in general rapid and complete resolution of pulmonary emboli, even massive, is the natural history. However, rarely, the emboli do not resolve but rather became fibrotic organization and densely adherent to the arterial wall, therefore, may lead to significant clinical disability. In patients with chronic pulmonary embolism, medical management usually has little effect and only surgical treatment can offer improvement. The case was 30-year-old man who had admission to the Hanyang University Hospital due to fall-down from 11th floor 407 days before operation and then transferred to our department for surgical management under the diagnosis of chronic pulmonary embolism, Pulmonary angiogram demonstrated multifocal thromboembolism with infarction and lung scans showed no improvement in spite of anticoagulant and thrombolytic therapy. At median sternotomy for pulmonary artery thromboembolectomy, the well organized and multiple septic emboli could be removed by gallstone forceps. But reoperation of left upper lobectomy was performed because of the repeated hemoptysis and suspicious pulmonary arterio-bronchial fistula 19 days postoperatively. Despite of ventilatory support and drug treatment, the patient died due to right heart failure associated with cor pulmonale 27 days after first operation. Discussion of the operative and perioperative problems are offered.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

This report explains the intervessel pit dimension of Populus tomentiglandulosa and its role in embolism repair according to proposed mechanism by Zwieniecki and Holbrook, 2000. It was found that mean contact angle ( ) of water droplets on the inner surface of vessels was $56^{\circ}$. Openings into the bordered pits were typically elliptical. The angle of the bordered pit chamber ($2{\alpha}$) was found $142.17^{\circ}$. From the capillary equation $Pmax\;=\;Gcos\;(\;+{\alpha})$, it was found that mathematically the maximum pressure 0.08MPa created by pits, can be employed to force the air within the embolized vessel into solution.

Unresolved major pulmonary embolism (UMPE) is an uncommon condition which causes pulmonary hypertension, cor pulmonale and death. An accurate and prompt diagnosis of UMPE is very important in the management of such patients with pulmonary embolectomy. Follow-up lung scans can lead to earlier diagnosis of UMPE especially on patients who have a history of acute pulmonary embolism in the past and. present with pulmonary hypertension, respiratory insufficiency and cor pulmonale. We report a case of UMPE strongly suggested by follow-up lung scans and subsequently confirmed by pulmonary angiography and postmortem examination.

Pulmonary embolism (PE) is a serious complication that can occur after orthopedic surgery. Most instances of PE in the orthopedic field have occurred after hip or knee arthroplasties or after fracture surgeries. The occurrence of PE related to arthroscopic shoulder surgery is very rare. We report a case of PE that developed after arthroscopic rotator cuff repair, in which the patient did not show preoperatively any remarkable risk factors for PE. We also review the current literature related to this topic.

Fat embolism syndrome (FES) is a clinical manifestation that consists of multiple organ dysfunction due to fat emboli. FES occurs as a complication after trauma or procedures such as surgery. The diagnostic criteria of FES have not yet been established, so clinical criteria are used for its diagnosis. The clinical course of acute fulminant FES can be rapid. Liposuction surgery, in which adipocytes are mechanically disrupted, is one cause of FES. As the number of liposuction surgeries increases, clinicians should be aware of the possibility of FES. This was the first report of a case of acute fulminant FES with severe acute respiratory distress syndrome after liposuction surgery, in Korea.

Hyaluronic acid is widely used in medical procedures, particularly in cosmetic procedures administered by physicians or nonmedical personnel. The materials used for cosmetic procedures by physicians as well as illegally by non-medical personnel can cause nonthrombotic pulmonary embolism (NTPE). We report the case of a woman with acute respiratory failure, neurologic symptoms and petechiae after an illegal procedure of hyaluronic acid dermal filler performed by an unlicensed medical practitioner 3 days before symptom onset. Although a few cases of NTPE after injection of hyaluronic acid have been reported yet, this is the first typical case showing a NTPE manifestation after the facial injection of hyaluronic acid.

Background: The underlying pathogenesis of fat embolism-induced acute lung injury (ALI) has not been elucidated. In the present study, the pathogenesis of fat embolism-induced ALI was probed in association with neutrophilic oxidative stress in oleic acid (OA)-induced ALI of S-D rats. Methods: OA was injected intravenously to provoke ALI in experimental rats. Five hours later, indices of ALI were measured to confirm the role of the neutrophilic respiratory burst. The effect of an inhibition of phospholipase A2 (PLA2) was also evaluated. Results: The accumulation of neutrophils in the lung due to OA caused increased neutrophilic oxidative stress in lung, which was ameliorated by mepacrine. What were the results from inhibition of PLA2. Conclusion: Excess neutrophilic oxidative stress contributes to OA-induced ALI, which is lessened by the inhibition of PLA2.

The objective of this article is to describe intraoperative pulmonary embolism during shoulder arthroscopy in a patient with previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Further, we describe how the pandemic has influenced the population by increasing the rate of embolisms. Awareness of such cases will help to increase knowledge regarding SARS-Cov-2 and to determine if such patients should receive routine antithrombotic prophylaxis.

Pulmonary Embolism can develop in variable conditions, and presents with nonspecific symptoms and signs. If diagnosis is delayed, it can be resulted in catastrophic results. Therefore, early diagnosis and adequate treatment is crucial in Pulmonary Embolism. Lung Perfusion Scan is useful screening test. Negative result can exclude pulmonary embolism. But, perfusion defects don't always mean pulmonary embolism. To find the better methods of interpretation of lung perfusion scan and To evaluate the clinical course and outcomes of the patients, in whom pulmonary embolism was suspected by lung perfusion scan, we reviewed the clinical records of 49 cases suspected by lung perfusion scan at Seoul National University Hospital during the period of January, 1995 to July, 1996. The results are as follows. First impression of cases in which PE was present at time of admission were pulmonary embolism (63%), heart diseases (26%), and pneumonia (11%) in orders. Underlying diseases of cases in which PE developed during admission were malignancy (36.5%), ICH (22.7%), sepsis (13.7%), and SLE (9.1%) in orders. The predisposing factors were operation (20%), cancer (16%), immobility (16%), connective tissue disease (16%), heart dis. (10%), old age (10%), and preg/pelvic dis. (8%) The results, of lung perfusion scan were HPPE 40 cases(26.8 %), IPPE 21 cases(14.1%), LPPE 88 cases (59.1%), and cases(%) of treatment in these cases were HPPE 34 cases(85%), IPPE 9 cases(42.9%), LPPE 0 case(0.0%). Treatments were heparin and warfarin (69.5%), heparin alone (8.2%), warfarin alone (2.0%), embolectomy (4.1%), thrombolytics (2.0%), IVC filter (2.0%), and no treatment (12.2%) In 34 cases (69.4%), follow up could be done, and 5 cases were recurred (10.2%). The causes of recurrence was incomplete anticoagulant therapy (3 cases) and recurrence of predisposing factor (2 cases). Expired case due to pulmonary embolism was one who was expired just before trial of thrombolytic therapy. Conclusion : Efforts should be made to shorten the interval from onset of Sx to Dx, ie, high index of suspision.
