We present three cases of anomalous origin of the left vertebral artery (LVA) detected during the evaluation of stroke. The VA usually enters the transverse foramen of the sixth cervical vertebra (C6), but an anomalous LVA originating from the aorta frequently enters at a higher level. In our series, ultrasound of the LVA showed entry at C4 in two patients and at C5 in one patient. These findings suggested anomalous LVA origin, and three-dimensional computed tomography demonstrated the LVA arising from the aorta proximal to the left subclavian arteries...

Breast lymphedema (BLE) has been reported as a complication following breast cancer treatment. As for extremity lymphedema treatment, supermicrosurgical lymphaticovenous anastomosis (LVA) is considered an option for the treatment of progressive BLE refractory to conservative treatments, but no case has been reported so far. We report the first case of BLE successfully treated with supermicrosurgical LVA. A 55-year-old female presented with left BLE after breast conserving surgery and axillary lymph node dissection and adjuvant radiotherapy...

The firing pattern of individual neurons is an important element for information processing and storing. During the first weeks of development, there is a transitional period during which CA1 pyramidal neurons display burst-spiking behavior in contrast to the adult regular-firing pattern. Spike after-depolarizations (ADPs) constitute a major factor underlying burst-spiking behavior. Using current-clamp recordings, we studied ADP waveforms and firing patterns in CA1 pyramidal neurons of Wistar rats from 9 to 19 postnatal days (P9-19)...

BACKGROUND: Lymphaticovenular anastomosis (LVA) is a supermicrosurgical procedure that involves the anastomosis of a functional lymphatic channel to a venule. Although peri-operative care might be an important contributor to the success of this technique, evidence about optimal peri-operative care seems limited. This review aims to summarize the peri-operative methods used by authors reporting on LVA. METHODS: A systematic search of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

OBJECTIVE: Lymphoedema of the extremities is a widespread pathological condition that mostly occurs as a complication of cancer resections, especially in women. Conventional therapy refers to conservative and physiotherapeutic approaches. Surgical strategies have been widely reported in the literature and are still challenging. Part of this literature focuses on the supra microsurgical lymphaticovenular anastomosis (LVA) technique. LVA is characterized by a high success rate, minimal invasivity and broad indications...

Aberrant left vertebral artery (LVA) origin off the aortic arch is an uncommon anatomic variant. Treatment of the thoracic aortic pathology that necessitates its coverage has not been described. We present a patient with an acute intramural hematoma with a dominant LVA originating from the aortic arch. A LVA-to-carotid artery transposition with shunt placement, carotid-to-subclavian bypass, and thoracic endovascular aortic repair were performed. The patient recovered uneventfully, without any evidence of stroke...

INTRODUCTION: Left atrium (LA) low voltage area (LVA) on 3-D electroanatomic bipolar voltage mapping (EAVM), as a surrogate for scar, is associated with poor AF ablation outcome. We evaluated the long-term outcome of an LVA-guided atrial fibrillation (AF) substrate modification strategy as an adjunct to pulmonary vein isolation (PVI). METHODS AND RESULTS: Two hundred and one consecutive patients with AF (82% persistent/Non-PAF, age 65 years), who underwent EAVM during AF prior to PVI, were divided into 2 groups according to the presence or absence of LVA outside the PV antra, defined as bipolar voltage of <0...

In atrial fibrillation (AF), left atrial diameter (LAD) and low voltage area (LVA) are intermediate phenotypes that are associated with AF type and progression. In this study, we tested the hypothesis, that these phenotypes share common, genetically-determined pathways using pathway enrichment analysis of GWAS data. Samples from 660 patients with paroxysmal (n = 370) or persistent AF (n = 290) were genotyped for ~1,000,000 SNPs. SNPs found significantly associated with LAD, LVA or AF type were used for gene-based association tests in a systematic biological Knowledge-based mining system for Genome-wide Genetic studies (KGG)...

OBJECTIVE: Our hypothesis is that hypoperfusion of the brainstem is due to elevated vertebrobasilar artery resistance, triggers hypertension. We asked: is there a functional relationship between the sympathetic innervation to the vertebrobasilar system and its remodelling in the SHR? DESIGN AND METHOD: SHRs (11-12 weeks old) received either sham surgery or bilateral SCGx. Animals recovered for 14 days, were then perfused-fixed with 4% PFA and the vertebrobasilar arteries examined using both immunohistofluorecent staining of sympathetic (anti-DβH) and parasympathetic (anti-VAChT) fibres, and by cross sectional examination of vertebral and basilar arteries...

We experienced a rare case of post-infarct left ventricular aneurysm (LVA) and ventricular septal perforation (VSP). An 83-year-old woman was treated for acute cardiac insufficiency. Three weeks later after hospitalization, she had sudden cardiorespiratory failure and was diagnosed with VSP and LVA. She underwent emergency heart surgery. After establishing extracorporeal circulation, the LVA was excised longitudinally from the left side of the left anterior descending branch. Endoventricular patch plasty (Dor procedure) was performed to exclude the ventricular aneurysm, and the VSP was closed using Dacron patch...

Left ventricular aneurysm (LVA) and false aneurysm are complications of acute myocardial infarction, trauma, and cardiac surgery. Left ventricular false aneurysm (LVFA) is a particularly catastrophic complication owing to its high propensity for rupture. Surgical resection should be considered for LVFA occurring within three months after myocardial infarction or development of congestive heart failure. In this report, we describe a case of acute heart failure with LVA and LVFA occurring in stage as a complication of myocardial infarction in a 55-year-old man...

PURPOSE: The atrial conduction time measured by echocardiography using tissue Doppler imaging (TDI) has been reported as a predictive factor of left atrial (LA) remodeling. We investigated the P wave to LA appendage (LAA) conduction time defined by transthoracic echocardiography using TDI (P-LAA TDI), and directly compared the actual LA electrical conduction time determined by the electrophysiological data. Additionally, we confirmed the clinical utility of the P-LAA TDI by examining the relationship to the electroanatomical LA remodeling data...

In this case report we describe the use of a 2-stage approach to treat severe recurrent vulvar lymphangiectasia in a patient with Noonan syndrome. First, 3 functional lymphatic vessels were identified and anastomosed to venules in an end-to-end fashion. Then, in a second surgical procedure, the vulvar lesions were resected as much as possible and the vulva was reconstructed. By the 12-month follow-up the patient had recovered well. Although there were still some small vesicles on the left labia there was no more ooze, itch, and pain...
