A 64-year-old man presented to our emergency department with sudden onset of severe back pain 1 h ago. He had been physically well without history of hypertension or other systemic diseases. On physical examination, a significant difference between blood pressure in the upper and lower limbs was noticed (183/93 and 183/99 mmHg in the right and left upper extremity; 148/98 and 163/104 mmHg in the right and left lower extremity, respectively). Chest radiography showed a prominent aortic knob. Chest computed tomography revealed a Stanford type B aortic dissection associated with an aortic coarctation and persistent left superior vena cava [Figure 1]. Furthermore, the coarctation was found to coexist with tubular arch hypoplasia [Figure 2] and [Figure 3]. Considering the extreme age and high risk for surgery, medical treatment with angiotensin receptor blocker was given. The patient was in good physical condition after a 6-month follow-up.

Figure 2: Three-dimensional reconstruction of a computed tomography angiography. (a) Anterior view shows a Stanford type B aortic dissection (black arrowhead) with obvious anomaly of aortic arch. The aortic arch is seemingly interrupted in the middle and divided into proximal and distal portion after bifurcation of left subclavian artery (white arrow). The distal portion of the arch enlarges to a bulbous aneurysm. (b) Posterior view demonstrates a downward curving tubular hypoplasia (white arrowhead) which arises from the proximal portion of the aortic arch and funnels down toward the discrete coarctation (black arrow). The dissection shows the intimal flap originated from the distal portion of aortic arch (black arrowhead)

There were collateral vessels of dilated internal mammary arteries (white arrows) and intercostal artery (black arrow). pAo: Proximal portion of aortic arch, dAo: Distal portion of aortic arch

Aortic coarctation is an uncommon congenital luminal narrowing of the aortic arch which is commonly associated with cardiovascular abnormalities. Moreover, the persistent left superior vena cava is a rare vascular anomaly which is most commonly seen in isolation and could also be associated with coarctation of aorta [1]. By morphology, aortic coarctation is divided into two main types: discrete coarctation and tubular arch hypoplasia. These two types may coexist [2]. The average survival age of unrepaired aortic coarctation was 35 years of age with high mortality in advanced age. Without correction, coarctation resulted in high morbidity and mortality from hypertension, coronary heart disease, aortic dissection, heart failure, aortic rupture, and infective endarteritis [3].

Aortic dissection, especially type B, is rarely associated with coarctation. To the best of our knowledge, only 13 cases of aortic coarctation with type B dissection were reported with patients' ages ranging from 25 to 56 years [4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16]. The locations of coarctations were mostly distal to the left subclavian artery except one which was located between left carotid and subclavian arteries [15]. All the reported coarctations were discrete coarctations. Our case is unique not only of its extreme age but also of its discrete coarctation coexisting with tubular arch hypoplasia and persistent left superior vena cava.

Although uncomplicated type B dissection is well established to be treated conservatively, adult aortic coarctation is still considered a surgical candidate in the presence of peak-to-peak coarctation gradient >20 mmHg. The treatment for aortic coarctation included surgical repair, balloon angioplasty, and stenting [17]. While balloon angioplasty is the preferred treatment for discrete coarctation in infants and children between 4 months and 5 years of age (<25 kg), stenting is the first choice for larger patients (>25 kg). In the presence of complex coarctation anatomy such as arch hypoplasia, the decision to use balloon angioplasty or stenting versus surgical approach is made on a case-by-case basis. However, for the elderly concerning about the tissue integrity of the paracoarctation region with subsequent risk from complications of interventions, continued medical therapy with goal of controlling pressure gradient using beta-blocker, angiotensin-converting enzyme inhibitors, or angiotensin receptor inhibitors may be an acceptable option [18].
