Background: Breast reconstruction with implants is now the preferred procedure following mastectomies. For successful reconstruction, accurate evaluation of the patient and skin flap viability is essential. This study aimed to analyze the impact of risk factors on mastectomy skin flap necrosis (MSFN) and the effectiveness of indocyanine green angiography (ICGA) in preventing complications. Methods: Fifty consecutive patients undergoing mastectomy were divided into two groups (arms A and B) based on the method of skin flap evaluation (ICGA vs. clinical assessment, respectively). Demographic details and the risk factor incidence were collected, and complication rates were compared between the two groups. Univariate analysis was conducted to identify correlations between mastectomy skin flap necrosis and the aforementioned risk factors. Results: The two groups showed comparable demographics and incidences of risk factors. Patients in arm A exhibited a lower rate of complications and reinterventions, although no significant differences were observed. Statistical analysis revealed a significant association between BMI, implant volume, and MSFN. Conclusions: ICGA proves to be an effective diagnostic tool for assessing skin flap viability. When coupled with meticulous patient selection, it aids in preventing complications.

Temporal migraines (TM) present with throbbing, pulsating headaches in the temporal area. Different surgical techniques ranging from resecting the auriculotemporal nerve (ATN) and or ligating the superficial temporal artery (STA) have shown similar good results to decrease TM symptoms. No conclusive data supports a specific disease of the STA in TM patients. A minimally invasive technique is proposed to preserve both vascular and nerve structures. Patients with drug resistant TM were selected and treated with two techniques: nerve sparing and nerve and artery sparing. The study included 57 patients with TM, with an average age of 47.5 years. TM improvement was quantified after at least one year of follow up time. STA biopsies were sent for histological analysis. Forty-two patients underwent nerve-sparing decompression, with a therapeutic success rate of 78.6%, corresponding to 22.1 days with migraine per month decreasing to 6.2. Histological analysis of the STA showed varying degrees of endofibrosis in 75% of the samples. Histological results do not correlate with the intensity of symptoms before or after surgery. Fifteen patients underwent nerve and artery sparing arteriolysis, with an overall therapeutic success rate of 86.6% of which 80% had >90% improvement. The average migraine days dropped from 24 to 2.5 days per month in this group. Minimally invasive nerve sparing approaches are an effective and safe treatment to improve drug resistant TM symptoms. Endofibrosis of the STA was present in 75% of the cases, but it was found to be unrelated to pre-operative symptoms and outcome. Results are promising, but the limited numbers of patients treated with artery and nerve sparing technique needs further investigations.

Addressing post traumatic lower limb neuropathic pain is challenging across medical specialties. To address this potentially devastating condition, several invasive and non-invasive approaches have been proposed with inconsistent results. Adipose fat transfer (AFT), also known as fat grafting, is a regenerative medicine technique in which a patient's own fat is harvested from one area of the body (usually through liposuction) and then injected into another area for various purposes, such as aesthetic contour enhancement or reconstruction and regeneration of scarred tissues. We analyze the effects of fat grafting for neuropathic pain combined with neuroma excision (hybrid technique, hAFT) or alone (AFT). A retrospective review was conducted on 22 patients with neuropathic lower limb pain, after trauma or orthopedic surgery treated with hAFT (n = 9) or AFT (n = 13). Reduction in VAS scale more than 50 % was observed in 6 patients (66 %) treated with hybrid technique and in eleven patients (85 %) treated with AFT alone. Among these, complete pain reduction (>91 %) was achieved in 33.3 % of hAFT and 54 % of AFT technique. A 3.2 points reduction in VAS was found in the hAFT group versus 5.8 points in the AFT group (p = 0.035). This pioneering use of AFT emerges as a minimally invasive breakthrough, promising significant improvement in reconstructing scarred subcutaneous tissue and managing neuropathic pain.

Addressing post-traumatic lower limb neuropathic pain is challenging. Several invasive and non-invasive approaches have been described with mixed results including wide neurolysis, neurectomy, and neuroma resection. Recently, minimally invasive techniques as adipose fat transfer showed good effectiveness and low complication rate. Adipose fat transfer is surgical technique in which the patient’s own fat is harvested and injected to regenerate another area. The aim of this chapter is to examine the different techniques used to treat neuropathic pain after trauma and scar entrapment, focusing on our experience on minimally invasive techniques such as adipose fat transfer for scar regeneration and pain relief.
