BACKGROUND: The method of lymphatic venous anastomosis (LVA), including its indications or preoperative examinations, has not been established. The purpose of this study is to reveal the possible application of preoperative echography in surgical LVA outcome. METHODS: We performed a retrospective case-control study on patients with lower limb lymphedema who underwent LVA between August 15, 2013 and August 15, 2014. As a preoperative examination, we used venous echography to identify subcutaneous veins in the echo group, while we only used Accuvein visualizing system in the control group...

BACKGROUND: Identification of functional lymphatic vessels and localization of lymphatic vessels are important for lymphaticovenular anastomosis (LVA). Indocyanine green (ICG) lymphography is useful for localization of superficial lymphatic vessels where dermal backflow is not observed, but not for lymphatic vessels in deep layer or where dermal backflow is observed. Ultrasound has been applied in LVA and is considered useful for localization of lymphatic vessels with ICG lymphography cannot be visualized...

We herein present a case of distal aortic arch aneurysm with an isolated left vertebral artery(LVA). In surgery, after establishing cardiopulmonary bypass, the LVA was anastomosed to the left common carotid artery (LCCA) while under moderate hypothermia. Selective cerebral perfusion (SCP) was then initiated by inserting catheters into the brachiocephalic artery( BCA), the LCCA and the left subclavian artery (LSA). The aorta was transected between the BCA and the LCCA, and an open stent graft was deployed into the descending aorta during circulatory arrest...

Voltage-gated calcium (CaV) channels are widely expressed and are essential for the completion of multiple physiological processes. Close regulation of their activity by specific inhibitors and agonists become fundamental to understand their role in cellular homeostasis as well as in human tissues and organs. CaV channels are divided into two groups depending on the membrane potential required to activate them: High-voltage activated (HVA, CaV1.1-1.4; CaV2.1-2.3) and Low-voltage activated (LVA, CaV3.1-3.3)...

Aims: Atrial fibrillation (AF) is associated with thromboembolic events. Currently, the CHA2DS2-VASc score is recommended for thromboembolic risk stratification in non-valvular AF patients. However, recent data suggested a potential role of atrial remodelling on thromboembolism. This study aimed to assess the association between left atrial low-voltage area (LVA) and history of clinical manifest as well as subclinical silent cerebral ischaemia (SCI) in AF patients. Methods and results: Two-hundred patients [64 ± 10...

INTRODUCTION: Lymphedema is a chronic condition caused by the obstruction or impairment of lymphatic fluid transport resulting in irreversible skin fibrosis. Besides conservative therapy, surgical techniques for lymphedema including liposuction, lymphatico-lymphatic bypass, lymphovenous anastomosis (LVA), and vascularized lymph node transfer (VLNT) are options with increasing popularity in the recent past. In our review, we investigated the efficacy of LVA for the treatment of lymphedema...

INTRODUCTION: Supermicrosurgical lymphatic-venous anastomosis (LVA) can improve limbs lymphedema. We describe a technique that we employ for preoperative lymphatic mapping of the upper limb (UL), when indocyanine green (ICG) lymphography shows only dermal backflow (DB) and no lymphatic vessel is detectable. PATIENTS AND METHODS: Sixteen patients undergoing LVA for unilateral UL lymphedema, showing "stardust" or "diffuse" DB pattern, were included. Demographic, clinical data, and limbs measurements were recorded...

Lymphaticovenous anastomosis (LVA) is primarily performed for lymphedema of the lower extremities after surgical treatment of gynecologic cancer and lymphedema of the upper extremities after surgical resection of breast cancer; however, LVA for lymphedema due to malignant lymphoma has not been reported to date. We herein present a patient with severe lymphedema of the lower extremities due to refractory malignant lymphoma, which markedly improved with LVA. LVA could contribute to improve quality of life in patients with end-stage disease with lymphedema of the lower extremities due to refractory malignant lymphoma...

Left ventricular aneurysm (LVA) is an abnormal dilated heart structure, either congenital or acquired. LVA is a rare cardiac condition with no symptoms in most cases, thus occasionally diagnosed during investigations of other diseases. Its association with certain cardiac complications and sudden cardiac deaths has been reported. However, its role as a cause of sudden unexpected death is rare. The author reported a sudden cardiac death in a 29-year-old man with LVA. Without a significant coronary artery disease and known etiologies of LVA, such an abnormal heart structure in the present case was considered congenital LVA...

BACKGROUND: Patients with secondary lower extremity lymphedema (LEL) often develop suprapubic lymphedema. We developed a novel surgical method of shaping the lower abdomen and debulking suprapubic lymphedema with simultaneous reconstruction of lymphatic flow in case of LEL. METHODS: A skin incision in a fleur-de-lis pattern was performed for horizontal and vertical abdominal skin and fat resection. A caudal-based isosceles triangular flap was created on the central suprapubic region to reduce wound tension at the intersection of the horizontal and vertical incisions...

Anatomy is the keystone to an appropriate understanding of surgical and radiological sciences. Here the authors report on a rare case of complete right- and left-sided thoracic ducts (TDs) associated with aberrant left-vertebral artery (LVA) arising from the aortic arch. The TDs originated from right and left cisterna chyli and terminated separately close to the left venous angle. Superior to the aortic arch, the TDs showed different relationships to the LVA; the right TD was ventral, while the left was dorsal in position...

Ventricular outpouching is a rare finding in prenatal sonography and the main differential diagnoses are diverticulum, aneurysm, and pseudoaneurysm in addition to congenital cysts and clefts. The various modes of fetal presentation of congenital ventricular outpouching include an abnormal four-chamber view on fetal two-dimensional echocardiogram, fetal arrhythmia, fetal hydrops, and pericardial effusion. Left ventricular aneurysm (LVA)/nonapical diverticula are usually isolated defects. Apical diverticula are always associated with midline thoracoabdominal defects (epigastric pulsating diverticulum or large omphalocele) and other structural malformations of the heart...
