Placement of stent grafts with different calibers into the true and false lumens of anastomotic aneurysms after descending aortic replacement for aortic dissection.

Anastomotic aneurysms present as a life-threatening emergency after descending aortic replacement for aortic dissection. Thoracic endovascular aneurysm repair (TEVAR) has been performed since the early 2000s for complicated cases in which re-thoracotomy cannot be adopted. We report the case of a 57-year-old male patient, during a 5-year follow-up after descending aortic replacement for aortic dissection, developed aneurysm expansion around the false lumen on the peripheral side of the artificial graft. Considering the risk and the patient's desires, we opted to perform TEVAR with different calibers into the true and false lumens "modified kissing stents technique". His postoperative course was uneventful without any complications. This case highlights the utility of the modified kissing stents technique for anastomotic aneurysms after descending aortic replacement for aortic dissection using stent grafts with different calibers into the true and false lumens.

A successful case of patch angioplasty with bovine pericardium XenoSure® to the common femoral artery after endarterectomy.

INTRODUCTION AND IMPORTANCE: The number of patients with chronic limb-threatening ischemia has increased in recent years. Herein, we report a rare case of angioplasty with a bovine pericardial patch in a patient with severe stenosis of the common femoral artery. CASE PRESENTATION: We report a case of a 73-year-old female with intermittent claudication. Ankle-brachial index (ABI) measurements showed a significant decrease of 0.52 on the left, and angiography revealed total occlusion on the left common femoral artery (CFA). Considering additional skin incisions, postoperative wound infection, and potential graft sampling, endarterectomy of the left CFA and patch angioplasty with the bovine pericardium (XenoSure®) were performed. The operative computed tomography showed no stenosis and the ABI improved from 0.52 to 1.15. Additionally, no stenosis, calcification, or dilatation was observed during the follow-up one year after the operation. CLINICAL DISCUSSION: Various types of peripheral arterial repair were performed after endarterectomy. Autologous vein grafts and vascular prostheses are frequently used considering the background of each patient. Using bovine pericardium over other devices has several advantages, including no additional skin incisions to obtain the patches, resistance to infection, no oozing from the device itself, less bleeding from the suture site, and ease of hemostasis after the puncture under additional endovascular treatment. This case may be a good implication when deciding which device to use in complicated patients. CONCLUSION: This case provides valuable insight into successful patch angioplasty after endarterectomy without any complications, highlighting the utility of XenoSure® in the treatment of this disease.

Surgical treatment of papillary fibroelastoma of the pulmonary valve: a case report.

BACKGROUND: Cardiac papillary fibroelastoma (PFE) is a rare tumor, and especially rare when found on the pulmonary valve. CASE PRESENTATION: We report the case of a 70-year-old woman patient with a pulmonary valve PFE diagnosed incidentally during a follow-up of aortic regurgitation. Computed tomography and magnetic resonance imaging showed no suggestive signs of malignant tumors, and thrombus or myxoma was initially suspected. However, an initial transthoracic and transesophageal echocardiogram did not exclude the possibility of a malignant tumor attached to the wall of the pulmonary artery. Considering the embolization risk, we opted to perform tumorectomy, in which additional surgical procedures could then be conducted if intraoperative diagnosis showed a malignant tumor. Indeed, intraoperative findings showed the tumoral mass attached on the left semilunar cusp of the pulmonary valve, and intraoperative diagnosis of the tumor showed no malignancy. Planned tumorectomy was performed concomitantly with AVR. The pathologic examination of the removed tumor confirmed the diagnosis of PFE. Her postoperative course was uneventful without any sign of recurrence. CONCLUSION: This case highlights the difficulty of accurate diagnostic imaging and provides valuable insight into a successful surgical treatment of pulmonary valve PFE without any complications.
