Esophageal varices sometimes Valsalva Varizen oesophageal varices are extremely dilated sub-mucosal veins in the lower third of the esophagus.

Esophageal varices are typically diagnosed through an esophagogastroduodenoscopy. The upper two thirds of the esophagus are drained via the esophageal veinswhich carry deoxygenated blood from the esophagus to the azygos veinValsalva Varizen, which in turn drains directly into the superior vena cava.

These veins have no part in the development of esophageal varices. The lower one third of the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein coronary veinwhich in turn drains directly into the portal vein. This means that collateral circulation develops in the lower esophagusabdominal wall, stomachand rectum.

The small blood vessels in these areas become distended, becoming more thin-walled, and appear as varicosities. In situations where portal pressures increase, such as with cirrhosisthere is dilation of veins in the anastomosisleading to esophageal varices.

Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure, Valsalva Varizen. Splenectomy can cure the variceal bleeding due to Valsalva Varizen vein thrombosis.

Varices can also form in other areas of the body, including the stomach gastric varicesduodenum duodenal varicesand rectum rectal varices. Treatment of these types of varices may differ. In some cases, schistosomiasis also leads to esophageal varices. In ideal circumstances, Valsalva Varizen, patients with known varices should receive treatment to reduce their risk of bleeding.

The effectiveness of this treatment has been shown by a number of different studies. When medical contraindications to beta-blockers exist, such as significant reactive airway disease, then treatment with prophylactic endoscopic variceal ligation is often performed. In emergency situations, care is directed at stopping blood loss, maintaining plasma volume, correcting disorders in coagulation induced by cirrhosis, and appropriate use of antibiotics such as quinolones or ceftriaxone.

Blood volume resuscitation should be done promptly and with caution. Resuscitation of all lost blood leads to increase in portal pressure leading to more bleeding. Volume resuscitation can also worsen ascites and increase Valsalva Varizen pressure, Valsalva Varizen. Therapeutic endoscopy is considered the mainstay of urgent treatment, Valsalva Varizen.

The two main therapeutic approaches are variceal ligation or banding and sclerotherapy. In cases of refractory bleeding, balloon tamponade with a Sengstaken-Blakemore tube may be necessary, usually as a bridge to further endoscopy or treatment of the underlying cause of bleeding usually portal hypertension. Esophageal devascularization operations such as the Sugiura procedure can also be used to stop complicated variceal bleeding. Methods of treating the portal hypertension include: Valsalva Varizen supplementation is not necessary if the patient is not eating for four days or less.

Terlipressin and octreotide for 1 to 5 days have also been used. Dilated submucosal veins are the most prominent histologic feature of esophageal varices. The expansion of the submucosa leads to elevation of the mucosa Valsalva Varizen the surrounding tissue, Valsalva Varizen, which is apparent during endoscopy and is a key diagnostic feature. Evidence of recent variceal hemorrhage includes necrosis and ulceration of the mucosa. Evidence of past variceal hemorrhage includes inflammation and venous thrombosis.

Orbital venous varix OVV is an uncommon vascular malformation which is composed of enlarged single or multiple tubular venous channels with direct communication to the systemic venous system. Orbital venous varices are divided into primary and secondary. Primary orbital varices are idiopathic and most likely congenital. They are confined to the orbit. Secondary orbital venous varices are those that are acquired due to increased blood flow as a result of intracranial arteriovenous malformationscaroticocavernous fistuladural arteriovenous fistulaValsalva Varizen, etc.

Secondary varix occurs in association with VGAMs and occasionally with venous angiomas. There may be isolated segmental saccular or fusiform dilatation of cortical veins, Valsalva Varizen. Orbital varix is a tödlich für Krampfadern entity, accounting for less than 1.

Although it is believed to be congenital, and thus present at birth, patients typically do not become symptomatic until later childhood or early adulthood years of age. Cases have however been reported at essentially any age 2. The protracted distension can actually create more room for the globe to fall back into when not distended leading to paradoxical enophthalmos when at rest 1.

Presentation may also be due to a complication. Orbital venous varices are the most common causes of intraorbital haemorrhage. They may also become acutely symptomatic if they thrombose. In such cases, patients report acute onset of retro-orbital pain, Valsalva Varizen, proptosis and decreased visual acuity Rarely, larger lesions involving the superior ophthalmic vein may present as a lacrimal region mass 3.

There is a reported association Valsalva Varizen venous anomalies intracranially which may or may not directly communicate with the Valsalva Varizen 1. Without provocative examination Valsalva manoeuvre they can be very difficult or impossible to diagnose, as the varix may completely collapse. Contrast enhanced studies will demonstrate venous phase opacification with enlargement and possibly proptosis on straining. As with the rest of head and neck imaging, plain films have little if any role in modern radiology.

If performed, Valsalva Varizen, however, the presence of calcified phleboliths are characteristic 1. Ultrasound is an excellent non-invasive modality for assessment Valsalva Varizen the orbit and can be performed easily with various dynamic manoeuvres e, Valsalva Varizen. Valsalva manoeuvre and in various positions e. Additionally, Valsalva Varizen, colour Doppler can Valsalva Varizen give an insight into the flow dynamics of a vascular lesion. In upright posture and at rest no abnormality may be seen.

On straining, venous channels dilate and are associated with increased blood flow. Proptosis may be visible 2. If the diagnosis is suspected contrast CT should be performed both at rest and with a Valsalva manoeuvre, as in some instances no abnormality is visible on routine imaging, and change in size is helpful in distinguishing this entity from other vascular lesions of the orbit.

Non-contrast orbital scan may demonstrate phleboliths. Contrast should be administered Valsalva Varizen the Valsalva phase. The varix will appear as Valsalva Varizen irregular or smooth enhancing lesions which has significantly increased in size with straining, typically located at the orbital apex 2, Valsalva Varizen.

Enhancement should match that of other venous structures e. In the setting of thrombosis, the enhancement may be absent, Valsalva Varizen, and no change on Valsalva manoeuvre will be nach der Geburt Krampf Labia. MRI should also Valsalva Varizen performed with Valsalva or straining, although acquisition time being longer than CT, some patients may find it Valsalva Varizen. The anterior part of the varix can usually be relatively easily excised surgically if thrombosed but may be difficult to identify in a supine patient if no thrombosis is present 2.

Subtotal excision may result in recurrence, and repeat treatment is often more complicated. Ideally, the vein should be resected or clipped as far back towards the orbital apex as possible 3. Catheterisation of the varix may be performed either endovascular route via jugular vein and cavernous sinus or directly after surgical exposure. An orbital venous varix without thrombosis has a limited differential if dynamic views have been performed.

Other orbital vascular lesions to be considered in the differential include:. It should be noted that there is confusion and controversy in the literature as to the precise definitions Valsalva Varizen orbital vascular malformation with a venous component e, Valsalva Varizen. When thrombosis has occurred the differential is broader and is essentially that of an orbital mass:, Valsalva Varizen.
