Presentation
Ca se Presentation: TW is a 66 year old right handed white male who presented with a 6 months history of progressive lower extremity weakness. [medschool.lsuhsc.edu]
We present a case of PAVM, which was picked up on a chest X-ray done in a patient with hemoptysis who presented to the emergency department (ED) of a Medical College Hospital in South India. [jacpjournal.org]
Case Report: We present a 50 year old woman who presented with acute onset left sided weakness. Her vitals including blood pressure were noted to be normal on presentation. CT head revealed a right parietal lobar ICH. [neurology.org]
Due to the rarity in presentation as well as infrequent reports, there are no specific guidelines to diagnose and manage them. [saudisurgj.org]
The first patient presented with episodes of left extremity weakness and numbness as well as chronic headaches. The second patient presented with spontaneous intracerebral hemorrhage. [jnis.bmj.com]
Entire Body System
- Fever
He was not on regular follow-up for RHD and refused any history of fever. [jacpjournal.org]
She also complained of low grade fever, breathlessness, and fatigue. Examination revealed an emaciated, anemic, centrally cyanosed girl with weight and height below 5th percentile. Oxygen saturation was 84% and respiratory rate 24/min. [frontiersin.org]
There was neither any history of trauma nor any associated features of pain or fever. Patient was of normal built for his age and sex, and systemic examination was unremarkable. [contempclindent.org]
Gastrointestinal
- Constipation
Depending on the location of a vascular malformation and the structures it affects, it can also cause constipation, pelvic pressure, or swelling in the limbs. [nyulangone.org]
Cardiovascular
- Thrombosis
The obvious cause of the pain was the torsion and secondary ischemia and thrombosis of the abdominal polypoid neoplasm. The extirpation of the neoplasm and partial resection of the greater omentum was done. [pubs.sciepub.com]
Secondary changes include atherosclerosis, focal thrombosis, secondary dystrophic calcification, organisation and mild inflammation [ 15 ]. [omicsonline.org]
These vascular spaces showed evidence of thrombosis with patchy dystrophic calcification and well-developed phlebolith [Figure 3] d and f]. [contempclindent.org]
They do not have any systemic associations but are prone to thrombosis and hyphema. On microscopic examination, they appear as dilated vascular channels and often have a central thrombus. [eyewiki.aao.org]
In some cases, fresh or older calcified blood clots ( thrombosis ) may be detected. Ultrasound evaluation of arteriovenous malformations also shows evidence of shunting of blood between the affected artery and vein with turbulent blood flow. [dermnetnz.org]

Skin
- Eruptions
This may occur spontaneously or during traumatic procedures such as dental extractions, tooth eruption or biopsy [ 8 ]. The origin and pathogenesis of AVMs still remains largely unknown. [omicsonline.org]
Workup
Initial laboratory workup showed hemoglobin (Hb): 11.3 g/dl, hematocrit (HCT): 35.7%, white blood cells (WBC): 6.1 × 10 9 (PMN: 57.4%, L: 34.5%), Platelets: 306 × 10 9 ; all within the normal range. [frontiersin.org]
Approximately 50% are located in the craniofacial region with those in the head and neck region being far less common than the intracranial AVMs. [1], [2] Magnetic resonance imaging is considered as the gold standard for workup of a malformation [6] and [amhsjournal.org]
Treatment
Not all aneurysms require treatment and for aneurysms that require treatment, multiple options need to be considered. [massgeneral.org]
What Is the Treatment for Arteriovenous Malformations? The treatment team typically consist of a neurologist, neuroradiologist, neuropsychologist, neurosurgeon and anesthesiologist; a careful evaluation is key to successful treatment. [luriechildrens.org]
It is frequently combined with the other treatments such as radiation or surgery. Radiation Treatment This treatment is also known as Radiosurgery or Stereotactic Radiotherapy. [brainavm.uhnres.utoronto.ca]
Our Approach to Treatment Houston Methodist vascular experts at the Vascular Malformation Clinic are dedicated to giving arteriovenous malformation (AVM) patients the long-term, multi-procedure treatments they often need. [houstonmethodist.org]
What is the best treatment for a dural fistula? The best treatment is usually endovascular surgical blocking of the abnormal connections that have caused the fistula. [strokeassociation.org]
Prognosis
Treatment and prognosis Treatment options include: trans-catheter coil embolization surgery (historically treated with surgery) Once successfully treated (embolotherapy, surgical resection), prognosis is generally good for an individual lesion. [radiopaedia.org]
Prognosis Iris AVMs carry very little risk for morbidity or mortality and thus confer an excellent prognosis. BSCS Section 2. Fundaments and Principles of Ophthalmology BSCS Section 4. [eyewiki.aao.org]

Etiology
As to the etiology of the AVM in this instance, there was a concern prior to hysterectomy for an AVM. Given the eventual diagnosis of arteriovenous fistula, this idea was again examined. [gynecology-obstetrics.imedpub.com]
No common etiological factors for the disease were found, which makes it very difficult to understand how the two disease processes occurred together in our patient. [frontiersin.org]
Etiology of the hemorrhage was deemed to be cryptogenic. A month later she improved to modified Rankin Scale (mRS) of 0. Three months later, she presented again with left sided weakness. [neurology.org]
Etiology The etiology of vascular malformations of the spinal cord has not been clearly defined. Intradural parenchymal malformations arise in a younger patient population and are believed to be congenital. [emedicine.medscape.com]

[…] coils, particles, acrylates, or polymers introduced by a radiographically guided catheter, may be used in addition to neurosurgery or radiosurgery, but is rarely successful in isolation except in smaller AVMs. [15] Gamma knife may also be used. [16] Epidemiology [en.wikipedia.org]

In contrast, congenital malformations increase in size as the child grows. [13] According to their pathophysiology and vascular architecture low flow and high flow malformations are distinguished. [faoj.org]

Prevention
Managing high blood pressure, avoiding medications that thin the blood, and keeping regular appointments with a neurologist can also help monitor your condition and prevent complications. [healthline.com]
This blocks blood flow from entering into the aneurysm, preventing future rupture. [massgeneral.org]
During the operation, the doctors clipped the aneurysms and excised AVM to prevent further bleeding. [deccanchronicle.com]
Treatment Accurate diagnosis of PAVMs followed by prompt intervention is essential to close the abnormal connection and prevent potentially serious complications. [medstargeorgetown.org]
Knowledge gained from these studies provides the foundation for understanding how problems can occur, offering hope for new means to treat and prevent congenital disorders including AVMs. [my.clevelandclinic.org]
