Objective?To investigate the effectiveness of using lateral homodigital flaps pedicled with cutaneous branches of digital artery for repairing nail bed defects.?Methods?Between December 2008 and July 2010, 5 patients with nail bed defects were repaired with lateral homodigital flaps pedicled with cutaneous branches of digital artery. Nail bed defects were caused by crush injury of machine. There were 3 males and 2 females, aged from 22 to 35 years (mean, 28 years). Injured fingers included 3 thumbs, 1 index finger, and 1 middle finger. The size of the defects ranged from 1.1 cm × 1.0 cm to 1.8 cm × 1.2 cm and the size of the flaps ranged from 2.7 cm × 1.3 cm to 3.1 cm × 1.7 cm. The donor sites were covered by skin graft. The time between injury and admission ranged from 1 hour and 12 minutes to 3 hours and 24 minutes (mean, 2.1 hours).?Results?All flaps and skin grafts survived, and the incision healed by first intention. The follow-up time ranged from 6 to 9 months (mean, 7.5 months). The fingers had good appearance. Four cases gained full postoperative sensory recovery and the two-point discrimination was 4-5 mm at 3 months after operation, but it did not recover in 1 case at last follow-up. According to the functional assessment criteria of upper limb formulated by the Hand Surgery Branch of Chinese Medicine Association, the results were excellent in 4 cases and good in 1 case.?Conclusion?The lateral homodigital flaps pedicled with cutaneous branches of digital artery can repair nail bed defects without sacrifice of digital artery, and can gain a full sensory recovery. It is a feasible solution for treatment of nail bed defects especially for those unwilling to cause any damage to their toes.
The widespread implementation of lung cancer screening has led to a marked increase in the detection of early-stage disease, underscoring the clinical need for less invasive treatment strategies. Interventional pulmonology has gained increasing prominence as an alternative for patients who are unsuitable candidates for surgery, leveraging real-time imaging guidance for accurate lesion localization and offering a spectrum of local ablative modalities. In this review, we outline the current evidence regarding thermal and non-thermal ablation, photodynamic therapy, and radioactive seed implantation in the management of early-stage lung cancer. Furthermore, we examine the emerging role of advanced navigation technologies and robotic bronchoscopy platforms in interventional pulmonology. Despite encouraging outcomes, several challenges remain, including heterogeneous treatment selection criteria, the lack of standardized protocols, and limited long-term survival data. Continued technological innovation and high-quality clinical studies are essential to optimize therapeutic efficacy and expand clinical indications. Interventional pulmonology is poised to contribute substantially to personalized and minimally invasive management of early-stage lung cancer, and its integration into multidisciplinary care pathways is likely to become increasingly important in the future.
