Mid-ventricular obstruction (MVO) rarely occurs in patients without hypertrophic cardiomyopathy. Increased cardiac contractility may play an important role in causing MVO. We experienced a case of severe chest pain and MVO in a 50-year-old female patient. She had hypertension, diabetes, stroke and peripheral artery disease. Her blood pressure was very high (222/122 mmHg) with severe fluctuation. The transthoracic echocardiography revealed MVO accompanied by hyper-dynamic left ventricular systolic function. We regarded her chest pain and MVO as secondary findings related to other diseases. Coronary angiography and several tests for uncontrolled hypertension were performed, and those evaluations revealed that she had coronary artery disease and hyperthyroidism. We considered that the increase in the myocardial oxygen demand in response to the increase in cardiac contractility and workload associated with hyperthyroidism aggravated her symptoms and MVO. She was treated with methimazole and beta blockers and her symptoms dramatically improved.

This is a report of a. case in which a long narrow segment coarctation of the aorta was successfully corrected with Teflon graft. The patient was 30 year old man with hypertensive symptoms that occurred 7 years prior to operation. Blood pressure measured 230/110 mmHg in the arms and 110/80 mmHg in the legs. Pulses were strongly tensive in radial artery, but very weak in femoral artery and even absent in dorsal pedis artery. Final preoperative diagnosis was made by aortography which showed a long narrow segment between aortic arch and descending thoracic aorta and highly developed collateral circulations. A long hypoplastic narrow segment was located proximal to the ligament arteriosus, and diaphragmatic stenosis of the aorta was located just distal to the ligamentum arteriosus. After prosthetic correction of the coarctation of the aorta, blood pressure were measured 130/ 80 mmHg in the arms and 150/100 mmHg in the legs. Peripheral pulses were palpated normally, and the postoperative course was uneventful.

Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is determined according to the progression of vascular stenosis. In our patient, SVAS and PPAS showed rapid concurrent progression within two weeks after birth. We report the early manifestation of SVAS and PPAS in the neonatal period and describe the surgical treatment for stenosis relief.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic necrotizing vasculitis that predominantly affects small vessels of the body. The two most common ANCAs are myeloperoxidase ANCA and proteinase 3 ANCA. Neurological manifestations are frequent in patients with AAV, including peripheral neuropathy, meningitis, and stroke. AAV-associated ischemic stroke usually affects small vessels supplying the white matter or brainstem. This case report details the presentation and treatment course of a 70-year-old man with rapidly progressive multiple intracranial large artery involvement attributed to myeloperoxidase ANCA-associated vasculitis. Despite treatment with high-dose steroids and a rituximab infusion, the patient developed new speech difficulties and respiratory distress, and brain imaging confirmed new stroke lesions with progressive multiple intracranial large cerebral artery involvement. The patient died from SARS-CoV-2 infection 4 months after the diagnosis. This case emphasized the rare presentation of rapidly progressive large vessel involvement in a patient with myeloperoxidase ANCA-associated vasculitis despite active immunotherapy.

Purpose: An aneurysm is defined as a permanent, localized dilation of an artery with a 50% increase in diameter over its expected normal diameter. Aneurysms can be classified by cause as traumatic and nontraumatic. Traumatic aneurysms can be divided into true and false aneurysms. Nontraumatic causes of peripheral artery aneurysms include mycotic, atherosclerotic, inflammatory, and idiopathic. In the hand, true aneurysms occurring at the common digital artery have been rarely reported. We present a rare case of a true aneurysm of the common digital artery that was resected and reconstructed using a reversed vein graft. Methods: A 49-year-old male patient was refered to our institution with a $0.73{\times}0.44{\times}1.37cm$ sized pulsating mass between 2nd and 3rd flexor digitorum tendons on Lt. palm area. The mass had been present for 5 years and had increased in size over the previous year. No history of trauma was reported. After a physical examination and ultrasound sonography review, a diagnosis of aneurismal dilatation of common digital artery was made. Surgical treatment by excision of the aneurysm, and a reversed vein graft was performed. Results: Histologic examination of the specimen ($3.4{\times}0.7cm$) showed aneurismal dilatation, with elastin fibers present in the arterial wall. The lesions were healed without any complications and there were no evidence of recurrence. Doppler examination of the reconstruction showed good perfusion. Conclusion: Early excision is recommended to relieve symptoms and avoid neurologic damage. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft. Micro surgical repair was the only possible treatment in this case. The authors believe that the vascular anatomy should always be restored as natural as possible.

Background : The ankle brachial pressure index (ABI) is a simple, useful method for diagnosing peripheral artery disease (PAD). Although the ABI is an objective diagnostic method, it has limited reliability in certain scenarios. The aim of the present study was to determine the accuracy and reliability of the toe brachial index (TBI) as a diagnostic tool for detecting stenosis in PAD, associated with normal or low ABI values. Methods : ABI and TBI values were measured in 15 patients with diabetic gangrene who were suspected of having lower extremity arterial insufficiency. The ABI and TBI values were measured using a device that allowed the simultaneous measurement of systolic blood pressure in the upper and lower extremities. In addition, the ABI and TBI values were compared pre- and post-angiography. Results : Patients with an ABI of 0.9-1.3 showed almost no difference between the 2 measurements. The patients with TBI >0.6 had no arterial insufficiency. The patients with TBI <0.6 required vascular intervention with ballooning. After the angiography, the gangrenous wounds decreased in size more rapidly than they did prior to the intervention. Conclusions : Our findings suggest that TBI is the method of choice for evaluating lower limb perfusion disorders. This result requires further studies of TBI in a larger number of patients. Future long-term studies should therefore evaluate the utility of TBI as a means of screening for PAD and the present findings should be regarded as preliminary outcomes.

Atherectomy has become a promising treatment option for peripheral artery disease caused by diabetes mellitus or end-stage renal disease. Atherectomy refers to the removal of atheromatous tissue by mechanical method, resulting in an enlarged lumen of the treated blood vessel. Based on this method, the term is limited to the percutaneous minimally invasive approach, and there are currently two types of atherectomy devices available in Korea. The increased prevalence of atherectomy has led to the concept of "vascular preparation" and a new treatment concept of "leave nothing behind." Various studies have proven the safety and effectiveness of atherectomy; however, there are some limitations. We need to remain focused on patient selection and subsequent large-scale research.

There is tendency of increasing number and decreasing age of patients who are indicated for Rastelli operation for their cyanotic congenital heart disease. So there is the need to find the criterion which saves the patients from early postoperative hemodynamic disturbances. We reviewed the 26 patients who had been performed Rastelli operation at Seoul national University Hospital from January 1981 to June 1988. mean age of the patients was 7.8*3.4 years[range 2.5-15years], mean body surface area[BSA] 0.79*0.25m2[range 0.49-1.51m2] and mean hematocrit 57.95*12%[range 48-80%]. We divided these patients into survived group and died group before postoperative 72 hours, and analyzed preoperative arterial oxygen saturation[SaO2], the ratio of diameter of right pulmonary artery to ascending aorta[RPA/AA], the ratio of both right and left pulmonary artery diameter to descending thoracic aorta[RPA+LPA/DTA], pulmonary artery index[PA index], cardiopulmonary bypass time, aorta cross-clamping time, postoperative perfusion state and total amount of dopamine infused postoperatively. The results showed that RPA+LPA/DTA and PA index were statistically significant factors to influence early postoperative cardiac death rate[P< 0.05]. Especially there were good linear correlations between PA index[X] and peripheral perfusion index[Y][Y= - 1.15+0.02 X, r=0.86, P<0.01]and between PA index[X] and total amount of dopamine infused before postoperative 72 hours[mg/kg, Y][Y=61.94 - 0.15 X, r=-0.80, P < 0.01]. Also there were tendencies that the higher RPA+LPA/DTA[Y], the better peripheral perfusion [X] and the lower need of dopamine[X], but no statistical significance.[Y=0.78+1.60 X, r =0. 49, P >0.05] And the discriminate analysis showed that patients with PA index over 221 mm2/BSA could undergo correction with 25 per cent of error rate. In conclusion, early postoperative hemodynamic states could be predicted by preoperatively measured PA index, and which can be used as a criterion for Rastelli operation performed on cyanotic congenital heart disease.

Popliteal artery entrapment syndrome (PAES) is a non-artherosclerotic cause of claudication and acute ischemia of the legs in young athletic individuals. It is classified in terms of the abnormal anatomical relationship between the popliteal artery and surrounding structures. All types of PAES have the same pathophysiology. Repetitive arterial compression by surrounding structures causes progressive vascular injury. Bilateral PAES is reported in about 30% of cases. Bilateral PAES is usually of the same type in each artery; exceptions are rare. We report a case of a young athletic patient who suffered bilateral PAES of two different types.

Purpose: The clinical syndrome of unilateral finger ischemia, caused by digital artery occlusions from embolization from the palmar ulnar artery associated with repetitive striking of the palm, has been called the hypothenar hammer syndrome (HHS). We report the case of a man with this unique disease probably caused by manual work. Methods: A 52 - year - old male left - hand dominant manual worker complained of pain and coldness in the left 4,5th finger. On physical examination, there was a tip necrosis and the result of Allen's test was mildly positive(sluggish filling of hand from the ulnar artery). Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch and distal digital artery. Surgical bypass with reverse autologous vein grafting was performed between ulnar artery and superficial palmar arch, common digital artery. Results: He had an uneventful postoperative course and has remained asymptomatic for 18 months since discharge. Patency has been confirmed by color doppler with resolution of cold intolerance and successful digital preservation. Conclusion: We introduce very unique pattern of vascular ischemic disease and recommend the arterial bypass with vein interpositional grafting.
