A Prospective Double-Blind Randomized Controlled Trial of Radiofrequency versus Laser Treatment of the Great Saphenous Vein in Patients with Varicose Veins
Published in Juan Carlos Jimenez, Samuel Eric Wilson, 50 Landmark Papers Every Vascular and Endovascular Surgeon Should Know, 2020
Juan Carlos Jimenez, Samuel Eric Wilson
The GSV was cannulated percutaneously at the level of the knee using a Seldinger technique and duplex ultrasound guidance. Standard tumescent anesthesia was used. In both groups, phlebectomy hooks were used for simultaneous avulsion of infragenicular varicosities that had been marked before surgery.
Pre-, intra-, and post-treatment use of duplex ultrasound (thermal and non-thermal)
Published in Joseph A. Zygmunt, Venous Ultrasound, 2020
The addition of duplex ultrasound to guide therapeutic intervention adds to the accuracy and also the safety of the procedures undertaken. This application is being used in many fields of medicine for biopsy, nerve blocks, regional anesthesia, and insertion of catheters and central lines, to name a few. In the following text, discussion points will focus upon concepts related primarily to thermal ablation procedures, specifically: (i) preoperative marking; (ii) access for intervention; (iii) placement and advancement (or positioning) of the catheter; (iv) administration of tumescent anesthesia; (v) monitoring treatment; and (vi) immediate post-treatment imaging. Of note, the current (second) edition of this book now includes content related to the newer non-thermal non-tumescent (NTNT) and non-thermal non-tumescent non-sclerosant (NTNTNS) techniques.
Tumescent Anesthesia

Tumescent anesthesia (TA) is a distinct form of local anesthesia that employs a large volume of fluid (usually normal saline) containing a very dilute concentration of anesthetic (primarily lidocaine) and vasoconstrictor (epinephrine), as well as other additives (notably, sodium bicarbonate). Local anesthesia is defined as the loss of sensation within a confined area without alteration of the patient’s consciousness. Tumescent is derived from the Latin word tumescere, meaning to swell. It is the swelling and resultant firmness of the tissue that both contributes to the regional anesthetic effect and also facilitates the procedure for which it is now most commonly employed, liposuction. TA is local infiltration anesthesia and should not be confused with regional anesthesia as occurs with peripheral nerve blockade.
Integrating the Fast-Track surgery concept into the surgical treatment of gynecomastia

Choice of anesthetic technique for operation plays an important role in a successful fast-track rehabilitation program. Traditionally, the surgical treatment of gynecomastia is performed under general anesthesia and the recovery would thus be attenuated. By contrast, the local tumescent anesthesia that caused minimal stress response was our primary choice in the fast-track program. There were no special requirements about preoperative fasting and postoperative oral intake, which may help reducing relevant adverse effects and patients’ discomfort. In addition, the total costs were reduced as the general anesthesia fee was saved. However, if there are individual patients who do not accept the fast-track protocol or are scared of surgery in awake state, the general anesthesia still remains a good alternative.
Upper airway obstruction following radiofrequency-assisted liposuction of the neck and lower face: a case report

Radiofrequency-assisted liposuction (RFAL) recently gained popularity for non-excisional skin tightening, thereby broadening the plastic surgeons’ armamentarium for specific patients whose skin laxity is not ‘severe’ enough for surgical excision and not ‘mild’ enough for traditional non-invasive esthetic modalities. It is also an option for recurrent skin laxity despite prior surgical excision, and for improving skin laxity in patients who want to avoid surgery and are willing to accept more modest results [1]. RFAL involves the delivery of a controlled amount of energy that is converted to heat, resulting in fat liquefaction, hemostasis and skin contraction by tightening the fibroseptal network, while promoting new collagen and elastin formation and diminishing adipocytes [2]. It is regarded as safe and effective with general anesthesia [3] and local tumescent anesthesia in the awake patient [1]. We report the case of upper airway obstruction following a subcutaneous hematoma with diffuse soft tissue hardening and fat necrosis of the neck and lower face following RFAL.
Autologous fat transplantation for the treatment of abdominal wall scar adhesions after cesarean section

Approval for autologous fat harvesting and transplantation was obtained from the Institutional Review Board of Medical Science, Jinan University, and written consent was obtained from the study participants. The liposuction sites were located in the lower abdomen, thigh, and knee. The incision for lower abdominal liposuction was made at the inner edge of the umbilicus. Lidocaine (0.125%) was used as a topical infiltrating anesthetic. A no. 11 scalpel was used to make an incision of approximately 3 mm in accordance with the preoperative plan. A no. 20 blunt-side-opening long needle was used to inject the tumescent anesthesia solution (25 ml of 2% lidocaine + 2 mg of adrenaline + 12.5 ml of 8.4% sodium bicarbonate + 1000 ml of normal saline). The amount of tumescent fluid injected depended on the amount of fat required and the range of liposuction. A side-opening liposuction needle with an inner diameter of 3 mm was inserted into the subcutaneous fat layer, a 20 ml syringe was connected, and subcutaneous fat was extracted using the syringe liposuction technique [14,15]. Uniform radioactivity extraction was conducted, and the amount of extracted fat depended on the amount of fat required to fill the subcutaneous tunnels of the scar. The contused tissue around the incision was trimmed, and the skin incision was sutured. The surgical area was bandaged under pressure. The collected fat was statically precipitated and filtered to remove the tumescent anesthetic fluid and was then placed in a 10 ml syringe for use.
