Lymphatic-venous anastomosis for the treatment of refractory lymphatic ascites following radiation therapy: A case report.

Radical treatments for intra-abdominal malignancies disturb physiological lymphatic drainage and predispose the patients to lymphatic complications such as lymphatic ascites. Despite its infrequent occurrence, lymphatic ascites is a morbid complication, and a definitive treatment protocol for refractory cases has not been established. Surgical treatments are opted depending on the etiology, symptoms, and facility equipment. Lymphatic-venous anastomosis (LVA) bypasses the proximal lymphatic blockages and provides an alternative route for lymphatic fluid recirculation into the venous system, thereby improving the lymphatic congestion. Herein, we report the utility of LVA surgery in the treatment of refractory serous lymphatic ascites that developed after radiation therapy for cervical cancer in a 77-year-old woman. The patient had massive ascites and suffered from abdominal distention and anorexia for 1 year. The ascites was unresponsive to conservative treatment. Under local anesthesia, eight incisions were made in the lower extremities just above the lymphatic channels that were identified by indocyanine green lymphography, and a total of 14 LVAs were created. The postoperative course was uneventful, and the ascites improved significantly. The patient remained free from the recurrence of ascites during 3.5 years of postoperative follow-up. LVA surgery was effective for the improvement and long-term control of lymphatic ascites. This procedure may be a viable option for the management of lymphatic ascites.

A case of a superficial circumflex iliac perforator-intercostal artery perforator (SCIP-ICAP) compound flap for necrotizing soft tissue infection.

Even in NSTI patients with many comorbidities, it is possible to save both the life and the limb by thorough debridement and suitable reconstruction. SCIP-ICAP compound flap can be versatile for a massive defect of an upper extremity. A Case of a Supercharged Compound Flap for Necrotizing Soft Tissue Infection.

Lymphatic Malformation Treated with Lymphatic Malformation-Venous Anastomosis Under Local Anesthesia.

Lymphatic malformation (LM) can occur in the head and neck regions and cause cosmetic problems in adults. Sclerotherapy and surgical resection have been frequently applied; however, both are far from being minimally invasive in terms of aesthetic satisfaction, including the aesthetic downtime. We performed a less-invasive treatment using the venous anastomosis technique, named the lymphatic malformation-venous anastomosis (LMVA), mainly in pediatric patients with intractable microcystic lesions, in whom general anesthesia was required because the pediatric patients could not remain still. Here, we report the case of a 35-year-old man with a cystic submandibular LM successfully treated with LMVA under local anesthesia. He presented with a gradually enlarging LM on the neck. For improving aesthetics, LMVA was planned under local anesthesia. Lymphography by injecting indocyanine green revealed no inflow or outflow connection to the malformation; thus, we created an outflow bypass using the sidewall of the LMVA technique. The patient was discharged on the following day of the operation without any postoperative complications. A volumetric analysis 6 months later showed a 43.5% reduction of the malformation, with the patient being completely satisfied with the result. To the best of our knowledge, there has been no previous report on performing LMVA under local anesthesia in an adult. LMVA can be a novel treatment of choice when other options are less feasible.

Combination of Dual Wavelength Picosecond and Nanosecond Pulse Width Neodymium-Doped Yttrium-Aluminum-Garnet Lasers for Tattoo Removal.

BACKGROUND AND OBJECTIVES: Tattoo removal by laser has been mostly performed using Q-switched laser, which has nanosecond pulse width. In recent years, the efficacy of treatment with picosecond pulse width laser has also been reported. STUDY DESIGN/MATERIALS AND METHODS: Using a picosecond-domain, neodymium-doped yttrium-aluminum-garnet laser with a potassium-titanyl-phosphate frequency-doubling crystal, we performed a retrospective clinical study with combination treatment using pulse widths of 750 ps and 2 ns. The number of treatments was compared with the Kirby-Desai score. Tissue changes immediately after laser irradiation at 2 ns and 750 ps were compared using an electron microscope. RESULTS: The combination treatment using pulse widths of 2 ns and 750 ps was safe and more effective than the Q-switched neodymium-doped yttrium-aluminum-garnet laser treatment. Tattoo removal was possible with significantly fewer treatment numbers than the Kirby-Desai score, without adverse events. The results from the scanning electron microscope revealed that ink particles irradiated by 750 ps were more dispersed than those by 2 ns. CONCLUSIONS: The combination treatment with pulse widths of 2 ns and 750 ps and 1064 nm and 532 nm wavelengths using the neodymium-doped yttrium-aluminum-garnet laser was safe and effective and can be a useful option for tattoo removal.

Use of the Distal Facial Artery (Angular Artery) for Supermicrosurgical Midface Reconstruction.

BACKGROUND: In free-flap reconstruction of the midface, options for the recipient artery are quite limited; the superficial temporal artery and the facial artery are the most commonly used arteries. We report our approach for the use of the angular artery (the terminal branch of the facial artery) as the recipient artery in free-flap reconstruction of the midface. METHODS: Nine patients with midface defects underwent free-flap reconstructions using the angular artery as the recipient artery. Identification and marking of the facial artery were performed preoperatively using handheld Doppler ultrasound. The angular artery was located through an incision made on the side of the nose. When present, a vena comitans of the facial artery or any subcutaneous vein in the vicinity of the defect was used as the recipient vein. In other cases, the facial vein in the submandibular region was chosen as the recipient vein, using a vein graft. RESULTS: The average diameter of the angular artery was 0.9 mm (range, 0.7-1.0 mm). In all cases, arterial anastomosis was performed in an end-to-end fashion, and flaps survived completely. In 4 cases, a vein graft was used to bridge the pedicle vein and the facial vein. CONCLUSIONS: Although supermicrosurgical skills may be required for its anastomosis, the angular artery is an anatomically consistent artery, which is suitable for use as the recipient artery in free-flap reconstruction of the midface. Use of the angular artery as the recipient artery allows shorter flap pedicles and decreases the number of vein grafts necessary.

Monitoring free flap venous congestion using continuous tissue glucose monitoring: A case report.

Blood glucose levels (BGLs) are a good indicator of postoperative venous congestion caused by a thrombus at the anastomotic site of a free flap. Tissue glucose levels (TGLs) are believed to be superior to BGLs for two reasons: TGLs are thought to represent a tissue's congestive status more directly than BGLs and are able to be measured by a continuous tissue glucose monitoring device (CTGMD), whereas BGLs must be measured manually by sampling the flap, hindering the patient's sleep and increasing the nurse's workload. A case is described in which a postoperative thrombus developed in a free flap vein three times. TGL in the flap was monitored by a CTGMD (Free Style Libre®, Abbott, U.S.A.), and BGL was monitored in parallel by conventional sampling of the flap. When venous congestion developed at the anastomotic site, TGLs decreased faster than BGLs; after the congestion was ameliorated by exsanguination, BGLs increased faster than TGLs, indicating that TGLs are a better indicator of venous thrombosis at the anastomotic site than BGLs.
