Objective: To study the clinical application of the neurovascular island flap of the calf supported by perforating branches of peroneal artery for the soft tissue defects of ankle and the foot.
Methods: The flaps were used in 27 cases to repair the soft tissue defects of ankle and the lower leg from February 2004 to December 2007. Among them, 21 cases were male and 6 cases were female, ranging in age from 7 months to 64 years, with an average of 31.5 years. There were 7 cases with external malleolus, 5 cases with medial malleolus, 8 cases with dorsum of foot, 7 cases with achilles tendon. The range of soft tissue defects was from 2.5 cm x 3.5 cm to 10 cm x 24 cm and the range of flap was from 3 cm x 4 cm to 12 cm x 26.5 cm.
Results: Seven cases were lightly swelling and distension after operation from 3 to 7 days. After 7 days, the swelling subsidised gradually and all flaps survived. In the follow-up for 3-12 months with an average of 5 months, all flaps showed fine appearance without fat and clumsy. The function of donor site was very well.
Conclusion: The neurovascular island flap of the calf supported by perforating branches of peroneal artery can provide reliable blood supply, long reversed distance and wide repairing limitation and the proximal end of flap can reach to popliteal fossa. It is a good method to repair the defects of the lower leg and the foot.

First pass effect in patients with large core infarcts undergoing mechanical thrombectomy: subgroup analysis of the prospective international ASSIST registry.
J Neurointerv Surg
January 2025
Semmes-Murphey Neurologic and Spine Institute, Memphis, Tennessee, USA.
Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.
Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.
Comparative analysis of disruptive events in robotic and laparoscopic radical prostatectomy.
J Robot Surg
January 2025
Sengupta Urology, Glen Waverley, Vic, Australia.
Article Synopsis
- The study compares laparoscopic and robotic-assisted radical prostatectomy to identify types of disruptive events during surgery, using rigorous video analysis and consultations with surgeons.
- The analysis of 54 surgeries revealed that robotic-assisted procedures had significantly fewer disruptions, with around 41% fewer external and 33% fewer internal disruptions compared to laparoscopic methods.
- Key findings include that RARP resulted in fewer major disruptions due to better visibility and improved surgical coordination, highlighting the advantages of robotic assistance in complex surgeries like radical prostatectomy.

Background: Secondary stroke prevention in patients with atrial fibrillation (AF) is one of the fastest growing areas in the field of cerebrovascular diseases. This Scientific statement from the World Stroke Organization Brain & Heart Task Force provides a critical analysis of the strength of current evidence this topic, highlights areas of current controversy, identifies knowledge gaps, and proposes priorities for future research.
Methods: We select topics with the highest clinical relevance and perform a systematic search to answer specific practical questions.
How Reliable Is the Posterior Belly of the Digastric Muscle in Preventing Carotid Injury During Neck Dissection?

Otolaryngology, Head and Neck Surgery, Texas Tech University Health Sciences Center School of Medicine, Lubbock, USA.
The posterior belly of the digastric muscle, referred to as the "resident's friend," serves as a valuable anatomical landmark because identification of its location during head and neck surgery helps to secure vital structures. A 53-year-old female was referred for an oral cavity mass with a biopsy confirmed squamous cell cancer. A physical exam revealed a 4 cm long and 2 cm wide right ulcerated oral tongue mass.

Background And Objectives: Post-ischemic stroke (IS) outcomes vary widely among individuals, independently of clinical factors. This variability could be related to epigenetic mechanisms that regulate biological processes involved in recovery after ischemia. While several microRNAs (miRNAs) and their target genes are implicated in the pathophysiology of IS, their role in functional outcomes remains unclear.
