    Myocardial bridge (MB) is a chance anatomical structure, comprised of the myocardial tissue, with which the coronary artery running in epicardial adipose tissue is partly covered. It is predominantly present in the left anterior descending artery (LAD) and recognizable through imaging techniques as changes in blood flow within the LAD that arises from MB contraction at cardiac systole. Such changes in blood flow influence the pathophysiology of coronary circulation and atherosclerosis development, thus generating controversy as to whether MB predisposes individual to myocardial infarction (MI). However, recent histomorphometric studies have shown that the individual anatomic properties of MB, such as location, length and thickness, consistently play a critical role in the occurrence of MI. This review article comprehensively addresses the pathophysiological mechanisms of MI occurrence together with the benign suppressive effect of coronary atherosclerosis by MB.

    Endothelial dysfunction and autonomic nervous system dysfunction are both risk factors for atherosclerosis. There is evidence demonstrating that there is a close interrelationship between these two systems. In hypertension, endothelial dysfunction affects the pathologic process through autonomic nervous pathways, and the pathophysiological process of autonomic neuropathy in diabetes mellitus is closely related with vascular function. However, detailed mechanisms of this interrelationship have not been clearly explained. In this review, we summarize findings concerning the interrelationship between vascular function and the autonomic nervous system from both experimental and clinical studies. The clarification of this interrelationship may provide more comprehensive risk stratification and a new effective therapeutic strategy against atherosclerosis.

    Objective: The purpose of this study was to review patients who underwent inferior vena cava (IVC) resection with concomitant malignant tumor resection and to consider the operative procedures and the outcomes.Materials and Methods: Between 2000 and 2012, 41 patients underwent resection of malignant tumors concomitant with surgical resection of the IVC at our institute. The records of these patients were retrospectively reviewed.Results: Primary tumor resections included nephrectomy, hepatectomy, retroperitoneal tumor extirpation, lymph node dissection, and pancreaticoduodenectomy. The IVC interventions were partial resection in 23 patients and total resection in 18 patients. Four patients underwent IVC replacement. Operation-related complications included pulmonary embolism, acute myocardial infarction, deep vein thrombosis, leg edema and temporary hemodialysis. There were no operative deaths. The mean follow-up period was 24.9 months (range: 2–98 months). The prognosis depended on the type and stage of the tumor.Conclusion: Resection and reconstruction of the IVC can be performed safely if the preoperative evaluations and surgical procedures are performed properly. The IVC resection without reconstruction was permissive if the IVC was completely obstructed preoperatively, but it may also be considered in cases where the IVC is not completely obstructed.

    Objective: To investigate the ability of source image of time-of-flight magnetic resonance angiography (TOF-MRA) in the detection of fibrous cap rupture of atherosclerotic carotid plaques.Materials and Methods: From the database of radiological information in our hospital, 35 patients who underwent carotid MR imaging and subsequent carotid endoarterectomy within 2 weeks were included in this retrospective study. MR imaging included thin-slice time-of-flight MR angiography, black-blood T1- and T2-weighted imaging. Sensitivity, specificity and accuracy were calculated for the detection of fibrous cap rupture with source image of TOF-MRA. The Cohen k coefficient was also calculated to quantify the degree of concordance of source image of TOF-MRA with histopathological data.Results: Sensitivity, specificity and accuracy in the detection of fibrous cap rupture were 90% (95%CI: 81–98), 69% (95%CI: 56–82) and 79% (95%CI: 71–87) with a k value of 0.59. The false positives (n = 15) were caused by partial-volume averaging between fibrous cap and lumen at the shoulder of carotid plaque. The false negatives (n = 5) were underestimated as partial thinning of fibrous cap.Conclusion: Source image of TOF-MRA can be useful in the detection of fibrous cap rupture with high sensitivity, but further technical improvement should be necessary to overcome shortcomings causing image degradation.

    Objective: To investigate the safety and efficacy of a novel arm sleeve composed of a conventional arm sleeve extending to a wider area of the body.Materials and Methods: Five subjects with post-mastectomy upper extremity lymphedema, who had already been using their own arm sleeve, used a brand-new conventional arm sleeve for 2 weeks, followed by a novel arm sleeve for 2 weeks. The adverse events, arm-related symptoms, interface pressures, and subcutaneous fluid distributions observed by magnetic resonance imaging (MRI) were assessed.Results: The use of the novel arm sleeve resulted in a graduated compression extending to the shoulder (forearm, 21.8 ± 3.7 mmHg; upper arm, 15.2 ± 3.3 mmHg; shoulder, 8.8 ± 3.1 mmHg). By eliminating the wring seen in the conventional arm sleeve, the disturbed proximal diffusion of the subcutaneous fluid and venous occlusion were successfully avoided, as confirmed by MRI. No adverse event or worsening of arm-related symptoms was reported.Conclusion: The novel arm sleeve seemed to provide graduated compression to a wider area, allowing improved subcutaneous fluid and venous drainage without any adverse events. Therefore, the novel arm sleeve may be recommended as a compression therapy option for upper extremity lymphedema.

    We present a case in which a single stage hybrid repair was successfully for a complicated acute type B dissection of the aortic arch involvement in a 63-year-old male patient. We performed a combination of different techniques; left subclavian artery debranching, elephant trunk insertion without aortic arch replacement, and thoracic endovascular aortic repair (TEVAR) from antegrade approach. The postoperative course was successful, and the patient was discharged on day 11 after surgery. A-half-year’s follow up computed tomography (CT) scan showed shrinkage of thrombus lumen, vascular reverse remodeling.

    Aortoiliac arterial steno-occlusions in young or middle-aged patients are relatively rare and have been reported in the literature as small aorta syndrome (SAS) or hypoplastic aortoiliac syndrome. We report the case of a 48-year-old Japanese woman with intermittent claudication caused by SAS. We performed left iliofemoral bypass grafting with a Dacron graft via a retroperitoneal approach. Bypass grafts, endarterectomy, and sympathectomy have been used for surgical management. Given that post-procedural event rates are higher for SAS than for other common atherosclerotic diseases, patients with SAS should be closely followed up after surgery.

    Mondor’s disease is characterized by thrombophlebitis of the superficial veins of the breast and the chest wall. The list of causes is long. Various types of clothing, mainly tight bras and girdles, have been postulated as causes. We report a case of a 34-year-old woman who referred typical symptoms and signs of Mondor’s disease, without other possible risk factors, and showed the cutaneous findings of the tight bra. Therefore, after distinguishing benign causes of Mondor’s disease from hidden malignant causes, the clinicians should consider this clinical entity.

    An 86-year-old man with a 75-mm TAA that terminated just above the celiac artery was treated with a customized Zenith stent graft that had a distal fenestration for the superior mesenteric artery (SMA). Because angiography demonstrated a type IB endoleak, an additional extension stent graft was deployed, and coil embolization of the aneurysmal sac was performed. Three months later, there was no endoleak and good visceral blood flow. Placement of a fenestrated thoracic stent graft with a scallop-like fenestration for the SMA is a promising procedure for the treatment of TAAs with a short distal neck.

    Late upper extremity embolic complications of occluded axillofemoral bypass graft (AxFG) or occluded axillo-axillary bypass graft (AxAG) are not frequently noted. A patient presented with acute right upper extremity thromboembolism 2 years after an AxFG occlusion. Computed tomography (CT) findings revealed kinking and occlusion of the axillary artery at the anastomosis. Another patient presented with acute left upper extremity thromboembolism 2 years and 6 years after an AxAG occlusion. CT indicated a thrombus progressing from the occluded graft to the axillary artery. Surgical repair of the axillary artery was performed in both patients without any complications.

    A 66-year-old man was referred for treatment of critical limb ischemia arising with multiple organ dysfunction due to acute pneumonia. Angiographic examinations demonstrated total obstruction of the bilateral external iliac arteries and the bilateral superficial femoral arteries with collateral circulation to the distal vessels. Urgent percutaneous transluminal angioplasty dissolved the obstruction of the left external iliac artery, and subsequent low-density-lipoprotein apheresis ameliorated his progressive ischemia in the lower extremities. Femoro-femoral and bilateral femoro-popliteal bypasses were performed 31 days after the endovascular intervention, which achieved successful limb salvage with the relief of ischemic symptoms related to arteriosclerotic obliterans.

    Blunt traumatic injury to the innominate artery is relatively rare. We present the case of a 40-year-old woman who fell from a fourth-floor window and was transferred to our hospital with multiple injuries, hemodynamic shock, and disturbance of consciousness. Computed tomography with image reconstruction revealed transection of the innominate artery near its origin. Emergent surgery required establishment of cardiopulmonary bypass before sternotomy in preparation for uncontrollable hemorrhage. Proximal aortic arch replacement with a branch to the right axillary artery was successfully performed using circulatory arrest and selective cerebral perfusion.

    Recently, we experienced a rare case of Budd-Chiari Syndrome. The case was a 57-year-old female patient. Venous return had been severely disturbed by the membranous occlusion of the IVC and a giant floating thrombus. After catheter directed thrombolysis combined with stepwise percutaneous angioplasty, the IVC was recanalized sufficiently and the thrombus was completely resolved.

    We report the case of a 37-year-old man with isolated unilateral absence of the pulmonary artery (UAPA), which was diagnosed upon the occurrence of hemoptysis. Plain chest radiography demonstrated decreased left pulmonary volume. Computed tomography of the chest revealed the complete absence of the left pulmonary artery. Angiography revealed marked dilation of the left bronchial artery, inferior phrenic artery, internal thoracic artery, and the arterial branches of the thyrocervical trunk. These arteries were considered as collateral circulation to the left lung. In cases with UAPA, collateral circulation should be evaluated by angiography to obtain useful information for treatment.

    A 72-year-old woman who had aortic arch aneurysm was admitted. The patient was unable to walk without assistance because of aortoiliac occlusive disease. Total arch replacement and the ascending aorta to the bilateral profunda femoris artery bypass were performed during the same operation. On outpatient visits, the patient was able to walk with a cane and the ankle-brachial pressure index was markedly improved. This combined procedure is an option for patients with aortoiliac occlusive disease who are not candidates for alternate inflow procedures, especially when the patient has another indication for median sternotomy.

    We report the anatomical similarity of abdominal aortic aneurysms (AAAs) regarding morphology and visceral vessel relations with three-dimensional computed tomography in monozygotic twins, both of whom had the left accessory renal artery, patent inferior mesenteric artery and bilateral common iliac artery aneurysms without aortic wall calcification and mural thrombus in the same fashion. Both twins underwent AAA open repair for enlargement of it at the same age. Genetic contributions might be strongly associated with morphology and visceral vessel relations of AAAs in monozygotic twins.

    A 65-year-old man infected with human immunodeficiency virus underwent emergency surgery for rupture of a mycotic descending thoracic aneurysm. The aneurysm was replaced with a prosthetic graft wrapped with omentum. Esophageal perforation occurred 3 weeks after surgery. The patient’s condition remained stable, and we adopted a conservative treatment. The esophageal fistula had not healed completely and a biopsy of the scar revealed gastric cancer. We performed a distal gastrectomy, Roux-Y reconstruction, and enterostomy for enteral feeding. Follow-up endoscopy revealed healing of the fistula, and the patient was eventually discharged. We managed this potentially fatal complication with minimally invasive treatment.

    We performed divided saphenectomy (DS) for varicose vein in ambulatory surgery with minimal incisions. Under tumescent local anesthesia, this procedure ligates all perforators in the thigh, preserving a route of venous drainage, and reduces bruising by ligating all tributaries. Also, DS does not need any special surgical instrument. Subcutaneous inguinal hemorrhage was observed in 4.9% (3/61), mild bruises were observed in 19.7% (12/61), and saphenous nerve neuralgia was 1.6% (1/61). Wound infection, deep venous thrombosis, and edema were not observed. DS is a minimally invasive, simple, and cost-effective procedure.
