Embolo/sclerotherapy is an important treatment modality for vascular malformations, but the rates and results of the complications associated with embolo/sclerotherapy are not well known. We report the incidence and outcome of soft tissue injury and neuropathy after performing embolo/sclerotherapy for congenital vascular malformations (CVMs) classified according to the Hamburg classification. ⋯ Soft tissue injuries occurred in 11.9% of patients (68 of 573) and neuropathies occurred in 8.6% (49 of 573) after undergoing embolo/sclerotherapy. Most of these complications recovered by themselves (58.9% from soft tissue injury and 85.1% from neuropathy). Our results suggest that embolo/sclerotherapy has an acceptable incidence of soft tissue injury and neuropathy, when considering the effect that the CVM had on the quality of life before treatment, so embolo/sclerotherapy is recommended as a treatment modality for CVM.

Case Reports
Traumatic dissection and rupture of the abdominal aorta as a complication of the Heimlich maneuver.
Although the Heimlich maneuver is considered the best intervention for relieving acute upper airway obstruction, several complications have been reported in the literature. These complications can occur as a result of an increase in abdominal pressure leading to a variety of well-documented visceral injuries, including the great vessels. Acute abdominal aortic thrombosis after the Heimlich maneuver is a rare but recognized event; however, to date no case of traumatic dissection and rupture of the abdominal aorta has been described. We report the first known case, to our knowledge, of a traumatic dissection and rupture of the abdominal aorta after a forcefully applied Heimlich maneuver.

The concept of repeatedly connecting an extracorporeal blood pump to produce pancycle suprasystolic inflow pressures to ischemic limbs is introduced. Balloon catheters allow for limb isolation from the systemic circulation. In the acute phase, it is assumed that pressure is proportion to flow (Poiseuille's Law) and in the chronic phase that collateral growth is related to endothelial shear stress and wall tension. The primary objective was to establish that increased flow could be achieved through collateral circulation in animals and in man with extracorporeal limb hyperperfusion. The second objective was to develop and test an arterial access system capable of intermittent regional hyperperfusion similar in concept to intermittent hemodialysis. Finally, to demonstrate the translocation of these concepts into humans facing major limb amputation where all standard treatment options had been exhausted. ⋯ Blood flow through collaterals can be very significantly augmented by connection to an extracorporeal pump with isolation from the systemic circulation. The pancycle hyperperfusion can be safely repeated by implantation of an arterial access device. In the longer term, there is evidence of collateral development. When amputation is the only alternative, hypertensive extracorporeal limb perfusion should be considered.
