INTRODUCTION: A venous lake (VL) is a vascular lesion with common occurrence in many patients, manifested as a dark blue-to-violet compressible papule, caused by dilation of venules. The main reasons for the treatment of VL are aesthetic. The haemorrhaging episodes or impairment of oral normal functions are also under considerations. Treatment of lip VL includes surgical excision, selective photocoagulation, cryotherapy, sclerotherapy and electrodessication. The high-intensity diode laser is an option...

Lateral and sigmoid sinus malformations are uncommon and dangerous anatomical variations that surgeons may encounter when performing a retroauricular approach. We report three cases of rare temporal bone venous sinus anomalies seen in patients who underwent cochlear implant surgery. The first patient had a diagnosis of CHARGE syndrome and presented a bilateral persistent petrosquamosal sinus with sigmoid sinus agenesis, which made mastoidectomy for cochlear implantation difficult. The second patient presented an anomalous venous lake in the occipital region, which communicated the left dural venous sinuses with a conglomerate of pericranial vessels in the left nuchal region, also consistent with left sinus pericranii...

BACKGROUND: The Venous Window Needle Guide (VWING; Vital Access Corp, Salt Lake City, Utah) is a surgically implanted titanium device designed to facilitate cannulation of uncannulatable dialysis access arteriovenous fistulas (AVFs) because of excessive depth, aneurysm formation, or tortuosity but that exhibit sufficient flow volume to support hemodialysis. We report the 18-month fistula patency, functionality, and complications of the use of the VWING device. METHODS: This retrospective study examined AVF patency, VWING functionality, interventions, and device infections at 18 months after VWING implantation...

Venous lake is a benign vascular malformation commonly seen in elderly patients, typically arising in sun-exposed areas of the body. Patients often seek treatment to prevent recurrent bleeding or because they find the lesion cosmetically unacceptable. Venous lake may negatively affect quality of life, due to the cosmetic disfigurement it can create and the resulting psychological distress. Traditional treatments, such as surgical excision, cryosurgery, sclerotherapy, and electrocoagulation, result in varying degrees of success and can cause discomfort...

Rapid ascent to high altitude commonly results in acute mountain sickness, and on occasion potentially fatal high-altitude cerebral edema. The exact pathophysiological mechanisms behind these syndromes remain to be determined. We report a study in which 12 subjects were exposed to a FiO2 = 0.12 for 22 h and underwent serial magnetic resonance imaging sequences to enable measurement of middle cerebral artery velocity, flow and diameter, and brain parenchymal, cerebrospinal fluid and cerebral venous volumes...

New advances have been pioneered in the pathogenesis,clinicopathological features,and treatment of oral venous lakes. It is concluded that oral venous lakes can be classified as a venous malformation,and multidisciplinary approaches (in particular the involvement of department of dermatology and department of ear,nose and throat) may be adopted to achieve better management of this disease.

INTRODUCTION: Sinus pericranii is a rare vascular anomaly. It is characterized by abnormal communication between the extracranial and intracranial venous system, usually involving the superior sagittal sinus and occasionally the transverse sinus. Off the midline lesions are extremely rare. Multiplicity, associated venous lakes, venous angioma and lateral location are unusual and unique presentation of sinus pericranii. CASE REPORT: A case of multiple congenital off-midline sinus pericranii in the left frontotemporal and parietal region is presented...

Beaked whales are a poorly known but diverse group of whales that have received considerable attention due to strandings that have been temporally and spatially associated with naval sonar deployment. Postmortem studies on stranded carcasses have revealed lesions consistent with decompression sickness, including intravascular gas and fat emboli. These findings have been supported by analyses of intravascular gas emboli showing composition dominated by nitrogen gas. To increase our understanding of the pathophysiology of nitrogen bubble formation and intravascular embolization, we examined the gross and microscopic anatomy of the venous system in the head of beaked whales...

BACKGROUND AND OBJECTIVE: Different subspecialists treat benign intraoral lesions using various approaches including surgical excision, medical therapy, sclerotherapy, and laser photocoagulation. The goal of this study was to establish whether lasers could effectively target and destroy oral lesions containing endogenous chromophores, while minimizing injury to unaffected adjacent tissues and critical structures. MATERIALS AND METHODS: This retrospective study involved 26 cases of benign oral lesions, both vascular and pigmented, which were addressed by means of selective laser treatment...

BACKGROUND: Hepatic decompensation in cirrhosis heralds an accelerated course with poor survival. An increase in hepatic venous pressure gradient (HVPG), rather than surrogate tests of liver function, appears to be the sole predictor of decompensation after surgical resection. We propose that hepatic sinusoidal walls become less elastic as cirrhosis progresses. Decompensation signals the development of increased vessel wall rigidity. The pressure-flow characteristics then become subject to Hagen-Poiseuille's law, which applies only to rigid, cylindrical vessels...

Calibre persistent labial artery (CPLA) usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a mucocele, haemangioma, venous lake, varix or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. Here, we report a case of a 25-year-old woman with no previous relevant medical history who presented with a complaint of an asymptomatic, non-ulcerated, progressively growing nodule (over the last 5 months) on the upper lip. In this case, the diagnosis was made clinically and confirmed by immunohistochemical analysis...

PURPOSE: The insertion of tunneled central venous access catheters (CVCs) in infants can be challenging. The use of the ultrasound-guided (UG) approach to CVC placement has been reported in adults and children, but the technique is not well studied in infants. SUBJECTS AND METHODS: A retrospective review was performed of infants under 3.5 kg who underwent attempted UG CVC placement between August 2012 and November 2013. All infants underwent UG CVC placement using a standard 4...

Here we report a case of thymic cavernous haemangioma with the left innominate vein aneurysm. A 43-year-old man presented with chest pain. Enhanced chest computed tomography revealed an anterior mediastinal tumor measuring 60 × 52 × 38 mm with multiple venous lakes and focal specks of calcification, composed of a low-density soft tissue mass along with a left innominate vein aneurysm. We preoperatively diagnosed the mass as a thymic hemangioma and subsequently performed surgical resection. Pathologic diagnosis was a thymic cavernous hemangioma with a left innominate vein aneurysm, which is very rare...

We describe here a child with angiodysplasia of the small intestine, diagnosed by double-balloon endoscopy (DBE), who was treated with transumbilical single-incision laparoscopic surgery (T-SILS). A 9-year-old boy presented to another hospital with intermittent fresh melena of a duration of 5 months and 4 days. Anoscopy and gastric mucosal membrane scintigraphy were unsuccessful diagnostically, and he was referred to our hospital for further examination and treatment. Under general anesthesia, we performed DBE by an anal route, with the ileum assessed for a distance of about 150 cm from the ileocecal valve...

BACKGROUND: Animal studies have demonstrated that functional immune responses, as determined by the levels of CD4(+) cell counts and anti-schistosome antibodies responses, determine the efficacy of praziquantel. Based on this evidence, it has been hypothesised that the immunodeficiency effects of the human immunodeficiency virus (HIV)-1 infection may affect the efficacy of praziquantel in co-infected human hosts. Thus, the present study assessed the efficacy of praziquantel by comparing parasitological cure rates and the reduction in infection intensity in HIV-1 seronegative individuals infected with S...

The onset of hepatic decompensation in cirrhosis heralds an accelerated downhill course with poor outcome. The sole predictor of this decompensation in cirrhosis is increased hepatic vein to portal vein gradient hepatic venous pressure gradient (HVPG). Surrogate markers of liver function or hepatic reserve appear to be less relevant. The hepatic sinusoids become less elastic and more rigid as liver fibrosis and cirrhosis progress. We propose that the Hagen-Poiseuille's law, which applies to rigid, but not elastic vessels, determines the pressure-flow characteristics in the sinusoids...
