Med J Malaysia, 2011 Jun;66(2):142-3.

Haemorrhage arising from gastric arteriovenous malformation (AVM) is rare and normally occurs in the elderly. Bleeding gastric AVM presenting in the younger age group is even rarer. We report a case of a 14 year old boy who presented with recurrent episodes of haematemesis. He subsequently underwent a proximal gastrectomy and the histological examination confirmed a gastric AVM. After reviewing the literature we believe this is the youngest ever reported case of bleeding gastric AVM reported in English literature.

Spinal arteriovenous malformation presenting with prolapsed intervertebral disc: a diagnostic dilemma

Farina MY, Harunarashid H, Faridzal F, Jegan T, Das S

Clin Ter, 2012 Nov;163(6):491-3.

PMID: 23306743

The availability of multiple investigating modalities should be utilized to arrive at the correct diagnosis of the spinal arteriovenous malformation (AVM). We hereby report the case of a 21-year-old, obese female, who presented with paraplegia and impaired bowel control two years after an episode of the fall. The Magnetic Resonance Imaging (MRI) of her spine not only revealed disc prolapse at T11-T12, but also tortuous dilated spinal veins and cord oedema. A diagnosis of a spinal arterio-venous fistula was confirmed after a spinal angiogram. The dilemma of treating the right pathology for the clinical signs and symptoms are being discussed.

Spontaneous massive haemothorax in the peri-partum period of an undiagnosed neurofibromatosis type 1 patient - A surgical perspective

Narasimman S, Govindasamy H, Seevalingam KK, Paramasvaran G, Ramasamy U

PMID: 30846675

Acute massive haemothorax is a life-threatening situation, which is often associated with a preceding trauma. However, spontaneous haemothorax is a rare occurrence, especially in pregnancy. Spontaneous haemothorax in the immediate post-partum period secondary to a ruptured intercostal AVM is extremely rare more so in the background of an undiagnosed neurofibromatosis. This is a report of a young lady presenting with pleuritis and breathlessness after the delivery of her 1st child. Her management is discussed.

Fulltext Development of pseudo-subarachnoid hemorrhage secondary to hypoxic-ischemic injury due to bleeding pulmonary arterio-venous malformation

Md Noh MSF, Abdul Rashid AM

BMC Neurol, 2018 Sep 28;18(1):157.

PMID: 30266082 DOI: 10.1186/s12883-018-1161-x

BACKGROUND: The computed tomography (CT) finding of a pseudo-subarachnoid hemorrhage (SAH) may lead the treating physician into a diagnostic dilemma. We present a case of a pseudo-SAH in a patient with post-resuscitative encephalopathy, secondary to a newly diagnosed bleeding pulmonary arterio-venous malformation (AVM).

CASE PRESENTATION: A 19-year-old female presented acutely with massive hemoptysis. Cardiopulmonary resuscitation (CPR) followed, and the patient was subsequently intubated for airway protection with intensive care unit (ICU) admission. Urgent CT angiography of the thorax showed a bleeding pulmonary AVM, with evidence of hemothorax. Non-contrasted cranial CT initially revealed cerebral edema. Day 3 post admission, repeat cranial CT showed worsening cerebral edema, with evidence of pseudo-SAH. Patient passed away the next day.

CONCLUSIONS: Pseudo-SAH, if present, carries a poor prognosis. It should be recognized as a potential CT finding in patients with severe cerebral edema, due to various causes. The diagnosis is vital, to avoid wrongful treatment institution, as well as determination of cause of death.

Fulltext Aneurysms are more common than arteriovenous malformations as the cause of subarachnoid haemorrhage in the Malaysian population

Chee CP, Loh TG

Singapore Med J, 1988 Oct;29(5):427-31.

PMID: 3241969

A retrospective prospective study of 84 cases of subarachnoid haemorrhage, 24 intracranial aneurysms and 18 arteriovenous malformations (AVM's) treated in the University Hospital, Kuala Lumpur, during the post CT-scan era was carried out to verify the relative frequencies of these clinical entities in the Malaysian population. Our results show that aneurysms are commoner than arteriovenous malformations as a cause of subarachnoid haemorrhage and also the most frequent as a whole, thus refuting the previous claims that AVM's are 4 to 10 times more common than aneurysms in this part of the world. Of interest was the internal carotid artery aneurysms accounted for half of the anterior circulation aneurysms and that 2/3 of the AVM's presented with intracranial haemorrhage.

Unilateral moyamoya disease with co-existing arteriovenous malformation

Nawawi O, Sinnasamy M, Ramli N

Br J Radiol, 2006 Jul;79(943):e12-5.

PMID: 16823046

A case of an intracerebral bleed in a young man with a rare combination of arteriovenous malformation (AVM) and unilateral moyamoya disease is presented. The location of the bleed in the left basal ganglia corresponded to the area supplied by the basal moyamoya vessels. The AVM which received supply from collateral moyamoya vessels as well as normal cerebral arteries was located in the ipsilateral parieto-occipital region posterior to the basal ganglia bleed. This is the first reported cerebral AVM co-existing with a unilateral moyamoya disease in the English literature. Unusual features of the case such as the unilaterality of the angiographic abnormalities, their coexistence and hypotheses as to their development are discussed.

Calibre persistent submucosal artery of the jejunum: a rare cause of massive gastrointestinal bleeding

Wan Muhaizan WM, Julia MJ, Al Amin D

Malays J Pathol, 2002 Dec;24(2):113-6.

PMID: 12887171

Historically a calibre persistent submucosal artery was most often described in the stomach. However in later years it was also discovered in the duodenum and jejunum. It is an uncommon and important cause of massive gastrointestinal bleeding in which failure of detection and early intervention would lead to death. In this paper we report a 27-year-old man with no significant medical history who presented at the emergency unit for recurrent melaena, haematochezia and hypotension. Initial investigations failed to localize the source of bleeding. Emergency exploratory laporatomy revealed a small jejunal mucosal nodule that was actively spurting blood. Histopathological evaluation identified a calibre persistent submucosal artery.

Fulltext Pulmonary arteriovenous malformation: a rare cause of cyanosis in a child

Sharifah AI, Jasvinder K, Rus AA

Singapore Med J, 2009 Apr;50(4):e127-9.

PMID: 19421665

Pulmonary arteriovenous malformations are rare vascular anomalies. We report a 12-year-old girl who presented with exertional dyspnoea, cyanosis and clubbing since the age of five years, and multiple pulmonary arteriovenous malformations. Computed tomography pulmonary angiogram showed a large pulmonary arteriovenous malformation at the lower lobe of the right lung. Pulmonary angiogram showed a large right lung arteriovenous malformation and two small left lung arteriovenous malformations. The multiple arteriovenous malformations were occluded with Gianturco coils. She is now asymptomatic and on regular follow-up.

Fulltext Challenges in the management of massive intraorbital and hemifacial arteriovenous malformation as causing life-threatening epistaxis

Manuel AM, Kalimuthu S, Pathmanathan SS, Narayanan P, Zainal Abidin Z, Azmi K, et al.

Asian J Surg, 2017 Apr;40(2):158-162.

PMID: 24210537 DOI: 10.1016/j.asjsur.2013.09.011

Arteriovenous malformations are congenital lesions that may evolve with time and manifest in a plethora of presentations. They can occur as torrential epistaxis when it extensively involves the facial region. Multi-imaging modalities are available to assist in characterizing the structure of the lesion as well as its location and extent. This complex disease requires a multidisciplinary team approach with preoperative embolization and surgery. We present a rare cause of life-threatening epistaxis in a gentleman with a longstanding orbital and hemifacial arteriovenous malformation and discuss the complexities involved in its management.
