1/3. Unusual petal-like fibromuscular dysplasia as a cause of acute abdomen and circulatory shock.fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory segmental arterial occlusive disorder that involves primarily the renal and carotid arteries, and less often the coronary, iliac, and visceral arteries. We report the case of 78-year-old Japanese woman who presented with acute abdomen complicated by shock. autopsy revealed hemorrhagic necrosis of the small intestine due to severe narrowing of the mesenteric arteries. Histologically, smooth muscles showed in-bundle hyperplasia surrounding the adventitia together with medial and perimedial fibrodysplasia of these arteries, forming the characteristic petal-like appearance of FMD. No occlusive thrombus was observed. Further, another medial fibrodysplasia type of FMD was also seen in the renal and left circumflex coronary arteries. Unusual proliferation of smooth muscles resulted in the petal-like atypical FMD at the superior mesenteric artery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/3. A case of a ruptured pheochromocytoma with an intratumoral aneurysm managed by coil embolization.Although the spontaneous rupture of adrenal pheochromocytoma is rare, it can be lethal because it can induce serious changes in the circulation. We describe a 32 year old man with bilateral pheochromocyroma presenting as abdominal pain. In the emergency room, an abdominal MRI showed an aneurysmal vessel in the right adrenal mass and accompanying hemorrhage around the tumor capsule. The bleeding site was found by transfemoral abdominal angiography. Coil embolization was done in the bleeding vessels, specifically branches of the right adrenal artery. The hemorrhage was successfully controlled and vital signs of the patient were restored. Following emergency care, biochemical and imaging studies showed compatible findings of a bilateral adrenal pheochromocytoma. Postoperative histologic findings confirmed these observations. A ruptured pheochromocytoma should be considered as a cause of acute abdomen in cases of a concomitant adrenal mass. Intratumoral aneurysmal bleeding may be a cause of ruptured tumor, and careful angiographic intervention will help to ensure safe control of bleeding in such an emergency situation, even in cases of bilateral tumor.- - - - - - - - - - ranking = 0.18207059729682keywords = circulation (Clic here for more details about this article) |
3/3. Emergency laparotomy immediately after coronary bypass.Eight patients required emergency laparotomy in the immediate postoperative period after coronary artery bypass (CAB). Cardiac complications were few and minor. sepsis was the major cause of mortality. In the two patients who died, delay in operative management contributed to their deaths. The lack of cardiac causes of morbidity and mortality in our series and others suggests that a stable postoperative coronary bypass patient represents a better surgical risk than the same patient preoperatively. Therefore, aggressive management, including early laparotomy, for suspected intra-abdominal pathology after CAB is recommended to avoid uncontrollable sepsis and death.- - - - - - - - - - ranking = 3keywords = coronary (Clic here for more details about this article) |
