Abstract

Acute occlusion of the digital arteries frequently causes painful infarction requiring digital amputation. We describe a 55-year-old male patient who presented with acute onset of digital ischemia with impending gangrene on the right hand. Because angiography revealed bypass surgery was not feasible, he underwent thoracoscopic sympathectomy (TS) one week after onset of the symptom, which resulted in rapid pain resolution. He was diagnosed, thereafter, with malignant rheumatoid arthritis and methotrexate was administered. Postoperative angiography revealed that the occluded digital artery had become recanalized. Timely TS is therefore a treatment of choice for acute digital ischemia.

90. A Case of Spontaneously Developed Retroperitoneal Parasitic Leiomyoma.

Author

Abstract

Spontaneous retroperitoneal parasitic leiomyomas are extremely rare and are mostly located in the pelvic cavity. Herein, we present a case of a small primary parasitic leiomyoma arising in the retroperitoneum. A 46-year-old Japanese woman presented with iron deficiency anemia. The patient had not undergone any abdominal surgeries. Transvaginal ultrasonography and MRI revealed multiple uterine myomas and an 18-mm, low-intensity mass adjacent to the uterus. The patient underwent a total laparoscopic hysterectomy. A solitary retroperitoneal tumor in the pouch of Douglas was resected. Histologic examination of the resected retroperitoneal tumor revealed a well-circumscribed benign leiomyoma. In this case, we suggest that retroperitoneal primary parasitic leiomyoma may have arisen independently of uterine leiomyoma. Further investigations of similar cases may fully elucidate the pathogenesis of primary retroperitoneal parasitic leiomyomas., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

91. Revision Surgery for Venous Graft Stenosis of SMA Bypass.

Author

Abstract

A 67-year-old male with postprandial abdominal pain for 4 months obtained medical attention for severe pain. He was diagnosed with small intestinal necrosis, secondary to chronic mesenteric ischemia by CT scan. We performed the surgery including a partial resection of the small intestine and left external iliac artery to the superior mesenteric artery bypass using saphenous vein graft. His symptoms improved after surgery. However, 5 months later, abdominal pain appeared after eating. A CT scan identified graft stenosis, leading to a revascularization. A synthetic vessel was used to perform the re-bypass surgery. Postoperatively, the patient's abdominal pain improved., (@ 2024 The Editorial Committee of Annals of Vascular Diseases.)

Abstract

Standard full median sternotomy for total aortic arch replacement in patients with tracheostomy has higher risks for mediastinitis and graft infection. To avoid surgical site infection, it is necessary to keep a sufficient distance between the tracheostomy and the site of surgical skin incision. We herein report a case of a 74-year-old man with permanent tracheostomy after total laryngectomy, who underwent total aortic arch replacement for an aneurysm. Antero-lateral thoracotomy in the 2nd intercostal space with lower partial sternotomy( ALPS approach) provided an enough distance between the tracheostomy and the surgical field. It also provided a good view for surgical procedure and enabled the standard setup of cardiopulmonary bypass with ascending aortic cannulation, venous drainage from the right atrium and the left ventricular venting through the upper right pulmonary vein. The operation was completed in 345 minutes and the patient was discharged on the 11th postoperative day without any complications.

Abstract

A 71-year-old woman presented with heart failure due to aortic and mitral valve regurgitation. She had developed midiastinitis and graft infection, 15 months before, following replacement of the ascending aorta for acute aortic dissection. Omentum flap operation had been performed and the infection had been controlled. This time, she underwent re-thoracotomy, and replacement of ascending aorta, aortic valve replacement and mitral valve plasty were performed. The omenal tissue was exfoliated without any damage to the heart or the great vessels by using an ultrasonic scalpel. As the omental tissue was viable, it was placed back in the mediastinal space.

Abstract

Aortic arch replacement has been safely performed by moderate hypothermic circulatory arrest, and antegrade selective cerebral perfusion. To prevent permanent neurological deficit, it is important to precisely evaluate brain, neck vessels and atherosclerotic thoracic aorta by computed tomography(CT), magnetic resonance imaging (MRI)and intraoperative epiaortic echography, which can lead the safest cannulation site, careful manipulation of cerebral perfusion catheters. It is also important to make good exposure of surgical site, especially in distal anastomosis, and irrigate and flush atheromatous debris. Since 1991 to 2013, our consecutive 410 cases of total and hemi arch replacement of aorta, including 57 emergency cases, result in 22 cases( 5.4%) of mortality( 3.1% of elective, 19.3% of emergency) and 10 cases( 2.4%) of stroke( 2.3% of elective, 3.5% of emergency). Mortality and morbidities are more likely be occurred in emergency cases. It is possible to keep good operative results with reliable brain protection of selective antegrade cerebral perfusion which gives enough time for secure open distal anastomosis to every surgeon, but atheroemborism from shaggy aorta remains as a problem yet to be solved.

Abstract

Objective: To evaluate the involvement of transforming growth factor (TGF)-beta isoforms (TGF-beta1, TGF-beta2, and TGF-beta3) on endometrial tissue remodeling during the perimenstrual period., Design: The effects of TGF-beta isoforms on the cell proliferation, motility, and contractivity of cultured human endometrial stromal cells (ESCs) were investigated., Setting: Research laboratory at a medical school., Patient(s): Nine endometrial specimens in the late secretory phase were used., Intervention(s): Endometrial stromal cells were incubated with recombinant human recombinant TGF-beta1, TGF-beta2, and TGF-beta3., Main Outcome Measure(s): The cell proliferation, motility, and contractivity of ESCs were accessed by a modified methylthiazoletetrazolium assay, in vitro wound repair assay, transwell invasion assay, and collagen gel contraction assay., Result(s): All three isoforms of TGF-beta significantly inhibited the cell proliferation of ESCs in a dose-dependent manner. In vitro wound repair assay and transwell invasion assay demonstrated that the TGF-beta isoforms significantly inhibited the motility of ESCs. However, the TGF-beta isoforms were shown to have a clear effect on the collagen gel contractivity of ESCs., Conclusion(s): These results suggest that TGF-beta isoforms may promote endometrial tissue repair through the inhibition of the proliferation, expansion, and migration of ESCs, and through the stimulation of the contraction of the collagen gel matrix by these cells. Transforming growth factor-beta may be involved in the protection of the endometrium from extensive fibrosis and scarring by regulating ESC function during the perimenstrual period.
