Fulminant respiratory failure due to severe pneumothorax after re-do coronary artery bypass grafting treated with veno-venous extracorporeal membrane oxygenation.

This case report details the management of a 79-year-old man who developed massive postoperative pneumothorax following redo coronary artery bypass grafting due to severe lung adhesions. We successfully treated the patient using veno-venous extracorporeal membrane oxygenation without femoral cannulation, allowing for early rehabilitation initiation. Veno-venous extracorporeal membrane oxygenation is a reasonable option for cases of severe respiratory failure due to pneumothorax with lung destruction caused by re-sternotomy during re-do cardiac surgery.

A case of non-bacterial thrombotic endocarditis on the aortic valve following coronary angiography.

Nonbacterial thrombotic endocarditis (NBTE) on the aortic valve involves fibrin and platelet aggregate formation, potentially leading to embolic events. We present a case of NBTE on the aortic valve following coronary angiography (CAG) in a 54-year-old man with multiple comorbidities. Surgical thrombectomy was performed owing to acute cerebral infarcts. This case highlights the significance of considering that mechanical trauma from catheterization during CAG can trigger thrombus formation.

Giant Superior Mesenteric Artery Aneurysm Treated by Endovascular Treatment in a Very Elderly Female

Superior mesenteric artery (SMA) aneurysms (SMAAs) are rare and account for approximately 7% of all visceral artery aneurysms. If the anatomical complexity permits and the patency of organ perfusion is allowed, then an endovascular approach is the first choice for minimally invasive procedures. We report the case of a 92-year-old female with a giant SMAA and challenging anatomy, including a short proximal sealing zone from the origin of the SMA and a short distal sealing zone from the hepatic artery bifurcation. In view of her advanced age, she was treated endovascularly with covered stents. Reintervention was required to correct a postoperative endoleak; however, a favorable outcome was achieved with endovascular therapy.

A Giant Aortic Arch Aneurysm with Aortopulmonary Fistula / 日本心臓血管外科学会雑誌

A 69-year-old woman complained of general malaise. Chest X-ray film revealed massive left-sided pleural effusion and CT detected a giant aneurysm of the aortic arch. A diagnosis of ruptured aortic arch aneurysm was made and she underwent total arch replacement as emergency surgery. The intraoperative diagnosis was not a ruptured arch aneurysm but an arch aneurysm penetrating into the left pulmonary artery. The postoperative course was uneventful and the patient was discharged home on the 16th postoperative day.

Mitral Valve Replacement in a Patient with Severe Atrial Calcification / 日本心臓血管外科学会雑誌

<p>A 70-year-old woman, who had a history of a percutaneous transvenous mitral commissurotomy for rheumatic heart disease 34 years previously, was admitted with progressive right heart failure. Massive calcification of the left wall was observed on multidetector CT. She underwent a mitral valve replacement, tricuspid annuloplasty and permanent pacemaker implantation. Massive calcification of the left atrial wall is a rare condition, and constitutes a major complication and risk to mitral valve surgery because of the difficulty in entering the left atrium, potential embolization, and impaired hemostasis.</p>

Influence of prosthesis type on long-term survival after re-replacement of aortic valve prosthesis.

BACKGROUND: The purpose of this study is to examine the influence of the prosthesis type on early mortality and long-term survival after re-replacement of aortic valve prosthesis, especially in patients over 60 years old. METHODS: Late outcome of 223 patients who underwent a reoperation on the aortic valve and received a mechanical (mechanical group) or biological (biological group) heart valve prosthesis at a single institution were analyzed for survival and major valve-related complications, including structural valve deterioration, thromboembolism, hemorrhage, further reoperation, and valve-related mortality. RESULTS: Preoperative New York Heart Association class IV (P = 0.001), emergency procedure (P = 0.002), and endocarditis (P = 0.025) were significant risk factors for 30-day mortality rates, which were 8.4 % and 12.5 %, respectively (mechanical versus biological group, P = 0.361). A subanalysis of elective patients revealed a low risk of 30-day mortality of 2.4 % and 1.8 %, respectively. Event-free survival was comparable at 5 years (73.9% ± 3.6% versus 70.5% ± 6.5%, mechanical versus biological group) and 10 year (49.7% ± 5.0% versus 35.3% ± 9.8%, mechanical versus biological group). In a propensity-matched subanalysis, survival and event-free survival were comparable at 5 and 10 years in both groups. CONCLUSION: The type of aortic valve prosthesis did not affect early outcome and late survival in patients who underwent valve replacement, and therefore, the current strategy favoring a biological aortic valve prosthesis for patients aged over 60 years in first-time operations could also be applied in re-replacement.

Mirtazapine provided remarkable relief for refractory nausea and vomiting by sunitinib and oxycodone in a patient with renal cancer

<b>Introduction</b>: Mirtazapine is a noradrenergic and specific serotonergic antidepressant (NaSSA) and the previous reports show that may reduce nausea by inhibition of the serotonin 5-HT3receptor. <b>Case report</b>: A 38-year-old woman with advanced renal cancer with distant metastases was administered by sunitinib and oxycodone. Refractory nausea and vomiting developed during the course and mirtazapine at a daily dose of 1.875 mg was begun. The patient's nausea improved during the next day, and furthermore, by increasing the daily dose to 3.75 mg, vomiting was also improved on the third day. The therapy could be continued without withdrawal of sunitinib and oxycodone due to digestive symptoms. Although somnolence might be induced at a daily dose of 15 mg, the present low-dose mirtazapine could improve digestive symptoms without somnolence. <b>Conclusion</b>: We conclude that low-dose mirtazapine is one effective option for refractory nausea and vomiting during administration of sunitinib and oxycodone.

Local drainage for Fournier's gangrene developed in palliative care unit provided pain relief in a terminally ill patient with bladder cancer

This paper presents the case of a man in his 70's with local advanced bladder cancer with hospital-developed Fournier's gangrene. The patient was hospitalized at the palliative care unit, and drainage with incision of the scrotum for symptom relief was performed to relieve severe pain. The patient experienced pain only during changing of the wound's dressing and no pain at rest after the operation. Furthermore, he reached his birthday and spent time in peace with his family. Fournier's gangrene is the necrotizing fasciitis of perineal and anal lesions, in which inflammation progresses rapidly in wide lesions, and it is associated with a high mortality rate. For Fournier's gangrene in a terminally ill patient, current agreement might depend on the patient's goal of treatment. The drainage provided for spiritual care of the patient and his family as well as pain relief. In conclusion, local drainage for Fournier's gangrene can be feasible as a choice of palliative treatment. Palliat Care Res 2011; 6(2): 340-343

Clear Cell Sarcoma of the Kidney: A Case Report of an 11-year-old Boy and A Review of 11 Cases in Japan / Journal of Rural Medicine

An 11-year-old boy experienced right flank pain on October 12, 2005. The pain was once alleviated but recurred on the following day, and the patient visited our hospital on October 13, 2005. An imaging study revealed a tumor, sized approximately 12.0 × 7.5 × 8.0 cm, in the right kidney without metastases, for which right nephrectomy was performed. The tumor was solid, although degenerative necrosis and hemorrhage were partially observed inside the tumor. A histopathological study revealed poorly-defined, almost round tumor cells which were strongly stained with vimentin but not with cytokeratin or epithelial membrane antigen (EMA). Based on these findings, a diagnosis of clear cell sarcoma of the kidney in Stage II was made. A review of 10 previous cases reported in Japan during the past 10 years revealed that the affected patients were mostly aged 1 month to 4 years, while our case, occurring in an 11-year-old patient, was uncommon in respect to age.

A Case of Simultaneous Redo Aortic Root Replacement and Total Arch Replacement 19 Years after the Original Bentall Operation / 日本心臓血管外科学会雑誌

A 50-year-old man had undergone an initial original Bentall operation 19 years previously and replacement of the descending thoracic aorta 3 years previously. Computed tomography and an angiogram revealed a distal arch aneurysm and an ascending aortic aneurysm, neither of which had been detected 3 years previously. Detached anastomosis of the distal site and both coronary ostia were confirmed in the operation. Redo aortic root replacement and total arch replacement were performed successfully. His postoperative course was excellent.
