“…There are infrequent reports described in literature about AVFs between extracranial arteries and sinuses of the dura mater [8]. This configuration results in raised blood pressure in the affected sinus and internal jugular vein [6].…”

We present a case of patient with a rare vessel pathology -arteriovenous fistula (AVF) of superficial temporal artery and vein. The 56-year-old man was admitted to the Department of Neurology because of a headache in the right temporal region with concomitant buzzing sound in his right ear. The pain was present mainly in the evenings and was stronger when touching the temporal region. He denied having any head injury in the last few years. There were no signs of central nervous system involvement in the neurological examination. Within the right temporal area a subcutaneous mass with redness of the surrounding skin and with palpable and audible pulsatile thrill was observed. In computed tomography (CT) of the head no abnormalities were found. In duplex-Doppler ultrasound examination of carotid arteries the systolic blood velocity in the right external carotid artery was over two times higher than in the left one. Its flow profile was turbulent and low-resistant. In CT angiography (CTA) an AVF between superficial temporal artery and vein was revealed -it was located at the level of the right zygomatic arch. In both CTA and magnetic resonance angiography, no abnormal connections between extra-and intracranial vessels were found. The patient underwent surgery with good result -all the symptoms disappeared. AVFs of vessels of the scalp are rare and their aetiology is mainly traumatic or iatrogenic. By describing this case we wanted to draw attention to less frequent causes of headache. (Folia Morphol 2019; 78, 4: 879-882)

“…10 The failure of the embryonic vasculature to differentiate into arteries and veins results in a persistent communication between aberrant vessels, with the absence of an intervening capillary bed. 8,11 Trauma, pregnancy, and hormonal changes can cause growth of the lesion and worsening of symptoms. 12 A role of vascular endothelial growth factor was also proposed but remains to be confirmed.…”

Background Arteriovenous malformations (AVMs) of the scalp are rare and infrequently encountered by the neurosurgeon. Case Description We report a unique case of a 42-year-old patient who presented with a progressive worsening of visual acuity in the right eye (lower quadrantanopia) and palpebral ptosis. Physical examination revealed a right exophthalmos and a right frontoparietal scalp soft swelling when the patient was in the supine position. Neurologic work-up showed a scalp AVM extending into the orbit and connected to an intraorbital cavernous angioma. The patient was treated with a frontotemporal craniotomy and decompression of the orbit. Conclusions In the rare case of intraorbital extension of a scalp AVM, neurologic symptoms may appear when the size of the vascular malformation increases with age. The aims of surgery should be decompression of the orbit and aesthetic preservation, rather than complete excision. A review of the literature is also provided.

“…The malformation is not easy to identify because it is not a frequent one 2,6,7,8,9,10,11,12,15,16,19,20 ; sometimes it could remain unknown to the specialists in plastic, aesthetic and reconstructive surgery. In the literature there are few published papers on treatment of the subcutaneous arteriovenous malformations of the sculp.…”

SummaryThe aim of this study is to show the various possibilities to treat this rare malformation, accentuating the results of the early surgical treatment before complications. material: The authors present 8 cases of patients with subcutaneous arteriovenous malformations, 5 females and 3 males (age of 7, 13, 19, 23, 27, 52 and 58 years) treated in the period of 1999 until 2015 at the Clinic for Neurosurgery and the Clinic for Plastic, Aesthetic and Reconstructive Surgery in Skopje, Republic of Macedonia. This malformation has been observed by the parents in the childhood, around the age of 3 years in all cases. Local red circonscripted nodule, soft, with manually discharging tendency and varicose dilated veins have been observed in all cases, deaf on both sides in one case, while in the older case, a cavernous sinus thrombosis caused unilateral exophthalmia, hyaline indurated ophthalmic vein, vertigo, arrhythmia, heart failure and bradypsychia have been observed. The size of the malformation has been from 2.5 to 7 cm. The diagnostics was done using CT, CT-angiography and digital angiography including external carotid angiography. Endocranial arterials peduncle was present in all cases. results: Six cases underwent surgery, while two cases were treated with several treatments of endovascular embolization. The follow up has been ranged from 2 to 15 years. All surgically treated patients improved without recurrence, the exophthalmia, bradypsychia and the heart problems regressed, while in patients treated with endovascular non-complete occlusion the AVM decreased, but still remained. In conclusion: The Surgical treatment remains a first option if it is possible, and as earlier as possible, while embolization is a useful tool in cases where a complete excision is not possible.
