Despite several studies focusing on the facial arteries variable courses, the findings have significantly differed. The divergent findings have made it increasingly challenging to establish consistent correlations. Thus, as a vital artery, the facial artery is prone to numerous variations, which makes the identification of the variations vital to clinical practice, particularly for the orofacial and rhinoplastic surgery, and the increasingly selective chemotherapy procedures. The present research uses angiography images for analysis in studying the bilateral facial artery variations noted in patients undergoing carotid angiography for the evaluation of congenital anomalies, cerebral vascular malformations, and intra-arterial procedures. Conventional angiography was used, as it is a vital assessment tool that helps in the assessment of variations in the facial arteries and is suitable in evaluating smaller vascular anatomy, due to the perfect spatial resolution and portrayal of vascular anatomy. Thus, rather than normal ending of the facial artery as an angular artery, the study disclosed that in certain instances, the artery termination took the form of a superior labial artery with a small lateral nasal artery branch located closer to the midline compared to the normal cases. Also, the study has disclosed a conspicuous pre-masseteric branch with small branches originating from the infraorbital artery and providing potential compensation for the facial artery's shortness. Regardless of the infrequency of such variations, it is vital that they are considered during the performance of any facial surgical procedure.

Purpose: The Hybrid care environment, combining interventional procedures and surgeries in one space, is crucial for managing complex diseases, responding to emergencies, and reducing recovery times and pain. This study provides foundational data for creating architectural guidelines for a Hybrid Operating Unit in a general hospital's surgical department, focusing on cardiovascular care. Methods: The study analyzed the spatial and configuration types of the Vascular Angiography Unit and the Cardiac Operating Unit, which are the basic components of the Hybrid Operating Unit, through a literature review. Based on the initial research findings, interviews with experts were conducted. Results: In the Hybrid Operating Process, the study proposed spatial configuration alternatives that consider the positioning of medical staff and the types and arrangement changes of equipment, including Angiography, Heart-lung machines, and other surgical tools and instruments. Implications: The integration of the two units leads to increased diversity and demand for medical staff, equipment, and supplies during surgical and interventional procedures. Therefore, strategic spatial configurations and equipment placement are necessary to effectively respond to these needs.

In the field of oral-maxillofacial surgery, vascular malformations present in various forms. Abnormalities in the size of the tongue by vascular malformations can cause mandibular prognathism and skeletal deformity. The risk in surgical treatment for patients with vascular malformation is high, due to bleeding from vascular lesions. We report a rare case of macroglossia that was treated by partial glossectomy, resulting in an improvement in the swallowing and mastication functions in the patient. A 25-year-old male patient with severe open-bite and mandibular prognathism presented to our department for the management of macroglossia. The patient had a difficulty in food intake because of the large tongue. Orthognathic surgery was not indicated because the patient had severe jaw bone destruction and alveolar bone resorption. Therefore, the patient underwent partial glossectomy under general anesthesia. There was severe hemorrhaging during the surgery, but the bleeding was controlled by local procedures.

From 1976 through 1986, authors have experienced 127 cases of peripheral vascular surgery which had been done in this department. There were 29 cases of atherosclerosis obliterances including 7 Leriche syndrome, 32 Buerger`s diseases, 25 arterial thromboembolisms, 21 vascular injuries, 2 peripheral arterial aneurysms, 2 renovascular hypertensions, 1 congenital A-V malformation, 13 varicose vein of lower extremities, and 2 Jugular venous ectasia. Cases with vena caval disease and aortic disease were excluded. The mean age of ASO and Buerger`s disease was 56.1 yrs, 33.8 yrs respectively. The male to female ratio showed marked male preponderance [27:2, and 30:2], and almost every male patient was smoker. The indication of operation was similar in both disease entities. The method of operation for ASO were bypass procedure [17], thromboendarterectomy [6], and lumbar sympathectomy [5], and for Buerger`s disease were mainly sympathectomy and few bypass procedures and amputations. Seventeen patients with ASO were followed from 3 to 75 month and overall patency rate for bypass or endarterectomy in one and two months and 2 1/2 yr were 93%, 87%, and 31% respectively. Post operatively patient`s symptoms was relieved or alleviated in almost ASO patients, and about 60% of Buerger`s disease. We concluded that in patient with ischemic limb, we must revascularized aggressively for symptomatic relief. And choice of graft for bypass procedure was to be evaluated further.

Chronic subdural hematomas mainly occur amongst elderly people and usually develop after minor head injuries. In younger patients, subdural collections may be related to hypertension, coagulopathies, vascular abnormalities, and substance abuse. Different techniques can be used for the surgical treatment of symptomatic chronic subdural hematomas : single or double burr-hole evacuation, with or without subdural drainage, twist-drill craniostomies and classical craniotomies. Failure of the brain to re-expand, pneumocephalus, incomplete evacuation, and recurrence of the fluid collection are common complications following these procedures. Acute subdural hematomas may also occur. Rarely reported hemorrhagic complications include subarachnoid, intracerebral, intraventricular, and remote cerebellar hemorrhages. The causes of such uncommon complications are difficult to explain and remain poorly understood. Overdrainage and intracranial hypotension, rapid brain decompression and shift of the intracranial contents, cerebrospinal fluid loss, vascular dysregulation and impairment of venous outflow are the main mechanisms discussed in the literature. In this article we report three cases of different post-operative intracranial bleeding and review the related literature.

Hemangioma is a benign vascular tumor that grows by endothelial cell hyperplasia. It occurs most frequently in the head and neck region. Nose reconstruction is tricky because of its unique three-dimensional structure and different tissue components. We report a case of successful reconstruction of near-total nose defect using the paramedian forehead flap combined with a nasolabial flap, immediately after excision of nasal hemangioma. A 49-year-old male patient was presented with a huge mass at the nose. Preoperative magnetic resonance imaging showed prominent vascular channels extending to the forehead and cheek. Complete resection of the mass was performed, which resulted in an eccentric defect. The right paramedian forehead flap and the left nasolabial flap were designed and transferred to the defect. Flap division was performed 1 month later. The patient is satisfied with the overall appearance and did not develop any functional deficit.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries [abbreviated as PA+VSD+MAPCA in the following] has limited the success of attempts at accurate diagnosis and complete surgical repair. From April 1986 to September 1990, 23 patients with PA+VSD+MAPCA among 96 patients of PA+VSD in Seoul National University Children’s Hospital were encountered. The group comprised 14 male and 9 female patients with ages ranging from 17 days to 177 months [mean 49.6 months]. We operated one stage total repair on good pulmonary artery sized two patients by R.E.V. [Reparation a l’etage ventriculaire] and Rastelli operation respectively. And the 11 patients who had independent MAPCAs and hypoplastic central pulmonary artery were dealt with unifocalization and modified Blalock-Taussig Shunt and followed by second stage repair in 3 patients later. We successfully had managed 7 patients whose MAPCAs could be ligated with modified Blalock-Taussig Shunt and followed by second stage repair in 3 patients with R.E.V or Rastelli operation. Recently, three obstruction after 11 unifocalization procedures made us to try palliative right ventricle-pulmonary artery conduit operation by Gore-Tex vascular graft interposition under cardiopulmonary bypass. And so we managed another 3 patients with these procedures for the purpose of pulmonary artery growth whose central pulmonary artery were severely hypoplastic. We experienced one death after second stage repair whose central pulmonary artery was created by 12mm Gore-Tex vascular graft and was unifocalized.

The aneurysmal dilatation of ascending aorta with the aortic regurgitation presents typical surgical problems. Over the years, various surgical procedures had been used for the management of the dilated segment of sending aorta and the aortic regurgitation. The surgical technique Is still in the state of evolution. The one method is the super coronary replacement of the ascending aorta with vascular graft and replacement of the aortic valve with preservation of the coronary ostia as advocated by Miller and his colleague at Stanford University, so called conventional technique". The other is the replacement of aortic valve and the dilated segment of the ascending aorta using a composite graft and transplantation of the coronary ostia as described by Bentall and DeBono in 1968. The controversy appears to evolve around 3 technical problems. One is bleeding from the grafted area. Two is later development of the aneurysmal dilatation of the subcoronary aortic wall when non-composite graft is employed. Three is a management of the coronary arteries. The purpose of this article is to present our experience with 7 cases of annuloaortic ectasia in whom both of these surgical techniques at that employed and to review some of the problems that encountered during the management of these patients .

The authors have performed operations on vascular system of 108 cases from 1972 through 1979, and analyzed the diseases, surgical procedures and results. They were 1. Arterial system; 45 cases P.D.A. : 20 Occlusive diseases : 13 Coarctation of aorta : 4 Aneurysm : 4 A-V fistula : 2 Trauma : 2 2. Venous system; 6 cases Esophageal varix : 4 S.V.C. syndrome : 1 Varicose vein : 1 3. Arteriovenous shunt for hemodialysis; 57 cases Of the arterial diseases, the worst results came from Burger`s disease. For the bleeding esophageal varices, we have performed ligations of varices or collateral circulations rather than emergency splenorenal shunt with good results. External A-V shunt for hemodialysis had much more complications than the A-V fistula.
