Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...

BACKGROUND: Recurrence rate after curative surgical resection of Hepatocellular carcinoma (HCC) remains high. Postoperative hepatic arterial infusion chemotherapy (HAIC) has been suggested to improve survival. This study is to investigate the efficacy of HAIC in the patients with poor tumor factors such as vascular invasion or multiplicity. METHODS: From 2006 to 2014, 221 patients with HCC undergoing hepatectomy and pathologically staged as ≧ T2 (American Joint Committee on Cancer TNM staging system, 7th edition) were included...

INTRODUCTION: Many structural and functional damages are observed in cells and tissues after reperfusion of previously viable ischemic tissues. Acute ischemia reperfusion (I/R) injury of lower extremities occurs especially when a temporary cross-clamp is applied to the abdominal aorta during aortic surgery. Research regarding the treatment of I/R injury has been increasing day-by-day. In this study, we aimed to investigate the effect of picroside II on skeletal muscle of rats experiencing simulated I/R...

BACKGROUND: Large soft tissue defects of ankle and foot always have been challenging to reconstruct. Reverse sural flaps, free flaps have been used for this problem with variable success. Reverse peroneal artery flap is an option to use with reliability without microvascular repair. Connections of peroneal artery around talus and ankle joint are deep and reliable with anterior tibial and posterior tibial artery. Arterial inflow and venous drainage improved with including short saphenous vein and reverse sural artery in the flap...

BACKGROUND AND OBJECTIVE: The clinical application of laser-assisted vascular anastomosis is afflicted by unreliable and low bonding strengths as well as tedious handling during microvascular surgery. The challenge to be met arises from the flow-off of the chromophore during soldering that changes the absorption and stains the surrounding tissue, leading to an uncontrollable thermal damage zone. In this study, we investigated the feasibility to produce an indocyanine green (ICG)-loaded patch by electrospinning and tested its applicability to both in vitro and in vivo microvascular laser soldering...

Microvascular decompression (MVD) is a novel surgical procedure predominantly performed for treating trigeminal neuralgia (TN) and hemifacial spasm (HS). Multiple studies have proven the long-term success of MVD for both these conditions. The most common complications of MVD reported include chemical meningitis, facial hypesthesia, cerebrospinal fluid leak, facial paresis, and hearing loss. Delayed facial palsy (DFP) is an uncommon complication mostly noted in MVD for HS and after the removal of acoustic tumors...

The nose is a critically important aesthetic and functional portion of the face. We can explore nasal defects following trauma or tumor resections. Reconstructive techniques based on primary closure, skin graft, local flap, regional flap and microvascular free tissue transfer provides an algorithmic framework applicable to any reconstructive problem. From 2010 to 2016, 33 patients were treated with nasal reconstruction. Malignant tumor resection was the main cause of nasal defect. The most common tumor resected was BCC (basal cell carcinoma) followed by SCC (squamous cell carcinoma)...

Diabetic retinopathy (DR) is a microvascular complication of diabetes mellitus and a major preventable cause of blindness. Strict control of blood glucose, blood pressure, and lipid profiles are the pivotal criteria to reduce the risk of developing DR. Although timely intervention with laser photocoagulation therapy could mitigate the progression of DR, it may not significantly improve visual acuity. Therefore, invasive surgical interventions such as vitrectomy are sometimes the only option to treat or manage advanced stages of DR...

PURPOSE: Hormone (anti-estrogen) therapy (HT) plays a major role in hormone receptor-positive breast cancer management. The latest guidelines propose to extend the duration of adjuvant treatment from 5 to 10 years. The association between HT and thromboembolic or microvascular complications during breast reconstruction has been investigated. However, while estrogens play a crucial role in wound healing, no study has assessed the impact of tamoxifen or aromatase inhibitors on other postoperative complications, including wound healing complications...

Unplanned hospital readmission following head and neck cancer surgery is common and associated with significant negative consequences. Because of the vital role that microvascular free tissue transfer plays in the management of head and neck oncologic defects, its relationship to unplanned hospital readmission requires attention. In this review, the incidence of, risk factors for, and reasons for unplanned readmission in patients undergoing free flap reconstruction for head and neck cancer are analyzed. The role of free flap reconstruction as a separate risk factor for unplanned readmission in patients with head and neck cancer is described...

Lauren E Rotman, Mark R Harrigan
Dr. Norman Chater, a University of California, San Francisco-trained microvascular neurosurgeon, dedicated his career to the development of surgical bypass techniques. His work contributed to advancements in microvascular anatomy and the development of cerebral revascularization techniques. He identified Chater's point, an extracranial landmark that marks the posterior extent of the Sylvian fissure, which upon craniectomy reliably exposes vessels of the angular gyrus, vasculature found to be most appropriate for bypass procedures due to their accessibility and vascular diameter...

BACKGROUND: It is crucial to find a balance between functional and oncological outcome when choosing an adequate method for the management of vocal fold leukoplakia. Therefore, a detailed examination is a milestone in the decision-making process. AIM: To examine whether narrow-band imaging (NBI) can be helpful in vocal fold assessment in the case of leukoplakia and how to overcome the "umbrella effect"- understood as the submucosal vascular pattern hidden under the plaque...

Objective: To investigate the effect of irradiation to anastomosis from preoperative radiotherapy for patients with rectal cancer by studying the pathological changes. Methods: In this retrospective study, patients enrolled in the FOWARC study from January 2011 to July 2014 in the Sixth Affiliated Hospital of Sun Yat-Sen University were included. In the FOWARC study, enrolled patients with local advanced rectal cancer were randomly assigned to receive either neoadjuvant chemo-radiotherapy or chemotherapy. Among these patients, 23 patients were selected as radiation proctitis (RP)group, who fulfilled these conditions: (1) received neoadjuvant chemo-radiotherapy followed by sphincter-preserving surgery; (2) developed radiation proctitis as confirmed by preoperative imaging diagnosis; (3) had intact clinical samples of surgical margins...

INTRODUCTION: Insufficient microvascular oxygenation (μHBO2) of the intestinal mucosa worsens outcome of septic patients. Hypercapnia ameliorates μHBO2, mediated via endogenous vasopressin release. Under physiological conditions, blockade of the endogenous sympathetic nervous system abolishes this protective effect of hypercapnia. The aim of our study was therefore to evaluate the role of the endogenous sympathetic nervous system during hypercapnia on intestinal μHBO2 under septic conditions...

This review aims to provide a summary of the flowmeter devices used in microvascular surgery and assesses their contribution to improving the clinical outcomes of free tissue transfer. Flowmeters are widely accepted as the standard method of intraoperative assessment of the patency of coronary vascular anastomoses, providing thresholds that predict outcome. There is limited evidence regarding the use of flow measurements in plastic surgery microvascular anastomoses; however, flowmetry appears to have some role in postoperative free flap monitoring and prevention of complications...

BACKGROUND AND OBJECTIVE: Animal models using rodents are frequently used for the purpose of practicing microvascular anastomosis - an essential technique in cerebrovascular surgery. However, safely and efficiently exposing rat's target vessels is technically difficult. Such difficulty may lead to excessive hemorrhage and shorten animal survival. This limits the ability to perform multiple anastomoses on a single animal and may increase the overall training time and costs. We report our model for microsurgical bypass training in rodents in two consecutive articles...

BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...
