery bypass grafting with left internal thoracic artery and bilateral radial arteries, and evaluate its safety and efficacy. MethodsThe clinical data of the patients with severe multiple coronary arteries stenosis undergoing off-pump total arterial coronary artery bypass grafting with left internal thoracic artery and bilateral radial arteries in the Affiliated Hospital of University of Electronic Science and Technology ＆ Sichuan Provincial People’s Hospital from November 2020 to April 2023 were retrospectively analyzed. Results Finally 24 patients were enrolled. There were 23 males and 1 female. The mean age was 53.63±4.33 years. The cardiac function class was from grade Ⅱ to Ⅲ according to New York Heart Association. There were 3.17±0.38 distal anastomoses. Y graft in 12 patients and sequential graft in 4 patients were performed. Coronary endarterectomy in 1 patient, intraaortic balloon pump (IABP) catheter implantation in 10 patients, and thymoma resection in 1 patient were also performed simultaneously. The operation time was 308.13±30.39 mi. The ventilator support time was 15.42±7.42 h, and the intensive care unit stay time was 46.08±27.32 h. The postoperative hospital stay time was 11.71±1.90 d. There were no death, but acute renal failure in 1 patient and cerebral infarction in 1 patient were found after operation. The postoperative left ventricular end diastolic diameter by echocardiogram before discharge was significantly reduced, the postoperative left ventricular ejection fraction and short axis shortening rate were significantly increased, compared to preoperative ones (P≤0.05). All arterial grafts were patent suggested through coronary artery computed tomography angiography (CTA) examination before discharge. All patients were followed up for 14.58±8.75 months. No angina recurrence and death were found. All arterial grafts were still patent in 16 patients suggested through coronary artery CTA or angiography examination at 1 year after operation. Conclusion Off-pump total artery coronary artery bypass grafting with left internal thoracic artery and bilateral radial arteries for patient with severe multiple coronary arteries stenosis is safe and effective. For high-risk patient, IABP assistance during operation is recommended.
