Argon laser radiation is used to treat congenital and acquired vascular lesions of the head and neck. Thirteen patients requiring a total of 36 treatments were followed up for a minimum of 1 year to assess the response of the vascular lesion to argon ion radiation. Of the 13 patients, 10 had an excellent result, with the lesion no longer being identifiable. Three of the patients had residual but minimal color remaining in the lesion. There were no complications or hypertrophic scars after 1 year of follow-up. The laser parameters used and the surgical technique followed are outlined.

Abstract Background The purpose of this study was to clarify whether the intrinsic depth of midbrain cavernous malformations (MCMs) influenced the surgical outcome. Methods The authors conducted a retrospective study of 76 consecutive patients who underwent microsurgical resection of a MCM. The vascular lesions were categorized into 4 distinct groups based on how these lesions had altered the brainstem surface. Additionally, it was verified whether the actual aspect of the brainstem surface could be predicted only by evaluating the pertinent preoperative MRI slices. Clinical outcome was assessed by determining the modified Rankin Scale Score (mRS) before and after surgery. Results Twenty-three MCMs (30.3%) were located deeply within the midbrain. The overlying midbrain surface appeared to be normal (group nl). In 33 patients (43.4%), the midbrain surface showed only a yellowish discoloration (group yw). In another 14 individuals (18.4%), the midbrain surface was distorted by the underlying MCM and bulging out while the vascular lesion still remained covered by a thin parenchymal layer (group bg). In the smallest group comprising 6 patients (7.9%), the exophytic MCM had disrupted the midbrain surface and was clearly visible at microsurgical exposure (group ex). The mean mRS decreased in the group nl from 1.43 preoperatively to 0.61 at follow-up. Conclusion This study demonstrates in a large patient population that a deep intrinsic MCM location is not necessarily associated with an unfavorable clinical outcome after microsurgical lesionectomy. Predicting the aspect of the midbrain surface by evaluating preoperative MR images alone was not sufficiently reliable.

Intravascular papillary endothelial hyperplasia (IPEH), a rare benign endothelial vascular lesion related to thrombosis, generally develops in fingers, trunk, head, and neck. Nevertheless, it has been rarely reported in the salivary gland. In this article, we report a case of IPEH of the right submandibular gland in a 37-year-old female whose initial impression was sialadenitis secondary to sialolithiasis. To date, our case may be the first well-documented report of IPEH in the submandibular gland. The patient underwent ablation of the submandibular gland, and no evidence of recurrence was found during follow-up.

Vascular lesions of the head and neck region in children constitute an interesting group of lesions that benefit immensely from imaging techniques. Imaging is essential for identification, characterization, and delineation of the extent of lesion and subsequent follow-up. Infantile hemangiomas, which are vascular tumors with a specific evolution pattern, constitute a large majority of these lesions. On the other hand, there are vascular malformations, which are anomalies of the vascular system, consisting of a range of vascular tissues associated with various flow patterns. When diagnosis is clinically evident, imaging should utilize non-radiation techniques and address the issues necessary for management. Timing and interpretation of imaging methods employed in assessing childhood vascular lesion should also take into consideration the natural history so that imaging is performed to address a specific question. This review highlights the typical appearance of a hemangioma and a group of vascular malformations of the head and neck. For descriptive purpose, an attempt has been made to group lesions into specific subsites, with each one having specific clinical significance. Cases included illustrate the spectrum of the disease ranging from classical form in young children to slightly differing manifestations of the disease in adolescents and adults. The illustrations also provide a novel way of presenting image data using volume-rendering techniques of 3D data. Multi-modality team interaction and management strategies of these complex lesions are also emphasized.

Introduction: Imaging characteristics and prognosis on the follow-up imaging in patients with acute cervicocerebral artery dissection are not well established. Hypothesis: Initial lesion patterns on early vascular imaging would predict vascular imaging outcomes in acute cervicocerebral artery dissection. Methods: Individual clinical data and imaging features were obtained from 167 consecutive patients who presented with acute ischemic symptoms or headache due to cervicocerebral artery dissection. Patients were categorized according to their baseline vascular imaging features as either Stenosis Only, Aneurysm Only, or Both Stenosis and Aneurysm. The angiographic characteristics and improvements of early vascular lesions between baseline (within 7 days after symptoms onset) and follow-up vascular images (6-month or 1-year after symptom onset) were compared. Results: A total of 76 patients who underwent baseline and 6-month or 1-year vascular imaging were included. Patients in the Stenosis Only group (n=36) were younger (mean age, 45±11) than those in the Aneurysm Only (n=9, 55±7) and Both Stenosis and Aneurysm (n=31, 48±12) groups (p=0.044). The most common sites of lesions were the distal vertebral artery and posterior inferior cerebellar artery (n=43, 57%). All patients in Aneurysm Only group had their lesions in the posterior circulation (61% in Stenosis Only, 77% in Both Stenosis and Aneurysm; p=0.047). A total of 43 patients (57%) showed improvement of initial lesions on follow-up vascular images (58% in Stenosis Only vs. 22% in Aneurysm Only vs. 65% in Both Stenosis and Aneurysm; p=0.076). The proportion of patients who obtained improvements on follow-up vascular images on baseline images was lower in Aneurysm Only compared with groups with stenosis (Stenosis Only and Both Stenosis and Aneurysm) (Odds ratio 0.18, 95% CI 0.03 to 0.94; p=0.035). Conclusions: Complete or partial improvements on follow-up images are obtained in over half of the patients with acute cervicocerebral artery dissection. Patients with only aneurysm on early images showed poor imaging prognosis compared to patients with stenosis.

The authors describe a case when a recurrence of a true splenic cyst developed after non-radical excision of its membranes. During the second surgery, a combined surgical technique was applied for membranes destruction: diathermocoagulation, argon laser irradiation and taking a strand of the greater omentum closer to the surfaces of treated cyst membranes. Half a year later, there was no recurrence revealed at the follow-up examination. It indicates that the cyst was radically removed.

Background. Surgery has previously been the only treatment for lymphatic malformations (LMs), but in the head and neck region is challenging due to the risk of scarring, nerve damage, recurrence. Sclerotherapy may be a perfect alternative.Objective. The aim of the study is to determine the efficacy and safety of the OK-432 sclerotherapy in the children with craniofacial LMs.Methods. 81 children with head and neck LM between December 2010 and March 2017were involved into the study. The follow-up period was from 6 to 79 months. According to the size of cysts, LMs were classified into macrocystic, microcystic, and mixed. The result of the treatment of LMs was determined by the percentage of reduction in size as excellent (decrease by more than 90%), good (by 50%-89%), satisfactory (by 20%-49%) and none (by less than 20%).Results. The macrocystic LMs diagnosed in 41.97% of patients, microcystic - in 12.35%, and mixed – in 45.68% of children. OK-432 sclerotherapy only was performed for 83.9% of patients and in 12.3% in combination with surgery. The range of sclerotherapy sessions was from 1 to 11. An excellent result in 96.97% of cases was evidenced in the patients with macrocystic LM. Poor result was proved in the patients with microcystic LMs; the most of them (55.56%) had satisfactory result. In the patients with mixed LM, an excellent and good result was evidenced in 83.33%. After 198 sessions of OK-432 sclerotherapy, complications associated with the treatment occurred in 5 (2.52%) cases.Conclusions. OK-432 sclerotherapy is a safe and effective treatment of head and neck LMs in children. Macrocystic LMs proved the best response to OK-432 treatment.

Object. The effects of gamma thalamotomy for parkinsonian and other kinds of tremor were evaluated. Methods. Thirty-six thalamotomies were performed in 31 patients by using a 4-mm collimator. The maximum dose was 150 Gy in the initial six cases, which was reduced to 130 Gy thereafter. The longest follow-up period was 6 years. The target was determined on T2-weighted and proton magnetic resonance (MR) images. The point chosen was in the lateral-most part of the thalamic ventralis intermedius nucleus. This is in keeping with open thalamotomy as practiced at the authors' institution. In 15 cases, gamma thalamotomy was the first surgical procedure. In other cases, previous therapeutic or vascular lesions were visible to facilitate targeting. Two types of tissue reaction were onserved on MR imaging: a simple oval shape and a complex irregular shape. Neither of these changes affected the clinical course. In the majority of cases, the tremor subsided after a latent interval of approximately 1 year after irradiation. The earliest response was demonstrated at 3 months. In five cases the tremor remained. In four of these cases, a second radiation session was administered. One of these four patients as well as another patient with an unsatisfactory result underwent open thalamotomy with microrecording. In both cases, depth recording adjacent to the necrotic area revealed normal neuronal activity, including the rhythmic discharge of tremor. Minor coagulation was performed and resulted in immediate and complete arrest of the remaining tremor. Conclusions. Gamma thalamotomy for Parkinson's disease seems to be an alternative useful method in selected cases.
