Abstract Background Isolated splenic artery dissection (SAD) is extremely rare, life-threatening, and particularly difficult to diagnose. Moreover, SAD presenting as digestive hemorrhage has not been reported. Case presentation A 44-year-old man presented with recurrent life-threatening hematochezia. Magnetic resonance and computed tomographic angiography showed isolated SAD with an intrapancreatic hematoma. Selective angiography confirmed the diagnosis of rupture of SAD. Hemosuccus pancreaticus was considered the potential mechanism of digestive hemorrhage. It was successfully managed by endovascular coil embolization. Conclusions Isolated SAD is especially rare but fatal. Rupture of SAD should be considered in the differential diagnosis as a rare cause of digestive hemorrhage. Endovascular coil embolization is effective in treating ruptured SAD.

Isolated Innominate Artery

Abstract Background Acute DeBakey type I and type II aortic dissections are indications for emergent surgical repair; however, there are currently no standard protocols in the management of isolated supra-aortic dissections. Prompt diagnosis and management of an isolated innominate artery dissection are necessary to prevent distal malperfusion and thromboembolic sequelae. Case presentation A 50-year-old Caucasian gentleman presented with chest pain radiating to his jaw and right arm. He had no recent history of trauma. On physical exam, he was neurologically intact and malignantly hypertensive. Computed tomographic angiography of the chest and neck confirmed a spontaneous isolated innominate artery dissection without ascending aorta involvement. Given the lack of evidence for rupture, distal emboli, and/or end-organ malperfusion, the decision was made for initial non-operative management—anti-impulse regimen, antiplatelet therapy, and close follow-up. Conclusions Medical management of a spontaneous isolated innominate artery dissection is appropriate for short-term and potentially long-term therapy. This not only spares the patient from a potentially unnecessary surgical operation but also provides the surgeon and the patient the time to plan for a surgical approach if it becomes necessary.

Abstract This paper presents the novel development of highly porous carbon nanotube (CNT)/shape memory polymer (SMP) nanocomposites for potential endovascular treatment of intracranial aneurysms (ICAs). Intracranial aneurysm is a cerebrovascular disorder that can significantly weaken the wall of a brain artery, resulting in a localized dilation of the blood vessel with risk of rupture and subarachnoid bleeding. Current therapeutic options include surgical clipping and endovascular coil embolization. Clipping of intracranial aneurysms is invasive, and, therefore, it has gradually been replaced by non-invasive endovascular embolization. Recent studies have shown that aneurysmal recanalization and incomplete occlusion are still emerging clinical challenges in endovascular coil embolization. Therefore, there is an urgent need to develop new medical devices and surgical procedure to treat intracranial aneurysms with improved long-term outcomes. CNT/SMP nanocomposites are fabricated by directly coating CNTs on sugar particles before fabricating the sugar template for porous nanocomposites. Pristine SMP prepolymer is infiltrated into the pores of sugar template. All the sugar is dissolved in water after the fully curing of PDMS, resulting in SMP based nanocomposites with well dispersed CNTs. The porous nanocomposites are characterized to identify key parameters, such as electrical resistivity and shape memory capability. A resistive-heating mechanism is developed to trigger shape recovery of the nanocomposites. The results of this work will lay a solid foundation for our subsequent development of new personalized biomedical devices to treat ICAs using a catheter-based endovascular embolization procedure.

Tomographic Angiography

Congenital pulmonary venous anomalies are not uncommon that can occur either in isolation or in association with different forms of congenital heart disease. Clinical presentation of these anomalies may vary from the relatively benign single anomalous partial pulmonary venous return to life-threatening critical obstructed total anomalous pulmonary venous return. Accurate delineation of these anomalies and accompanied cardiovascular anomalies are crucial to guide decision making in these patients. Low-dose high-pitch dual-source 256-detector multidetector computed tomographic angiography is a fast and reliable imaging modality allowing comprehensive noninvasive anatomic imaging in neonates and children with congenital pulmonary venous anomalies with lower radiation doses and should be preferred for these patients after transthoracic echocardiography.

Transsphenoidal Resection

Abstract BACKGROUND AND IMPORTANCE: Prominent intercavernous sinuses may result in vigorous bleeding during transsphenoidal resection of pituitary microadenomas and lead to incomplete or aborted tumor resection. We report the use of coil embolization of the intercavernous sinuses to prevent uncontrollable bleeding before transsphenoidal surgery is reattempted. CLINICAL PRESENTATION: A 40-year-old man with Cushing disease underwent an attempt for transsphenoidal resection of an adrenocorticotrophic hormone--producing pituitary microadenoma. This approach was aborted secondary to profuse intercavernous sinus bleeding. The patient underwent endovascular coil embolization of the anterior intercavernous sinuses with complete obliteration. Six weeks later, he underwent successful transsphenoidal resection of the microadenoma. CONCLUSION: To the best of our knowledge, this is the first report of successful coil embolization of the intercavernous sinuses to prevent uncontrolled bleeding before transsphenoidal resection of pituitary microadenomas.
